| 摘 要： | 介绍了一种以目标形心位置和帧间位移测量的多目标跟踪方法。当目标在传感器视场中交叉运动,图像相互重叠时,得到由两个目标形心位置线性组合的融合后的图象测量方程。图像的重叠导致状态估值误差的相互依赖性,利用联合测量耦合滤波器对两个目标进行状态估值,并提出了改进的滤波模型。仿真结果表明,该算法能实现对交叉运动目标进行精确跟踪。

| Abstract: | 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. |
