Open Source Kinect Fusion – Update

There is an update on the open source implementation of Microsofts Kinect Fusion Algorithm by developers of the open source Point Cloud Library.

They improved on the Microsoft implementation with their algo called KinFu Large as they are able to scan multiple volumes in on pass allowing to scan larger scenes in one go.

The point cloud library (PCL) is available as prebuild binaries for Linux, Windows and OSX as well as in source code from their svn repository. The code relies heavily on the NVidia CUDA development libraries for GPU optimizations and will require a compatible GPU for best results. Information on how to setup your own build environment and the required dependencies is available from their site.

Besides the Kinect the library supports several other sensor via OpenNi.
