【Abstract】 a novel system based on the stereo vision and the grid raster projection to reconstruct the three dimensional surface is present. Combining the passive binocular vision principle with the active non-structure projection through a grid raster, The system can avoid the faults in the common system based on the stereo vision, such as the computing complexity, time consuming, image and mismatching. The image matching algorithm from coarseness to precision for the grid stereo images in the system ensures the efficiency. The system structure and the flow chart are discussed in detail. The experimental results prove that the system can achieve the reconstruction for the 3D surface efficiently, especially for the freedom smooth 3D surface without the typical feature. The simple structure, the easy manipulation, and the speediness are also the merits of the system.更多还原
