In recent years，with the improvement of people’s live standard, people’s demand for the service of the indoor location is increasing which makes the research of indoor location technology become a hot issue.Wireless network anchor nodes deployed uneven,and density was small,the traditional localization algorithms had not considered Received Signal Strength Indicator(RSSI) news from anchor node,location accuracy was low.In order to improve the location accuracy,this paper proposed a location method based on the RSSI.In addition, through the combination of algorithm and inertial navigation unit and Building Information Modeling(BIM) technology, This method realizes the improvement of traditional centroid localization algorithm, improves the precision of indoor location, and realizes the 3D visualization of location information in architectural model.
