With Scorpion Tool Components we strive to make it easy. The STC-0028-PointExtrema calculates the extremal point based on three or more points. This is needed to perform sub-pixel width measurement in the sample below.
How we solve to locate the outer-most points:
- Locate the six objects with TemplateFinder3
- Locate edge points with SingleLineFinder
- Use STC-0028-PointExtrema to estimate the outer-most point with an 2 or 3th order polynom
