Abstract

The problem of relating projected and captured stripes, here called the Indexing Problem, has proved to be difficult to overcome reliably for stripe patterns in color structured light, due to color fidelity of the projector and the camera, the ambient light, texture of measured object and other factors. In order to solve the Indexing Problem, a new method is proposed. The method extract the center color stripe based on cluster analysis at first. We convert color coded image based on De Bruijn into weighted directed digraph, then match stripe according to coded values. The proposed method is the center of colored stripes as the basic decoding units. Results are significantly more rapid, accurate and reliable than previous attempts.
