摘　　要：针对复杂环境下威胁目标攻击场景,基于实际目标可见光图像特征,提出一种目标着落姿态计算方法。通过Roberts算子和Hough变换构建目标图像特征提取模型和目标中轴线确定模型;基于双目交会理论,确定中轴线关键点位置信息,基于三角形理论建立目标姿态角求取方法。通过仿真案例分析表明,所提出的目标着落姿态计算方法可有效提取目标特征,并解算出目标着落姿态角,具备较好的光学测量图像适应性。A target landing posture calculation method is proposed based on the visible light image features of actual threat tar⁃gets in complex threat target attack scenarios.A feature extraction model for target images and a model for determining the target ax⁃is are constructed through Roberts operator and Hough transform.The position information of key points on the central axis is deter⁃mined based on the theory of binocular intersection,and a method for obtaining the target attitude angle is established based on the triangle theory.Through the simulation case analysis,it is shown that the proposed target landing attitude calculation method can ef⁃fectively extract target features and calculate the target landing attitude angle,which has good adaptability to optical measurement images.
