【摘要】：靶场现有落点坐标测试设备大多数基于地面观测平台,存在通视要求的局限性,无法及时预测落点概略坐标,且对于连发密集型射击试验无法区分弹序。针对该问题,根据物点与像点的几何位置关系,提出了3种将观测平台设置为空中的无人机弹丸落点测量方法:内差法、距离比例法以及求解姿态角法。介绍了3种算法的基本原理和数学模型,然后结合模拟试验现场的测试数据对3种方法进行了验证,最后计算出满足要求所需要的相机最低技术指标。实验结果表明:内差法和比例法测量精度低于3m,求解姿态角法的精度小于0.3m。
[Abstract]:Most of the existing test equipment of landing point coordinate is based on the ground observation platform, which has the limitation of common view requirement, and it can not predict the general coordinates of landing point in time. And for the continuous firing intensive shooting test can not distinguish the order of the projectile. In order to solve this problem, according to the geometric position relationship between the object point and the image point. This paper presents three methods to measure the impact point of UAV projectiles: the method of inner difference, the method of distance proportion and the method of solving attitude angle. The basic principle and mathematical model of the three algorithms are introduced. Then combined with the test data of the simulation test site, the three methods were verified. The experimental results show that the precision of the internal difference method and the proportional method is less than 3 m, and the precision of the attitude angle method is less than 0.3 m.

【正文快照】： 引言近年来,随着无人机技术的快速发展,加之成像系统的同轴实现,使无人机快速测量弹丸落点坐标成为可能。自19世纪中叶至今,摄影测量已发展160余年,作为测绘学科的一个分支,主要用于绘制地形图[1],用在弹丸落点坐标测试尚属空白。靶场现有的落点坐标测试设备大多基于地面观测，
