deinitCompute()
| protected |
This method should get called after finishing the actual computation.
Definition at line 174 of file pcl_base.hpp.
getClassName()
| inlineprotectedvirtual |
Class getName method.
Definition at line 154 of file segment_differences.h.
getDistanceThreshold()
| inline |
Get the squared distance tolerance between corresponding points as a measure in the L2 Euclidean space.
Definition at line 126 of file segment_differences.h.
References pcl::SegmentDifferences< PointT >::distance_threshold_.
getSearchMethod()
| inline |
Get a pointer to the search method used.

getTargetCloud()
| inline |
Get a pointer to the input target point cloud dataset.
Definition at line 102 of file segment_differences.h.
References pcl::SegmentDifferences< PointT >::target_.
initCompute()
| protected |
This method should get called before starting the actual computation.
Internally, initCompute() does the following:
- checks if an input dataset is given, and returns false otherwise
- checks whether a set of input indices has been given. Returns true if yes.
- if no input indices have been given, a fake set is created, which will be used until:
- either a new set is given via setIndices(), or
- a new cloud is given that has a different set of points. This will trigger an update on the set of fake indices
