Description

  The present invention relates to an image measuring apparatus and a computer program for simply measuring a dimension or the like of a measurement object based on captured image data.

  Conventionally, as a device for measuring the shape of a measurement object, the measurement object is irradiated with light, and the transmitted light or reflected light of the irradiated light is received by a light receiving lens, CCD (Charge Coupled Device), CMOS (Complementary Metal-Oxide Semiconductor) There is an image measurement device that obtains an image by forming an image on an image pickup device such as) and measures the shape of a measurement object by computer processing the obtained image.

  The image showing the measurement object can be made into a very accurate similar shape to the measurement object by the light receiving lens. By calibrating the dimensions on the image with the magnification of the light receiving lens, the dimensions on the image can be accurately associated with the dimensions of the actual measurement object. Therefore, by accurately specifying the shape of the measurement object on the image, the accurate shape of the actual measurement object can be measured. The shape of the measurement object on the image is specified by detecting a boundary part (hereinafter referred to as an edge part) between the measurement object and the background image. The edge portion is a portion where the luminance value change between the pixel of the measurement object and the pixel of the background image is intense, and therefore, from a fraction of one pixel to several tens based on the information on the luminance value change of the pixel near the edge. Edge portions are detected with a precision of 1 /.

  FIG. 20 is an explanatory diagram of areas and the like that are specified when measuring a conventional measurement object. FIG. 20A shows an area specified when measuring the width of a rectangular measurement object, and FIG. 20B shows an area specified when measuring the diameter of a circular measurement object. When measuring the width of the measurement object, as shown in FIG. 20A, the operator designates a rectangular area b for detecting an edge portion (straight line portion a) at one end of both ends of the horizontal width. Then, the cursor is moved by the mouse or the like along the scan line d in order to detect the point c at the other end. In the rectangular area b, based on the change in the luminance value of the pixel, for example, a portion (between pixels) where the luminance difference between adjacent pixels is larger than a predetermined value is detected as the straight line portion a. Further, a point where the luminance difference between adjacent pixels on the scan line d is larger than a predetermined value is detected as a point c. The distance from the detected point c to the straight line portion a can be acquired as the width dimension.

  When measuring the diameter of a circular measuring object, the operator designates a circular region f including a circle e as shown in FIG. A circle e is detected based on the change in luminance value of the pixels in the circle region f, and the diameter of the detected circle e is calculated.

  In order to measure the dimension of the shape of the measurement object as described above, first, it is necessary to detect necessary edge portions such as straight lines and points in the case of width according to the shape of the portion to be measured. . In order to detect an edge portion, an area including an edge portion, for example, a rectangular region including a straight line portion when detecting as a straight portion, or a straight line portion (scan line) when detecting as a point is appropriately specified. There is a need to. The area must be specified using various mouse operations such as start point click, end point click, and drag. Therefore, in the measurement of the measurement object on the image, there is a problem that it is not possible to intuitively operate to measure the measurement object that is a substance using a measuring instrument.

In order to detect an edge by a simple operation, for example, in Patent Document 1, the coordinates of an edge point that is closest to a point designated by a mouse on an image are obtained, and an edge position detection region centered on the obtained edge point An image measuring apparatus for setting the value is disclosed. In Patent Document 1, an operator can set an area including an edge portion by simply pointing one point with a mouse, and can easily detect the edge portion.

  In the first invention and the seventh invention, an image showing a measurement object and an image showing a measuring instrument composed of a measurement part and a main part are displayed, and an image showing at least one measurement part is displayed as an image showing the main part. An instruction to move in the longitudinal direction is received. Whether the coordinate value on the screen of the image data corresponding to the image indicating the detection unit in the measurement unit matches the coordinate value on the screen of the image data corresponding to the image indicating the edge of the measurement target portion of the measurement target Determine whether. If they match, an instruction to the effect that it is the measurement position of the measurement object is received, and an actual measurement value of the measurement target part is calculated based on the coordinate value on the screen of the measurement position at which the instruction is received. Therefore, by simply moving the image showing the detection unit on the screen so that it touches the image showing the edge of the measurement object, the measurement object can be measured by an intuitive operation that actually measures the dimensions of the measurement object using a measuring instrument.

It is possible to measure the measurement object with the same feeling as when measuring the dimensions of the measurement object with an actual measuring instrument.

  In the fourth invention and the tenth invention, an instruction to set any one side in the longitudinal direction of the main body portion as an image showing the detection portion among images showing the measurement portion is accepted. On the screen, each of the two measurement units can be set as two detection units, that is, in any one of the longitudinal directions of the main body unit. Therefore, by setting one of the two measurement units as a detection unit, when the detection units face each other, when facing in opposite directions, both of them are facing the same direction (left and right), the four types of variations Can be set. Therefore, by appropriately setting according to the shape of the measurement object, even a measurement object portion that cannot be measured by a real measuring instrument can be reliably measured.

  In 5th invention and 11th invention, by receiving the instruction | indication which changes the length of the extending | stretching direction of the image which shows a measuring part, or the instruction | indication which changes the position of an extending | stretching direction, both measuring parts are match | combined with the shape of a measurement object part. The length can be changed so that it is easier to visually confirm whether or not the detection unit is in contact with the edge. In addition, by making one measurement unit longer than the other measurement unit, for example, when measuring the step of each step in a stepped shape, each detection unit of the two measurement units directly on the image showing each step By adjusting the length of the measurement unit so as to touch, the step for each step can be accurately measured. Therefore, even if the shape is difficult to measure with a real measuring instrument, it can be directly and accurately measured.

  In the sixth invention and the twelfth invention, by displaying the calculated actual measurement value on the image showing the main body, the measuring instrument is displayed on the screen in the same manner as when measuring the dimensions of the actual measuring object with the measuring instrument. The measured distance can be immediately grasped while measuring the measurement object using the image shown.

  According to the above configuration, just by operating the image indicating the detection unit of the measuring instrument so as to touch the image indicating the edge of the measuring object, the dimension of the measuring object is measured on the image so as to be measured by the actual measuring instrument. It is possible to provide an image measurement device and a computer program that can be easily measured by an intuitive operation.

First, a ring-shaped epi-illumination device 22 that illuminates the measurement object 20 on the stage 21 from above is installed in the light receiving lens unit 23. The light irradiated by the epi-illumination device 22 is reflected by the surface of the measurement object 20 and returns to the light receiving lens unit 23. Thereby, the unevenness | corrugation of the surface of the measurement target object 20, a pattern, etc. can be imaged.

  A transmission illumination device 24 that illuminates the measurement target 20 from below is installed below the stage 21. The transmitted illumination device 24 includes at least a light source 241, a reflection mechanism 242, and a lens 243. The light emitted from the light source 241 is reflected by the reflection mechanism 242 toward the stage 21, and the lens 243 reflects the stage 21. To be converted into parallel light in a direction substantially perpendicular to each other. Thereby, only the light of the position where the measuring object 20 does not exist can be transmitted and imaged.

  The light receiving lens unit 23 includes at least a light receiving lens 231, a beam splitter 232, a high magnification side imaging lens unit 233, and a low magnification side imaging lens unit 236.

A lens 238 is used. The beam splitter 232 is a prism that branches light from the light receiving lens 231 in two directions. For example, a cube type or a plate type can be used. Compared with the plate type, the cube type beam splitter is preferable because the light passing through the beam splitter is not refracted, the optical axis is not shifted, and alignment adjustment of the branch angle is easy.

  In FIG. 1, the light emitted from the epi-illumination device 22 is reflected by the measurement object 20 and the light emitted from the transmission illumination device 24 and transmitted through the measurement object 20 is divided into the high-magnification imaging lens unit 233 and the low magnification. An example of guiding to the side imaging lens unit 236 is shown. The light in two directions branched by the beam splitter 232 is guided to both the low magnification side imaging lens unit 236 and the high magnification side imaging lens unit 233.

  The high-magnification side imaging device 25 causes the light guided to the high-magnification side imaging lens unit 233 to be imaged by an imaging element 251 such as a CCD or CMOS, and transmits the image to the control unit 3 as high-magnification image data. Similarly, the low-magnification side imaging device 26 causes the light guided to the low-magnification side imaging lens unit 236 to be imaged by an imaging element 261 such as a CCD or CMOS, and transmits it to the control unit 3 as low-magnification image data. With the above-described configuration of the two-branch optical system including the light receiving lens 231 and the beam splitter 232, high-magnification image data and low-magnification image data can be acquired simultaneously without mechanically switching the optical system. Both image data can be electronically switched and displayed on one screen, or can be displayed separately on two screens simultaneously.

  FIG. 2 is a block diagram showing the configuration of the control unit 3 of the image measurement apparatus 1 according to Embodiment 1 of the present invention.

  The CPU 33 also functions as a measurement target presence / absence determination unit 338 and a position acquisition unit 339 that acquires the coordinate value of the measurement position of the measurement target 20 based on the determination by the measurement target presence / absence determination unit 338. The CPU 33 also serves as a setting instruction receiving unit 341 that receives an instruction to set the detection unit to one of the measurement units of the measuring instrument and an expansion / contraction instruction receiving unit 342 that receives an instruction to change the length of the measuring unit of the measuring instrument.

Here, the alignment means that the coordinate position on the display screen is matched between the incident image and the transmission image. By storing the two types of image data that have been aligned, it is possible to select appropriate image data in accordance with the edge detection region for which the designation has been received. When measuring the shape of the outer shape of the measuring object 20, optimal transmission image data can be used to measure the dimension of the contour line portion indicating the outer shape. Further, the shape formed as the irregularities on the surface of the measurement object 20 can also be measured by processing the incident image data in the same manner as the transmission image data.

  The display unit 332 displays the transmission image data or the incident image data received by the communication unit 35 as a transmission image or an incident image on the display device 27 such as an LCD or an organic EL display. FIG. 3 is an exemplary diagram illustrating an example of a screen on which the display unit 332 displays the image data of the measurement target 20 and the measuring instrument 28. FIG. 3A shows a display state before measurement, and FIG. 3B shows a display state during measurement. FIG. 4 is a schematic diagram for explaining an operation state for measurement.

Is moved in the longitudinal direction. Moreover, without distinguishing the measurement part 282 by rotation of a mouse wheel, when the mouse wheel is turned to the back, for example, both measurement parts 282 may approach, and when it turns to the front, it may be made to go away.

  Further, as another movement method of the entire measuring instrument 28 and the measuring unit 282, when an image such as a caliper is displayed as the measuring instrument 28 on the display device 27, an image showing the measuring instrument 28, the measuring unit 282, etc. is displayed as a mouse. When the mouse wheel is rotated, the image showing one measurement unit 282 moves so as to approach the image showing the edge 285, and when the mouse wheel is further rotated, The movement of the image may be controlled so that the image showing the other measurement unit 282 approaches the image showing the edge 285 while the image showing the measurement unit 282 is in contact with the image showing the edge 285.

  As described above, the image showing the measurement unit 282 is moved in the longitudinal direction of the image showing the main body unit 281 by the mouse operation on the screen so that the image showing the detection unit 283 is in contact with the image showing the edge 285. Thus, the measurement object 20 can be easily measured by an intuitive operation on the image so that the dimension of the actual measurement object is measured by the measuring instrument.

  In order to simplify the operation of bringing the detection unit 283 into contact with the edge 285, in the first embodiment, the image data of the detection unit 283 is transferred to one side in the longitudinal direction of the main body 281 in the measurement unit 282. The movement instruction receiving means 333 uses the image indicating the detection unit 283 as the image data including the detection unit 283, and the image indicating the detection unit 283 indicates the edge 285 of the measurement target portion. An instruction to move the image by a predetermined distance in a direction approaching the image is received.

  In response to an instruction to move a predetermined distance, the measurement target presence / absence determining unit 338 determines whether an edge 285 exists between the start point and the end point where the image indicating the detection unit 283 moves by a predetermined distance. That is, when the edge 285 exists, it can be determined that the image showing the detection unit 283 moves beyond the image showing the edge 285, and when the edge 285 does not exist, the image showing the detection unit 283 becomes an edge. It can be determined that the image does not move beyond the image indicating H.285. When the measurement target presence / absence determination unit 338 determines that the edge 285 of the measurement target portion exists, the coordinate value on the screen of the edge 285 is acquired as the coordinate value of the measurement position based on the image data of the image indicating the edge 285. .

  When the measurement target existence determination unit 338 determines that the edge 285 of the measurement target portion does not exist, the end point of the movement of the detection unit 283 is set as a new start point. The predetermined distance may be a distance dragged with a mouse or the like, or an instruction to move a predetermined distance by dragging may be accepted regardless of the distance dragged with the mouse or the like.

  FIGS. 5 to 7 are exemplary diagrams showing each state in the process of measuring the measurement target 20 using the measuring instrument 28 on the screen. 5A shows a state in which the measuring instrument 28 is brought close to the measurement object 20, and FIG. 5B shows a state in which the longitudinal direction of the main body 281 is aligned with the dimension direction of the measurement target portion 284. FIG. ) Shows a state in which the two measurement units 282 are expanded wider than the measurement target portion 284, and FIG. 6D shows a state in which the detection unit 283 of the measurement unit 282R is in contact with the edge 285. FIG. 7 shows a state in which the detection unit 283 of the measurement unit 282L is in contact with the edge 285, and in FIG. 7F, the detection unit 283 of the two measurement units 282 is in contact with the two edges 285 of the measurement target portion 284. Each state is shown. FIG. 8 is an explanatory diagram of restrictions on the rotation direction and the movement distance for the measuring unit 282 and the measuring instrument 28 as a whole. FIG. 8A shows the restriction on the movement distance, and FIG. 8B shows the restriction on the rotation direction.

  5A to 7F, one measurement unit 282L is fixed to the main body unit 281, and the detection units 283 of the two measurement units 282 face each other with respect to the longitudinal direction of the main body unit 281. Exists on the side. As shown in FIG. 5A, the measuring instrument 28 is moved closer to the measuring object 20 by moving the entire measuring instrument 28. The detection unit 283 of the measurement unit 282L is moved so as not to overlap the measurement target portion 284. As shown in FIG. 5B, the longitudinal direction of the main body 281 is aligned with the dimension direction of the measurement target portion 284 by rotating the entire measuring instrument 28 on the screen. The detection unit 283 of the measurement unit 282L faces the measurement target portion 284 without overlapping.

  As shown in FIG. 6C, the measurement unit 282R is expanded so that the interval between the two measurement units 282 is wider than the dimension of the measurement target portion 284. As shown in FIGS. 6D and 8A, for example, when the mouse wheel is rotated, an image showing the measurement unit 282R in the longitudinal direction of the main body 281 and the detection unit 283 is displayed on the screen. The movement instruction receiving means 333 receives an instruction to move the distance in a direction approaching and facing the image indicating the edge 285. In response to the instruction received by the movement instruction receiving unit 333, the measurement target presence / absence determination unit 338 determines whether there is an image indicating the edge 285 between the start point and the end point where the image indicating the detection unit 283 moves by a predetermined distance. Judging.

  When the measurement target existence determination unit 338 determines that an image indicating the edge 285 exists, that is, when the detection unit 283 determines to move beyond the edge 285, the position acquisition unit 339 corresponds to the image indicating the edge 285. The coordinate value of the data is acquired as the coordinate value of the measurement position. On the screen, as shown in FIG. 6D, an image showing the measurement unit 282R is displayed so that the detection unit 283 moves until it contacts the edge 285. After the detection unit 283 is in contact with the edge 285, the position of the measurement unit 282R is temporarily prevented from moving until, for example, the detection unit 283 is in contact with the other edge 285.

  When the measurement target presence / absence determination unit 338 determines that there is no image indicating the edge 285, that is, the detection unit 283 does not move beyond the edge 285, the position acquisition unit 339 sets the end point as a new start point. On the screen, an image showing the measurement unit 282 is displayed so as to move a predetermined distance for which the instruction has been accepted. The detection unit 283 can be provided on both sides of the measurement unit 282. However, when the detection unit 283 is provided on both sides, it is necessary to determine which detection unit 283 is used for detection. Since the detection unit 283 is provided only on one side of the measurement unit 282, it can be easily grasped that the detection unit 283 contacts the edge 285.

  As shown in FIG. 7E, for example, by rotating the mouse wheel, the image of the main body 281 and the measurement unit 282L in the longitudinal direction of the main body 281 and the detection unit 283 is displayed on the screen. The movement instruction receiving means 333 receives an instruction to move a predetermined distance in a direction facing and approaching the image showing the edge 285. In response to the instruction received by the movement instruction receiving unit 333, the measurement target presence / absence determination unit 338 determines whether there is an image indicating the edge 285 between the start point and the end point where the image indicating the detection unit 283 moves by a predetermined distance. Judging.

  When the measurement target existence determination unit 338 determines that an image indicating the edge 285 exists, the position acquisition unit 339 acquires the coordinate value of the image data corresponding to the image indicating the edge 285 as the coordinate value of the measurement position. On the screen, as shown in FIG. 7F, an image showing the measurement unit 282 is displayed so that the detection unit 283 moves until it contacts the edge 285. Note that if the measurement target presence / absence determination unit 338 determines that there is no image indicating the edge 285, the position acquisition unit 339 sets the end point as a new start point. On the screen, an image showing the measurement unit 282 is displayed so as to move a predetermined distance for which an instruction has been received without limiting the movement distance.

  As shown in FIG. 7F, when the detection units 283 of the two measurement units 282 are in contact with the two edges 285 of the measurement target portion 284, the position acquisition unit 339 displays the edge 285 acquired as the coordinate value of the measurement position. Based on these coordinate values, the actual measurement value calculation means 336 calculates the actual measurement value of the measurement target portion 284. Specifically, the actual measurement value of the measurement target portion 284 is calculated by converting the measurement value on the screen by the scale magnification and the magnification of the light receiving lens. The actual measurement value is displayed on an image showing the main body 281. The actual measurement value may be displayed on a screen other than the main body 281, or the actual measurement value data may be input to a file and printed out.

  5 (a) and 5 (b), when the entire measuring instrument 28 is moved, for example, when the entire measuring instrument 28 is rotated as shown in FIG. 8 (b), for example, FIG. 6 (d) and FIG. Similarly to the case where the measurement unit 282 is moved in 7 (e), the measurement unit 282 may be moved only to a position where the detection unit 283 is in contact with the edge 285. The coordinate value can be obtained as the measurement position by making the detection unit 283 contact the edge 285 without making unnecessary movement beyond the contact position.

  The coordinate values on the screen of all the edges 285 are calculated in advance based on the image data, and the range in which the detection unit 283 can move is determined based on the calculated coordinate values of the edges 285 on the screen. . And when the movement instruction | indication of the detection part 283 is received, the method of determining whether it is a movement within the defined range and restricting the movable range of the detection part 283 may be used.

  FIG. 9 is an explanatory diagram of movement direction restrictions when measuring a rectangular measurement object 20. As shown in FIG. 9, when measuring the width of the rectangular measurement object 20, it is difficult to perfectly match the dimension direction (width direction) of the measurement target portion 284 with the longitudinal direction of the main body 281. In the above, when one point of the measurement target 20 is in contact with the tip or the root of the detection unit 283, a correct value cannot be measured by measuring obliquely. In order to measure a correct value, for example, when the measurement object 20 is in contact with the tip of the detection unit 283, an instruction to move the measurement unit 282 or the measuring device 28 next without obtaining the coordinate value of the measurement position Is received, the measuring instrument 28 is rotated so that the detection unit 283 follows the straight line portions at both ends of the measurement target portion 284.

  Note that when measuring the measurement object 20, the measurement object 20 is not limited to linearly moving and rotating as described above, and the measurement object 20 may be linearly moved and rotated. . Further, the measuring instrument 28 and / or the measurement object 20 may be enlarged or reduced on the screen, and a method that makes it easy to bring the image showing the detection unit 283 into contact with the image showing the edge 285 is easy to measure. can do.

  In the first embodiment, as described above, the image showing the measurement unit 282 has the detection unit 283 on one side in the longitudinal direction of the main body unit 281. The setting instruction receiving unit 341 receives an instruction to set one side of the measuring unit 282 as the detecting unit 283. FIG. 10 is an exemplary diagram for explaining a variation on the side where each detection unit 283 exists in the longitudinal direction of the main body 281 in the two measurement units 282 on the screen. 10A to 10D are all fixed to the main body 281. In the two measurement units 282, each detection unit 283 can be set in any one of the longitudinal directions of the main body unit 281. As shown in FIG. 10 (a), the detection units 283 and 283 can be set to face each other, or can be set to face in opposite directions as shown in FIG. 10 (b). Also, as shown in FIGS. 10C and 10D, both may be set to face the same direction on either the left or right. The arrows shown on the measurement unit 282R in FIGS. 10A to 10D indicate the forward direction in which the mouse wheel is moved to the back, for example. The arrows shown on the measurement unit 282L in FIGS. 10A to 10D are fixed so that the measurement unit 282R is in contact with the edge 285 of the measurement target portion 284, as shown in FIGS. The direction in which the measurement unit 282L is moved to bring the measurement unit 282L into contact with the other edge 285 is shown.

  FIG. 11 is an illustration of measurement processing by the measurement unit 282 when the detection unit 283 is set to FIG. FIG. 11A shows an example of measuring the outer diameter of a circle, and FIG. 11B shows an example of measuring the diameter of a circular hole. The measuring instrument 28 having measuring units 282 and 282 that are present inside so that the detecting unit 283 faces each other has a circular shape as shown in FIG. 11B as well as the outer diameter of the circle as shown in FIG. The diameter of the hole can be measured.

  FIG. 12 is an exemplary diagram of a measurement process performed by the measurement unit 282 when the detection unit 283 is set to FIG. The measuring instrument 28 having the measuring unit 282 in which the detecting unit 283 exists in the opposite direction can measure the distance between two circles as shown in FIG.

  FIG. 13 is an exemplary diagram of a measurement process performed by the measurement unit 282 when the detection unit 283 is set to FIG. A measuring instrument 28 having a measuring unit 282 in which both detection units 283 are set on the left side can measure the distance between a large circle as shown in FIG. 13 and a small circle inside.

  In the first embodiment, the expansion / contraction instruction receiving unit 342 receives an instruction to change the length of the measuring unit 282 in the extending direction. FIG. 14 is an exemplary diagram illustrating a state where the length of the measurement unit 282 is changed. FIG. 14A is an exemplary diagram for explaining a method of changing the length by changing the entire length of the measuring unit 282L and changing the position of the measuring unit 282R from the main body 281. FIG. 14B is an exemplary diagram illustrating a state in which the length of the measuring unit 282L is changed by changing the position of the measuring unit 282L from the main body 281 to change the entire length of the measuring unit 282R. FIG. 14C illustrates an example in which the length is changed by changing the position of the measuring unit 282L from the main body 281 and the length is changed by changing the position of the measuring unit 282R from the main body 281. FIG.

  As shown in FIG. 14A, for the fixed measurement unit 282L, for example, when the measurement unit 282L is selected by a mouse operation, a rectangular region g indicating that editing is in progress is displayed. Further, the size of the rectangular region g can be changed by dragging the peripheral portion of the rectangular region g with a mouse operation, and the entire length of the measuring unit 282L can be changed. For the movable measuring unit 282R, for example, when the measuring unit 282R is selected by a mouse operation, a rectangular area h indicating that editing is in progress is displayed. Furthermore, by dragging the internal area of the rectangular area h by a mouse operation, the length can be changed by changing the position of the rectangular area h, that is, the position of the measuring section 282R from the main body section 281. FIG. 14B shows the result of changing the position of the measuring unit 282L from the main body 281 and changing the overall length of the measuring unit 282R. FIG. 14C shows a result of changing the lengths of the measuring units 282L and 282R by changing the positions of the measuring units 282L and 282R from the main body 281.

  FIG. 15 is an exemplary diagram of measurement processing by the measurement unit 282 when only the movable measurement unit 282R is changed in position. As shown in FIG. 15, a shape having a stepped step, for example, by a measuring unit 282R in which the position of the movable measuring unit 282R is changed from the main body 281 without changing the position of the fixed measuring unit 282L. Even so, the level difference can be measured by moving so that the detection units 283 of the two measurement units 282 are in direct contact with each other. In addition, by changing the length of both measurement units 282 in accordance with the shape of the measurement target portion 284, an image in which the detection unit 283 is in contact with the edge 285 can be easily seen and measured. Therefore, it is possible to directly and simply measure a shape that is difficult to measure with a real measuring instrument.

  Next, the operation of the image measuring apparatus 1 having the above-described configuration will be described in detail based on a flowchart. FIG. 16 is a flowchart showing a processing procedure of the CPU 33 of the control unit 3 of the image measuring device 1 according to Embodiment 1 of the present invention.

  As shown in FIG. 16, the CPU 33 of the control unit 3 displays any image data from the transmission image data or the incident image data of the measurement object 20 stored in the storage device 34 and the image data of the measuring instrument 28. The information is displayed on the device 27 (step S1601).

  As shown in FIG. 5A, the CPU 33 accepts an instruction to move the image showing the measuring instrument 28 to approach the image showing the measurement object 20, and displays the image according to the accepted instruction (step S1602). As shown in FIGS. 5B and 6C, the CPU 33 rotates the image showing the measuring instrument 28 to align the longitudinal direction of the main body 281 with the dimension direction of the measurement target portion 284 (step S1603). The measurement unit 282R is widened so that the interval between the two measurement units 282 is wider than the dimension of the measurement target portion 284.

  As shown in FIG. 6D, the CPU 33 displays an image showing the measurement unit 282R (movable measurement unit) on the displayed image as an image showing the detection unit 283 in the longitudinal direction of the image showing the main body unit 281. An instruction to move a predetermined distance in a direction approaching and facing the image indicating the edge 285 of the measurement target portion is received (step S1604). Specifically, for example, the measurement unit 282R is dragged in the direction of the edge 285, and the distance between the start point and the end point of the drag is received as a predetermined distance.

  In accordance with the received instruction, the CPU 33 moves and displays an image indicating the detection unit 283 by a predetermined distance. The CPU 33 determines whether or not there is an image showing the edge 285 between the start point where the image showing the detection unit 283 starts moving a predetermined distance and the end point where the movement is finished (step S1605).

  When the CPU 33 determines that there is no image indicating the edge 285 (step S1605: NO), the CPU 33 sets the end point where the image indicating the detection unit 283 has moved a predetermined distance as a new start point (step S1606), and performs processing. Returning to step 1604, the above-described processing is repeated.

  When the CPU 33 determines that there is an image indicating the edge 285 (step S1605: YES), the CPU 33 obtains a coordinate value based on the image data corresponding to the image indicating the edge 285, and acquires it as the coordinate value of the measurement position. (Step S1607). The measurement unit 282R is temporarily fixed at a position where the detection unit 283 contacts the edge 285.

  The CPU 33 repeats the above-described processing of steps S1604 to S1607 for the fixed measuring unit 282L. That is, as shown in FIG. 7E, an image showing the measurement unit 282L fixed to the main body 281 on the displayed image is an image showing the detection unit 283 in the longitudinal direction of the image showing the main body 281. Receives an instruction to move a predetermined distance in a direction facing and approaching the image showing the edge 285 of the measurement target portion (step S1604). Specifically, for example, by pressing the mouse button on the measurement unit 282L, dragging the mouse button toward the edge 285 in the pressed state, and releasing the pressed button, the position where the button is pressed and the position where the button is released. Is accepted as a predetermined distance.

  In accordance with the received instruction, the CPU 33 moves and displays an image indicating the detection unit 283 by a predetermined distance. The CPU 33 determines whether or not there is an image showing the edge 285 between the start point where the image showing the detection unit 283 starts moving a predetermined distance and the end point where the movement is finished (step S1605).

  When the CPU 33 determines that there is no image indicating the edge 285 (step S1605: NO), the CPU 33 sets the end point where the image indicating the detection unit 283 moves by a predetermined distance as a new start point (step S1606), and performs processing. Returning to step 1604, the above-described processing is repeated.

  When the CPU 33 determines that there is an image indicating the edge 285 (step S1605: YES), the CPU 33 obtains a coordinate value based on the image data corresponding to the image indicating the edge 285, and acquires it as the coordinate value of the measurement position. (Step S1607). The measurement unit 282L is temporarily fixed at a position where the detection unit 283 contacts the edge 285.

  The CPU 33 calculates an actual measurement value of the measurement target portion 284 based on the coordinate value of the measurement position acquired by the movable and fixed measurement units, that is, the coordinate value on the screen of the edge (step S1608).

  As described above, according to the first embodiment, the image indicating the detection unit is moved to the measurement target by moving the image indicating the detection unit several times in the direction of the image indicating the edge of the measurement target. Even if you do not touch the image that shows the edge of the object accurately, you can automatically touch it, and the intuitive dimensions on the screen are the same as when measuring the dimensions of the measurement object with an actual measuring instrument. The measurement object can be easily measured by a typical operation.

(Embodiment 2)

As shown in FIG. 17, the hardware configuration of the control unit 3 of the image measurement apparatus 1 according to the second embodiment is the same as that of the first embodiment. Is omitted.

  However, in the second embodiment, the CPU 33 of the control unit 3 does not include the measurement target existence determination unit, and the position acquisition unit 339 displays the screen of the edge 285 of the measurement target portion 284 according to the instruction received from the movement instruction reception unit 333. The upper coordinate value is acquired as the coordinate value of the measurement position of the measurement object 20.

  FIG. 18 is a flowchart showing a processing procedure of the CPU 33 of the control unit 3 of the image measuring apparatus 1 according to the second embodiment of the present invention. Since the processing procedure of the second embodiment is the same as that up to step S1603 of the first embodiment until the longitudinal direction of the main body is aligned with the dimension direction of the measurement object, the description up to step 1603 is omitted.

  As shown in FIG. 18, the CPU 33 of the control unit 3 displays an image showing the movable measurement unit on the displayed image in the longitudinal direction of the image showing the main body, and the image showing the detection unit shows the edge of the measurement target portion. An instruction to move in the direction approaching the image is received (step S1801), and the coordinate value of the edge on the screen is acquired as the coordinate value of the measurement position in accordance with the received instruction (step S1802). On the screen, an image showing the movable measurement unit is displayed so that the detection unit moves until it touches the edge. The movable measurement unit temporarily touches the other edge, for example, at the position where the detection unit touches the edge. Until fixed.

  The CPU 33 moves the image indicating the fixed measurement unit on the displayed image in the longitudinal direction of the image indicating the main body and in the direction in which the image indicating the detection unit approaches and opposes the image indicating the edge of the measurement target portion. The instruction is accepted (step S1803), and the coordinate value of the edge on the screen is acquired as the coordinate value of the measurement position according to the accepted instruction (step S1804). On the screen, an image showing the movable measurement unit is displayed so that the detection unit moves until it touches the edge, and the fixed measurement unit temporarily calculates, for example, an actual measurement value of the measurement target portion at a position where the detection unit touches the edge. Until fixed.

  The CPU 33 calculates an actual measurement value of the measurement target portion based on the acquired coordinate value of the measurement position, that is, the coordinate value of the edge on the screen (step S1805).

  Note that when processing up to step S1802 is performed, the processing of step S1804 may be performed without receiving the instruction of step S1803, and an image showing a fixed measurement unit that moves to a position where the detection unit contacts the edge may be displayed. .

  Further, the fixed measurement unit may be moved simultaneously with the movement of the movable measurement unit in the process up to step S1802. When both measurement units are moved simultaneously, in addition to movement by mouse operation, input from the keyboard, etc., some input device, for example, pressing a predetermined key, etc., triggers both measurement units until the detection unit touches the edge You may make it move. For example, when setting the trigger by dragging the entire measuring instrument with the mouse as a trigger, every time the measuring instrument is moved by dragging the mouse, it is possible to automatically measure between the edges where the detection unit of the measuring unit is located. Measurement speed can be improved. In addition, when the above-mentioned trigger is generated, in addition to the movement from the position of the measurement unit at the time when the trigger is generated, the measurement unit may be temporarily expanded to move from a preset initial position. .

  As described above, according to the second embodiment, the image showing the detection unit is accurately touched with the image showing the edge only by moving the image showing the detection unit in the direction of the image showing the edge of the measurement object. Even if you do not operate it, you can automatically touch it, and you can measure it easily and quickly by intuitive operation on the screen so that the dimensions of the measurement object are actually measured with a measuring instrument. it can.
