11.1 Gray Scale Edge Checkers
Scan Method
Two different scanning methods are supported for gray scale edge
checkers: Single and projection. The default is single.
Single scanning is a method which is beneficial for detecting edges on
workpieces where the edges are not straight lines (degraded or rounded
edges, or uneven surfaces).
Projection scanning is a method which enables the reliable detection of
edges that are present, even if the surface of an object is rough, the gray
scale image is grainy, and individual edges do not stand out.
−
Single scanning
A method of edge detection where the inspection area is scanned
horizontally for each individual pixel in the scanning direction. Scanning is
performed according to four parameters, scan pitch, filter, width, and
average area, and it is relatively unaffected by noise, enabling reliable edge
detection.

Projection scanning
Projection scanning is a method for images where the gray scale image is
grainy and individual edges do not stand out well. Reliable edge detection
can be achieved by averaging the brightness in the vertical direction and
using the integrated image data produced as the basis for edge detection in
the scanning direction.
Images that have undergone projection scanning can be confirmed from
