Abstract

An active focal plane motion compensation system is presented in this paper. In this system, a high speed matrix CCD sensor is used for image motion detection. The matrix CCD sensor is a auxiliary sensor (about 256X256 pixel) which is installed side by side with the main image sensor of the camera. The main image sensor is putted on a micro-displacement platform which is drived by tow piezoelectric actuators. So the main image sensor can shift in tow directions. In order to realize real-time image motion estimation,the Gray Projection algorithm is used to calculate image motion vector. To achieve the required accuracy, the operation of the piezoelectric actuator is controlled in a closed loop system. The results of simulation experiments showed that the accuracy of the motion detection can reach 0.5 ~1 pixel size, and the compensation can be controlled on the scale of sub pixel. theory analyzing demonstrate that proposed method is reasonable and efficient. It will be helpful for space cameras to acquire high resolution images on unstable space platforms .
