光电经纬仪跟踪飞机3D姿态方法研究

Methods Study of 3D Attitudes for Photoelectric Theodolite Tracking Aircraft

光电经纬仪获取的跟踪测量图像,记录了目标飞机运动过程的各种事件和姿态信息:如空间位置、运动轨迹、运动速度、运动加速度及俯仰、偏航、滚动的3D姿态变化等。但传统光电跟踪图像处理将目标飞机等效为一个质点,因而得不到飞机的3D姿态信息,致使图像中蕴含的目标飞机外形形状及姿态信息都舍弃了。论文开展的光电经纬仪跟踪飞机的3D姿态方法研究,就是设法利用光电经纬仪获得的跟踪数据,去充分挖掘跟踪图像中隐含的信息:既得到飞机的运动信息,又得到飞机的3D姿态信息,并可在事后还原飞机当时的运动情形,以便对飞机的飞行性能进行分析、判断、评估和验证,或者在试验分析、事故鉴定、训练评估、飞控系统检验及新型号的设计定型等方面发挥相应的作用。

The measuring images of aircraft tracked by photoelectric theodolite,record thevarious events and attitudes information of the aircraft during the motion process：such as space position,moving trajectory,moving speed,moving acceleration and-pitch,yaw,roll changes. However,the aircraft is made as a particle in traditional imageprocess of electro-optical tracking,it can not obtain the 3 D attitudes information,so theshape and attitude information of the aircraft is discarded. The study of 3 D methods study for photoelectric theodolite tracking aircraft carried out in this dissertation,is to fully acquire the hidden information exist inthe image by the optical theodolite tracking data,not only the aircraft movement information,but also the aircraft＇s 3 D attitudes.Base on that,the aircraft＇s flight performance can be analyzed,judged,evaluated and validated,or it plays a corresponding role in test analysis,incidentidentification,training evaluation,flight control system testing and new model＇sdesigning.
