Study on the Position Method of Plane Carried Camera by Rotating of Unit Vector

In this paper, a measure for the improvement of the precision of the 3 attitude parameters and an approach estimating prevision are presented under the circumstance that 4 GPS receivers are used for photogrammetry and suppose the opposite position and direction of plane and camera are fixed, by the new approach directly calculating the exterior orientation element by coordinate transformation and rotating of spatial unit vector. And several problems are discussed in the end.
