description An environment building method of virtual reality for collision simulation comprises the steps of firstly, installing a non-contact scanning instrument on a vehicle; scanning artificial building facilities and landscape facilities of city blocks by the non-contact scanner; obtaining modulated images of the city blocks by an image acquisition module of a system; generating three-dimensional graphic images of the city blocks, and displaying the images in a graphic display terminal; obtaining a space coordinate of point cloud data of the city blocks by a digital recognition algorithm; converting the point cloud data to grid data format used for finite element calculation; combining the information recorded by a weather website and finite element grid data, thus obtaining simulation model environment data under the weather conditions at that time, wherein the simulation model environment data is taken as the environment factor condition for finite element analysis and simulation analysis.
