Auxiliary Particle Filter Robot Localization from High-Dimensional Sensor Observations

  title={Auxiliary Particle Filter Robot Localization from High-Dimensional Sensor Observations},
  author={Nikos A. Vlassis and Bas Terwijn and Ben J. A. Kr{\"o}se},
We apply the auxiliary particle filter algorithm of Pitt and Shephard (1999) to the problem of robot localization. To deal with the high-dimensional sensor observations (images) and an unknown observation model, we propose the use of an inverted nonparametric observation model computed by nearest neighbor conditional density estimation. We show that the proposed model can lead to a fully adapted optimal filter, and is able to successfully handle image occlusion and robot kidnap. The proposed… CONTINUE READING
