Underground garage parking space positioning and navigation method based on mixed beacon flow

Abstract

The invention discloses a beacon flow positioning and navigation method for deploying a Bluetooth beacon by using an underground garage and performing beacon confirmation in combination with a manualbeacon. The positioning and navigation during a vehicle driving or user walking process in the underground garage are realized by using a mobile phone navigation App and background service software. The method comprises a navigation map generation method based on distinction unit division dedicated to underground garage navigation. By decomposing and merging the units of a navigation map, the mapdesign is simplified, and multi-task rapid mapping is achieved. The beacon flow positioning and navigation method disclosed by the invention has the characteristics of simple implementation, low costand high practicability, and can be applied to the fields of indoor vehicle search, indoor navigation and shared parking space rental.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning and navigation, in particular to an underground garage parking space positioning and navigation method based on mixed beacon streams. Background technique [0002] With the expansion of cities, there are more and more large public parking lots and underground garages in large communities. These underground garages are usually laid out regularly, with little visual difference and easy to get lost. Public parking lots have the problem of finding empty parking spaces and parking spaces; when the community’s underground parking spaces are shared and open, there are also problems of finding rental spaces and parking spaces. At present, there is no convenient and practical solution. The current outdoor positioning technology has tended to be perfect, and the use of Beidou, GPS and other systems in the fields of industry, commerce, transportation, and tourism has become mature, but they cannot...

Problems solved by technology

5. Wi-Fi positioning technology; Wi-Fi positioning relying on fingerprint collection is currently a relatively mature indoor positioning and navigation method, which has the advantages of low cost and high accuracy, but in most cases, the fingerprint database is located in indoor buildings. Frequent changes in objects require frequent re-collection of data resulting in increased maintenance burden

However, it is greatly affected by noise and the maintenance cost is also high

[0004] When the above method is used in the navigation application of underground parking spaces, either because of the sensor itself, or because of the difficulty and cost of deployment, or because it is not easy to integrate on the mobile phone, it cannot be as practical as the outdoor GPS navigation application.
