Abstract
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.
