摘要
研究战场中对敌方目标车辆进行准确定位,可提高战场生存率和战争的胜率。利用传统的GPS定位方法进行敌方目标定位的过程中,由于信号极易受到敌方电磁干扰信号的干扰,从而降低了定位精度。为解决上述问题,提出一种采用图像非均匀映射的无源定位观测方法。利用红外焦平面阵列进行敌方目标车辆成像,对目标车辆图像序列的行驶轨迹分析结果建立目标车辆图像的非均匀性映射模型,消除电磁干扰带来的影响。利用图像中所有像元点在时间轴上发生的拐点图的运动估计最终完成目标车辆的运动估计,从而实现了目标车辆的准确定位跟踪。实验结果表明,利用改进算法能够有效提高目标车辆的定位精度。
Research on the accurate location of enemy target vehicle in battlefield can improve the survival rate and winning rate in battlefield. In the paper, a passive location observation method based on image non - uniformed mapping was proposed. Infrared focal - plane array was used to make enemy target vehicle imaging. And for the traveling track analysis results of the image sequence of target vehicle, the non - uniformed mapping model of target vehicle image was established, to eliminate the effects of electromagnetic interference. Using the motion of the inflection point figure of all pixel points in the image occurred on the timeline completed the motion estimation of target vehicle finally, so as to realize the accurate location and tracking of target vehicle. The experimental results show that using the improved algorithm can effectively increase the accuracy of target vehicle location.
