The research about modeling technology of irregular virtual reality scene based on point cloud data

Virtual reality takes full advantage of computer technology, multi-media technology, multi-sensors technology, network technology and so on to set up a senior computer interface between human and computer whose characters are immersion, interaction and conception. Virtual reality is a composition of various technologies, among which is an environment modelling technology,that is the establish of virtual environment, who is the most critical part of the effect reality of virtual reality. In the regular scene of virtual reality. We capture three-dimensional data to form model easily through traditional surveying methods, but as for irregular scene, traditional surveying methods appear not enough. We utilize 3D laser scanning technology to capture the surface sample points of real scene,that are point cloud data, in which way we can restructure any complex scene non-contactedly, quickly and high-accurately to solve the problem of irregular scene effectively.
