Position and Rotation AdjustmentOCR Type A2306 − 56.2 The Various Modes for Position/Rotation Adjustment CheckersGray scale edge checker: Horizontal detection rotation adjustmentGray scale edge checkers are used as the base checkers, and the amount ofadjustment ∆X, ∆θ (angle of rotation) is calculated from the results of two horizontalcheckers. Shapes available are lines and planes, with a mixture of the two beingpossible.Since the amount of adjustment is calculated from the results of two base checkers, thereference position cannot be set unless two checkers are set. Edge detection isperformed in Front detection position mode.The reference point is the centre point of the coordinate obtained by checker 1 and thecoordinate obtained by checker 2.Gray scaleedge checker 2(for rerference)Gray scaleedge checker 1(for rerference)Detection point
