Abstract

The mechanism of image motion of Airborne Digital Camera was analyzed and a method of external swing forward motion compensation was proposed in this paper. The forward motion compensation for external swing was achieved through the design of a compensation device to control the rotation of the camera system. In order to simulate the actual motion effect at the most under the laboratory condition, the Stepper Motor Controller (SC) stepper motor controller was designed as the simulation installment to control the guide rail movement. Using this device, compensation speeds and compensation could be controlled, and hence the evaluation of compensation effect could be conducted by image sharpness. The experimental results of the forward motion compensation, show that the compensated remain image motion was less than 2μm (1/3 pixel), illustrating the feasibility and effectiveness of the method proposed in this paper.
