This repository is a compression library for cwipc pointcloud objects. It is part of the cwipc suite, https://github.com/cwi-dis/cwipc, and should generally be installed or built as part of that suite.

cwipc_codec

This distribution contains a compressor and decompressor for pointclouds. It uses the cwipc abstract object to represent pointclouds.

It is a modified version of the cwi-pcl-codec distribution, from http://github.com/cwi-dis/cwi-pcl-codec. Both distributions share the same codec, described in the following journal paper:

(R. Mekuria, K. Blom, and P. Cesar, "Design, Implementation and Evaluation of a Point Cloud Codec for Tele-Immersive Video," IEEE Transactions on Circuits and Systems for Video Technology, 27(4): 828 -842, 2017

When cwipccodec is built from source (as part of the _cwipc suite) it is possible to use the codec using the same API as specified in that paper and in the cwi-pcl-codec repository. Simply add the include (and possibly source) directory to your project.

Use

  • cwipc_encode compresses a .ply pointcloud file to a .cwicpc compressed pointcloud file.
  • cwipc_decode decompresses a .cwicpc compressed file to a .ply pointcloud file.
  • cwipc_grab --compress will compress pointclouds before saving them to disk.
  • cwipc_view --playback will decompress .cwicpc files on the fly.
  • The various tools that produce or consume pointcloud streams will use the encoder and decoder by default.

Check include/cwipc_codec/api.h to see how to use the codec from your code. The Python API is nearly identical, inspect the cwipc.codec module.

Evaluation program

When building from source there is a test program included:

  • evaluate_compression allows for evaluation of the algorithm, see its readme file for details.
