| Abstract: | A new method for measurement of the pitching angle and yaw angle of an axes symmetric object through the optical images is presented, and the accuracy of the method is analyzed. This method is highly accurate because a large amount of information of the object image is used. The difficulty of object matching among several images is avoided since the object's axis is measured in an indirect way. |
