Abstract

The invention discloses a mobile auxiliary indoor positioning method and a mobile auxiliary indoor positioning system based on a smart phone platform. For the mobile auxiliary indoor positioning method and the mobile auxiliary indoor positioning system, the position of a user in a room is located by establishing a fingerprint database and a mobile database. The positioning method comprises the following steps of: after receiving a positioning request sent by a user, collecting RSSI (received signal strength indicator) fingerprints of the position of the user according to the positioning request, matching the RSSI fingerprints with RSSI fingerprints in the fingerprint database, and returning a set containing candidate positions with fixed quantity according to the matching result; according to data in the mobile data, the information of moving information and moving distance of the user, calculating the candidate positions in the set containing the candidate positions with the fixed quantity as the probability of the position of the user, so as to obtain the position of the user. Compared with the traditional indoor positioning method, the mobile auxiliary indoor positioning and the mobile auxiliary indoor positioning system have the advantages of high positioning precision and small maximum error, and can continuously and accurately positioning in a positioning process in real time.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a mobile-assisted indoor positioning method and system based on a smart phone platform. Background technique [0002] With the increasing maturity of communication and mobile computing, context awareness has become an essential part of many ubiquitous computing applications, where location information is the most important. Reliable and accurate location information enables users to obtain and share promotional information, search for events of interest around them, and experience a variety of social and entertainment methods. On the other hand, the substantial improvement of the sensor manufacturing process has also profoundly reformed the communication and intercommunication between human beings and the physical world. Various types of small sensors have been integrated into many handheld devices, such as smartphones, which are increasingly common today, enabling ne...
