( b , s )-BCSL : Structured Light Color Boundary Coding for 3 D Photography

In this paper we present (b, s)-BCSL, a new coded structured light method for 3D photography. It employs a sequence of complementary color stripe patterns to define correspondences within a camera/projector shape acquisition system. Unique codes are associated with the boundaries of successive stripes in time. The use of color fully exploits current imaging hardware and makes possible an effective trade-off between spatial and temporal coherence. Furthermore, alternating complementary colors completely eliminates photometric restrictions.
