| Abstract: | This paper presents a tracking method with high accuracy for moving blob target. The measurement errors of position and shift of target centroid between consecutive images are analysed.An improved filtering model is proposed to suppress the influence of intensity noise and sampling error. And' tracking accuracy is promoted. |
