摘要
航空相机搭载在高速飞行的飞机平台上工作,在成千上万米高空对地进行侦照,高度的变化以及恶劣的使用环境,都对相机的成像造成不利的影响.随着航空侦察装备的跨越式发展,必须加装调焦系统,才能满足其成像质量要求.论文在仿真分析不同因素对离焦影响规律的基础上,对比研究了程序补偿法和光电自准直法两种典型补偿方法的原理及特点,并对两类新型图像法调焦进行了讨论,最后给出了检焦系统精度测定评估的方法,展望了航空相机离焦补偿技术及发展趋势.
Abstract
The aerial camera is mounted on the aircraft platform flying at high speed,and the detection is carried out at thou-sands of meters high.The change of altitude and the harsh operation environment have an adverse effect on the imaging of the cam-era.With the rapid development of aerial reconnaissance equipment,it is necessary to install an focusing system to meet its imaging quality requirements.On the basis of simulation analysis of the influence of different factors on the dispersion,this paper compares the principle and characteristics of two typical compensation methods,program compensation method and photoelectric autocollima-tion method,and discusses the two types of new image focusing methods.Finally,the method of measuring and evaluating the accu-racy of the focusing reduction system is given,and the development trend of the defocusing compensation technology for aerial cam-eras if prospected.
