Positional Deviation Measurement
4
4. On the settings for the gray scale search conditions (page 4-4), register the object by surrounding
it with a square window, regardless of the shape of the object to be measured.
Example
When triggered to store the reference image, the system will store various views of the object in
memory by rotating the image, 10 degrees at a time.
When the angle range is set to –360˚ (Rotation angle unit : 10)
5. Specify a search area that is large enough to include various positional deviations of the object.
6. When starting the measurement, the system will execute a gray scale search of the captured
image based on the stored reference images, which were created by rotating the basic image, 10
degrees at a time in step 3 above.
Note: When "NO" is selected for the "DTECT ANGL" (rotation angle detection) in the previous page
after registering the reference image, a "Reference image condition mismatch" error will occur
when executing the measurement.
