Clustering of divergent multi-line structured light stripes based on structural constraint

Aiming at the confusion between multi-line structured light stripes in the 3D measurement system based on divergent multi-line structured light projection, an effective clustering method of multi-line structured light stripes based on structural constraint is proposed in this paper. The light stripes are numbered, and the light stripe image collected by CCD camera are divided into regions. According to the formula proposed in this paper, the region parameters are calculated, and the number of each light stripe is recognized to realize the clustering of line structured light stripe. Experimental results show that this method effectively avoided the confusion between light stripes.
