This repo is my fork of the Chen Feng's AHC algorithm, please follow the instructions below to cite his work if you make use of this code.

We use this code for plane segmentation in our work CuFusion, if you're trying to run it, please clone this repo or download the source code here and add it to CuFusion for compilation.

Overview

This source code package contains our C++ implementation of the AHC based fast plane extraction for organized point cloud (point cloud that can be indexed as an image). There are three folders in this package:

• include

  Our C++ implementation of the algorithm with dependencies on OpenCV and shared_ptr (from C++11 or Boost).

• cpp

  Two example C++ console applications using our algorithm to extract planes from Kinect-like point cloud (depends on PCL), with a CMake script to help generating project files.

• matlab

  A matlab interface (fitAHCPlane.m) through MEX for using our algorithm in matlab. We also provide a wrapper class Kinect.m and kinect_ahc.m to do real-time plane extraction in matlab, partially depends on a 3rd-party toolbox Kinect_Matlab.

If you use this package, please cite our ICRA 2014 paper:

Version

1.0

Installation

C++ example

1. Install OpenCV, Boost and PCL (If you install PCL using their all-in-one installer, you directly get Boost installed as well).

2. Generate project file using CMake under either Windows or Linux.

3. Compile.

4. Run the compiled process: plane_fitter (first connect a Kinect to your computer!) or plane_fitter_pcd (first modify plane_fitter_pcd.ini accordingly!).

5. Enjoy!

Matlab example

1. In matlab:

cd WHERE_YOU_EXTRACT_THE_PACKAGE/matlab/mex

2. Run makefile.m

3. Select the directories for OpenCV_Include, OpenCV_Lib, and Boost_Include respectively

4. If everything compiles smoothly:

cd ..

5. Load a single frame we've prepared for you in matlab by:

load frame

6. Run our algorithm on the point cloud:

frame.mbs=fitAHCPlane(frame.xyz);
viewSeg(frame.mbs,640,480)

7. Enjoy!

8. If you want to play with the kinect_ahc.m with a Kinect, install Kinect_Matlab first.
