PointCloudSegmentation-V2

Modification: (1) use nanoflann.cpp to replace the ann library; (2) remove some cpps

Three algorithms on point cloud segmentation used in the following paper:

Pairwise Linkage for Point Cloud Segmentation, Xiaohu Lu, etc. ISPRS2016. https://github.com/xiaohulugo/xiaohulugo.github.com/blob/master/papers/PLinkage_Point_Segmentation_ISPRS2016.pdf

*The algorithm used in the ISPRS2016 paper is ClusterGrowPLinkage.cpp

Prerequisites:

  1. OpenCV > 2.4.x
  2. OpenMP

Usage:

  1. build the project with Cmake
  2. run the code
  3. see main.cpp for interfaces/demos

Docker: (For linux)

  1. Build the docker image by running docker build -t opencv:cpp . to build the docker image with name opencv and tag cpp
  2. Modify the code as you wish. Also the default data folder for test is ./data in the root path.
  3. Modify the test_segment.sh. This is the script the container will run after it is set up.
  4. Run the following command in the root path of the project.
docker run -it --rm \
    -v $(pwd):/pointSegment \
    opencv:cpp \
    /pointSegment/test_segment.sh

Performance:

Please cite these two papers if you feel this code useful:
