A method for tracking multiple targets based on measurement of target image centroid position and offset from image sequence is presented.When the overlap of target occurs,the resulting centroid mea- surement of distributed image is a single merged measurement which is a linear combination of the centroids of individual targets.The overlap of images also causes a dependance of state estimation errors for two tar- gets.A merged measurement coupled filter is employed for state estimation and an improved filting model is proposed.The silmulation result shows that the method can give precise tracking for crossing targets.
