Three-dimensional indoor navigation scene generation method and device, electronic equipment and storage medium

Abstract

The invention provides a three-dimensional indoor navigation scene generation method and device, electronic equipment and a storage medium, and relates to the technical field of indoor navigation. According to the specific implementation scheme, the method comprises the steps of performing topology analysis correction on a first element of an indoor space to obtain an effective surface domain of each layer; extracting a geometric center point of a second element of the indoor space as a navigation key node of each layer; obtaining a channel region of each layer based on the topological adjacency relation between the effective surface domain and the navigation key node; extracting a center line from the channel area, and generating an indoor navigation road network of each layer in combination with the navigation key points; generating a multi-layer navigation road network in combination with the indoor navigation road network and the communication area data between the layers; and combining the multi-layer navigation road network with a three-dimensional indoor model to generate a three-dimensional indoor navigation scene. By adopting the embodiment of the invention, the three-dimensional navigation scene can be quickly and accurately generated in real time based on the indoor space digital data, the cost is saved, and the experience feeling of a user is improved.

Description

technical field [0001] The present application relates to the technical field of indoor navigation, and in particular to a method, device, electronic device and storage medium for generating a three-dimensional indoor navigation scene. Background technique [0002] In recent years, with the rise of smart cities and new infrastructure, various convenient and intelligent urban services have emerged. Among them, urban indoor and outdoor integrated location navigation services that are closely related to people's life and travel have received more and more attention. At present, outdoor positioning and navigation technology and products are relatively mature, which can basically meet people's travel needs. However, people are rarely able to enjoy satisfactory location navigation services indoors, especially with the emergence of various large shopping malls, complex buildings, airports, etc. in cities, people's demand for indoor navigation location services is becoming stronger ...

However, people are rarely able to enjoy satisfactory location navigation services indoors, especially with the emergence of various large shopping malls, complex buildings, airports, etc. in cities, people's demand for indoor navigation location services is becoming stronger and stronger

[0003] In the existing technology, indoor navigation is usually two-dimensional, which is not intuitive enough, and the navigation experience is not good; in the research on the construction of three-dimensional indoor navigation scenes, BIM or laser scanning methods are used to obtain indoor navigation data, although Better indoor data quality can be obtained, but for general buildings, the basic data of BIM and laser scanning are usually not available, and it needs to be acquired again, and the componentized building information constructed by BIM is relatively fine and the amount of data is huge. The proportion of data information that satisfies the production of mass indoor navigation scenarios is relatively small; the data cost of using lidar equipment to scan indoors is relatively high, and the follow-up needs more data processing work, which is not suitable for large-scale promotion
