24 September 1993 Extension of three-dimensional invariant methods to noncentral-projection imaging systems

Invariant relationships have been derived from the mathematical models of image formation for several types of sensors; from the collinearity equations of pinhole camera systems and separately, from the condition equations of strip-mapped SAR. In the present paper, we extend these results by combining the collinearity and condition equations of photographic and SAR systems. The resulting invariants enable us to transfer points and three-dimensional models from multiple photographic to SAR images and vice-versa. Geometric integrity of the different imaging systems is preserved by the technique. The method will facilitate synergistic, model- based interpretation of different sensor types.
