Tool

[Angle]

The angle that the detected straight line forms with the X axis of the image coordinate
system. Turn clockwise from the X axis positive.(See coordinate system (p 111))

[Num of contour]

The number of contours detected.

[Integrity]

The percentage of cells that extracted the edge (extraction point) of each cell in the
guide frame.

Measure burr / crack

Compare the approximate line obtained by geometric fitting using the metrology
model with the target image. This makes it possible to measure defects such as burrs
and cracks.
