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.
