WiFi-Direct-Based indoor positioning method and system

The invention relates to a WiFi-Direct-Based indoor positioning method and system. The system comprises an intelligent terminal and a server, wherein the server is used for receiving the ID (identity) information of indoor WiFi-Direct nodes which the intelligent terminal can connect, matching the ID information with a preset ID information-position database to obtain the position information corresponding to the ID information, and performing indoor positioning on the intelligent terminal through the position of the position information in a corresponding indoor map. According to the WiFi-Direct-Based indoor positioning method, the intelligent terminal searches for and transmitted available preset WiFi-Direct nodes to the server on the basis of the WiFi-Direct technology, and the server determines the position information of the intelligent terminal according to the ID information of the received WiFi-Direct nodes to rapidly position the indoor position of the intelligent terminal, so that indoor positioning accuracy and user experience can be enhanced.
