Have you ever had trouble detecting an edge with a vision system? Did you know it's possible to adjust the edge detection level while viewing the edge intensity waveform? It is also possible to apply corrections at all times so that the maximum of the differential absolute value can be 100% in order to stabilize the edges for actual lines. This ensures that detections are stable even if light intensity fluctuates.
100% edge intensity correction
The shading difference between the background and the pattern is sufficient, so stable detection is possible.
The shading difference between the background and the pattern is small, but stable detection is possible.
Detection of up to 5000 edges and points
Wrong detection with two edges
Measured with multiple points to eliminate abnormal points
The detection is influenced by the points in this area.
Unwanted points are eliminated, and detection of the circle is made possible.
Edges along profiles can be found to calculate best fit lines and circles on geometric shapes for measurement and inspection.
Through-hole center detection
Profiles can be used to find the width of features or measure the diameter of circles and rings.
A reference profile is found on the basis of the edge and any deviations from the reference profile are considered defects. This is especially useful for burr and flaw inspections.
