N2 - In order to improve the efficiency of remote sensing imaging, aerial cameras use vertical swing sweep motion to take imaging. Because the optical axis of the camera rotates at a certain speed in the swing sweep direction, there is a gap between the image formed by the imaging target on the focal plane and the photosensitive medium. Relative motion brings about image motion blur, which will seriously affect the image quality of the camera. Eliminating the problem of image quality degradation caused by this scanning image shift is a problem that must be solved for wide-scan imaging. In the thesis, the mechanism of side-sweeping and the effect of image shifting on the image are analyzed, and the necessity of image-shift compensation is explained. The design adopts an optical mirror-based swing-sweeping image shift. The compensation device performs scanning image motion compensation, and calculates the principle and accuracy of image motion compensation. Through ground image motion compensation test and flight test test, the image motion compensation imaging effect is good, which can meet the requirements of pendulum sweep aerial imaging image motion compensation.
