The embodiment of the invention provides a different-speed image motion compensation device and system. The device comprises a main time sequence unit, a different-speed image motion compensation unit, a horizontal time sequence unit and a vertical time sequence unit connected with area array CCD. Pixel columns of the area array CCD are divided into more than one column group. The main time sequence unit generates time sequence signals, the different-speed image motion compensation unit adjusts vertical time sequence signals in the time sequence signals according to task parameters sent by thesystem controller so as to synchronize the vertical moving speed and the image motion speed of charges in each column group, and the adjusted time sequence driving signals are transmitted to the horizontal time sequence unit and the vertical time sequence unit. The horizontal time sequence unit and the vertical time sequence unit amplify and translate the received horizontal time sequence signaland the received vertical time sequence signal respectively, and input the amplified and translated time sequence signals into the area array CCD to drive the area array CCD. Thus, the problem of motion blur of the investigation camera image using the CCD can be solved, and the method and the device have the advantages of being easy to implement and low in cost.
Description
technical field [0001] The present application belongs to the field of aerospace technology, and in particular relates to an image motion compensation device and system at different speeds. Background technique [0002] In the reconnaissance process, reconnaissance aircraft often need to fly at high speed and low altitude (high-speed height ratio, where the speed-to-height ratio refers to the ratio of speed to height) to avoid radar surveillance. When the carrier aircraft is flying sideways or the lens is tilted to the side for imaging, the aerial camera on the carrier aircraft will be in a squint working state. At this time, different positions on the imaging target surface will have different speeds of image motion, resulting in complex motion blurred images. This phenomenon is also called "different speed image motion". The formation of differential image motion is closely related to the flight attitude of the carrier aircraft. Different parameters such as the flight spe...
