Based on the type of the aerial camera and the principles and the features of its follow-up system

this paper analyses geometric distortion type and its features. Geometric rectification model of the system and its coefficient matrix are built. But the way of getting coefficient matrix for geometric rectification model is simplified ulterior by analyzing the principles of its follow-up system because of the requirement of the real time system. At the same time

other factors are considered based on the application environment of the system. The algorithm in the paper resolves auto geometric rectification of area CCD camera with fellow-up system. The output of the flight test proves the usefulness and availability of the algorithm.
