Description

The present invention relates to a measurement data collecting device and a program that collects measured values by analyzing an image of a measuring tool on which measurement results are displayed.

The measured value by a measuring tool such as a caliper, a micrometer, or a dial gauge is generally read directly from the measurement result displayed on the measuring tool on a display or a scale, or indirectly by a reading method peculiar to each measuring tool. Can be done. In the case of an analog measuring tool, the measurement data is collected by transcribing the read measured value on paper or inputting the measured value into a personal computer. In the case of a digital measuring tool, in addition to the same method as the analog measuring tool, the measurement data that has been electrically signal-processed is transferred to a personal computer by wired communication or wireless communication. Examples of the device for collecting measurement data using a digital measuring tool include those described in Patent Documents 1 and 2.

When collecting measurement data, with analog measuring tools, there is a risk of the trouble of transcribing the measured value on paper or inputting it to a personal computer, and the risk of mistakes during transcription input, and both hands are blocked during measurement. Since it is difficult to record the measured value while measuring, the measured value must be recorded each time the measurement is performed, and the workability is not good because continuous measurement cannot be performed. On the other hand, with a digital measuring tool, it is relatively easy to collect measurement data and almost no transfer error occurs, but it is more expensive than an analog measuring tool because it is equipped with a CPU and a communication function. In addition, the cable becomes an obstacle when transferring data by wired communication.

It may be configured to read the measured value from the external image of the target measuring tool. The tool specific information may be all or a part of the appearance image of the measuring tool, or may be identification information that can be read directly or indirectly from the appearance image of the measuring tool. In the case of the identification information, the tool identification means directly or indirectly reads the identification information from the external image of the target measuring tool and collates it with the tool identification information. With this configuration, the type of measuring tool can be determined from the external image and the measured value reading method can be selected according to the type, so that it is possible to read the measured values for a plurality of types of measuring tools. Become.

The tool identification information storage means further stores the tool identification information for each individual measuring tool, the tool identification means further identifies the individual of the target measuring tool, and the individual measuring tool specified by the tool identifying means Further, a reading control means for issuing a predetermined warning and / or controlling not to read the measured value by the measured value reading means may be further provided.

[First Embodiment]
FIG. 1 is a diagram showing a configuration example of the measurement data collecting device 100 according to the present embodiment. The measurement data collecting device 100 includes an imaging means 101, a measured value reading means 102, a tool specifying information storing means 103, a tool specifying means 104, a reading method storing means 105, and a reading method specifying means 106.

The imaging means 101 images the appearance of the target measuring tool on which the measurement result is displayed. Generally, a camera that captures a still image is assumed to be used as the imaging means 101, but since it is sufficient that the still image is finally output, for example, the still image is extracted from the moving image and output. A video camera or the like may be used. The target measuring tool is a measuring tool for which the measured value is read by the measurement data collecting device 100, and any tool may be used as long as the measurement result can be visually recognized from the appearance. In the case of a digital measuring tool, the measurement result is the measured value itself, but in the case of an analog measuring tool, it is an object that reads the measured value, and is generally expressed by a scale or the like. Since it is necessary to read the measurement result from the appearance image, the image of the appearance by the imaging means 101 needs to be performed at least in the range and the resolution necessary for reading the measurement result. For example, when the target measuring tool is an analog type caliper 10 as shown in FIG. 1, it is necessary that at least the portion surrounded by the dotted line is imaged in a range and resolution such that the scale can be read.

The measured value reading means 102 reads the measured value from the external image of the target measuring tool captured by the imaging means 101. A method of reading the measured value from the external image will be described by taking each measuring tool shown in FIGS. 2 to 4 as an example.

FIG. 2 is an excerpt of a portion where the measurement result of the caliper 10 is displayed. The caliper 10 sandwiches an object for dimensional measurement between a main scale 10a and a slider 10b slidably provided in the longitudinal direction of the main scale 10a, and measures the sandwiched width t. The measured value is read from the relative positional relationship between the main scale scale swayed every 1 mm on the main scale 10a and the vernier scale swayed every 1.95 mm on the slider 10b.

Specifically, the integer part of the measured value is read by grasping where the 0 scale on the leftmost side of the vernier scale points to the main scale scale. That is, if the 0th scale on the leftmost side of the main scale is the 0th scale and the 0th scale of the vernier scale points between the nth scale and the n + 1th scale, the integer part of the measured value is n. Can be read. In the example of FIG. 2, since the 0 scale of the vernier scale points between the 16th main scale scale and the 17th main scale scale, it can be read that the integer portion is 16 mm. In addition, the vernier scale at which the main scale scale and the vernier scale are in a straight line is read in 0.05 mm units after the decimal point of the measured value by grasping the scale with the 0th scale as the 0th scale. In the example of FIG. 2, since the third vernier scale is in a straight line, it can be read as 3 × 0.05 = 0.15 mm. From the above, the measured value can be read as 16.15 mm.

When reading the measured value from the appearance image, the measured value can be read by analyzing the image in the same manner. For example, first, an external image of the target measuring tool is obtained based on the position information of the 0 scale of the main scale in the appearance of the measuring tool of the type of the target measuring tool prepared in advance by the measured value reading means 102 or provided by others. Grasp the existence of the 0th scale from. Subsequently, the measured value is read from the appearance image based on the measured value reading method of the measuring tool of the type of the target measuring tool prepared in advance by the measured value reading means 102 or provided by others. Specifically, the appearance image around the main scale scale is scanned in the direction in which the number of the scale increases while counting the number of scales from the grasped 0th main scale scale, and the existence of the 0th vernier scale is detected. Then, it is specified that the main scale scale pointed to by the vernier scale is between the nth and n + 1th scales, and the integer part of the measured value is read as n. Here, if the main scale scale and the vernier scale are already in a straight line, it is read that the decimal point of the measured value is 0, and in other cases, the appearance image is further counted while counting the number of vernier scale scales. If the part where the main scale scale and the vernier scale are in a straight line is detected, specify the number of the vernier scale of that part, and if it is the mth, multiply m by 0.05. Read the measured value after the decimal point.

FIG. 3A is a diagram showing the appearance of the micrometer 20 which is an example of an analog type micrometer, and FIG. 3B is an excerpt of a portion where the measurement result of the micrometer 20 is displayed. The micrometer 20 sandwiches an object for dimensional measurement between the anvil 20a and a spindle 20b that can expand and contract in the axial direction by rotating the thimble 20d around the sleeve 20c, and measures the sandwiched width t. The measured value is read from the relative positional relationship between the sleeve scale swung every 0.5 mm on the sleeve 20c and the thimble scale swung every 0.01 mm on the thimble 20d.

Specifically, first, the measured value is read in units of 0.5 mm depending on which scale is exposed, with the 0 scale on the leftmost side of the sleeve scale as the 0th scale. In the example of FIG. 3B, since the 11th sleeve scale is exposed, it can be read as 11 × 0.5 = 5.5 mm. Further, a value of 0 mm or more and less than 0.5 mm to be added to the value shown on the sleeve scale is read depending on where the reference line 20e of the sleeve 20c points on the thimble scale. The reading is performed, for example, based on the scale on which the nearest number is assigned from the thimble scale pointed to by the reference line 20e, and the number of the scale from that scale. The thimble scale is numbered every 5 scales from the 0th scale to the 49th scale. Since the scale is swayed every 0.01 mm, the actual value is 0.01 times the number on each scale. In the example of FIG. 3B, the number on the scale showing the number closest to the thimble scale pointed to by the reference line 20e is 0, that is, the 0th scale, and the reference line 20e is the number on the scale from there. Since it points to the first scale in the direction of increasing, 0 + 1 = 1 corresponds to the first scale as a whole. Therefore, the value to be added to the value shown on the sleeve scale is 1 × 0.01 = 0.01 mm. From the above, the measured value can be read as 5.51 mm. If the number of the scale showing the number closest to the thimble scale pointed by the reference line 20e is 45, and the reference line 20e points to the second scale in the direction in which the number of the scale decreases from there. Then, 45-2 = 43, which corresponds to the 43rd scale as a whole. Therefore, the value to be added to the value shown on the sleeve scale is 43 × 0.01 = 0.43 mm. Therefore, in this case, the measured value can be read as 5.93 mm.

When reading the measured value from the appearance image, the measured value can be read by analyzing the image in the same manner. For example, first, from the appearance image of the target measuring tool based on the position information of the 0 scale of the sleeve in the appearance of the measuring tool of the type of the target measuring tool prepared in advance in the measured value reading means 102 or provided by others. Grasp the existence of the 0th sleeve scale. Subsequently, the measured value is read from the appearance image based on the measured value reading method of the measuring tool of the type of the target measuring tool prepared in advance by the measured value reading means 102 or provided by others. Specifically, the appearance image around the sleeve scale centered on the reference line 20e is scanned in the direction in which the number of the scale increases while counting the number of scales from the 0th sleeve scale grasped, and the end of the thimble. When is detected, the thimble scale exposed at that time is specified to be the nth, and n is multiplied by 0.5 to read the measured value in 0.5 mm units. In addition, the number m of the thimble scale shown closest to the thimble scale pointed by the reference line 20e is scanned and grasped, and the number of scales is counted from the grasped mth thimble scale. The reference line 20e is detected by scanning the appearance image around the thimble scale in the direction of increasing (or decreasing). Then, the thimble scale pointed to by the detected reference line 20e is specified from the m-th thimble scale, and if it is the second, m + 2 is multiplied by 0.01 to measure the measured value in units of 0.01 mm. Read the value.

Since the thimble 20d rotates continuously, the position where the reference line 20e points to the thimble scale does not always coincide with the scale. The method of reading the value in such a case is arbitrary, and for example, a method of reading more finely or treating it as pointing to a scale closer to whichever is closer can be adopted.

FIG. 4A is a diagram showing the appearance of the digital caliper 30, which is an example of the digital caliper, and FIG. 4B is an excerpt of a portion where the measurement result of the digital caliper 30 is displayed. In the digital caliper 30, the measured value is directly displayed on the display unit 30a. Therefore, when reading the measured value from the external appearance image, for example, first, the position information of the display unit 30a in the appearance of the measuring tool of the type of the target measuring tool, which is prepared in advance by the measured value reading means 102 or provided by others, is used. Based on this, the existence of the display unit 30a is grasped from the external image of the target measuring tool. Subsequently, the measured value is read from the appearance image based on the measured value reading method of the measuring tool of the type of the target measuring tool prepared in advance by the measured value reading means 102 or provided by others. Specifically, the numerical value of each digit displayed on the display unit 30a of the target measuring tool is compared with the shape of the numbers 0 to 9 peculiar to the display unit 30a of the measuring tool of the type of the target measuring tool, and the target measurement is performed. The measured value is read by specifying the numerical value of each digit displayed on the display unit 30a of the tool.

Even if the measurement value reading means 102 is configured to issue a warning that the measurement result cannot be read when the appearance is not captured by the imaging means 101 within the range and resolution required for reading the measurement result. Good. In addition, if the configuration is such that the imaging is automatically retried when the image cannot be read, the image is read when the image becomes readable, and a warning is issued when the image is retried a predetermined number of times and the image cannot be read. It may be configured to do so. Whether or not it is unreadable is determined by analyzing the captured image, for example, if there are no pixels equal to or greater than the threshold value between the scale lines.

When there is only one type of the target measuring tool, it is not necessary to specify the type of the measuring tool or the method of reading the measured value according to the type. Therefore, the measured value reading means 102 is a measuring tool of the type prepared in advance. Based on the measured value reading method, the measured value is read from the measurement result displayed on the external image.

On the other hand, when there are a plurality of types of target measuring tools, it is necessary to specify the type of measuring tool and the method of reading the measured value according to the type. Therefore, the tool specific information storage means is placed in front of the measured value reading means 102. 103, a tool specifying means 104, a reading method storage means 105, and a reading method specifying means 106 are further provided.

The tool specific information storage means 103 stores tool specific information for each type of measuring tool. The tool specific information is identification information that can be directly or indirectly read from, for example, an external image of a measuring tool or an external image of a measuring tool. The identification information is, for example, the name, model number, serial number, etc. of the type of measuring tool. When the appearance image of the measuring tool is stored, the appearance image to be stored may be an entire image of the measuring tool or a part of a characteristic image that can identify the measuring tool. Further, it may be a two-dimensional image or a three-dimensional shape model. While the two-dimensional image can be easily prepared, when the appearance of the target measuring tool is imaged, if the image is taken at an angle significantly different from the imaging angle of the appearance image stored in advance in the tool identification information storage means 103, the tool identification means 104 There is a possibility that the images cannot be matched well at the time of image matching. On the other hand, although the three-dimensional shape model is not easy to prepare, it is possible to compare the appearance images of one type of measuring tool with the appearance images of a plurality of angles at the time of collation by the tool identification means 104, so that the collation error. And errors can be reduced.

The tool specifying means 104 identifies the type of the target measuring tool by collating the external image of the target measuring tool with the tool specifying information stored in the tool specifying information storing means 103. Since the object to be specified is the measuring tool itself, the image of the appearance by the imaging means 101 is performed by collating not only the part where the measurement result is displayed but also the tool specifying information stored in the tool specifying information storage means 103 with the measuring tool. It should be done in a range and resolution that can identify the type of. When the tool specific information is an external image of the measuring tool, the entire external appearance of the target measuring tool does not necessarily have to be imaged, and if it can be collated by a part of the characteristic appearance, the part is included in the imaging range. It is enough if it is included. When the appearance image of the measuring tool is a three-dimensional shape model, the appearance image from a plurality of viewpoints that can be extracted from the three-dimensional shape model is used for collation with the appearance image of the target measuring tool in the tool identifying means 104. It becomes possible to do it. On the other hand, when the tool identification information is the identification information, the tool identification means 104 reads the identification information directly or indirectly from the external image of the target measuring tool. That is, when the identification information is directly described on the measuring tool, the described portion is read from the external image. When the identification information is indirectly described on the measuring tool with a logo mark, a bar code, a QR code (registered trademark), or the like, the identification information is read from the external image via these marks or codes.

The reading method storage means 105 stores the measurement value reading method from the external appearance image for each type of measuring tool. Examples of the information to be stored as the measurement value reading method include a method of reading the measured value from the position of the display portion of the measurement result in the appearance of the measuring tool and the measurement result. Specific examples of the method for reading the measured value from the measurement result are as described above with reference to FIGS. 2 to 4. Then, the reading method specifying means 106 identifies the measured value reading method corresponding to the type of the measuring tool specified by the tool specifying means 104 with reference to the reading method storage means 105.

Finally, the measured value reading means 102 reads the measured value from the external image of the target measuring tool by the measured value reading method specified by the reading method specifying means 106. The read measured value is stored in, for example, the measured value storage means 100a. As the measured value storage means 100a, it is generally assumed that a permanent storage means such as a hard disk, a removable disk, or a memory card is used, but if necessary, a temporary storage means such as a semiconductor memory is used. It doesn't matter.

With the above configuration, the type of measuring tool can be specified from the external image and the measured value reading method can be selected according to the specified type. Therefore, the measured values can be read for a plurality of types of measuring tools. Is possible. Further, even when the types of measuring tools to be used increase, the information of the measuring tool newly added to the tool specific information storage means 103 and the reading method storage means 105 can be simply added without changing the overall configuration of the device. Can be accommodated.

The measured value read by the measured value reading means 102 may be displayed on the display means 100b. As a result, the measured value can be visually recognized as a numerical value even when an analog measuring tool is used. In this case, in particular, it contributes to the improvement of work efficiency of the user who does not know how to read the measured value from the scale or cannot read it smoothly.

Further, the tool identification information storage means 103 further stores the tool identification information for each individual of the measuring tool, the tool identification means 104 further identifies the individual of the target measurement tool, and the measurement specified by the tool identification means 104. Depending on the individual tool, a reading control means 107 may be further provided to issue a predetermined warning to the display means 100b or the like and / or to control the measured value reading means 102 not to read the measured value. Calibration of the measuring tool is usually performed by the management department (in charge) of the measuring tool, and it is generally not performed every time the operator uses it, so if it is not possible to thoroughly manage it in a small company etc. It is possible to measure with an expired measuring tool. Therefore, by adopting such a configuration, it is possible to take safety measures such as checking whether the specified measuring tool has been calibrated and giving a warning, and not reading the measured value when the calibration has expired. Management man-hours can also be reduced.

FIG. 5 is a diagram showing a configuration example of the measurement data collecting device 200 according to the present embodiment. The measurement data collecting device 200 includes an imaging means 101, a measured value reading means 102, a tool specifying information storage means 103, a tool specifying means 104, a reading method storage means 105, a reading method specifying means 106, a frame 201, an instruction input means 202, and The instruction recognition means 203 is provided. That is, the measurement data collecting device 200 includes the measurement data collecting device 100 with the frame 201, the instruction input means 202, and the instruction recognition means 203 added.

The frame 201 is attached to the head of the user of the measurement data collection device 200. The frame 201 is provided with an imaging means 101 in a direction in which a scene in the field of view of the user wearing the frame 201 is imaged. As a result, the user wearing the frame 201 on the head directs his / her line of sight to the target measuring tool for the measurement operation by the target measuring tool, so that the user can image the target measuring tool without using his / her hands. The imaging means 101 can be oriented in the same direction. The shape of the frame 201 is arbitrary as long as it can be attached to the head and the imaging means 101 can be provided.

The instruction recognizing means 203 recognizes the instruction content for each means input to the instruction input means 202, and each means executes a predetermined process according to the instruction content. For example, when the instruction "imaging" is input, the instruction recognizing means 203 recognizes the instruction and gives an imaging instruction to the imaging means 101, and when the instruction "save" is input, the instruction recognizing means 203 Recognizing the instruction, the measurement value reading means 102 is instructed to store the measured value in the measured value storage means 100a. The place where the instruction input means 202 is provided is arbitrary, but it is preferable to provide the instruction input means 202 on the frame 201 from the viewpoint of facilitating the user to input the instruction during the measurement operation. On the other hand, the instruction recognition means 203 may be provided on the frame 201 or at another location.

When the instruction input means 202 is used as a sound collecting means such as a microphone and the instruction recognizing means 203 is configured to recognize the instruction content from the voice picked up by the sound collecting means, for example, the voice "imaging" is picked up. When this is done, the instruction recognizing means 203 recognizes the imaging instruction from the voice and gives an imaging instruction to the imaging means 101, and when the voice "save" is picked up, the instruction recognizing means 203 measures the value from the voice. It is possible to give an instruction to the measured value reading means 102 to store the measured value in the measured value storing means 100a by recognizing the storage instruction of. As a result, the user does not have to use his / her hand when inputting the instruction, and as described above, the direction of the imaging can be set so that the target measuring tool is imaged without using the hand. It is possible to perform imaging and storage of measured values without using any hands. Therefore, even if both hands are occupied due to the measurement operation by the target measurement tool, the user inputs an instruction to the measurement data collection device 200 by voice or the like to image the target measurement tool and read the measured value. be able to. In addition, although the case where the instruction is input by voice is described here as an example, the instruction may be input by blinking or other physical movement of the user other than voice.

The measured value reading means 102, the tool specific information storage means 103, the tool identification means 104, the reading method storage means 105, and the reading method specifying means 106 are different from the frame 201 even if they are provided in the frame 201 and integrally configured. It may be installed in the place of. When it is provided in another place, it may be arbitrarily decided whether to provide all in another place or a part in another place while considering the structural design of the frame 201 and the like.

[Third Embodiment]
FIG. 6 is a diagram showing a configuration example of the measurement data collecting device 300 according to the present embodiment. The measurement data collecting device 300 includes an imaging means 101, a measured value reading means 102, a tool specific information storage means 103, a tool identification means 104, a reading method storage means 105, a reading method specifying means 106, a frame 201, an instruction input means 202, and an instruction. The recognition means 203 and the display means 301 are provided. That is, the measurement data collection device 300 is the measurement data collection device 200 with the display means 301 added.

The display means 301 superimposes and displays the measured value read by the measured value reading means 102 on the scene in the visual field direction of the user wearing the frame 201. By providing the display means 301 on the frame 201, the measured value can be visually recognized as a numerical value even when an analog measuring tool is used. In addition, it contributes to the improvement of work efficiency of the user who does not know how to read the measured value from the scale or cannot read it smoothly. The effect can be obtained by providing the display means in a place other than the frame 201, but by providing the display means in the frame 201 as in the present embodiment, the display means can be quickly provided without losing the line of sight or moving the body during the measurement operation. Since the measured values can be confirmed, it contributes to further improvement of work efficiency.

The display means 301 that superimposes and displays the measured value read by the measured value reading means 102 on the view in the visual field direction of the user wearing the frame 201 is configured to realize so-called Augmented Reality (AR). That is, augmented reality is realized by adding and presenting additional information called measured values to the actual environment in which the measurement operation is performed. Specifically, for example, it can be realized by providing the display means 301 which is a transmissive display on the spectacle-shaped frame 201 as shown in FIG. 7, and can also be realized by a transmissive head-mounted display. The head-mounted display is a head-mounted frame 201 provided with display means 301. Although the transmissive head-mounted display does not allow you to directly see the outside when it is attached, the display shows the scene in the direction of the user's field of view, so by displaying the measured values on top of this, augmented reality can be achieved. It can be realized.

The measured value reading means 102, the tool specific information storage means 103, the tool identification means 104, the reading method storage means 105, and the reading method specifying means 106 are different from the frame 201 even if they are provided in the frame 201 and integrally configured. It may be installed in the place of. When it is provided in another place, it may be arbitrarily decided whether to provide all in another place or a part in another place while considering the structural design of the frame 201 and the like.
