Abstract: Traditional Monte Carlo filter for target tracking has the problem of sample barren, which leads to samples degraded directly. To solve this problem, an improved Monte Carlo filter has been proposed. During the initial stage, the samples are built based on vision method, more samples which are near the center are got, and fewer samples which are far from the center are got. During the samples transmission process, half of the samples are re-sampled. The other half of samples are transmitted directly. Experimental results show that this method deals with sample degraded problem well.
