Reconstruction of Fiducial Marks and Cameras Utilizing Simultaneously All the Photographs Available

摘要

We describe in this paper a program to calculate a posteriori the coordinates of a set of points photographed by n cameras, together with the positions and orientations of the cameras, also not known a priori. The coordinates of the cameras are obtained by an unique fit, requiring the points measured on the pictures to be images of true points, existing somewhere in space. The coordinates of the points photographed are then easily obtained.
