摘要In order to improve the ability to find faint small solar system bodies, a method of shifting and stacking images which improves the detection efficiency of faint moving objects is applied to process the sequential optical images. This method determines the existence of moving objects by using False Position Method to estimate the apparent velocities of moving objects, then determines iteratively accurate position of moving objects based on SNR (Signal-to-Noise Ratio) and elongation. Using the sequential images of the China Near Earth Object Survey Telescope (CNEOST), we carry out a trial experiment and succeed in detecting asteroids fainter than 21 magnitude which are invisible on a single image. At last the feasibility of this method is proved.
