Abstract
Description
technical field
[0001] The invention belongs to the technical field of aerial image processing, and in particular relates to an aerial image motion compensation circuit at different speeds, a CCD driving circuit and a driving method. Background technique
[0002] In the reconnaissance process, the reconnaissance plane often needs to fly at high speed and low altitude (high speed and height ratio) in order to avoid radar surveillance. At this time, image motion blur will inevitably appear in aerial imaging. The formation of image motion blur is closely related to the flight attitude of the carrier aircraft. Different parameters such as the flight speed, altitude, roll angle, yaw angle, and pitch angle of the carrier aircraft will produce different image motion forms. Among them, when the carrier aircraft is flying sideways or the lens is pitched to the side, the aerial camera on the carrier aircraft will be in a squint working state. At this time, different positions on the ...
