Research On 3D Scanning And Printing Technology Of The Human Body Image

With the continuous development of the progress of the society, science and technology, single traditional manufacturing processing already could not meet the market demand; since the 1980 s, the RP(Rapid Printing) technology has been Rapid development, there appeared the three-dimensional light curing technology, laser sintering technology, binder jet Printing technology, the curvature of the smooth Printing technology, laminated print technology, etc.; At the same time, also emerging in the 3D scanning technology, 3D scanning technology is, by taking the external subject outline information access to the subject space coordinates of point cloud, and then build the topology of the subject, so as to establish a rapid prototyping technology of physical reality model. Traditional manufacturing technology and the combination of RP technology in processing and manufacturing of the future will bring a new revolution to the manufacturing, so the RP technology of 3D scanning technology and printing technology is necessary.Article focuses on the human body image space subdivision algorithm of scattered point cloud data, human face Delaunay triangular grid branch application theory; This paper introduces the spatial point cloud body image mesh bottleneck problems in the branch office, at the same time gave the corresponding solution of the problem. And put forward the infinite spatial point cloud segmentation sample point set approximate a flat two-dimensional point swarm optimization subdivision theory, and gives the core algorithm and display of the process, at the same time the algorithm examples show, the subdivision of human face realistic model is established and deviation analysis, proved the feasibility of the algorithm.The article expounds the physical the importance in the surface reconstruction of point cloud data read integrity; Secondly introduces the point cloud is the basis of physical reality model representation, if consuming less than good point cloud data, no matter how to carry on the point cloud data processing, in the later will appear deviation, he can’t get accurate physical realistic model;The article also focuses on using the block calibration way to lost point cloud to pick up again, and then obtain the loss of the right point in theory of spatial coordinates; At the same time, this chapter also rest on overall another row local process and local to the process of surface mesh display; And the resulting physical reality model deviation analysis.The article also introduces the working principle of SLA printing; And material saving method for the printing craft model in the research, and experimental verification, quantitative data, comparison analysis; Also introduced the curing light as the deformation mechanism of the characteristics, forms of macroscopic deformation and deformation was studied using deformation pump shell of problem.
