Japanese Patent Publication No. 8-21154 Japanese Patent No. 2589807

  When collecting measurement data, analog measurement tools may cause the trouble of transferring the measured values to paper or inputting them to a personal computer, or mistakes at the time of posting, and both hands may be blocked during measurement. Since it is difficult to record the measured value while measuring, the measured value must be recorded every time the measurement is performed. On the other hand, with a digital measuring tool, collection of measurement data is relatively easy and almost no transfer errors occur, but it is more expensive than an analog measuring tool because a CPU, communication function, and the like are mounted. Also, the cable becomes an obstacle when transferring data by wired communication.

  An object of the present invention is to provide a measurement data collection device and a program that can easily collect measurement data by reading measurement values from measurement results regardless of whether the measurement tool is analog or digital.

Measurement value reading means. In the present invention, since the measurement value is read from the image obtained by imaging the target measurement tool, it is possible to easily collect measurement data regardless of whether the measurement tool is analog or digital, and the measurement tool has a communication function. There is no need. In addition, even a user who does not know how to read a measurement value with an analog measurement tool can collect measurement data.

  The measurement data collection device of the present invention includes a tool identification information storage unit that stores tool identification information for each type of measurement tool, an external image of the target measurement tool, and a tool identification information stored in the tool identification information storage unit. The tool specifying means for identifying the type of the target measurement tool by comparing the above, the reading method storage means for storing the measurement value reading method from the appearance image for each type of the measuring tool, and the measurement specified by the tool specifying means A reading method specifying unit that specifies a reading method of the measurement value corresponding to the type of the tool with reference to the reading method storage unit, and the reading method specifying unit is a reading method of the measuring value specified by the reading method specifying unit. Thus, the measurement value may be read from the appearance image of the target measurement tool. The tool identification information may be all or part of the appearance image of the measurement tool, or may be identification information that can be read directly or indirectly from the appearance image of the measurement tool. In the case of the identification information, the tool specifying means reads the identification information directly or indirectly from the appearance image of the target measuring tool and collates with the tool specifying information. By configuring in this way, it is possible to determine the type of the measurement tool from the appearance image and select the measurement value reading method according to the type, so that it is possible to read the measurement values for a plurality of types of measurement tools. Become.

  The tool specifying information storage means further stores tool specifying information for each individual measuring tool, the tool specifying means further specifies the target measuring tool individual, and corresponds to the measuring tool specified by the tool specifying means. It may further comprise reading control means for controlling to issue a predetermined warning and / or not to read the measurement value by the measurement value reading means.

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

  The imaging unit 101 images the appearance of the target measurement tool on which the measurement result is displayed. The imaging unit 101 is generally assumed to use a camera that captures a still image. However, since a still image only needs to be output in the end, for example, a still image is extracted from a moving image and output. A video camera or the like may be used. The target measurement tool is a measurement tool to be used for reading measurement values by the measurement data collection device 100, and any tool can be used as long as the measurement result can be visually recognized from the appearance. The measurement result is the measurement value itself in the case of a digital measurement tool, but in the case of an analog measurement tool, it is an object for reading the measurement value and is generally expressed by a scale or the like. The imaging of the appearance by the imaging unit 101 needs to be performed at least in the range and resolution necessary for reading the measurement result because the measurement result needs to be read from the appearance image. For example, when the target measuring tool is an analog caliper 10 as shown in FIG. 1, it is necessary to capture an image with a range and resolution at which the scale can be read at least about a portion surrounded by a dotted line.

  The measurement value reading unit 102 reads the measurement value from the appearance image of the target measurement tool imaged by the imaging unit 101. A method for reading a measurement value from an appearance image will be described by taking each measurement 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 vernier caliper 10 sandwiches an object for dimension measurement between the main scale 10a and a slider 10b provided to be slidable 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 that is swung on the main scale 10a every 1 mm and the vernier scale that is swung on the slider 10b every 1.95 mm.

  Specifically, the integer part of the measured value is read by grasping where the leftmost 0 scale of the vernier scale indicates the full scale scale. That is, if the leftmost 0 scale of the main scale is 0th 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, the 0 scale of the vernier scale points between the 16th main scale and the 17th main scale, so that the integer part can be read as 16 mm. Moreover, the figure below the decimal point of a measured value is read per 0.05 mm by grasping | ascertaining what number scale the vernier scale with which a full scale scale and a vernier scale become a straight line makes 0 scale 0th. In the example of FIG. 2, since it is in a straight line at the third vernier scale, 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 measurement value from the appearance image, the measurement value can be read by analyzing the image in the same manner. For example, first, an appearance image of the target measurement tool based on the position information of the scale of the main scale in the appearance of the measurement tool of the target measurement tool type prepared in advance or provided from others in the measurement value reading unit 102 To grasp the existence of the 0th scale scale. Subsequently, the measurement value is read from the appearance image based on the measurement value reading method of the measurement tool of the type of the target measurement tool prepared in advance or provided from others in the measurement value reading means 102. Specifically, the appearance of the 0th vernier scale is detected by scanning the appearance image around the main scale in the direction in which the number of scales increases while counting the number of scales from the grasped 0th scale scale. Then, the main scale indicated by the vernier scale is specified to be between the nth and n + 1th, and the integer part of the measured value is read as n. Here, when the main scale and the vernier scale are already aligned, 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 scales. If the part where the main scale and the vernier scale are in a straight line is detected, the number of the vernier scale in that part is specified, and if it is the mth, m is multiplied by 0.05. Read the decimal point of the measured value.

  FIG. 3A is a diagram showing an appearance of a micrometer 20 which is an example of an analog type micrometer, and FIG. 3B is a diagram excerpting a portion where a measurement result of the micrometer 20 is displayed. The micrometer 20 sandwiches an object for dimension measurement between the anvil 20a and the 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 that is swung to the sleeve 20c every 0.5 mm and the thimble scale that is swung to the thimble 20d every 0.01 mm.

  Specifically, first, the measurement value is read in units of 0.5 mm depending on how many scales are exposed with the 0 scale on the leftmost side of the sleeve scale as 0th. 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, depending on where the reference line 20e of the sleeve 20c points on the thimble scale, a value of 0 mm or more and less than 0.5 mm to be added to the value indicated on the sleeve scale is read. The reading is performed, for example, based on the scale from which the closest number is assigned to the scale from the thimble scale indicated by the reference line 20e. The thimble scale is numbered every 5 scales from the 0th scale to the 49th scale. Since the scale is swung every 0.01 mm, 0.01 times the number of each scale is an actual value. In the example of FIG. 3 (b), the scale number indicating the closest number from the thimble scale pointed to by the reference line 20e is 0, that is, the 0th scale, and the reference line 20e is the scale number from there. Indicates the first scale in the direction of increasing, so 0 + 1 = 1 as a whole corresponds to the first scale. Therefore, the value added to the value indicated 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 reference number 20e indicates the closest scale number from the thimble scale indicated by the reference line 20e, the reference number 20e indicates the second scale in the direction from which the scale number decreases. Then, 45-2 = 43, which corresponds to the 43rd scale as a whole. Therefore, the value added to the value indicated 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 measurement value from the appearance image, the measurement value can be read by analyzing the image in the same manner. For example, first, based on the position information of the 0 scale of the sleeve in the appearance of the measurement tool of the type of the target measurement tool, which is prepared in advance in the measurement value reading unit 102 or provided from others, from the appearance image of the target measurement tool Grasp the presence of the 0th sleeve scale. Subsequently, the measurement value is read from the appearance image based on the measurement value reading method of the measurement tool of the type of the target measurement tool prepared in advance or provided from others in the measurement value reading means 102. Specifically, the external image of the periphery of the sleeve scale centering on the reference line 20e is scanned in the direction in which the number of scales increases from the grasped 0th sleeve scale and the number of scales increases, and the end of the thimble Is detected, it is determined that the thimble scale exposed at that time is n-th, and n is multiplied by 0.5 to read the measured value in units of 0.5 mm. Also, the number m of the thimble scale shown closest to the thimble scale indicated by the reference line 20e is scanned and grasped, and the number of the scale is counted while counting the number of scales 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 number of the thimble scale pointed to by the detected reference line 20e is specified from the mth thimble scale, and if it is the second, m + 2 is multiplied by 0.01 and the measured value is measured 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 necessarily 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 one of the nearest scales can be adopted.

  FIG. 4A is a diagram showing an appearance of a digital caliper 30 that is an example of the digital caliper, and FIG. 4B is a diagram excerpting 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 measurement value from the appearance image, first, for example, the position information of the display unit 30a in the appearance of the measurement tool of the type of the target measurement tool prepared in advance in the measurement value reading unit 102 or provided from others is used. Based on the appearance image of the target measuring tool, the presence of the display unit 30a is grasped. Subsequently, the measurement value is read from the appearance image based on the measurement value reading method of the measurement tool of the type of the target measurement tool prepared in advance or provided from others in the measurement value reading means 102. Specifically, each digit number displayed on the display unit 30a of the target measurement tool is compared with the shape of the numbers 0 to 9 unique to the display unit 30a of the measurement tool type of the target measurement tool. The measured value is read by specifying the number of each digit displayed on the display unit 30a of the tool.

  Even if the appearance imaging by the imaging unit 101 is not performed in the range and resolution necessary for reading the measurement result, the measurement value reading unit 102 may be configured to issue a warning that reading is impossible. Good. In addition, if it is configured to automatically retry imaging when reading is not possible, scanning is performed when reading is possible, and a warning is issued if reading is not possible after a predetermined number of retries. You may comprise. Whether or not reading is possible is determined by analyzing the captured image and, for example, if there is no pixel equal to or greater than the threshold value between the graduation lines.

  When there is only one type of target measurement tool, there is no need to specify the type of measurement tool or to specify the method of reading the measurement value according to the type, and therefore the measurement value reading means 102 is provided for the measurement tool of that type prepared in advance. Based on the measurement value reading method, the measurement value is read from the measurement result displayed in the appearance image.

  On the other hand, when there are a plurality of types of target measurement tools, it is necessary to specify the type of the measurement tool and to specify the reading method of the measurement value according to the type. 103, a tool specifying unit 104, a reading method storage unit 105, and a reading method specifying unit 106 are further provided.

  The tool specifying information storage unit 103 stores tool specifying information for each type of measuring tool. The tool specifying information is identification information that can be read directly or indirectly from, for example, the appearance image of the measurement tool or the appearance image of the measurement tool. The identification information is, for example, the name, model number, and manufacturing number of the type of measurement tool. When the appearance image of the measurement tool is stored, the appearance image to be stored may be an entire image of the measurement tool or a characteristic partial image that can specify the measurement tool. Further, a two-dimensional image or a three-dimensional shape model may be used. While the two-dimensional image can be easily prepared, when the appearance of the target measurement tool is imaged, if the image is captured at an angle significantly different from the imaging angle of the appearance image stored in advance in the tool specifying information storage unit 103, the tool specifying unit 104 There is a possibility that it cannot be collated well at the time of image collation. On the other hand, although a three-dimensional shape model is not easy to prepare, since it is possible to contrast appearance images at a plurality of angles for one type of measurement tool at the time of collation by the tool specifying means 104, a collation error is caused. And reduce errors.

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

  The reading method storage unit 105 stores a measurement value reading method from an appearance image for each type of measurement tool. The information stored as the measurement value reading method includes, for example, a method of reading the measurement value from the position of the display portion of the measurement result on the appearance of the measurement tool or the measurement result. A specific example of the method of reading the measurement value from the measurement result is as described above with reference to FIGS. Then, the reading method specifying unit 106 specifies the measurement value reading method corresponding to the type of the measurement tool specified by the tool specifying unit 104 with reference to the reading method storage unit 105.

  Finally, the measurement value reading unit 102 reads the measurement value from the appearance image of the target measurement tool by the measurement value reading method specified by the reading method specifying unit 106. The read measurement value is stored in the measurement value storage means 100a, for example. 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 a temporary storage means such as a semiconductor memory is used if necessary. It doesn't matter.

  By configuring as described above, the type of the measurement tool can be specified from the appearance image, and the measurement value reading method according to the specified type can be selected, so that the measurement values can be read for a plurality of types of measurement tools. Is possible. Further, even when the number of types of measuring tools to be used increases, it is only necessary to add information on newly added measuring tools to the tool specifying information storage means 103 and the reading method storage means 105 without changing the overall configuration of the apparatus. Can respond.

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

  Further, the tool specifying information storage means 103 further stores tool specifying information for each individual measuring tool, the tool specifying means 104 further specifies the target measuring tool individual, and the measurement specified by the tool specifying means 104. Depending on the individual tool, the reading means 107 may be further configured to control the display means 100b or the like to issue a predetermined warning and / or not to read the measurement value by the measurement value reading means 102. Calibration of the measuring tool is usually performed by the measuring tool management department (in charge) and is not performed every time the operator uses it. There is a possibility of measuring with an expired measuring tool. Therefore, this configuration enables safety measures such as checking whether the specified measuring tool has been calibrated and warning it, or not reading the measured value if the calibration has expired. Management man-hours can also be reduced.

[Second Embodiment]
FIG. 5 is a diagram illustrating a configuration example of the measurement data collection device 200 according to the present embodiment. The measurement data collection device 200 includes an imaging unit 101, a measurement value reading unit 102, a tool identification information storage unit 103, a tool identification unit 104, a reading method storage unit 105, a reading method identification unit 106, a frame 201, an instruction input unit 202, and Instruction recognition means 203 is provided. That is, the measurement data collection device 200 is obtained by adding a frame 201, an instruction input unit 202, and an instruction recognition unit 203 to the measurement data collection device 100.

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

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

  When the instruction input unit 202 is a sound collection unit such as a microphone, and the instruction recognition unit 203 is configured to recognize the instruction content from the sound collected by the sound collection unit, for example, a voice “imaging” is collected. Then, the instruction recognizing unit 203 recognizes the imaging instruction from the voice and gives an imaging instruction to the imaging unit 101. When the voice of “save” is collected, the instruction recognizing unit 203 measures the measured value from the voice. Can be given to the measured value reading means 102 to store the measured value in the measured value storage means 100a. This eliminates the need for the user to use his / her hand when inputting an instruction, and as described above, the direction of imaging can be set to the direction in which the target measuring tool is imaged without using the hand. It is possible to execute imaging and storage of measured values without using any hands. Therefore, even if both hands are occupied for the measurement operation by the target measurement tool, the user inputs an instruction by voice or the like to the measurement data collection device 200 to image the target measurement tool and read the measurement value. be able to. Here, the case where the instruction is input by voice has been described as an example. However, the instruction may be input by blinking or other movements of the user's body other than the voice.

  The measurement value reading means 102, the tool specifying information storage means 103, the tool specifying means 104, the reading method storage means 105, and the reading method specifying means 106 are provided on the frame 201 and are configured integrally with the frame 201. You may provide in the place. When providing in another place, whether to provide all in another place or a part in another place may be arbitrarily determined in consideration of the structural design of the frame 201 and the like.

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. Moreover, it contributes to the improvement of the working 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 also be obtained by providing the display means at a place other than the frame 201. However, by providing the display means on the frame 201 as in the present embodiment, it is possible to quickly remove the line of sight or move the body during the measurement operation. Therefore, it is possible to confirm the measured value, which contributes to further improvement in work efficiency.

  The display unit 301 that displays the measurement value read by the measurement value reading unit 102 on the scene in the direction of the field of view of the user wearing the frame 201 is configured to realize a so-called augmented reality (AR). That is, augmented reality is realized in the form of adding additional information called measurement values to the actual environment where the measurement operation is performed. Specifically, for example, it can be realized by providing a display unit 301 which is a transmissive display on a 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 cannot be seen directly when worn, it displays the scene in the user's field of view on the display, so displaying augmented reality by overlaying the measured values on this display Can be realized.

FIG. 8 is a diagram illustrating a configuration example of the measurement data collection device 400 according to the present embodiment. The measurement data collection device 400 is configured such that, in the measurement data collection device 300, each unit provided in the frame 201 and other units can communicate wirelessly. Hereinafter, a set of other means other than the means provided in the frame 201 is referred to as a data collection unit 400a. The data collection unit 400a can be configured, for example, by applying a program in which processing contents of each means are described to a mobile terminal such as a smartphone or a personal computer. Each of the frame 201 and the data collection unit 400a includes a wireless transmission / reception unit 400b. The wireless communication method of the wireless transmission / reception unit 400b is arbitrary.
