NOTE: This repository also contains an implementation of ICP, directional ICP and robust ICP. Other algorithms evaluated in these papers, for which source code is not included in this repository, include:

• GICP

  downloaded from http://www.robots.ox.ac.uk/~avsegal/generalized_icp.html

  see IMLP paper for minor modifications required for termination condition and to set covariance matrices

• CPD

  downloaded from https://sites.google.com/site/myronenko/research/cpd

  see IMLP paper for minor modifications required for termination condition

NOTE: To run experiments described in the IMLP paper, go to https://github.com/sbillin/IMLP. Compile the source code following instructions there (or here) and run the experiments in the PLOSONE folder.

Required Software Dependencies

• Visual Studio for Windows (http://www.visualstudio.com/downloads/download-visual-studio-vs)

  application was developed in Visual Studio 2013

• CISST Libraries (https://github.com/jhu-cisst/cisst/)

  must compile this from source (instructions below)

• WildMagic5 Libraries (http://www.geometrictools.com/Downloads/Downloads.html)

  requires: Wm5Core.lib, Wm5Mathematics.lib

  must compile these from source (instructions below)

  included in dependencies folder

• DLib (http://dlib.net/)

  for iterative solutions to our minimization problems

  included in dependencies folder

• Numerical Recipes (http://numerical.recipes/)

  needed only for G-IMLOP and GD-IMLOP algorithm; other algorithms don't use it and the code can be built without it

• PLY_IO Library (if using Matlab)

  for reading/writing PLY files in Matlab

  included in dependencies/Matlab Dependencies folder

NOTE: Visual Studio 12 2013 Win64 was used successfully when creating this README. Visual Stuido 14 2015 Win64 did not work due to errors such as cisstNetlib_f2c.lib(endfile.obj) : error LNK2001: unresolved external symbol __imp_sprintf. This issue has not been solved and it is recommended to build the cisstICP application using Visual Studio 2013.

Instructions for Compiling Dependencies

CISST Libraries:

https://github.com/jhu-cisst/cisst/

• Clone cisst repository from github

  git clone https://github.com/jhu-cisst/cisst/

  only jhu-cisst/cisst required (not cisst-saw, etc.)

• Create a build directory cisst_build alongside (not inside) the cisst directory that was cloned from git

• Create Visual Studio solution for CISST Libraries using CMake <br />

  run CMake on cisst source directory with build directory set to cisst_build

  -- check boxes for libraries: CISST_cisstCommon, CISST_cisstVector, CISST_cisstNumerical, CISST_cisstOSAbstraction
  
  -- uncheck boxes for cisstMultitask, cisstMutliTask_, cisstParameterTypes, cisstRobot_ 
  
  -- check box for CISST_HAS_CISSTNETLIB 
  

  configure with Visual Studio 12 2013 Win64 as the compiler -- check box: CISSTNETLIB_DOWNLOAD_NOW

  configure and generate project

  open the cisst_build/cisst.sln file and build in Visual Studio with build mode set to Release and x64

WildMagic5 Libraries:

http://www.geometrictools.com/Downloads/Downloads.html These libraries are used solely for the closed-form implementation of computing the decomposition of a 3x3 covariance matrix. The libraries are no longer available online from their author, but they are included in the dependencies folder of the cisstICP repo.

• Build WildMagic5 <br />

  extract source from the WildMagic5p13.zip file located in the dependencies folder

  open the GeometricTools\WildMagic5\WildMagic5Wgl_VC120.sln file in Visual Studio and set build configurations to Release and x64

  compile Wm5Core.lib and Wm5Mathematics.lib by right clicking LibCore_VC120 and LibMathematics_VC120 and selecting build

• See website of WildMagic5 for more instructions on this

Dlib Libraries:

• Extract source from the dlib-a8.6.7z file located in the dependencies folder

Numerical Recipes:

• License to use the source code for this must be bought (usually available on amazon along with the book)
• Contact sinha(at)jhu(dot)edu for modifications in numerical recipes code once license is obtained

RPly Libraries:

• Extract source from the rply-1.1.4.zip file located in the dependencies folder

PLY_IO Libraries:

If using Matlab

• Extract source from the PLY_IO file located in the dependencies/Matlab Dependencies folder

Instructions for Compiling Source Code

These instructions are based on the Windows platform with VisualStudio 2013. The output is a static library (cisstICP.lib).

Compile cisstICP Library:

• Clone cisstICP repository from github

  git clone https://github.com/AyushiSinha/cisstICP

• Create a build directory cisstICP_build within the cisstICP directory that was cloned from git

• run CMake on source directory cisstICP

  specify paths to cisstICP source code and build directories (cisstICP and cisstICP_build) and configure

  set cisst_DIR to location of CISST Library build cisst/cisst_build and configure again. If the compiled CISST libraries were found correctly by CMake, then CISST_USE_FILE should now automatically contain a path to the file Usecisst.cmake

  specify path to WildMagic5 base directory by setting WM5_BASE_DIR to cisstICP/dependencies/WildMagic5p13/GeometricTools/WildMagic5 (other WildMagic5 fields should auto-detect)

  set DLIB_INCLUDE to the path to the extracted dlib folder

  set RPLY_DIR to the path to cisstICP/dependencies/rply-1.1.4

  optionally, check USE_EXTRA_ALGORITHMS to include IMLP_CP (closest point), IMLP_MD (mahalanobis distance) and RobustICP in the build

  configure and generate project

• Build cisstICP library in Visual Studio <br />

  open cisstICP_build/cisstICP.sln

  build with build mode set to Release and x64

Compile cisstICP_App:

• Create a build directory cisstICP_App_build within the cisstICP_App directory

  specify paths to cisstICP source code and build directories (cisstICP_App and cisstICP_App_build)

• run CMake on source directory cisstICP_App and configure <br />

  set cisst_DIR to the path to the cisst/cisst_build folder and configure again. If the compiled CISST libraries were found correctly by CMake, then CISST_USE_FILE should now automatically contain a path to the file Usecisst.cmake

  set DLIB_INCLUDE to the path to the extracted dlib folder.

  set WM5_BASE_DIR to the path to cisstICP/dependencies/WildMagic5p13/GeometricTools/WildMagic5

  set MATLAB_ENGINE_INCLUDE_DIR and MATLAB_ENGINE_LIB_DIR to your system paths for Matlab, such as C:/Program Files/MATLAB/R2015a/extern/include and C:/Program Files/MATLAB/R2015a/extern/lib/win64/microsoft (these paths will change depending on the Matlab version).

  set cisstICP_LIB to the path to /cisstICP/cisstICP_build/Release/cisstICP.lib

  set cisstICP_LIB_INCLUDE to the path to cisstICP/cisstICP

  configure again and Generate

• Build cisstICP_App library in Visual Studio <br />

  open the cisstICP_App_build/cisstICP_App.sln file in Visual Studio, set the build options to 'Release' and 'x64', and build the solution.

Compile matlabICP Library:

This library provides a Matlab interface to the C++ code of the cisstICP Library. This library is not maintained by me.

• Create a matlabICP_build folder alongside the matlabICP folder in the cloned re
