In step S11, the user preselects an object to be searched by template matching from images based on image data generated by imaging by the first imaging unit 11 or the second imaging unit 12. As an example, the control unit 40 displays a search target selection screen on the second display unit 19, and accepts a user's operation for selecting a search target. On the search object selection screen, various objects corresponding to various template files stored in the storage unit 35 are displayed to the user as objects that can be searched by the measuring instrument 1 . The user can select a target to be searched by the measuring instrument 1 on the search target selection screen by touching or the like. The control unit 40 expands the template file corresponding to the target selected by the user on the search target selection screen into a data arrangement suitable for template matching, and stores it in the temporary storage unit 34 . As an example, the control unit 40 expands, in the temporary storage unit 34, a search template based on the first template file corresponding to the first target selected by the user on the search target selection screen.

On the observation screen shown in FIG. 6 , as image items 100, images based on the display image data sequentially output by the first imaging unit 11 or the second imaging unit 12 and sequentially generated by the image processing unit 33 are sequentially displayed.

In step S12, when the control unit 40 determines that the position where the target search item 115 is displayed has been touched on the display surface 19a, it executes the target search function.

The image processing unit 33 stores one frame of image data extracted from the image data sequentially output by the first imaging unit 11 or the second imaging unit 12 in the temporary storage unit 34 as retrieval target image data. The image processing unit 33 may store image data obtained by cutting out a part of one frame of image data extracted from the image data sequentially output by the first imaging unit 11 or the second imaging unit 12 as search target image data in the temporary storage unit. 34. The image processing unit 33 may also store image data obtained by performing color correction processing on one frame of image data extracted sequentially from the image data sequentially output by the first imaging unit 11 or the second imaging unit 12 as search target image data in the temporary storage. Section 34.

In step S13, the control unit 40 executes template matching preprocessing.

As an example, the control unit 40 sets a search range in which template matching is performed on the search target image data stored in the temporary storage unit 34 . As an example, the control unit 40 sets the central portion of the image based on the search image data as the search range, and excludes the peripheral portion of the image based on the search image data from the search range. In addition, the search range may be specified by the user, for example, by operating the second display unit 19 or the like.

As an example, the control unit 40 predicts the size (size) of the object in the search target image based on the search target image data stored in the temporary storage unit 34 (for example, based on the focus lens position from the first imaging unit 11 or the second imaging unit 12). distance to the predicted target and the size of the target used), the size of the search template stored in the temporary storage unit 34 is enlarged or reduced according to the size of the predicted target.

As an example, the control unit 40 increases the gain of the first imaging unit 11 or makes the second The gain of the imaging unit 12 is increased.

In step S14, the control unit 40 executes template matching. As an example, the control unit 40 executes pattern matching using the search target image data and the search template.

In step S15, the control unit 40 judges whether or not the search for the object was successful.

When the control unit 40 determines that there is a part matching the search template in the search target image data, it regards the part of the search target image data that matches the search template as a target, and acquires The coordinates of the occupied area, the coordinates of the center point of the object in the search target image data, and the like. In this case, the control part 40 judges in step S15 that the object search was successful. The control unit 40 calculates the coordinates of the center point of the target by detecting intersection points of a plurality of straight lines formed on the target. For example, when the object is a quadrilateral, the control unit 40 calculates the coordinates of the diagonal vertices as the coordinate information of the area occupied by the object. When the control unit 40 determines that there are a plurality of parts matching the search template in the search target image data, each of the parts in the search target image data that match the search template is regarded as a target, and is used to determine the search template. A plurality of sets such as the coordinates of the area occupied by the object in the target image data and the coordinates of the center point of the target in the search target image data are obtained.

When the object is retrieved, the control unit 40 superimposes and displays a frame indicating the area where the object exists, for example, as shown in Fig. 8 , based on the coordinate information of the area occupied by the object. It is also possible to fill in the area where the target exists and show it.

When a plurality of objects are retrieved, the control unit 40 superimposes and displays a frame indicating an area where the object exists for each of the plurality of objects. The control unit 40 may allow the user to select a target to be collimated.

In step S16, the control unit 40 rotationally drives the horizontal angle driving unit 15 and the vertical angle driving unit 17 to align with the center point of the target. The control unit 40 may automatically execute the measurement once the center point of the target is collimated.

When the control unit 40 judges that there is no part matching the search template in the search target image data, it judges in step S15 that the target search has failed, and returns to step S13 to execute template matching preprocessing. The control unit 40 resets the search range for performing template matching on the search target image data stored in the temporary storage unit 34 . As an example, the control unit 40 sets an area adjacent to the previous search range as the search range. As an example, the control unit 40 changes the size of the search template.

In addition, as the setting procedure of the search range, for example, FIG. 9( a ) or FIG. 9( b ) can be exemplified. Numerals in FIG. 9(a) and FIG. 9(b) indicate the order of setting the search range. The object search is performed preferentially at the central part of the image based on the search target image data, and if no target is found, it is performed toward the peripheral part of the image based on the search target image data.

When a preset condition is satisfied, for example, when the control unit 40 judges that there is no portion matching the search template in the search target image data even after performing template matching a preset number of times, or even if When it is judged that there is no part matching the search template in the search target image data after template matching is performed on the entire range of the search target image data, the search target image data stored in the temporary storage unit 34 is updated. When updating the search target image data, the brightness of the image data may also be changed.

When the control unit 40 does not find the target, when the distance to something in the line-of-sight direction by the autofocus function is infinite, the template matching may not be re-executed, and the "distance is too far" After a message is displayed on the second display unit 19, the target collimation function is terminated.

When the target is not found, the control unit 40 may display a message such as "too dark" on the second display unit 19 to terminate the target collimation function when the brightness of the search target image data is below a predetermined value.
