PURPOSE: To provide a noncontact image measuring system which can display easily the part to be measured. CONSTITUTION: A monitoring image window 41 and a stage image window 42 are produced on a display screen of a CRT display. A monitored image showing a part of a workpiece 12 of which the image is picked up presently by a CCD camera is displayed in the monitoring image window 41, while a stage image being an overall image obtained by picking up the image of the workpiece 12 overall by the CCD camera is displayed in the stage image window 42. While it is made possible to specify an arbitrary position in the stage image, a position in a workpiece coordinate system corresponding to the position in the overall image of the workpiece 12 is calculated in response to this specification of the position, and the CCD camera is moved to the specified position in the workpiece 12. Therefore an enlarged image of a desired position in the workpiece 12 can be displayed in the display screen by a very simple operation. |
