This is an ICP toolbox for 3D point clouds . Its mainly coded in Matlab but some functions have been written in C++ for optimization purposes. To solve the NNS this toolbox employees:
ANN library,
GLTreePro (which are included in the companioning zip and already compiled for Windows(32-bits) and Linux (32/64-bits)) and Box Search Matlab version .
This toolbox includes different data association metrics such as: point-to-point, point-projection-to-plane and the Hybrid Hierarchic from my IROS 2009 paper. It also includes different filters for data association.
The user can also select different distance metrics.
