Problems solved by technology

However, in modern big cities, there are many buildings such as skyscrapers, commercial buildings and overpasses. If two users are separated by a building, even if they are within the same latitude and longitude range, it is difficult to find each other through the mobile phone positioning function.

Abstract

The present invention provides a positioning method and a positioning server. The positioning method includes: receiving a surrounding real-scene image sent by a requesting user; comparing the surrounding real-scene image with a pre-stored image in a map database, wherein each A pre-stored image corresponds to a location point information; acquire a pre-stored image matching the surrounding real scene image and location point information corresponding to the pre-stored image; generate the site location information of the requesting user according to the location point information; The above-mentioned on-site location information is sent to the target receiving user. The present invention can realize short-distance precise positioning between two or more users.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method and a positioning server. Background technique [0002] GPS (Global Positioning System) positioning technology is mainly used in the positioning of the user's position and the transmission of positioning information. The positioning principle is: the mobile terminal first performs GPS positioning, and after the positioning is successful, the longitude and latitude information is transmitted to the positioning server. The location of the terminal is marked on the map, and then the webpage link of the map is returned to the mobile terminal, and finally the mobile terminal will display the current location of the terminal on the map through the webpage. [0003] Existing positioning methods usually require 2 or 3 base stations, such as figure 1 As shown, base station 1 locates the user's location information through communication with the user, whic...
