Compilation
The code is compiled using CMake and requires Eigen. It has been tested on Ubuntu 16.04 with gcc 5.4.0 and on Windows with Visual Studio 2015.
Follow the following steps to compile the code:
-
Make sure Eigen is installed. We recommend version 3.3+.
- Download Eigen from eigen.tuxfamily.org and extract it into a folder 'eigen' within the 'include' folder. Make sure the files 'include/eigen/Eigen/Dense' and 'include/eigen/unsupported/Eigen/MatrixFunctions' can be found
- Alternatively: On Ubuntu, use the command "apt-get install libeigen3-dev" to install Eigen.
-
Create a build folder 'build' within the root directory of the code
-
Run cmake to generate the build files inside the build folder, and compile the source code:
- On linux, run the following commands within the build folder:
$ cmake -DCMAKE_BUILD_TYPE=Release .. $ make- On windows, use the cmake GUI to generate a visual studio solution file, and build the solution.
-
Afterwards, there should be an exectuable file 'FRICP' generated.
Usage
The program is run with four input parameters:
- an input file storing the source point cloud;
- an input file storing the target point cloud;
- an output path storing the registered source point cloud and transformation;
- registration method:
0: ICP
1: AA-ICP
2: Ours (Fast ICP)
3: Ours (Robust ICP)
4: ICP Point-to-plane
5: Our (Robust ICP point-to-plane)
6: Sparse ICP
7: Sparse ICP point-to-plane
You can ignore the last parameter, in which case Ours (Robust ICP) will be used by default.
Example:
$ ./FRICP ./data/target.ply ./data/source.ply ./data/res/ 3
But obj and ply (Non-binary encoding) files are supported.
Initialization support
If you have an initial transformation that can be applied on the input source model to roughly align with the input target model, you can set use_init=true and set file_init to the initial file name in main.cpp . The format of the initial transformation is a 4x4 matrix([R, t; 0, 1]), where R is a 3x3 rotation matrix and t is a 3x1 translation vector. These numbers are stored in 4 rows, and separated by spaces in each row. This format is the same as the output transformation of this code. It is worth mentioning that this code will align the center of gravity of the initial source and target models by default before starting the registration process, but this operation will be no longer used when the initial transformation is provided. In our experiment, we directly use the output file of transformation matrix generated by Super4PCS as the initial file.
