%X A new algorithm to measure the drift of rockets in the initial launching stage is presented and developed.It is designed to combine the improved SUSAN detector and the correlation.In this method,the corner detector is improved to detect the edge.Meanwhile,the direction of Gradient is recorded.After filter,the coordinates of corners are calculated accurately by using the edge pixels with special direction.The precision and the anti-noise performance is improved by this method.The results show that the precision reaches sub-pixel,with few mistake in detecting,and this algorithm is easy to realize for its less operations.
