摘要
中轴线法是靶场试验中常用的目标三维姿态测量方法,但该方法求出的俯仰角和偏航角所描述的目标姿态可能与目标实际情况相异,必须进行人工修正。提出一种自动对姿态判读结果进行修正的方法,将目标共线方程与中轴线方程联立求解,可快速地求出角度修正量。实验证明该方法可对中轴线法求解结果进行自动修正,得到正确的目标三维姿态角,提高了姿态判读的速度和可靠性。
The axes method is a general method for measuring object＇s 3D pose, but the pitching angle and yawing angle calculated could not be fit for the real situation, which should be corrected manually afterwards. An automatic method for correcting these angles is proposed here, the collinear equations and the axes equations are used for computing the correction of angles. Experiment results show that the 3D pose angles are corrected automatically and the true pose angels of target are gained, the speed and reliability of interpretation are improved consequently.
