摘　　要：为了解决航空武器对地攻击弹丸终点测量系统的测量精度问题,提出了运用交汇测量法测量目标的瞬间空间位置,并采用多目标动态检测算法完成了在图像序列中同时提取所有动态目标的功能。该算法针对图像中包含较复杂背景情况下,动态目标的提取和位置测量,从而加强了动态目标测量系统的精确性和快速性。经实验证明,系统可正确提取出现在视场中的激光点目标,在检验打击点测量的结果与真值的误差时,图像脱靶量的测量精度优于1pixel,图像脱靶量测量分辨率为0.5pixel。To improve the accuracy of droppoint measurement system when airborneweapon attacks over the ground, this article presented utilizing the intersection measurement method to measure the instantaneous space position of target, and completed the function of pick up all dynamic target in image order by employing multiple target dynamic measurement method. The function was realized what dynamic target collection and position measurement in image which contained complex background, and could improve the accuracy and rapidity of dynamic target measurement system. Experiments testify that the system can pick up the laser target exactly. The measurement accuracy of misses of image is better than ] pixel when detecting the result error of experiment and true-value. The distinguishability of misses of image is 0,5 pixel.
