A New Robust Color Coding Technique for Solving the Correspondence Problem and 3D Reconstruction in Structured Light Systems

Structured light is one of the most appropriate methods for 3D measurement and reconstruction. In this research, a new technique based on the spatial neighborhood coding has been used due to its single pattern feature and the possibility of applying to dynamic surfaces. A color grid pattern coded with De Bruijn sequences has been designed and applied. The implemented correspondence algorithm shows the possibility of solving the matching problem, even in discontinuous and some colorful areas
