Paper 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 .
