Abstract
This paper concerns an efficient algorithm for the solution of the exterior orientation problem. Orthogonal decompositions are used to first isolate the unknown depths of feature points in the camera reference frame, allowing the problem to be reduced to an absolute orientation with scale problem, which is solved using the singular value decomposition (SVD). The key feature of this approach is the low computational cost compared to existing approaches
