About the Software

This page contains software and instructions to compute features and descriptors, and fully automatically align range images using the 3D geometric scale-space analysis introduced in these papers.

MD5SUM

3DGSS depends on the Python libraries PIL, NetworkX, Numpy, Scipy, eigen, and libkdtree++, and requires cmake and an mp enabled compiler to compile.

The 3DGSS code requires that you provide range-grid PLY files as input. A range-grid PLY file is not the same as an ordinary PLY file. Instead of a list of vertices and a list of faces, it has a list of vertices and a list defining the valid or masked pixels in raster-scan order (left-to-right, top-to-bottom).
The Standford 3D Scanning Repository has many range images that can be used to test the code.

Usage

Please run make to compile the documents. 3dgss.py is the main program to execute.

To see the full usage of the program, simply run

				3dgss.py -h
			

The following are some sample usages.
