3D scan of a color object using a color structured light pattern

Abstract

Colour structured light with spatial neighbourhood is one of the famous techniques that are used to acquire 3D information. By projecting the pattern onto the targeted object and taking the image, the structured light is measured as coded words and the corresponding points could be found. Finally, the process to reconstruct 3D information could be solved using the principle of triangulation. A major group of this technique, normally, limited to the opaque and single neutral color surfaces. However, with shiny and several neutral colors, one structured light pattern would not enough to get the correct segmentation and right decoding label. This paper aims to solve the incorrectness by adding the patterns into surface object. The selective pattern is based on De Bruijn Hybrid pattern from Pages and Salvi et al. The results have shown that the proposed method got more accuracy when compare to one shot pattern.
