c ©2012 Springer-Verlag Berlin Heidelberg 2012. The original publication is available at www.springerlink.com. DOI: 10.1007/978-3-642-31534-3 78 By implementing a combination of an activity recognition with a map-supported particle filter we were able to significantly improve the positioning of our navigation system for blind people. The activity recognition recognizes walking forward or backward, or ascending or descending stairs. This knowledge is combined with knowledge from the maps, i.e. the location of stairs. Different implementations of the particle filter were evaluated regarding their ability to compensate for sensor drift.

متن کاملA Robust Framework for Failure Detection and Recovery for Terrain-relative Navigation
Terrain-Relative Navigation (TRN) is an emerging technology used for localization of autonomous underwater vehicles (AUVs). TRN provides a map-relative position estimate for vehicle navigation, and has been demonstrated with meterlevel accuracy. However, in adverse conditions, such as operating over areas of terrain change (i.e. mass transport events) or artifacts of the map-generation process,...
متن کاملParticle filters for positioning, navigation, and tracking
A framework for positioning, navigation, and tracking problems using particle filters (sequential Monte Carlo methods) is developed. It consists of a class of motion models and a general nonlinear measurement equation in position. A general algorithm is presented, which is parsimonious with the particle dimension. It is based on marginalization, enabling a Kalman filter to estimate all position...
