Currently it implements the SVD-based point-to-point algorithm as well as the linearized point-to-plane algorithm. It also supports outlier rejection and is accelerated by the use of kd trees as well as a coarse matching stage using only a subset of all points. If you distribute a software that uses libicp, you have to distribute it under GPL with the source code. +++++++++++++++++++++++++++++++++++ + COMPILING MATLAB WRAPPERS + +++++++++++++++++++++++++++++++++++ If you want to use libicp directly from MATLAB you can easily do this by using the MATLAB wrappers provided. They also include some demo files for testing your configuration. First, configure your MATLAB MEX C++ compiler, if it is not yet configured (mex -setup). Under Linux you might use g++, under Windows I compiled it successfully with the Microsoft Visual Studio Express 2008 compilers. 1) Change to the libicp/matlab directory 2) After running 'make.m' you should have a MEX file called 'icpMex' 3) Now try to run 'demo_2d.m' or 'demo_3d.m' +++++++++++++++++++++++++++++++++++ + BUILDING A C++ LIBRARY + +++++++++++++++++++++++++++++++++++ Prerequisites needed for compiling libicp using c++: - CMake (available at: http://www.cmake.org/) - Boost (available at: http://www.boost.org/) Note: Please make sure that the boost headers can be found! (Add /usr/local/include to your include path if you have installed them locally) Linux: 1) Move to libicp root directory 2) Type 'cmake .' 3) Type 'make' 4) Run './icp' (demo program) Windows: 1) Start CMake GUI 2) Set directories to libicp root directory 3) Run configure, configure and generate 4) Open the resulting Visual Studio solution with Visual Studio 5) Switch to 'Release' mode, build all and run the demo program For more information on CMake, have a look at the CMake documentation. For more information on the usage of the library, have a look into the MATLAB wrappers and into the documentation of the header file icp.h.
