The Various Modes for Position/Rotation Adjustment Checkers
Gray scale edge checker: Vertical detection rotation adjustment
Gray scale edge checkers are used as the base checkers, and the amount of
adjustment ∆Y, ∆θ (angle of rotation) is calculated from the results of two vertical
checkers.
Shapes available are lines and planes, with a mixture of the two being possible.
Since the amount of adjustment is calculated from the results of two base checkers, the
reference position cannot be set unless two checkers are set. Edge detection is
performed in Front detection position mode.
The reference point is the centre point of the coordinate obtained by checker 1 and the
coordinate obtained by checker 2.
