And a screwy algorithm based on digital image from mono-view is presented. This algorithm needs the four-region sign with the screwy boundary labeled on the surface of columniform targets. Then the length of the intersecting lines of the object's axis and the screwy boundary are gained by means of digital image processing, such as gray histogram balancing, Susan edge detection and Hough transform. Finally, the object's rolling angle is accurately gotten in shooting range.
