摘　　要：根据靶面上人为设置的多个标识点之间的几何关系随靶面姿态的变化而变化的特性,设计出一种快速准确的光束-靶面入射角测量算法,满足光束到靶入射角测量的任务需求。在提取靶面已知特征点的基础上,采用光学传感器的内参数,测量出光束到靶入射角,此算法以非接触的方式完成光束到靶入射角的测量。为了验证算法的有效性和实用性,开展了仿真实验,结果表明该方法具有较高稳定性和可靠性。A fast and accurate ray-target face incident angle measurement algorithm is proposed to meet the requirement of practical ray-target face incident angle measurement mission. Since the geometry distribution relationship among the advanced-set feature points changes along with the pose transformation, ray-target face incident angle could be measured in a non-contact way. On the basis of drawing target face identification points, ray-target face incident angles are calculated using optical sensor internal parameters. Both simulations and experiments are conducted to prove the effectiveness and practicability of the proposed algorithm. The results confirm the high stability and reliability of the proposed method.
