Binary Edge and Gray Edge
These checkers detect in the same method of Binary Edge checker and Gray Edge checker. The X/Y
coordinates of the detected edge is considered as a base position.
They also have the Center detection function which decides a base position by calculating the middle of the
detected two points both in horizontal and vertical directions.
Only one direction either horizontal or vertical can be set.

method of Feature Extraction checker.
It considers the detected coordinates of the gravity center as a
base position.
Matching

Matching checker.
The output point of the detected object will be considered as
the base position.
Smart Edge (Circle)
This checker detects a virtual circle in the same method of "Detect
Mode: Radius" for Smart Edge (Circle).
The coordinate of the center of the detected virtual circle will be
considered as the base position.
If a whole circumference cannot be captured, or for a rounded angle,
the position detection is possible.
