applications
1
Parameter for teaching
2
Parameter for evaluation
The angle information displayed in the Results area and available via the EtherNet/IP connection is only a rough estimation. To help
improve the precision of angle data, the Contour Matching parameters should use the following settings:
Edge contrast: set value as high as possible
Edge gradient: set value as low as possible
Min. edge length: set value as high as possible
Search mode: Complete Search
Edge width: set value as low as possible

Description
Screen Shot
Min. scaling
2
Minimum factor for scaling the size of the contour.
Values = 0.5 … 1.0, default = 1.0
Max. scaling
2
Maximum factor for scaling the size of the contour.
Values = 1.0 … 1.5, default = 1.0
Starting angle
2
Angle at which the search starts. Search in clockwise
direction.
Values = -180
° … 179°, default = -10°
0
° = 12:00am on a clock
Total angle
2
Maximum search angle. Used to reduce the angular
positions that are inspected, so that only a contour
with minimal displacement from the original angular
position is matched. E.G. – The application is to
confirm that a part is in the correct orientation, so
reduce the Total angle. If the part is not in the correct
orientation, the contour will not be found.
Threshold Contour
2
Threshold Contour defines the minimum evaluation
score for the inspection to pass. Threshold is adjusted
by the slider.
Values = 0.00 … 1.00 in increments of 0.05
The threshold value is depicted by a small vertical black
line on the detector results bar graph when the sensor
is in run mode.
