Dense Stereo Range Sensing with Marching Pseudo-Random Patterns
2007
Fourth Canadian Conference on Computer and Robot Vision (CRV '07)
As an extension to classical structured lighting techniques, the use of bi-dimensional pseudo-random color codes is explored to perform range sensing with variable density from a stereo calibrated rig and a projector. Pseudo-random codes are used to create artificial textures on a scene which are extracted and grouped in a confidence map to ensure reliable feature matching between pairs of images taken from two cameras. Depth estimation is performed on corresponding points with progressive
