4.8 Adjusting Area Position (Position Adjustment)
4.8.1 What Is Position Adjustment?
If positions of checker areas are fixed, inspections cannot be executed properly when an object moved only a
short distance.
Position Adjustment allows inspecting properly even if an object is displaced, by detecting the current position
of the object and reflecting its shift amount from the base position to checkers.
You can set up to 1000 position adjustment checkers per type (when 10 blocks are used).
PV500 has multiple types of position adjustments to detect the position and the rotation angle of an object.
Position Adjustment (Horizontal/vertical shift amount)
After each checker detected the position of the object, Position Adjustment calculates the misalignment
between the object and the base position. To detect an object, select from the following six types.
Binary Edge / Gray Edge / Feature Extraction / Matching / Smart Edge (Circle) / Smart Edge (Line)
Position Rotation Adjustment (Horizontal/vertical position and angle shift amount)
Position/Rotation Adjustment detects position (coordinates) and angle of an object using checkers and
calculates the misalignment from the base position and rotating angle from the base angle.
To detect an object, select from the following five types.
Feature Extraction (Principal axis angle) / Matching (360-dgree) / Feature Extraction (2 checkers) /
Matching (2 checkers) / Smart Edge (Line)
Rotation Adjustment (rotated amount), Position Adjustment (horizontal/vertical shift amount)
Rotation Adjustment detects the angle of an object using checkers and calculates the rotating angle from the
base angle.
To detect an object, select from the following six types.
Binary Edge (Horizontal) / Binary Edge (Vertical) / Gray Edge (Horizontal) / Gray Edge (Vertical) / Smart
Edge (Line) (Horizontal) / Smart Edge (Line) (Vertical)
Note that the checker cannot be adjusted when camera numbers of referred position adjustment and the
following checker are different depending on the combination of the camera numbers. Refer to page
207 for
details.
