Parking space level navigation system based on indoor low-precision positioning

Abstract

The invention belongs to the technical field of positioning, and discloses a parking space level navigation system based on indoor low-precision positioning. The system comprises an information acquisition module, an image acquisition module, a sensing module, a central control module, a verification module, a positioning module, a distance calculation module, a parking space selection module, a three-dimensional map construction module and a navigation module. According to the parking space level navigation system disclosed by the invention, the vehicle owner can be intuitively guided by constructing the three-dimensional map, so that the vehicle owner can more accurately grasp the condition of the parking lot or the parking space; parking space positioning is carried out based on an indoor positioning method, so that parking space positioning can be accurately carried out; information of a parking lot or a parking garage can be obtained and processed, so that navigation can be more accurately and visually carried out on a user; and information provided by on-site monitoring is obtained, a map and a satellite positioning function of a navigation system are not needed, congenital defects existing in the map and the satellite positioning function are avoided, and accurate navigation of the parking space is realized.

Description

technical field [0001] The invention belongs to the technical field of positioning, in particular to a parking space-level navigation system based on indoor low-precision positioning. Background technique [0002] At present: In the process of driving and traveling, the parking problem has always been one of the problems that plague the majority of car owners. In order to solve the parking problem, it has been proposed in the prior art to set up parking guidance electronic screens on the roadside, and put the remaining parking spaces in the surrounding parking lots in real time on the electronic screens to guide vehicles into parking lots with vacant parking spaces. However, most of the existing parking garages are located underground, and the technology of positioning parking spaces using conventional positioning methods cannot be applied to underground parking garages. Empty parking spaces often need to be searched for a long time in the parking lot. At the same time, whe...

AI Technical Summary

Problems solved by technology

However, most of the existing parking garages are located underground, and the technology of positioning parking spaces using conventional positioning methods cannot be applied to underground parking garages. Empty parking spaces often need to be searched for a long time in the parking lot. At the same time, when the parking lot has a large area, a complex building structure, and a large number of parking spaces, it is difficult for the owner to find a parking space and park for the owner only through the above-mentioned simple parking guidance information. The process has brought inconvenience

[0003] Through the above analysis, the problems and defects of the existing technology are: the positioning and navigation of the existing parking space navigation system is inaccurate, and the navigation wastes a lot of time, is not intuitive, and cannot perform parking space navigation well.
