The invention discloses a micro-map reverse vehicle finding method based on WiFi positioning. The method comprises the following steps that firstly, a map is drawn, wherein information of buildings in a parking lot is collected, the map is drawn and provided with longitudes and latitudes, and then the map is converted into a map database stored in a parking lot server; secondly, a WiFI fingerprint database is established; thirdly, stall memorizing is carried out, wherein a positioning client side is used for reading the map data of the parking lot server, after a vehicle is parked, the current position of the vehicle is obtained through WiFi fingerprint positioning, and then the current stall information is stored into a local database of the positioning client side; fourthly, reverse vehicle finding is carried out, wherein the current position of a user is obtained through the positioning client side and WiFi fingerprint positioning, the stored stall information is read from the local database of the positioning client side, the shortest path is found through Dijkstra, and the navigation path is displayed on the map of the positioning client side. By means of the WiFi fingerprint positioning method, the parking position is accurately positioned, and the parked vehicle is quickly found through the map navigation path.
