Frame system；
Wherein described active LED light source device is parallel with cam device, necessary for being provided to pending paper portions
Light source requirements；
The smart camera processing system, including：
Camera, for gathering the desktop field-of-view image to be shot in real time；
Image processor, the image collected for handling camera, send instruction control adjustment of camera focal length size
Cut out with to interesting target window, and calculate the relative of the paper target area interested after image processor is cut out and incline
Rake angle, after the adjustment that respective angles are carried out to target area, amplified operation causes interesting target to be partially filled with entirely throwing
Shadow screen；
The video flowing output control system is used to realize to shooting paper target area interested fixed window size
Real-time Data Transmission and display；
The movable connecting rod rack system of multi-joint is used to fastening and supporting video camera and light supply apparatus, and by collection
Video stream information is gone out by data wire real-time Transmission.
The control method of portable translucent correction based on the equipment, comprises the following steps：
System controls light source to illuminate the target area of paper；
Camera carries out IMAQ to target area；
Described image is handled, and controls camera adjustment focal length, interesting target window cut out and adjusted mesh
The angle in region is marked, makes it full of video frequency output window to be shown.
Further, the step also includes：Index point is provided with wherein three angles of paper, the camera collects
Paper information, and judge whether the paper profile index point is complete.
Further, if the paper profile index point is imperfect, by adjusting focal length, and then make it that paper areas is complete
Entirely in camera view.
Further, if the paper profile index point is complete, the index point area image is cut out, and it is right
Image does the adjustment at corresponding angle of inclination so that interesting target region is full of projection screen.
Wherein, the active light source is LED；The hardcore of the smart camera processing system is camera, totally one
Set, is placed in parallel with LED light source and is installed on fixed support front end.
The movable connecting rod rack system of multi-joint can be made up of a fixed turn dop and three connecting rods, turn
Dop is by screwdriver fastener on table angle.Three connecting rods extended out are by the bar of two pitching functions and a rotation
The bar composition of function, it is possible to achieve cam device freely converting of putting of orientation on the table.
Pixel letter is shown in the image-region of the camera collection of the smart camera processing system in digitlization
Breath, the paper on desktop is shown in the camera and pixel information, making contrast using both borders collected can be with
Angle of inclination between the two is analyzed, the paper image information for then making to collect carries out corresponding angle rotation.
The smart camera processing system can also determine whether to change paper in addition to specific objective is acquired.Take the photograph
The continuous refresh picture of camera, if present frame and former frame are judged as changing paper, weight there occurs the variable quantity more than threshold value
It is new to carry out paper position and size judgement.
The video flowing output control system is cut out through smart camera processing system and postrotational paper receiving
After opening information, now need to compare the paper size after cutting out and normal video output window size, if after cutting out
Antiquarian is less than normal video output window size, then does corresponding enhanced processing.Final purpose is to make the paper after cutting out
Open region and be full of whole video frequency output window just.In smart camera processing system, video camera and image processor are carried out
Data real-time, interactive.
Preferably, index point is provided with wherein three angles of paper, the camera collects paper information, and judges institute
Whether complete state paper profile index point.Three index points are portrayed in three corners of paper with specific seal, between this index point
Line be to characterize paper region feature.This approach avoid caused by paper and desktop color are close can not
Error extraction caused by differentiation, while reduce the dependence to certain paper.
Described image processing operation is divided into two stages, and the first stage includes initial treatment image and sent to instruct control to take the photograph
Camera adjusts focal length size；Second stage：Interesting target region is cut out and carried out accordingly to cutting back zone area image
Angle rotation and enhanced processing.
Compared by the image to paper areas and video camera boundary pixel, so calculate now paper relative to regarding
The angle of inclination of field border, corresponding angle rotation is made according to this.
It also includes making cut out areas size adjustment.If the paper information after cutting out is less than normal video output window
Size, then do corresponding enhanced processing.Final purpose be to make the paper information after cutting out lucky be full of whole video frequency output
Window, the perception effect best to spectators.
Reference picture 2, correct system for a kind of portable translucent of the utility model, the mark sheet that the implementation of equipment uses
Open and camera fields of view relative status schematic diagram.Wherein outside solid box represents camera fields of view, and middle solid box represents paper position.

Image detection needs.Using image detection correlation technique, the center intersection point of spider is found, and respectively by upper left and upper right
Central point connection is in alignment 1, the central point connection in alignment 2 of upper left and lower-left, is then based on the friendship of upper right spider
The parallel lines of straight line 1 and 2 is done in point position, that is, obtains area-of-interest.Interesting target region and camera coverage relative angle
For θ.Pixel information, table is shown in the image-region of the camera collection of the smart camera processing system in digitlization
Paper on face is shown in the camera and pixel information, making contrast using both borders collected can analyze
Angle of inclination between the two, the paper image information for then making to collect carry out corresponding angle rotation.
Reference picture 3, for a kind of portable translucent correction system of the utility model, the workflow diagram of the realization of equipment.Firmly
Part device is built activation system after completion, and now LED light source lights for being illuminated to target area, camera work, to mesh
Mark region and carry out video flowing collection, and whether opened according to image overall intensity effect detection light source or whether illumination is sufficient, it is no
LED light source will then be restarted or improve light source power.Camera collects desktop paper information, judges whether paper profile index point is complete
It is whole, if imperfect will adjust camera focus so that paper areas is all in camera fields of view；Start if normal to mark
Image is cut out in point region, and the adjustment of corresponding angle of inclination and size is done to it, and video information is filled by projecting
Put and transfer out for showing.This process will do whether change paper judgement to collection image in real time, if not changing paper, no
Make camera parameter adjustment；Otherwise, then refresh parameter, re-searches for desktop paper.
Reference picture 4, for a kind of portable translucent correction system of the utility model, the control of the paper areas position adjustment of equipment
Flow chart processed., will be to mark point in image-region after camera acquisition to video image, i.e., the feature cross that marks in advance
Fork is detected, after angle point grid is carried out to position of intersecting point in spider, accurately find out the pixel coordinate position of spider intersection point
Put, and count；If three spider position of intersecting point extract successfully, as shown in Figure 2, three position of intersecting point are connected with each other,
Area-of-interest is determined, and the region is contrasted with camera fields of view, the relative dip angle of area-of-interest is calculated and regards
Wild scaling, after do corresponding angle adjustment and enhanced processing to interesting target region, the picture after most adjusting at last is thrown
