Abstract

The invention discloses a three-dimensional map surveying and mapping system. The three-dimensional map surveying and mapping system includes a central processing system, the input end of the centralprocessing system is connected with the output end of the feedback module; the input end of the feedback module is connected with the output end of the three-dimensional processing system; the input end of the three-dimensional processing system is connected with the output end of the data integration module; the input end of the data integration module is connected with the output end of the information acquisition system; the three-dimensional processing system comprises an image processing system, a 3D feature extraction module, a virtual object placement module and a 3D map generation module; the output end of the image processing module is connected with the input end of the three-dimensional feature extraction module, and the output end of the three-dimensional feature extraction module is connected with the input end of the virtual object imbedding module. According to the three-dimensional map surveying and mapping system, the rendering acceleration process can be achieved, thetime spent on three-dimensional model rendering is shortened, and the practicability of the three-dimensional map surveying and mapping system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping systems, in particular to a three-dimensional map surveying and mapping system. Background technique [0002] Three-dimensional electronic map or 3D electronic map is a three-dimensional and abstract description of one or more aspects of the real world or a part of it based on a three-dimensional electronic map database. The way of expression provides users with map retrieval functions such as map query and travel navigation, which not only provides convenience for people's travel, but also enriches the rapid development of computer graphics, 3D simulation technology, virtual reality technology and network communication technology. Two-dimensional electronic maps have been injected with new vitality, and three-dimensional electronic maps carried on the Internet are becoming an important direction for the development of electronic maps. The network three-dimensional electronic map not...
