Scan Edge Width

Section 3-10

3-10 Scan Edge Width

This processing item detects the position of the measurement object by using
the change in color within the measurement region.By dividing the measure-
ment region, you can get the following values.

• Local width of the work

• Average width of the work

• When getting several widths of a measurement object

• To find the width of a measurement object

Using a Expression, the width of a measurement object can be calculated
from the difference between two edge positions.

The region is divided equally.
