Using Photographed Evacuation Plans to Support MEMS IMU Navigation

In this paper, we present various procedures to support a ZUPT-based MEMS IMU navigation application by available external building models and photographs of evacuation plans. In detail, these are approaches for horizontal alignment of the track using the external building shell, for height correction by stair and elevator detection, for the extraction of the initial position and direction using the photographed plan and for the derivation of coarse indoor models from the plan.
