Research on Dedocus Compensation and Its Accuracy Measurement Technology for Aerial Camera
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.
