Determine alignment for:
Select the type of part location. You can determine either offset and
rotation on two edges, offset and rotation on three edges, only horizontal or only vertical offset. A
shorter processing time is required with fewer edges.
Depending on whether you wish to align to one or two edges, you must then draw the search lines
directly in the image using the mouse. Hold the left mouse button depressed during this.
Position the search lines such that the sought contour is intersected as closely as possible to the
middle. The first contour is detected which intersects the search line along the search axis. You can
correct the positioning at any time.
With long edges it is advisable to search the main reference edge with two search lines.
Enter the criteria:
Min. edge length:
You must also specify whether a short, medium or long edge is to be sought.
Using User defined, you may manually enter the length of an edge (5-1000 pixels)
.
Transition:
You must specify whether each edge can progress from bright to dark or from dark to
bright (device dependant).
Minimum contrast:
Specify whether you are searching for an edge with sharp or weak contrast.
