Web5 Dec 2016 · Significance. Particle filtering is an essential tool for the estimation and prediction of complex systems including non-Gaussian features. A class of particle filters, clustered particle filters, is introduced for high-dimensional dynamical systems such as geophysical systems. The proposed method uses relatively few particles compared with … WebThis approach uses a particle filter in which each particle carries an individual map of the environment. Accordingly, a key question is how to reduce the number of particles. We present adaptive techniques to reduce the number of particles in a Rao- Blackwellized particle filter for learning grid maps. We propose an approach to compute an ...

WebThe project aims to implement the structure of mapping and localization in an indoor environment using information from IMU and Lidar range sensors.
