Running Parameter
Edge Type: It includes strongest edge, last edge and first edge.
- Strongest Edge: find the edge point group with the largest gradient threshold,
and then fit it into a straight line.
- Last Edge and First Edge: find the first / last line that meets the condition.
Edge Polarity: it has three polarities, including dark to light, light to dark and any.
Edge Threshold: The edge threshold is the gradient threshold, ranging from 0 to 255. Only
edge points whose edge gradient threshold is greater than this value are detected. The larger the
value is, the stronger the anti noise ability is, the less the number of edges is, and even the target
edge points are screened out.
Filter Size: It can filter the noise. The larger the value, the stronger the anti noise ability,
and the less the number of edges obtained. At the same time, it may also cause the target edge to be
screened out.
Caliper Number: The edge points are clamped by multiple calipers to define the number
of calipers.
Revert Find Orient: After enabling it, the software will revert the information of line start
point and line end point.
Angle Normalization: After enabling, the angle of outputted line is -90° to 90°. if it is not
enabled, the angle of outputted line is -180° to 180°.
Reject Number: Refer to Find Circle.
Distance to Remove: Refer to Find Circle.
Projection Width: It is the caliper width, several searched edge points are arranged in order
in the ROI. This parameter describes the width of the area where the edge points are scanned for the
ROI.Increase the value within a certain range to obtain more stable edge points .
