This is a lightweight python script that fuses multiple registered color and depth images into a projective truncated signed distance function (TSDF) volume, which can then be used to create high quality 3D surface meshes and point clouds. Tested on Ubuntu 16.04.

An older CUDA/C++ version can be found here.

• Python 2.7+ with NumPy, PyCUDA, OpenCV, Scikit-image and Numba. These can be quickly installed/updated by running the following:

  pip install --user numpy opencv-python scikit-image numba

• [Optional] GPU acceleration requires an NVIDA GPU with CUDA and PyCUDA:

  pip install --user pycuda

This demo fuses 1000 RGB-D images from the 7-scenes dataset into a 405 x 264 x 289 projective TSDF voxel volume with 2cm resolution at about 30 FPS in GPU mode (0.4 FPS in CPU mode), and outputs a 3D mesh mesh.ply which can be visualized with a 3D viewer like Meshlab.

Note: color images are saved as 24-bit PNG RGB, depth images are saved as 16-bit PNG in millimeters.
