针对试验中如何测量飞机上某相对运动构件的空间三维坐标的问题,提出了基于飞机惯导数据方法和基于机载视频图像方法。基于飞机惯导数据方法利用经纬仪跟踪飞机上相对运动构件,获取它的方位角A和俯仰角E,并利用飞机的轨迹数据与惯导数据得到运动构件的轨迹,该方法适用于飞机进近段运动构件的轨迹测量;基于机载视频图像方法同样利用光电经纬仪跟踪相对运动构件获取A与E,并综合机载相机视频数据计算出运动构件的轨迹,它适用于飞机道面段运动构件的轨迹测量;最后,提出了一种新的数据融合方法解决了轨迹的平滑问题,实际飞行试验表明了该方法的实用性和有效性。
Aiming at the problem of how to measure the three-dimensional coordinates of the spacecraft’s relative motion component in the experiment, an aircraft-based INS data method and an airborne video image method are proposed. Based on the aircraft inertial data method, the relative motion component of the aircraft is tracked by the theodolite to obtain its azimuth angle A and elevation angle E. The trajectory of the moving component is obtained by using the aircraft trajectory data and the inertial navigation data. This method is suitable for the approach of aircraft approach section Based on the on-board video image method, the optical theodolite is also used to track the relative motion components to acquire A and E, and the moving camera component data is calculated based on the video data of the airborne camera. It is suitable for the trajectory of the moving component Finally, a new data fusion method is proposed to solve the problem of trajectory smoothness. Actual flight tests show the practicability and effectiveness of this method.
