FitSegmentToRidges3D
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | Vision3DStandard |
Performs a series of 1D ridge detections and finds a segment that best matches the detected points.
Applications: Precise detection of a thin straight line, whose rough location 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: outRidges, outDeviationProfile, outInliers, outHeightProfiles, outResponseProfiles.
