Sub-pixel processing allows one pixel on the light receiving element to essentially be processed as 100 or more pixels. This allows for highresolution measurement even with a wider field of view.
The shape of a line or circle used for measurement is recognized by
the least square fit algorithm using approximately 100 points
detected automatically. Using many points ensures stable
* The exact number of points is user adjustable for optimal detection.
During the extraction of a line or circle, the system eliminates the influence of burrs or chips by ignoring points at abnormal locations in comparison with other points. It is also possible to set the system to interrupt measurement when burrs or chips are found.
