Abstract
A method and a system for indoor positioning are provided. In the present method, a default positioning weight is defined at first. Then, a plurality of neighboring ranging devices near a target device is obtained from all wireless ranging devices deployed in an indoor space, and a current positioning weight of each of the neighboring ranging devices is calculated. Next, the current positioning weight of each of the neighboring ranging devices is respectively compared with the default positioning weight, so as to obtain a plurality of reference ranging devices from the neighboring ranging devices. After calculating at least one candidate coordinate according to a deploy coordinate of each of the reference ranging devices, a positioned coordinate represents the current location of the target device is estimated according to the at least one candidate coordinate.
