摘要
多飞行目标的跟踪应用广泛,在靶场中需要对多飞行目标进行跟踪监测时,要排除目标所受的各种干扰因素,当多飞行目标之间出现相互运动时,为保证判断目标击中的准确性,需要对多飞行目标航迹达到稳定保持的测量。因此,系统以靶场中多飞行目标为跟踪对象,着重研究多飞行目标序号保持不变问题。通过不同检测方法对目标的特征提取效果进行对比,并且将多参数的数据关联算法应用于系统的多目标跟踪中,验证得出,在背景均方差MSE介于4.0~5.0之间的情况下,当目标数量多达12个时,其目标序号保持的准确度比PDA算法提高23.29%。
The tracking of multiple flying targets is widely used. When it is necessary to track and monitor multiple flying targets in the shooting range,it is necessary to eliminate all kinds of interference factors on the targets. When multiple flying targets move with each other,in order to ensure the accuracy of judging the target hitting,it is necessary to measure the track of multiple flying targets stably. Therefore,the system takes multiple flight targets in the range as the tracking object,and focuses on the problem of keeping the serial number of multiple flight targets unchanged. Through the comparison of different detection methods on the target feature extraction effect,and the multi parameter data association algorithm is applied to the multi-target tracking of the system. It is verified that when the background mean square deviation is between 4.0 and 5.0,when the number of targets is up to 12,the accuracy of the target number keeping is 23.29% higher than that of the PDA algorithm.
