In the fifth part we describe the procedure of amalgamating target and put emphasis on the research of target tracking method , by building up the moving status of target we can solve the problem of occultation . - - filter is adopted to predict next position of target so we can reduce the range of seeking matched target 在跟踪过程中，着重针对多个运动目标遮掩的情况，设计了基于运动状态的识别和跟踪方法，并利用常系数的kalman滤波器对运动目标的位置进行预测，解决了目标遮挡情况下的识别和跟踪问题。
