Paper Abstract

The reference data consists of two or more central- projection images of a 3D distribution of object points, i.e., a 3D scene. The positions and orientations of the cameras which generated the reference images are unknown, as are the coordinates of all the object points. We derive and demonstrate invariant methods for synthesizing nadir and perspective views of the object points, e.g., 2D maps of the 3D scene. The techniques we will demonstrate depart from standard methods of resection and intersection which first recover the camera geometry, then reconstruct object points from the reference images, and finally back-project to create the nadir or perspective views. The first steps in our 'invariant methods' approach are to perform the image measurements and computations required to estimate the image invariant relationships linking the reference images to one another and to the new nadir and perspective views. The empirically estimated invariant relationships can thereafter be use to transfer conjugate points and lines from the reference images to their synthesized conjugates in the nadir and perspective views. Computation of the object model...the digital elevation model...is not required in this approach. In this paper we developed algorithms for invariant transfer of conjugate lines which exploit the synergy of line and point transfer. We validate our algorithms with synthetic CAD models. A subsequent paper will validate the line transfer algorithms with uncontrolled aerial imagery and maps with occasional missing or inaccurately delineated features.
