[0003] At present, when using traditional image measuring instruments, the measured object is generally placed directly on the image measuring instrument. For some objects with insufficient flatness, the object will have a certain angle when measured by direct placement. At this time, the image measuring instrument will cause a certain deviation in the measurement of the object. In addition, due to the lack of positioning effect due to direct placement, it is easy to cause the movement of the object due to external vibrations, resulting in deviations in the measurement of the image measuring instrument. For this reason, the utility model proposes an image measuring instrument with auxiliary positioning function. Utility Model Content
