sensor fusion with particle filters

A distributed particle-PHD filter using arithmetic-average ...

Second scenario—Particle-based and GM-based local PHD filters. Next, we study a heterogeneous network where the eight nonlinear sensor nodes use a particle-based local PHD filter and the eight linear sensor nodes use a GM-based local PHD filter , (briefly referred to as GM-PHD filter). The sensor network topology and the target trajectories are as before (see Fig. 2).

GPS/INS - Wikipedia

In general, GPS/INS sensor fusion is a nonlinear filtering problem, which is commonly approached using the extended Kalman filter (EKF) or the unscented Kalman filter (UKF). The use of these two filters for GPS/INS has been compared in various sources, including a detailed sensitivity analysis.

An Improved Unscented Particle Filter Approach for Multi ...

Abstract. In this paper, a new approach of multi-sensor fusion algorithm based on the improved unscented particle filter (IUPF) and a new multi-sensor distributed fusion model are proposed. Additionally, we employ a novel multi-target tracking algorithm that combines the joint probabilistic data association (JPDA) algorithm and the IUPF algorithm.

Localization — PythonRobotics documentation

Particle filter localization¶ This is a sensor fusion localization with Particle Filter(PF). The blue line is true trajectory, the black line is dead reckoning trajectory, and the red line is estimated trajectory with PF. It is assumed that the robot can measure a distance from landmarks (RFID). This measurements are used for PF localization. Ref:

sensor fusion with particle filters

The paper examines the problem of dynamic ship positioning with the use of Kalman Filter- and Particle Filter-based sensor fusion algorithms. The proposed approach enables to estimate accurately the ship's state vector by fusing the vessel's position and heading measurements coming from on-board sensors together with distance measurements coming from sensors located at the coast ( radar).
