Abstract


With the rapid development of computer technology as well as three-dimensional digital imaging hardware and software technology , three-dimensional surface reconstruction technique more and more attention , more and more extensive . The three - dimensional surface reconstruction technique can be summed to obtain a three-dimensional point cloud data , the 3D point cloud data processing based on point cloud data to complete the three-dimensional surface reconstruction . 3D point cloud data collected as the first step of the three-dimensional surface reconstruction , the entire process of rebuilding data sources, and its accuracy is directly related to the reconstruction of the accuracy of the results . In the case of known point cloud data surface reconstruction relates to the calculation of the geometry, topology, computer graphics and other areas of knowledge . Therefore, the study of three-dimensional surface reconstruction has the significance of the major theoretical research significance and practical applications . This article is based on the use of common equipment , that the ordinary optical camera or the camera , under the usual conditions and relatively simple context , the use of micro-computer quickly and accurately complete the three-dimensional surface reconstruction . The main purpose is to rebuild the surface of the three-dimensional model of the human body , with emphasis on the principle of point cloud data , access to the process and the surface of the human body three-dimensional reconstruction . The main work includes the following sections . The first discusses the use of the object contour extraction based on a single camera ( camera ) through the reconstruction of three-dimensional surface model algorithm principle . Then the algorithm to be modified , making it suitable for the reconstruction equipment and environment as used herein and through the experimental verification of the correctness of the algorithm , the experimental results are given . Through experiments , and further found a problem in the algorithm , the algorithm further improvement of possible errors and the error of the algorithm and the experiment cited qualitative discussion . According to the modified algorithm , the analysis of the characteristics of the human body model , to be divided on the human body model . According to the division of the different model , studied the characteristics of the different models in the three-dimensional surface reconstruction process and model the three-dimensional surface reconstruction .
