Navigation Method, Device and System

A navigation method applied to a mobile terminal, comprising:

• obtaining current position feature information, and sending the current position feature information to a server, so that the server determines a position of an area matching the current position feature information based on the current position feature information and a database stored therein, and takes the position as an initial position, wherein the database is created by the server according to position information corresponding to respective areas and correspondence relationship between identification information of the respective areas and respective feature information, wherein the respective feature information is obtained based on feature images of respective areas and sent to the server, and the feature images of respective areas are acquired by image acquiring devices corresponding to the respective areas;
• and
• receiving a route sent by the server and displaying the route on an electronic map, wherein the route is a route from the initial position to a target position, which is determined by the server after determining a position of one empty area of the areas as the target position based on the position information corresponding to the respective areas and the correspondence relationship between identification information of the respective areas and the respective feature information currently stored in the database.

A navigation system, comprising image acquiring devices installed in respective areas, a server and a mobile terminal,

• wherein the image acquiring devices are used to acquire feature images of corresponding areas;
• the server is used to perform a navigation method comprising:
• receiving current position feature information sent by a mobile terminal, determining a position of an area matching the current position feature information based on the current position feature information and a database stored in the server, and taking the position as an initial position, wherein the database is created by the server according to position information corresponding to respective areas and correspondence relationship between identification information of the respective areas and respective feature information, wherein the respective feature information is obtained based on feature images of respective areas and sent to the server, and the feature images of respective areas are acquired by image acquiring devices corresponding to the respective areas;
• determining a position of one empty area of the areas as a target position based on the position information corresponding to the respective areas and the correspondence relationship between the identification information of the respective areas and the respective feature information currently stored in the database;
• and
• determining a first route from the initial position to the target position, and displaying the first route on an electronic map of the mobile terminal;
• and
• the mobile terminal is used to perform a navigation method comprising:
• obtaining the current position feature information, and sending the current position feature information to the server, so that the server determines the position of the area matching the current position feature information based on the current position feature information and the database stored therein, and takes the position as the initial position;
• and
• receiving a route sent by the server and displaying the route on the electronic map, wherein the route is a route from the initial position to the target position, which is determined by the server after determining the position of one empty area of the areas as the target position based on the position information corresponding to the respective areas and the correspondence relationship between identification information of the respective areas and the respective feature information currently stored in the database.
