With the rapid development of three-dimensional computer technology and digital imaging software and hardware technology, the three-dimensional surface reconstruction has got more and more people's attention, and more and more widespread applications. The three-dimensional surface reconstruction can be summarized into the accessing of three-dimensional point cloud data, the 3D point cloud data processing, finally complete the three-dimensional reconstruction of the surface based on the point cloud data. As the first step in the process of three-dimensional surface reconstruction, the 3-D point cloud data collection is the sources of rebuilding the model, whether it's accuracy or not directly related to the precision of the results of reconstruction. On the other hand, known point cloud data, to achieve surface reconstruction, which involves computational geometry, topology, and computer graphics, and other fields of knowledge. Therefore, the three-dimensional reconstruction of the surface is of great theoretical study and practical application of significance.Among the starting point is the use of simple equipment that ordinary optical camera or a camera, in relatively simple and routine conditions of the background environment, use microcomputer to complete 3D surface reconstruction rapidly. Main purpose is to build three-dimensional surface of the body's reconstruction model, with a focus on point cloud data on the principle of access and access to the process. Its main tasks are the following.First of all. Based on the use of a single camera (camera) through the objects contour extraction, three-dimensional reconstruction of the surface of the model algorithm principle. Through the outline of objects from image processing, data recovery through the outline of three-dimensional surface contour shape, contour adoption of three-dimensional reconstruction of objects on the surface model.According to the improved algorithm, the analysis of the characteristics of a human model, a model of the human body. According to the breakdown of different models, discussed the different models in three-dimensional surface of the reconstruction process and the characteristics of these three-dimensional model of the surface reconstruction.
