Extended Object Tracking Using Monte Carlo Methods
Abstract-- This paper addresses the problem of tracking extended objects, such as ships or a convoy of vehicles moving in urban environment. Two Monte Carlo techniques for extended object tracking are proposed: an Interacting Multiple Model Data Augmentation (IMM-DA) algorithm and a modified version of the Mixture Kalman Filter (MKF) of Chen and Liu [1], Mixture Kalman Filter modified (MKFm). The DA technique with finite mixtures estimates the object extent parameters, whereas an IMM filter estimates the kinematic states (position and speed) of the manoeuvring object. Next, the system model is formulated in a Partially Conditional Dynamic Linear (PCDL) form. This affords us to propose two latent indicator variables characterising, respectively, the motion mode and object size. Then a MKFm is developed with the PCDL model. The IMM-DA and the MKFm performance is compared with a combined IMM-Particle Filter (IMM-PF) algorithm with respect to accuracy and computational complexity. The most...
