Abstract
A camera based depth mapping system. Depth information is coded with colors to make a laser-generated 3D depth map easier to interpret. In the event that the laser illumination is not sufficient, the depth information can have a low signal to noise ratio, i.e., the depth map can be noisy. Color noise reduction techniques are used to alleviate this problem.
