3-D reconstruction based on structured light of composite colorful stripes

In order to improve the precision of 3D reconstruction, a new composite coding way based on structure light is proposed. In this paper, color stripe pattern is used as basic coding element and intensity properties are introduced for every color stripes to design coding pattern. This coding pattern can be used to extract stripe peak and edge information on sub-pixel level. In the reconstruction we use both peak-based reconstruction and edge-based reconstruction. Experimental results show that the combination of two kinds of reconstruction style can ensure higher reconstruction accuracy.
