Abstract

Abstract

The traditional monocular vision system has certain limitations when space azimuth is measured. It is not feasible for the condition under which the object is without the scope of the CCD field. Therefore, a kind of rotation matrix method to measure the objects space azimuth under CCD non-vision area is proposed. According to the principle of Zhang Zhengyou calibration method, the rotation matrix method, through processing with feature points on the cooperative target, works out rotation axiss space azimuth of the cooperative target. Then the objects space azimuth under CCD non-visual area is indirectly obtained. Experiments indicate that the rotation matrix method has certain feasibility and stability, and the root mean square error of the objects space azimuth calculated by this method is lower than 0.06.
