Abstract

The invention relates to a method for generating a three-dimensional road model, which belongs to the field of three-dimensional road modeling. The method comprises the following steps: (1) collecting the data of the center line of a road to obtain the two-dimensional node data of the center line of the road; (2) resolving the structural characteristic of the road and constructing a road model; (3) separating out the node data of the center lines of a common road section and an intersection from the two-dimensional data of the center line of the road; (4) modeling the node data by invoking the road model to generate the characteristic point data of the edges of the common road section and the intersection; (5) connecting each point corresponding to the characteristic point data of the edges to generate a road model of a three-dimensional grid; and (6) sticking a corresponding texture onto the generated road model of the three-dimensional grid according to the attribute data of the road to obtain a three-dimensional solid model of the road. The invention also provides a system for generating the three-dimensional road model. According to the method for generating the three-dimensional road model, which is disclosed by the invention, the three-dimensional road model is generated in a fully automatic way, the manual intervention is avoided, and the modeling efficiency is enhanced.

Description

technical field [0001] The invention belongs to the field of three-dimensional road modeling in virtual reality, in particular to a method and system for generating a three-dimensional road model. Background technique [0002] In many application fields, the traditional two-dimensional (2D) display has become more and more boring, tedious and monotonous, far from satisfying various demands brought about by the progress of the times. The emergence of virtual reality and three-dimensional (3D) technology has revolutionized people's vision. The vivid, realistic and rich virtual reality world brought by 3D technology enables people to observe the real scene of the real world more intuitively on the computer. [0003] In the field of electronic map navigation, traditional two-dimensional maps use "points" and "lines" to abstractly describe the objective world. Although this method can provide the information needed by users simply, quickly and in a timely manner, it also has a ...
