Tracking Deformable Objects with Point Clouds

This is an implementation of the tracking algorithm of the paper

Tracking Deformable Objects with Point Clouds
John D. Schulman, Alex Lee, Jonathan Ho and Pieter Abbeel
In the proceedings of the International Conference on Robotics and Automation (ICRA), 2013.

(website: http://rll.berkeley.edu/tracking/)

This implementation tracks cloth only, using a position-based dynamics model (Mueller et al. 2007). The cloth simulation does not support self-collisions, unlike the Bullet-based simulation that was used in the original implementation used for the experiments in the paper.

Dependencies

Required:

  • Python 2.7
  • PyOpenGL >= 3.0.1
  • pygame >= 1.9.1
  • python-opencv
  • h5py
  • numpy
  • PCL >= 1.6
  • Boost >= 1.48, including Boost Python
  • Eigen 3

Optional:

Building and running

  1. Download this source code, e.g. into $SOURCE_DIR
  2. Make a build directory $BUILD_DIR
  3. cd $BUILD_DIR
  4. cmake $SOURCE_DIR
  5. make
  6. Add directories to $PYTHONPATH: echo 'export PYTHONPATH=$SOURCE_DIR:$BUILD_DIR/lib:$PYTHONPATH' >> ~/.bashrc
  7. To run the tracker with example data (recorded depth camera videos): python $SOURCE_DIR/scripts/tracker.py --input=recording.h5 [--gpu]
