FitPathToEdges3D
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | Vision3DStandard |
Performs a series of 1D edge detections and creates a path from the detected points.
Applications: Tracing of an object contour, whose rough location and shape is known beforehand.
Syntax
C++
C#

Optional Outputs
The computation of following outputs can be switched off by passing value atl::NIL
to these parameters: outEdges, outDeviationProfile, outHeightProfiles, outResponseProfiles, outPathSegments.
