Abstract :
This paper proposes a method for calculating exterior orientation parameters (EOPs) of images based on the condition that the straight line in the image space and corresponding line in the object space are coplanar. Experimental results have proved the feasibility and validity of this method, and the accuracy of EOPs is within one pixel and similar to that of point-based method. The position and direction of line segments have influence on the precision of EOPs, and the influences are analyzed academically. The reliability of precision analytical results has proved by utilizing simulated image.
