Embodiment 1

[0019] A method for building a virtual reality environment for collision simulation is characterized in that it is realized through the following steps:

[0020] S1: First install the non-contact scanning instrument on the driving vehicle;

[0021] S2: Use a non-contact scanning instrument to scan various artificial and natural facilities such as street lamps, guardrails, and flowers in the block;

[0022] S3: After scanning, the image acquisition module obtains the modulated image of the block object; the modulated image is the generated finite element grid image;

[0023] S4: The image generation module generates a three-dimensional graphic image of the block object from the modulated image, and displays it in the graphic display terminal; the three-dimensional graphic image displays the shape characteristics, material properties and spatial position of the block;

[0024] S5: The non-contact scanning instrument obtains the spatial coordinates of the point cloud data of the...

Abstract

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.
