• Filter Size: it is used to enhance the edge and suppress noise, and its minimum value is 1.
When the edge is blurred or there is noise interference, you can increase its value to make the
detection result more stable. If the distance between the edge and the edge is smaller than the filter
size, it will affect the accuracy of the edge location or even lose edge. This value needs to be set
based on the actual situation.
• 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.
• Edge Polarity: it has three modes, including dark to light, light to dark and any.
• Scan Width: it is used to describe the area width of searching edge point ROI, and the min.
value is 1. Within certain range, increasing this value can reduce the quantity of edge points.
Detection Results
• Peak X/Y: generate the X/Y coordination of the peak.
• Peak Score: Edge points, peak and their scores in peak detection are calculated by internal
caliper. Refer to caliper tool for the definition of scores.
• Peak Polarity: it is edge polarity: light to dark and dark to light.
• Peak Distance: it is the distance from the peak to one side of the ROI area, corresponding
to the search direction in the operation parameters.
• Edge Number: the number of edge points.
Edge Intersection
The tool of edge intersection is used to search the intersection of two edges, and the search direction
and polarity can be set according to the required intersection. When the two edges intersect, the
intersection is the target to be searched. When they do not intersect, the intersection is the
intersection of their extension lines. The basic parameters and result display have been explained in
the Tool Application. This section mainly describes part of the parameters.
