This paper describes a stereo-based multi-camera system for complete 3-D information extraction and surface reconstruction of objects in a robot workspace. The system consists of N number of cameras arranged in an N/2 number of periodic stereo pair structure. The common area of a camera pair and the number of cameras are determined based on a linear camera model and a calibration procedure that reguires only three known world points. The construction of the structural description is performed in two stages: (i) the 3-D data from different perspectives are inferred independently using a periodic stereo structure, and (ii) the extracted information from neighboring camera pairs are integrated to reconstruct the complete surface of the object.
