Abstract: The particle filter's real-time capability is poor because of a large number of the particles' calculation of the algorithm. Because of the particle filter's characteristics of parallelism, we used OpenMP multithread implementation to derive multiple threads, in order to change the algorithm from the single thread serial implementation to multithread implementation in parallel. In the multiple processors platform, the parallel-computed technology and particle filter algorithm were used to implement the tracking of the moving object. The results show that the method can improve the algorithm's execution speed.
