Work of Camera Calibration (1) : Source Code of EPnP-based

I. The reference  is from: 
   。http://cvlab.epfl.ch/software/EPnP/
   
II. About could not extract the source code of file in C++:
   。Have inquired the author, not yet to receive a response
   。Yet... I find the solution to solve the issue. The extracted file is in '.tar', 
        which need to use at least '7-Zip' to unpack it. Using WinRaR is not appropriate. 

        Here is some reference of this matter: 
        http://www.haskell.org/haskellwiki/How_to_unpack_a_tar_file_in_Windows

III. Today's process: 
     。Tracing the source code in Matlab (not finish, but is already to be performing 
         and have results which those authors wanted to demonstrate)
