Judgement result
Number of detections
Correlation value
X coordinate of the position where the model is detected.
Y coordinate of the position where the model is detected.
Angle of the position where the model is detected.
Measurement image

Green: Matched model points
Yellow: Model points matched but with different directions
Red: Unmatched model points
• If the variability for good workpieces is large.
Decrease [Candidate LV].
• If there are large differences in the shape of individual workpieces.
Raise [Acceptable distortion level], if the correlating value is decreased
when you change the work Piece.
• Except for the work pieces shape can be detected.
Raise [Edge Level], if work's dirty point or fine patterns are miss-detected.
• It could be not able to measure in pixel unit.
Check [High-Prec.], if the accuracy of measurement coordinates is low.
• Detected target can be found too much.
Raise [Acceptable distortion level] if miss-detected is occurred, e.g. place where is
no work piece or similar to work piece shape are detected.
• Miss-detection can be occurred because there are many edges back on work pieces
P target edges are not able to be detected.
