Detailed Description
template<typename T>
struct PointMatcher< T >::ErrorMinimizer
An error minimizer will compute a transformation matrix such as to minimize the error between the reading and the reference.
Typical error minimized are point-to-point and point-to-plane.
The documentation for this struct was generated from the following files:
- PointMatcher.h
- ErrorMinimizer.cpp
