GoIn—An accurate 3D indoor navigation framework based on light landmarks

Wireless computer network (WLAN)-based building-level positioning coupled with cellular information is thoroughly investigated in literature. This paper introduces a framework for accurate indoor positioning system (IPS) and navigation, which outperforms known algorithms. The main idea is to use a modified particle filter with weights computed as a function of radio frequency (RF) finger-printing, odometry, visual landmarks, and map constraints....
