CHECK
Draw a measurement region to include all the edges for detection.
When a measurement region is drawn, measurement is performed for the dis-
played image and the result is registered as the reference value (edge posi-
tion).
If the edge is not in the measurement region, measurement will not be possi-
ble. Make a region of a size and position that allows for movement of the range
of the measurement object.
