Abstract
A terminal positioning method is applicable in a positioning system having at least an image acquisition apparatus, and the method includes: judging whether a positioning request message sent from a terminal is received; acquiring a current position feature of the terminal when the positioning request message sent from the terminal is received; calculating current position data of the terminal according to the position feature; generating position information according to the position data; and sending the position information to the terminal. In this way, the terminal itself does not need to calculate the current position, thus reducing computational burden on the terminal, which facilitates achieving of fast navigation of the terminal.
Claims12
A terminal positioning method applicable in a positioning system, the positioning system at least comprising an image acquisition apparatus, the terminal positioning method comprising:
- judging whether a positioning request message sent from a terminal is received;
- acquiring a current position feature of the terminal when the positioning request message sent from the terminal is received;
- calculating current position data of the terminal according to the position feature;
- generating position information according to the position data;
- and
- sending the position information to the terminal.
A terminal positioning method applicable in a mobile terminal or an electronic device, comprising:
- sending a positioning request message;
- and
- receiving position information, wherein the position information is generated in a way that when a server receives the positioning request message sent from the terminal, the server acquires a current position feature of the terminal, calculates current position data of the terminal according to the position feature, and generates the position information according to the position data.
A terminal positioning system, comprising:
- a judgment unit, adapted to judge whether a positioning request message sent from a terminal is received;
- a feature acquisition unit, adapted to acquire a current position feature of the terminal when the positioning request message sent from the terminal is received;
- a calculation unit, adapted to calculate current position data of the terminal according to the position feature;
- a position information generation unit, adapted to generate position information according to the position data;
- and
- a sending unit, adapted to send the position information to the terminal.
