whu-lyh/VGS-Segmentation

The source code for point cloud segmentation.

Voxel- and graph-based point-cloud-segmentation

This is the source code for the algorithm of Voxel- and Graph-based Segmentation (VGS/SVGS).

Environment:

The code is written in C++ and tested in VS2015.

Dependence:

The code depends on the following third-party libraries: -PCL 1.8.1.

How to use these codes：

please refer to "Use_Test"

The "input_vector" encodes the input parameters (see "Task_File_VGS.txt" and "Task_File_SVGS.txt"), you can change it according to your demands.

Special thanks to M.Sc. Dong Lin from TU Dresden for correcting bugs in the codes!

Reference:

Testing dataset (Town_Test.pcd) is cropped from ETH Zurich dataset： http://semantic3d.net/
