Abstract
Provided are an indoor positioning method of a positioning apparatus using a particle filter based on an RSSI includes initializing a particle in a base map corresponding to a target space for positioning, measuring a first distance value between a terminal and a beacon and a second distance value between the particle and the beacon, calculating a weight of the particle by comparing the first distance value and the second distance value, updating a previous weight of the particle based on the weight and resampling the particle, deriving location estimation coordinates of the terminal if the resampling has been performed as many as a given number of times, and moving the particle to a given point in the target space and repeatedly measuring the first distance value and the second distance value again.
