FitCircleToStripe3D
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | Vision3DStandard |
Performs a series of 1D edge detections and finds a circle that best matches the detected points.
Applications: Precise detection of a circular object or hole, whose rough location is known beforehand.
Syntax
C++
