Three-dimensional Date Reconstruction and Navigation of Complex Scene in Virtual Environment

Abstract

This Targeting to the complexity and large amount of 3D(three-dimensional) reconstruction of complex scene in virtual environment, Firstly, The 3D data acquisition and conversion principle, scene modeling and texture mapping method were described. Secondly, the geometric modeling and image fusion method was presented. Thirdly, the reconstruction mathematical model of image based on entropy variation were introduced, and then data compression algorithm to reduce the number of the entity grid was given. Besides, the intricate and fine animal wood carving model on the roof was an example, which was optimized and reconstructed. At last, a classical Chinese architecture was used as a prototype for the fusion modeling and optimization, and merging with virtual software a 3D reconstruction of classical architecture and the scene Navigation system in virtual environment was developed with VC++.
