Position and Rotation AdjustmentOCR Type A2306 − 36.1 Position and Rotation Adjustment6.1 Position and Rotation AdjustmentPosition and rotation adjusters find the difference of adjustment required between thecoordinates recorded as setup (reference point) and the coordinates found whenexecuted. Individual checkers come under a position and rotation adjuster group, andby applying the amount of adjustment, checker coordinates can be adjusted by anappropriate amount for inspection. The detection methods available for position androtation adjusters are binary edge checkers, gray edge checkers, feature extractors,and matching. (Settings for base checker.) Base checkers with different methods ofinspection cannot be combined into one position and rotation adjuster. For instance, forposition adjustment, it is not possible to use a binary edge checker for horizontaladjustment and a feature extractor for vertical adjustment.14 different position and rotation adjuster modes are available with different types ofbase checker and different methods of inspection.TYPE[ 1] :2.
