针对动态目标的三维姿态不断变化，研究了在单站跟踪模式下，如何利用光测手段快速准确地对飞行目标的姿态进行实时定位的问题。在对目标结构有一定先验知识的前提下，提出了一种基于动态目标结构特征的姿态实时定位方法。方法在跟踪闭环的基础上，对光电摄像机实时采集的目标图像进行二维特征提取，并将此二维特征与目标自身的三维结构特征相对应，通过解算对应的数学关系模型，实现对动态目标姿态的实时定位。通过3 dmax建立场景，模拟飞机的动态飞行过程，开展了仿真实验。方法对动态飞机目标姿态定位准确，且每帧定位所需时间不大于0.02 s，处理频率达到50 Hz ，满足了实时性需求。结果表明，该方法对动态目标的姿态实时定位上具有一定的有效性。

As to the change of 3D pose of dynamic target without tags, how to locate the target’s pose on single camera mode rapidly and accurately was researched. On the premise of the knowledge of target’s structure, the method of real-time pose location based on structural feature was proposed. On the basis of tracking steadily, the 2D feature of target in image which was caputured by optical camera was extracted. Corresponding the 3D features of the target with its 2D features in image, the mathmatics mode could be cancluted, and then the pose of dynamic target was located. The simulated experiment was developed with the imitation of airplane’s flight. Applying this method on the imitation flight, the aveage time of processing was less than 0.02 s and the frequency of location was upper than 50 Hz. The experiment results show that this method is effective for pose real-time location of dynamic target.
