Indoor Navigation The SLAM approach of mobile robots can be used for pedestrians (visually impaired and blind) adapted to specific movement conditions. Pedestrians have a much more complex odometry than mobile robots. They differ with respect to the type of movements and the involved degrees of freedom. The laser scanner position with mobile robots is fixed relative to the surface [11]. This cannot be guaranteed for pedestrians. Furthermore, the measures of the human body are individual for each person, as is motion. Thus, the challenge is to extract the odometry for each pedestrian and to obtain stabilized laser scanner data.
