With the rapid development of computer science,image process and pattern recognition technologies,people are paying more and more attention on parallel two-eyes-visual system and three-dimension reconstruction.The research has applied in many fields.We study and design a set of two-eyes-visual system to obtain pictures vividly.Cubic-image-depth-map based on two-eye vision technology is the key technique for reconstructing 3D-shapes out of 2D-images.So the quality of depth-map can directly influence the result of three-dimensional-image reconstruction.The depth-map has gained more and more attentions in the field of computer vision.
