摘　　要：炮弹炸点坐标检测是射击偏差校正的主要依据和毁伤效果评估的核心环节,为实时检测炮弹炸点三维坐标,提出一种基于退化共线方程与数字高程模型的炮弹炸点坐标检测方法。以多旋翼无人机作为空中监测平台,实时捕获炮弹落区场景,分割炮弹炸点图像并计算其图像坐标。通过共线方程原理建立炮弹炸点图像坐标与三维坐标关系式,并结合炮弹落区数字高程模型,进行匹配运算,实现炮弹炸点的实时检测输出。在实弹试验条件不足情况下,构建了炮弹炸点坐标检测仿真系统,进行单炮射击、分段射击与重叠射击仿真试验,验证了炮弹炸点坐标解算方法的有效性。The detection of artillery shell burst points not only serves as the basis for fire adjustment,but the key for battle damage assessment.In order to accurately detect the three-dimensional coordinates of the artillery shell burst point,a detection method was proposed based on the degenerate colli-near equation and digital height model.A multi-rotor UAV was used as the aerial monitoring platform for the impacting area in real-time.Images of burst points were divided and their coordinates calcula-ted.The relation between burst point image coordinates and three-dimensional coordinates was established on the basis of the collinear equation principle.Taking into account the digital height model of the impacting area,matching operations were performed to realize the real time detection and output of burst points.In the case of insufficient test conditions,a simulation system for the detection of burst point coordinates was constructed.And simulated experiments of single gun firing,segmented firing and overlapping firing were carried out to verify the effectiveness of the burst point calculation methods.
