Choice mechanism of proposal distribution in particle filter

Abstract

Aimed at the inherent deficiency in particle filter, it is important for the choice mechanism of proposal distribution in particle filter. Combined with the up-to-date research and application, key choice mechanisms in current study of proposal distribution are respectively summarized from the aspect of direct choice mechanism, choice mechanism with other filter method, and adaptive choice mechanism. At the same time, the simulations based on single object tracking are implemented to estimate the performance of the different proposal distribution in particle filter. So, the accuracy of the above analyses is verified.
