Abstract
The algorithms presented in this paper are focused on the analysis of 3D scene using structured light technique. The light pattern which was projected on the scene consisted of horizontal stripes of different colors. These colors corresponded to the symbols creating the de Bruijn sequence. The first plane objects of analysed 3D scene were human hands. In this paper the discussion concerning important features of the structured light pattern is made. The focus is made on the analysis of the pattern corresponding to the de Bruijn sequence. The algorithm for computing the depth map of 3D scene using triangulation method is proposed. The most important part of the algorithm for the depth map evaluation is related with the extraction of colors from the stripes of the projected light pattern. The discussion concerning proposed algorithms for color detection is made and the results of the tests on HD images are described. The implementation of proposed methods using parallel programming with openCL architecture enabled crating real-time application.
