Angle
You can use the angle function to inspect the angle between two edges. The unit of angle is
º
(degree).
Angle measures angle of crossing point which is between two edges of registered arrows.
It sets the pass range based on the angle between two registered edges. The measured angle of
the inspection target within the pass range is regarded as Pass, while the measured angle of the
inspection target out of the pass range is regarded as Fail.

Description
1
Pass range
It sets the pass/fail range of angle.
Lower limit Measured ROI Upper limit
for pass angle value for pass
2
Edge threshold A/B
It sets threshold to detect edge.
Only edges with high contrast can be detected in high edge threshold,
while edges with low contrast also can be detected in low edge
threshold.
3
Automatic teaching
Even if user set the pass range, it teaches pass range based on the
pixel of ROI.
4
ROI type
It sets type of ROI to inspect.
In the ROI area, the program scans the edge in the arrow direction
and firstly detected edge becomes standard for inspection.
(two arrows)
5
OK/Cancel
It registers work to work group or cancel to register.
※
Threshold is the boundary value when a value is discontinuously changed.
