Abstract

The invention discloses a user positioning and navigation method and system in a building, comprising the following steps: S1, locating the current location of the user; S2, establishing a layered path network for the building, based on the obtained layered path network, according to the user's current location The location of the user and the destination specified by the user are searched for the path, and the path with the shortest sum of path lengths is used as the path from the user's current location to the user-specified destination; S3, using the PDR positioning algorithm to calculate the user's position during walking in real time Information, and according to the method described in step S2, the path between the user's current location and the destination is updated in real time. By establishing a layered route network for the building, and according to the current location of the user and the destination specified by the user, the route search is carried out according to the situation, and the route is planned hierarchically, so as to realize the route navigation under multiple floors, and the navigation accuracy is high .

Description

technical field [0001] The invention belongs to the technical field of indoor positioning and navigation based on mobile devices, and more specifically relates to a method and system for positioning and navigation of users in a building. Background technique [0002] According to statistics, most people spend more than 70% of their time inside buildings every day, and consumption inside buildings accounts for a higher proportion of overall consumption. At the same time, with the rise of Internet companies, location-based services and applications are developing rapidly, such as Android applications such as Meituan, Ele.me, and Didi Chuxing. Users feel the convenience of outdoor location-based services and applications. For location-based services in buildings demand is also increasing. [0003] In-building navigation can be used for user guidance in large buildings. In large buildings such as railway stations, shopping malls, teaching buildings, and conference centers, due...
