CHECK
It is also possible to set the binary level so that measurement is performed
only for an intermediate density range.
Edge
The edge registration method can be used when the measurement object is
rectangular.
Draw 4 regions. One edge is detected from each region and that becomes the
reference position.
1.
Setting Edge Detection Conditions
Set the direction to search for the 4 edges and the density change as the
measurement conditions.
Region 2
Region 3
Line connecting edge points
found for regions 0 and 1.
Search coordinates (cross point of lines)
Cross point not registered as reference
position if outside the model region.
