Embodiment

To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached Figure and specific embodiment are described in detail.

As shown in figure 1, a kind of method for displaying image for being applied to the first equipment provided in an embodiment of the present invention, Idiographic flow includes：

Step 101, the first equipment determines the first imaging parameters of the first image.

Wherein, the first equipment any one can have image to show work(for mobile phone, tablet personal computer, TV etc. The equipment of energy, the present invention is not limited this.First imaging parameters can be for showing appointing for the first image Meaning imaging parameters, the color attribute parameter of such as the first image, row's graph parameter that bore hole 3D is shown etc., The present invention is not limited this.And it is understood that the specific picture material of the first image is not limited equally.

Specifically, the first imaging parameters that the first equipment can determine the first image according to pre-setting.Citing For, can preset the functional relation of the first imaging parameters, the first equipment can according to functional relation, Calculate the first imaging parameters.Certainly, the parameter value of the first imaging parameters can also be outside the first equipment , the equipment being connected with the first equipment communication be sent to the first equipment.

Step 102, the first equipment determines mark bit map picture corresponding with the first imaging parameters of the first image.

It is emphasized that the first imaging parameters of mark bit map picture and the first image have corresponding relation, this It can be that direct correspondence can also be indirectly corresponding to plant corresponding relation.So-called direct correspondence refers to, flag bit Image directly indicates the parameter value of the first imaging parameters, and so-called indirect correspondence refers to, mark bit map picture refers to Some information is shown, and the first imaging parameters can be obtained by the information.For example, the first imaging parameters are On the function of picture number, the first imaging parameters can be obtained according to picture number, mark bit map picture is used for Picture number is indicated, and then after picture number is known by mark bit map picture, you can obtain the first imaging ginseng Number.

Step 103, the first equipment generates the first image according to the first imaging parameters of the first image, and will Mark bit map picture corresponding with the first imaging parameters of the first image is arranged on the precalculated position in the first image.

Wherein, precalculated position is not limited, and can be the optional position in the first image, for convenience mark bit map Mark bit map picture, can be arranged on the center of the first image by the crawl and identification of picture.

Step 104, the first equipment shows the first image for being provided with mark bit map picture, so that the second equipment is obtained The first image is taken, and according to the mark bit map picture set in the first image, determines the first imaging of the first image Parameter.

Method for displaying image provided in an embodiment of the present invention, because the first equipment sets mark in the first image There is corresponding relation, therefore, second in the first imaging parameters of bit image and mark bit map picture and the first image Equipment can synchronously get the first image and mark bit map picture, and then accurately be obtained by mark bit map picture First imaging parameters of the first image, that is, synchronous and accurately obtain the first image and the first image First imaging parameters.So, the first imaging parameters of any image of the first equipment actual displayed, all It can accurately be identified by the second equipment, effectively prevent the first image and second that the second equipment is got The nonsynchronous problem of the first imaging parameters for the first image that equipment is determined, is solved present in prior art Getting a side of image more can not accurately know the technical problem of image parameter of image.

It is described further below for above method flow.

In above method flow, the first imaging parameters of the first image can be and the first equipment display image Any one related imaging parameters of display performance.For example, the first equipment can show for bore hole 3D and set Standby, the second equipment can be the calibration equipment for correcting the first imaging parameters of the first equipment, and rear extended meeting is led to Specific embodiment is crossed to be described in detail.

In a kind of specific embodiment, the first imaging parameters can be the function of picture number, mark bit map As being used for identification image numbering, specifically, picture number can be frame number.For example, the first equipment will be circulated Some two field pictures are shown, each two field picture is using first imaging parameters, and the first equipment first can basis Preset or by the communication with external equipment, determine the first imaging parameters initial value and the first one-tenth As the rule change of parameter, for example, often showing a two field picture, the first imaging parameters increase a fixed step Long, i.e. the first imaging parameters are the function of frame number.

In this case, before the first imaging parameters that step 101 determines the first image, above method stream Journey also includes：Determine the picture number of the first image；Then, above-mentioned steps 101 are specifically included：According to first The picture number of image, determines the first imaging parameters of the first image；Above-mentioned steps 102 are specifically included： According to the picture number of the first image, mark bit map picture is determined, mark bit map is as identifying the first image Picture number, so that the mark bit map picture of the first image is corresponding with the first imaging parameters of the first image. Because there is one-to-one relationship, the first figure in the picture number of the first image and the first imaging parameters of the first image The mark bit map picture of picture is used for the picture number for identifying the first image, therefore, the mark bit map picture of the first image There is corresponding relation with the first imaging parameters of the first image.

In a kind of specific embodiment, mark bit map picture includes comparing intuitively digital picture.For example, such as The first image shown in Fig. 2, including the mark bit map picture that a display content is " 2 ", the mark bit map Image position is 2 in the lower right corner of the first image, the frame number for identifying first image, and the second equipment is being obtained After first image, if identify that numeral can determine that the frame number of the first image, and then according to the first image Frame number, determine the first imaging parameters of the first image.

In a kind of specific embodiment, for the ease of the mark bit map picture in the first image of identification, this implementation Example mode devises a kind of cleverly mark bit map picture.The mark bit map picture includes at least one region, generally For at least two regions, different regional location differences, the position in region is used for the numerical digit for identifying predetermined system, It is understood that the different weights of different numerical digit correspondences, wherein predetermined system can be the decimal system, Binary system, hexadecimal etc., the present invention are not limited this, and the color in region is used to identify numerical digit Numerical value.In this case, above-mentioned steps 102 are specifically included：According to the picture number of described first image, Determine the hex value that described image is numbered under the predetermined system；The number of each numerical digit in the hex value Value, determines in the mark bit map picture color in region corresponding with each numerical digit respectively；According to the flag bit The color in region corresponding with each numerical digit respectively in image, determines the mark bit map picture.

Wherein, numerical value of the mark bit map as represented by is not limited to decimal value, can be the number of a variety of systems Value, abbreviation hex value.No matter the numerical value of flag bit graphical representation why system, the ten of the numerical value and the numerical value Hex value can be converted by following relation：Wherein, N represents mark bit map picture institute Corresponding decimal value, X_iFor the numerical value of the numerical digit of system number represented in mark bit map picture, K be into (binary system, K is just 2) k to system^n-iThe corresponding weights of numerical digit are represented, n is the region in mark bit map picture Quantity, and i ∈ (0,1,2 ..., n).

For example, mark bit map picture shown in Figure 3, it is assumed that make a reservation for into binary system is made as, that is, indicate Bit image represents a binary number.Mark bit map picture is divided into upper left, lower-left, upper right, the region of bottom right 4, Each region can fill black, white 2 kinds of colors, and black is used for identification value 0, and white is used for identification value 1. 4 region representations, 4 numerical digits, upper left represents first of 4 bits, and upper right represents that 4 two are entered The second of number processed, lower-left represents the 3rd of 4 bits, and bottom right represents the of 4 bits Four.Different numerical digits corresponds to different weights, and the decimal value of the flag bit graphical representation is： n₁×2³+n₂×2²+n₃×2¹+n₄×2⁰.For example, when top left region is black, the number of the numerical digit is represented It is worth for 1, i.e. n₁=1, and top left region for white when, represent the numerical digit numerical value be 0, i.e. n₂=0, its His numerical digit is identical with this.

So that the mark bit map picture of above-mentioned example is used for identifying the frame number of the first image as an example, the first equipment is true first The hex value (i.e. binary value) of the fixed frame number, then according to the value of each numerical digit in the binary value, it is determined that The color in each region of mark bit map picture, so that it is determined that going out to indicate bit image.When the frame number of the first image is 1, The tetrad value of the frame number of the first image is 0001, i.e. n under binary system₁=n₂=n₃=0, n₄=1, i.e., should First of four 2 hex values, second, the 3rd, the 4th corresponding region should fill respectively it is black, It is black, black, white, so that the frame number of the flag bit graphical representation constituted is 1.According to each area in 4 regions The position in domain and the corresponding relation of each numerical digit, and the color in region corresponding with each numerical digit respectively, in each area The color that the region should be filled is filled in domain, and then can determine that the first image when the frame number of the first image is 1 In mark bit map picture, reference can be made to shown in Fig. 3.If first, second, the 3rd, the 4th correspondence Zonule fill black, black, white, black respectively, then the frame for the flag bit graphical representation that 4 zonules are constituted Number it is：0×2³+0×2²+1×2¹+0×2⁰=2.

It is understood that in other embodiments, the system of numerical value of the mark bit map as represented by is not limited, It can be not limited to for the arbitrary carry systems such as the decimal system, octal system, hexadecimal, the position distribution mode in region The upper left upper right lower-left bottom right distribution stated, can also be level or so sequentially be distributed, it is vertical be sequentially distributed up and down, The setting of any one distribution mode such as circular distribution, array distribution, regional location and numerical digit corresponding relation is simultaneously Above-mentioned setting is not limited to, can also be set otherwise, for example, mark bit map picture shown in Fig. 3, from the right side To the left high flexible strategy position for corresponding to hex value respectively from top to bottom to low flexible strategy position.

It should also be noted that, for clarity, each area limit of the mark bit map picture shown in Fig. 3 It is obvious, but in actual implementation, if after adjacent area filling same color, the boundary between region It may be affected, perhaps two area limit lines can not clearly distinguish.

In the mark bit map picture of above-mentioned example, including 4 regions, but the number in region that mark bit map picture includes Amount is not limited, and the numerical intervals that can be represented according to mark bit map as required for are configured.In this specific reality The position in each region is used for the numerical digit for identifying predetermined system in Shi Zhong, mark bit map picture, and the color in region is used In the numerical value of mark numerical digit, different colors represents different numerical value.It is understood that using mark bit map As the numerical value represented is relevant with the quantity in the region that mark bit map picture is divided into, if being divided into 4 regions, The numerical value that can be represented with 2 systems (2 kinds of Fill Colors) is 0 to 15；Carried out when needing logarithm value interval It during extension, can be extended with the quantity in region, mark bit map picture is such as divided into 6 regions, then 6 The numerical value of the numerical digit of 2 systems is with 0 or 1 mark, and the numerical value that can be represented is 0 to 63 (1×2⁵+1×2⁴+1×2³+1×2²+1×2¹+1×2⁰=63).

It is understood that with mark bit map picture represent numerical value size it is also relevant with system, and system with The quantity of the color of area filling is corresponding, and the color of area filling has 2 kinds under binary system, area under the quaternary The color of domain filling has 4 kinds, the like；If the quantity of holding area is constant, can by adjust into System increases the color of area filling to realize the extension of the numerical intervals to mark bit map as representated by.For example, If the system number of flag bit graphical representation 2, setting represents numerical value 0,1 respectively with black, white 2 kinds of colors.If The region that mark bit map picture is divided into is 5, and numerical digit is 5, then the numerical value area that can be represented with 2 systems Between be 0 to 31, maximum is：1×2⁴+1×2³+1×2²+1×2¹+1×2⁰=31.If setting mark bit map picture 4 system numbers are represented, 4 kinds of colors can be used：It is black, white, green, blue or green to represent numerical value 0,1,2,3 respectively, If the region that mark bit map picture is divided into is 5, numerical digit is 5, the then numerical value that can be represented with 4 systems Interval is 0 to 1023, and maximum is expressed as：3×4⁴+3×4³+3×4²+3×4¹+3×4⁰=1023.

Therefore, the numerical intervals that those skilled in the art can represent according to mark bit map as required for, are set Mark bit map is as corresponding system and the region quantity of mark bit map picture.Moreover, if necessary to mark bit map When being adjusted as the size of representative numerical intervals, by setting mark bit map as divided number of regions Amount, and/or system size (number of colors of each area filling in mark bit map picture), you can adjustment flag bit The scope of numerical intervals representated by image.

It is determined that after mark bit map picture, in step 103, the first equipment can be first according to the first image The first imaging parameters, generate the first image, then the mark bit map picture of determination and the first image are combined to, So as to which mark bit map picture is arranged in the first image.At step 104, show and be provided with mark bit map First image of picture.

So, the second equipment can synchronously get the first image and mark bit map picture, and then accurately The first imaging parameters of the first image are obtained by mark bit map picture, that is, synchronous and accurately obtain the First imaging parameters of one image and the first image.Obviously, the of any image of the first equipment actual displayed One imaging parameters, can accurately be identified by the second equipment, effectively prevent what the second equipment was got The nonsynchronous problem of the first imaging parameters for the first image that first image and the second equipment are determined, is solved existing There is the side for getting image present in technology more can not accurately know the image parameter of image Technical problem.

In practical application, method for displaying image provided in an embodiment of the present invention can be applied to the first equipment In the analysis and correction of one imaging parameters.Under this application scenarios, simplified summary is said, first equipment needs Generated using multiple the first different imaging parameters and show multiple first images, and the second equipment needs to obtain This multiple image and this multiple image distinguish corresponding first imaging parameters, and multiple images are analyzed to this, So as to analyze the first optimal imaging parameters value for showing that the first equipment is applicable.Based on this, the one of the present invention In individual specific implementation, the method for displaying image that the present invention is provided is further comprising the steps of：

So, the second equipment is generated with regard to that can get using different the first imaging parameters the first image and the Some images such as two images, and can get the first imaging parameters of these some images by mark bit map picture, And then can according to these images and the first imaging parameters of these images, obtain the first equipment be applicable it is excellent First imaging parameters of choosing.Because mark bit map picture corresponding with the first imaging parameters of each image difference is set In each image, the second equipment can synchronously and accurately obtain the first one-tenth of the first image and the first image As parameter, the first image that the second equipment gets and the first image that the second equipment is determined effectively prevent The nonsynchronous problem of first imaging parameters, so as to more accurately determine the first preferred imaging parameters.

First equipment generates and shows the specific process of the second image reference can be made to first being set in above-described embodiment The standby detailed process for generating and showing the first image, is not repeated herein.

So that method for displaying image provided in an embodiment of the present invention is applied in the trimming process of bore hole 3D equipment as an example At this moment, the first equipment is bore hole 3D display devices, and the second equipment is calibration equipment, and the first imaging parameters are Xoffadd (also referred to as claps graph parameter).The process for correcting the Xoffadd of bore hole 3D display devices is a circulation The process of traversal, bore hole 3D display devices circulation display is given birth to based on the Xoffadd according to certain rule change Into image, calibration equipment obtains the image of bore hole 3D display devices circulation display, and is set according in image The mark bit map picture put determines the Xoffadd of image, and true according to these images and these images Xoffadd The Xoffadd suitable for bore hole 3D display devices is made, so as to realize the purpose of correction.Using of the invention real The image display method of example offer, the first imaging of any image of bore hole 3D display device actual displayeds are provided Parameter, can all be corrected equipment and accurately identify, on the one hand, efficiently solve present in prior art The image of bore hole 3D display device actual displayeds to what 3D display devices were communicated may treat school with calibration equipment The positive asynchronous correspondence of the first imaging parameters causes the problem of correction accuracy is not good enough.On the other hand, it is not necessary to school Positive equipment, which is circulated to display device, sends Xoffadd values, and bore hole 3D display devices can be according to preset rules Change Xoffadd values, for example, so can effectively reduce calibration equipment from a fixed step-length is increased every time Communication interaction between bore hole 3D display devices, saves interaction cost.

Above-mentioned specific implementation is illustrated by taking Xoffadd as an example, but the first imaging parameters not limited to this, Can be with any parameter for being used to be imaged display of bore hole 3D display devices.

Based on identical inventive concept, corresponding with foregoing display methods embodiment, the embodiment of the present invention is also carried A kind of image analysis method for being applied to the second equipment supplied, wherein, the second equipment can be mobile phone, individual Any one has the equipment of data processing function with computer etc., and the present invention is not limited this, such as Fig. 4 institutes Show, image analysis method provided in an embodiment of the present invention, idiographic flow includes：

Step 401, the second equipment is obtained in the first image that the first equipment is generated and shown, the first image Mark bit map picture is provided with precalculated position.

Wherein, the first equipment generates according to the first imaging parameters of the first image and shows the first image, first The mark bit map picture set on image is corresponding with the first imaging parameters of the first image.

It should be noted that the display process and mark bit map picture of the first equipment have been carried out in detail above Illustrate, will not be described in great detail here.

Have specifically, the second equipment is settable in camera, this step, the second equipment is shot by camera The photo of the first equipment of the first image is shown, for example, the photo of the screen of the first equipment is shot, from And obtain the first image that the first equipment is generated and shown.

Certainly, the second equipment can also get the first image by other means, and the present invention is not limited this It is fixed.

Step 402, the second equipment determines the first image according to the mark bit map picture set in the first image First imaging parameters.

The mark bit map picture set in a kind of specific embodiment on the first image and the first of the first image Imaging parameters are corresponding to be referred to：First equipment determines the first imaging of the first image according to the numbering of the first image Parameter, mark bit map picture is used for the picture number for identifying the first image so that the mark set on the first image There is corresponding relation in the first imaging parameters of bit image and the first image.In this case, above-mentioned steps 402 Specifically include：Mark bit map picture is extracted from the precalculated position of the first image；According to the mark bit map picture of extraction, Determine the picture number of the first image；According to the picture number of the first image, the first one-tenth of the first image is determined As parameter.

Position of the mark bit map picture in the first image is pre-set, and the second equipment predicts the pre-determined bit Put.In order to extract mark bit map picture from the first image, the second equipment can determine the according to precalculated position first Indicate the approximate location of bit image in one image, mark bit map picture is then extracted according to the approximate location.Tool Body, the second equipment extracts mark bit map picture from the precalculated position of the first image to be included：

According to precalculated position, the first area in the first image is determined, first area includes mark bit map picture； The image of first area is extracted from the first image.

Because position of the mark bit map as shown in the display screen of the first equipment is fixed, i.e., in the first figure Position as in is fixed, and therefore, mark bit map picture is in the second equipment in the image that camera is captured Approximate location is also relatively fixed.Assuming that the display location of mark bit map picture be the center of the first image up and down The square area of positive and negative 50 pixels.When second equipment shoots the first image by camera, crawl The position of the mark bit map picture of image should also be answered in the central area of the image of crawl, flag bit image-region This is in wide high region of the picture centre captured by the second equipment relative to above-mentioned 2--3 times of square area It is interior.It thus can tentatively extract a region substantially --- first area, the region includes flag bit Image.The image acquiring device of the second equipment and the image display device of the first equipment can be so prevented effectively from Height or position there is caused second equipment during deviation to be difficult to be carried from the first image that the first equipment is shown Take mark bit map as the problem of.

Then, row threshold division is entered to the image of the first area of extraction.

The purpose of Threshold segmentation is for the edge contour of rising mark bit image.Mark bit map picture can be set Into the color in itself with the first image with significant difference.When entering row threshold division, typically refer to utilize pixel Gray value enter row threshold division, the gray value of pixel is generally between 0 to 255, to the first of extraction When the image in region enters row threshold division, threshold value can be set to 100, gray value is less than to 100 pixel ash Degree is set to 0, and the gray scale that gray value is more than to 100 pixel is set to 255.To the figure of the first area of extraction As the image entered after row threshold division is just called in bianry image, i.e. image just only two kinds gray values：Bai He It is black, so as to which the mark bit map picture in the image of the first area of extraction is come with background separation.

The determination of approximate region and Threshold segmentation processing are the preextraction of mark bit map picture, and the preextraction stage is In order to reduce the difficulty of flag bit image zooming-out.Next, mark bit map picture will accurately be extracted, from The edge contour of mark bit map picture is detected in the image of first area after Threshold segmentation, so as to divide from threshold value Mark bit map picture is extracted in the image of first area after cutting.Accurate extraction to mark bit map picture can be adopted Use following manner：

Utilize the conventional contour detecting algorithm of prior art, such as OpenCV contour detectings function pair preextraction Flag bit image-region carry out contour detecting, so as to obtain the general profile of mark bit map picture.Due to first The influence of the picture material of image in itself, therefore, removes the wheel of mark bit map picture in the profile that contour detecting is obtained Other interference profiles are there is likely to be outside exterior feature.Because the elemental area of mark bit map picture is pre-set Fixed value, and the contour shape of mark bit map picture is also what is pre-set, therefore can be according to the fixed value With the shape of mark bit map picture, profile screening is carried out, interference profile is excluded.Flag bit picture shape is usual Polygon, for example, quadrangle are set to, because the profile of the mark bit map picture detected is not standard Polygonal shape, accordingly, it would be desirable to be further processed, can be according to the mark bit map pre-set as shape Shape, disturbs the remaining profile after profile to carry out polygonal segments processing, so as to obtain flag bit to excluding The precise boundary position of image.And then according to resulting precise boundary position, extracted from the first image Mark bit map picture.Such as mark bit map picture is quadrangle, and the precise boundary position is four angle points of quadrangle Pixel coordinate, according to the pixel coordinate of four angle points, the mark of quadrangle is extracted from the first image Bit image.

In the case where mark bit map picture is digital picture, the second equipment extracts mark bit map picture, Ran Hougen According to the mark bit map picture of the extraction, the numeral in mark bit map picture is identified, so that according to identification Numeral, determines the picture number of the first image.Numeral identification can use existing known technology, here not Repeat again.

Include at least one region in mark bit map picture, the position in region is used for the numerical digit for identifying predetermined system, In the case of numerical value of the color in region for identifying numerical digit, the second equipment extracts mark bit map picture, it is determined that The color at least one region in the mark bit map picture of extraction；According to the color at least one region, it is determined that with The numerical value of the corresponding numerical digit at least one region；According to the numerical value of numerical digit, predetermined system hypograph numbering is determined Hex value；The hex value numbered according to predetermined system hypograph, determines the picture number of the first image.

Wherein it is determined that extract mark bit map picture at least one region color, specifically include：From mark The image at least one region is partitioned into bit image；Extract precalculated position at least one region being partitioned into Pixel pixel value；The average pixel value of the pixel value of the pixel extracted is calculated, by average pixel value It is used as the color value in region.

Wherein, the image at least one region is partitioned into from mark bit map picture, including：According to presetting The region by mark bit map picture position in mark bit map picture of quantity and each region, by mark bit map As being divided, the image of regional is obtained, if for example, the quantity of the flag bit area of mark bit map picture For 4, according to the upper left of mark bit map picture, lower-left, upper right, bottom-right location, by the mark bit map picture of extraction Averagely it is divided into the image in 4 regions.

Wherein, the pixel value of the pixel in precalculated position at least one region being partitioned into is extracted, including： For the image for any region being partitioned into, extraction is sized scope centered on the central point in the region Pixel in the range of interior image slices vegetarian refreshments, such as central point 3*3；It is determined that in the range of being sized The pixel color average value of image slices vegetarian refreshments；The average pixel value of the pixel value of the pixel extracted is calculated, will Average pixel value as region color value.Or, calculate average pixel value and any face in designated color Euclidean distance between colour, the pixel value of the minimum color of distance is defined as the color of the image in the region Value, wherein, the color specified refers to the color for representing the numerical value of each numerical digit in mark bit map picture.

For example, for the image for any region being partitioned into, extracting pixel in the range of heart point 3*3 in the picture Color, rgb value or gray value, then calculate the average pixel value of the pixel value of pixel in the range of 3*3, Seed point color value is used as with the average pixel value of the pixel value of pixel in the range of 3*3.Calculate seed point face The Euclidean distance between any color value in colour and designated color, by the pixel value of the minimum color of distance It is defined as the color value of the image in the region.

It is exemplified below.Mark bit map picture as shown in Figure 3, the bit of flag bit graphical representation 4, Including 4 regions, upper left, right regions and lower left region are black, and lower right area is white, black table Registration value 0, white represents numerical value 1.Second equipment identifies the color in this four regions respectively, and according to Color determines that the numerical value of corresponding numerical digit is distinguished in this four regions, so that a binary value 0001 is obtained, Then according to the corresponding weights of each numerical digit, decimal system conversion is carried out, the picture number for determining the first image is 1。

For another example the bit of flag bit graphical representation 4, including 4, first to fourth region region, Black table registration value 0, white represents numerical value 1.Second equipment determines first area, second area, the 3rd Region, four-range color are respectively black, white, black, white, it is determined that first area, second area, 3rd region, the numerical value of the corresponding numerical digit in the 4th region are respectively 0,1,0,1.If first area, second Region, the 3rd region, the corresponding numerical digit in the 4th region are respectively the 1st of binary number from back to front, the 2, the 3rd, the 4th, then the 1st corresponding weights use 2⁰Represent, the 2nd corresponding weights use 2¹ Represent, the 3rd corresponding weights use 2²Represent, the 4th corresponding weights use 2³Represent, then make a reservation for into The hex value 0101 of hypograph numbering processed is scaled the decimal system and is：0×2³+1×2²+0×2¹+1×2⁰, then basis The hex value of predetermined system hypograph numbering, it is determined that the picture number of the first image be 5.

Second equipment is obtained after picture number, by the picture number according to the first image, determines the first image First imaging parameters.Picture number and the first imaging parameters have certain functional relation, can be according to function Relation, the first imaging parameters are obtained using picture number.For example, for example, in a specific embodiment In, picture number is related to searching loop number of times, and the circulation of the first equipment shows the first image, and cycle-index is During first time, the first image parameter is initial value, and picture number is 1, when circulating second, picture number For 2, step-length ... the circulation n-th that the first imaging parameters increase by a fixation on the basis of initial value is, Picture number is N, and the first imaging parameters increase this on the basis of the value in previous i.e. N-1 times circulation to be fixed Step-length.First equipment often circulates display once, and the second equipment obtains the first image once, i.e. the second equipment Perform the behavior of a searching loop image.Obviously, mark bit map picture indicates picture number, picture number etc. Searching loop number of times is same as, in the case of the initial value of known first image parameter, the second equipment can root The first image parameter of each the first image is obtained according to picture number.

First equipment and the second equipment can arrange to set the first equipment in rule of communication, the rule of communication of agreement The traversal parameter of loop parameter and the second equipment, the initial of the traversal parameter of the first equipment, such as the first equipment follows Ring number of times (i.e. the traversal number of times of the second equipment), the initial value of the first imaging parameters, and the first imaging ginseng Number increases step-length certainly with when cycle-index is incremented by.First equipment carries out initialization and started after circulation process, often A two field picture is shown, cycle-index is incremental, the first equipment being shown to, cycle-index during the first image is used as The frame number (i.e. picture number) of one image, therefore, the second equipment determines the first figure according to mark bit map picture After the frame number of picture, according to the rule of communication of agreement, so that it may determine when the first equipment shows the first image First imaging parameters.

For above method flow in specific application, the first equipment shows each successively according to self-loopa flow Two field picture, the first one-tenth of each two field picture that the second equipment is shown to the first equipment successively according to self-loopa flow As parameter is identified.First equipment shows some two field pictures, and it is each that the second equipment is shown to the first equipment First imaging parameters of two field picture are identified, and then the second equipment can be from several first imaging parameters Determine the first optimal imaging parameters of the first equipment.

That is, the second equipment, which needs to circulate, obtains multiple first images, based on this, the one of the present invention In individual specific implementation, the image analysis method that the present invention is provided is further comprising the steps of：

Obtain and be provided with mark on the precalculated position in the second image that the first equipment is generated and shown, the second image Will bit image；

According to the mark bit map picture set in the second image, the first imaging parameters of the second image are determined.

Second equipment obtains the first equipment the second image for generating and showing, and according to being set in the second image Mark bit map picture, determines the specific implementation process of the first imaging parameters of the second image referring to above-described embodiment, It is not repeated herein.

Second equipment is when the first imaging parameters to the first equipment are analyzed, it usually needs set according to first The image of each frame of standby display determines the excellent of the first imaging parameters of each image.If the first equipment is shown Dry two field picture, the first imaging parameters of each two field picture that the second equipment is shown to the first equipment be identified into And the first optimal imaging ginseng suitable for the first equipment can be determined from several first imaging parameters Number.Therefore, the first imaging parameters of each two field picture that the second equipment is shown to the first equipment successively are known After not, it may also include：

Second equipment is according to the first image, the first imaging parameters of the first image, the second image and the second image The first imaging parameters, determine preferably the first imaging parameters of the first equipment.

How the embodiment of the present invention is for determine that preferably the first imaging parameters are not limited.For example, the second equipment The first image shown according to the first display device enters the 3D display effects of human eye, to the of the first image One imaging parameters are given a mark, and the 3D that the second image shown according to the first display device enters human eye is shown First imaging parameters of the second image are given a mark by effect, according to marking result, by the of the first image What score value was higher in one imaging parameters, the first imaging parameters of the second image is defined as preferably the of the first equipment One imaging parameters.

In above-described embodiment, the second equipment obtains the first image that the first equipment is generated and shown, the first image In precalculated position on be provided with mark bit map picture；According to the mark bit map picture set in the first image, it is determined that First imaging parameters of the first image.Because the first equipment is generated simultaneously according to the first imaging parameters of the first image Show the first imaging parameters of the mark bit map picture set on the first image, and the first image and the first image Corresponding, i.e. the second equipment can synchronously and accurately obtain the first imaging of the first image and the first image Parameter, solves and a side of image is got present in prior art more can not accurately know image Imaging parameters technical problem.

Image analysis method provided in an embodiment of the present invention can be applicable to the trimming process of bore hole 3D equipment.It is existing The imaging parameters and 3D display devices that calibration equipment determination is there is in the trimming process for having imaging parameters are actual The image of display is asynchronous, causes the problem of correction result is not accurate enough.It is a kind of in order to solve this problem In specific embodiment, the first equipment is bore hole 3D display devices, including display screen and is arranged on display Grating on screen, the second equipment is calibration equipment, and the first imaging parameters are any of bore hole 3D display devices Plant key parameter, such as Xoffadd.Bore hole 3D display devices are shown after the first image, calibration equipment according to The mark bit map picture set in first image determines the first imaging parameters of the first image, and 3D display devices are shown After second image, calibration equipment determines the first of the second image according to the mark bit map picture set in the second image Imaging parameters, the rest may be inferred.

The imaging parameters that calibration equipment is determined can be caused by above method flow, show and set with bore hole 3D The imaging parameters of the image of standby actual displayed are consistent, and the first of any image of 3D display device actual displayeds Imaging parameters, can all be corrected equipment and accurately identify, and then on the other hand, efficiently solve existing skill The image of bore hole 3D display device actual displayeds present in art may be with calibration equipment to 3D display devices The asynchronous correspondence of the first imaging parameters to be corrected of communication causes the problem of correction accuracy is not good enough.

With reference to the correct application scene of bore hole 3D display devices, show and set using the first equipment as bore hole 3D Standby, the second equipment is calibration equipment, exemplified by the first imaging parameters is row's graph parameter xoffadd values, to this hair The image display method and picture analyzing method that bright embodiment is provided are further elaborated.Wherein, it is naked Eye 3D display devices include the grating of display screen and setting on a display screen.As shown in figure 5, specifically including：

Step 1, calibration equipment sends the rule of communication of agreement to bore hole 3D display devices；

Calibration equipment starts correction program first, after initialization, and agreement is sent to bore hole 3D display devices Rule of communication.

Wherein, the rule of communication of agreement includes：

Graph parameter xoffadd initial value picth=6.64241 is arranged, row's graph parameter xoffadd's increases step-length certainly Xoffadd_step=0.2, searching loop number of times Iter=200 (maximum frame number)；

Make a reservation for into being made as 4 systems (i.e. mark bit map picture include 4 regions)；

The color in region is in vain, blue including black, blue or green, and numerical value 0,1,2,3 is represented respectively；

The viewing area of mark bit map the picture heart, wide a height of 100*100 pixels of viewing area in the picture；

The position in each region of mark bit map picture and the corresponding relation of numerical digit are：Mark bit map is as upper left region It is the 1st of quaternary number from back to front, the region in upper right side is the 2nd, and the region of lower left is the 3rd Position, the region of lower right is the 4th.

It is understood that optional, full content or department's content in rule of communication can also be first Preset and store in equipment and the second equipment, can not be by the side of this communication in the present embodiment Formula is transmitted.

Step 2：The rule of communication for the agreement that bore hole 3D display devices reception calibration equipment is sent, and according to The rule of communication of agreement is initialized；

Bore hole 3D display devices start in the rule of communication for receiving agreement, and rule of communication according to agreement Various parameters are initialized.

Step 3, calibration equipment sends correction instruction to bore hole 3D display devices, indicates that bore hole 3D is shown and sets The standby circulation process for starting traversal xoffadd values；

Step 4, bore hole 3D display devices receive correction instruction, start the traversal self-loopa stream of xoffadd values Journey, for current traversal number of times, performs following steps：

Determine the frame number of correction chart picture；

Determine the xoffadd values of correction chart picture；

According to the frame number of correction chart picture, mark bit map picture is determined；

Correction chart picture is generated according to the xoffadd values of correction chart picture, and the mark bit map picture of determination is arranged on The correction chart picture for being provided with mark bit map picture is shown behind the precalculated position of correction chart picture；

Wherein, in currently traversal number of times, generate and show correction chart as when, current traversal number of times is defined as The frame number of correction chart picture, such as, current traversal number of times is 27, then current frame number is 27；According to xoffadd_step It is worth on the basis of the xoffadd values in upper one traversal number of times from an xoffadd_step value is increased, determines and work as Preceding to travel through the corresponding xoffadd values of number of times, such as, the xoffadd values of upper traversal number of times are 3.0, then really The corresponding xoffadd values of traversal number of times are 3.2 before settled；It is determined that mark bit map as when, if current traversal time Number is 27, then it is 0123, i.e., 0 × 4 to determine the corresponding hex value of frame number 27³+1×4²+2×4¹+3×4⁰； It is then determined that the numerical value for going out each numerical digit in mark bit map picture when frame number is 27 is respectively 3,2,1,0, The color that the corresponding region of so each numerical digit should be filled is respectively blue or green (first), blue (second), white (the Three), black (the 4th)；Corresponding color is filled in regional, you can the mark that generation frame number is 27 Will bit image, as shown in Figure 6；It is 3.2 correction chart picture to generate xoffadd values, and by the mark of determination Bit image is arranged on the center of correction chart picture so that after the correction chart picture with mark bit map picture is shown, The a height of 100*100 of viewing area field width of mark bit map picture, what bore hole 3D display devices were shown carries mark bit map The correction chart picture of picture is as shown in Figure 7.

Step 5,, will be current if being not more than it is determined that currently whether traversal number of times is more than maximum traversal number of times Number of times is traveled through from increasing, next traversal number of times is obtained, above-mentioned steps are performed in next traversal number of times, if being more than, Then terminate traversal；

Step 6, calibration equipment starts self-loopa program, is shot by camera and shows the naked of correction chart picture The photo of the photo, such as display device screen part of eye 3D display devices；

For each photo photographed, following steps are performed：

Mark bit map picture is extracted from the precalculated position of correction chart picture；According to the mark bit map picture of extraction, school is determined The frame number of positive image；According to the frame number of correction chart picture, the xoffadd values of correction chart picture are determined；

Because the relative position of calibration equipment and bore hole 3D display devices is fixed, set therefore it may only be necessary to correct It is standby to get the position for indicating bit image in a two field picture, you can obtain the mark bit map of each two field picture as Position, also can directly extract mark bit map picture according to the position from each two field picture.Generally according to The first two field picture that bore hole 3D display devices are shown, to determine that each frame correction chart indicates bit image as in Position.

For example, when calibration equipment obtain the first frame correction chart as when, from the precalculated position of the first frame correction chart picture Mark bit map picture is extracted, is specifically included：According to precalculated position (central area 100*100 pixels), it is determined that First area in first frame correction chart picture, first area includes mark bit map picture；From the first frame correction chart picture In, extract the image of first area；Row threshold division is entered to the image of the first area of extraction；From threshold value point The edge contour of mark bit map picture is detected in the image of first area after cutting, so that after Threshold segmentation Mark bit map picture is extracted in the image of first area.Determine edge contour, you can determine mark bit map Position of 4 angle points of picture in the first frame correction chart picture, preserves the positional information of this 4 angle points, subsequently When flow indicate in other frame correction chart pictures the extraction of bit image, all in accordance with this 4 angle points of preservation Positional information extracts the mark bit map picture in correction chart picture.

After mark bit map picture is extracted, calibration equipment splits mark bit map picture according to the rule of communication of agreement For the image in 4 regions, for the image for any region being partitioned into, in the picture in the range of heart point 3*3 Extract pixel color, then rgb value or gray value calculate the flat of the pixel value of pixel in the range of 3*3 Equal pixel value, seed point color value is used as with the average pixel value of the pixel value of pixel in the range of 3*3.Meter The Euclidean distance between any color value in seed point color value and designated color is calculated, by the face that distance is minimum The pixel value of color is defined as the color value of the image in the region.If first area, second area, the 3rd region, Four-range color is respectively green grass or young crops, blue, in vain, black, first area, second area, the 3rd region, the The corresponding numerical digit in four regions is the 1st, the 2nd, the 3rd, the 4th；Then the 1st, the 2nd, 3rd, the numerical value of the 4th be respectively 3,2,1,0, i.e. the hex value of the frame number of flag bit image identification For 0123, decimal system conversion is carried out, it is 27 as corresponding frame number to determine mark bit map, i.e., 27=0 × 4³+1×4²+2×4¹+3×4⁰.Finally according to frame number 27 and the corresponding relation of xoffadd values, it is determined that Go out the corresponding xoffadd values of frame number 27, xoffadd values=initial value+(frame number -1) * step-lengths of each two field picture.

Step 7：Judge whether the value of frame number is more than defined maximum frame number, if being more than, terminate traversal, Perform step:8；If being not more than, above-mentioned steps are continued executing with.

Step 8：Calibration equipment determines optimal xoffadd values from multiple xoffadd values.

For example, calibration equipment simulation human eye determines the aobvious of each two field picture that bore hole 3D display devices are shown Show effect, according to the display effect of each frame correction chart picture, to each frame correction chart xoffadd as corresponding to Value is given a mark, and regard marking value highest xoffadd values in all frame correction chart pictures as optimal xoffadd Value.

How the present invention from multiple xoffadd values for determine that optimal xoffadd values are not limited, originally Art personnel can use existing known technology.

Above method flow compared with prior art, with following technique effect：
