Researches On The Three Dimensional Protruding Surface Reconstruction Based On Grid Projection

Along with rising development of compute technology, the application of compute is extended widely, especially on the application of three dimension which developed rapidly in the last decade. Now compute is applied broadly in the areas of aspect design, video facture etc. It's a major subject in the area of three dimensional application that how to input the model of a real object to the computer which is also known as the three dimensional surface reconstruction.The article based on four layers of theories: the principle, the structure, the realization and the verity analysis. The article described the principle of the three dimensional protruding surface reconstruction.system which based on grid projection, how to build the system, the concrete process realization and demonstrated the utility value of the system through the verity analysis.The creative points of the article are as follows:The arithmetic of picking up the nodes of the grid by using Matlab;The arithmetic of creating the curves of the grid by using Matlab;Picking up the height info of the three dimensional surface from two dimensional plane based on the arithmetics hereinbefore, and reconstructing the three dimensional surface.Getting depth information through processing a single image and fitting the up/down surface through the mold.
