Research on image stabilization technology of area-array aerial camera

Aerial camera is an important device on obtaining information by the method of air-to-ground investigation and measurement. The way of forward flight together with pendulum scanning in the direction of wingspan is commonly used for broadening the field of view of aerial camera. The problem of image motion compensation was focused on, which was produced by broadening the field of view. The image motion compensation formulas of the flight and wingspan direction were further derived, and the high practicability compensation scheme was proposed. Based on the MATLAB/Simulink environment,the mathematical model of image motion compensation was simulated and verified. Simulation results show that the compensation scheme is achievable. In the hardware experiment, the circuit which was mainly made of the FPGA chip was used to achieve the function of image motion compensation. The experimental and simulation result curves are in good agreement. The effect images further certificate that the image motion compensation is an indispensable link in improving the imaging quality and resolution.
