Andy Zeng's Code Collection

A growing collection of open-source code that I've written over the years. Includes a diverse set of functions that are useful and non-trivial to implement for fast-prototyping in computer vision and robotics research.

Volumetric TSDF Fusion of Multiple Depth Maps

CUDA/C++ code to fuse multiple registered depth maps into a projective truncated signed distance function (TSDF) voxel volume, which can then be used to create high quality 3D surface meshes and point clouds.

  •  NVIDA GPU with CUDA support
  •  OpenCV (tested with OpenCV 2.4.11)

See Github repository here. The demo fuses 50 registered depth maps from a directory into a projective TSDF voxel volume, and creates a 3D surface point cloud and mesh.
