Hybrid optical system for three-dimensional shape acquisition

Hybrid concepts are often used to improve existing methods in many fields. We developed a hybrid optical system that consists of multiple color cameras and one depth camera to make up the concavity problem of the visual hull construction. The heterogeneous data from the color cameras and the depth camera is fused in an effective way. The experimental results show that the proposed hybrid system can reconstruct concave objects successfully by combining the visual hull and the depth data. (C) 2013 Optical Society of America
