Abstract

The invention relates to the technical field of three-dimensional scene generation, and provides a scene generation method based on indoor three-dimensional modeling and positioning. The scene generation method comprises the steps of: (1) establishing an indoor three-dimensional model; (2) deploying an indoor positioning beacon; (3) generating a robot photographing point position; (4), photographing an indoor panoramic photo; (5), and carrying out automatic patching on an indoor three-dimensional scene. The invention further provides a scene generation system based on indoor three-dimensional modeling and positioning. The scene generation method and the scene generation system have the beneficial effects of constructing indoor building three-dimensional information rapidly in a linkage manner by adopting indoor three-dimensional modeling, indoor positioning, robot, panoramic photographing technologies and the like, generating an indoor positioning point map, selecting a robot photographing point precisely based on the indoor positioning point map, ensuring the rapid and precise generation of the indoor three-dimensional scene, solving the problem that the scene reconstruction precision is not high because the photographing position is selected according to manmade judgment, ensuring the optimal positioning of the photographing position, making the generation of the indoor three-dimensional scene more efficient, being reasonable and feasible in method, and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scene generation, in particular to a scene generation method and system based on indoor three-dimensional modeling and positioning. Background technique [0002] The rapid development of urbanization in my country, the complexity of urban construction and the severe requirements of the information age make urban development need to inject new vitality. The concept of digital city points out the direction for the development of urban informatization in the future. Urban informatization can realize the sharing and comprehensive utilization of urban information, promote the integration of urban information, improve social security, enhance government work functions, and promote the informatization of enterprises and institutions, thereby increasing social productivity and improving human living standards. The 3D digital city can establish a virtual urban geographic information environment a...
