N2 - The computation of image motion velocity is the premise of high resolution optical imaging. To solve this problem, the model of image motion velocity for spaceborne cameras is established in this paper. The positions of a target and the pixel plane are expressed in the camera coordinate system based on five coordinate systems and multiply coordinate translations. The calculation formulas of target position and image motion velocity are deduced. The method, in which the orbit and attitude parameters are considered as a whole, is applicable for complex imaging missions and general orbits. The practical value of the study lies in image motion velocity compensation, drift angle compensation, and the location of observed target. Finally, the mathematical simulation shows that the model and the derivation are correct under several typical applications.
