利用图象序列来检测、识别和选择运动飞机目标,对于诸如航空管制和防空系统有着十分重要的意义.通过运动目标的序列图象来研究运动目标的运动特征,首先要利用序列图象估计目标运动参数和确定目标结构,并建立观测模型,进而才可通过动态三维显示技术迅速地将飞机的飞行动态特征在计算机屏幕上显示出来.由此可见,要进行运动目标研究,就必须获得运动目标的序列图象,而基于特征点重建的三维观测误差正态概率模型的三维飞机运动目标图象序列生成及最优运动估计是通过OpenGL三维图形动态库来实现的.由这种方式产生的运动目标序列图

Detection, identification, and selection of moving target through image sequence are very important to Air Traffic Control System and Air Defense System. To study image sequence of moving target, parameters of nmoving target should first be estimated, and its structure be identified, furthermore an observable model should be built to enable speedily display the performance of visible light radiation of flying target on computer screen adopting three-Dimensional display technology. Based on normal probability model under three-Dimensional observing with error, the generation and optimal estimation of motion parameters of moving target image sequence are realized by using OpenGL three-Dimensional graphics library. Hence the generated image sequence possesses the features of smooth, life-like and high speed. The result of dynamic display of moving target through simulating radar data is satisfactory. If the moving target image are synchronized with practical environment picture, this method will meet the requirement for flight performance test and simulation operation and has greatly valuable in this area.
