Transformation to the normal case of general noncalibrated projective stereo pairs
G. Brandstaetter · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1994
Presupposing relative orientation of projective bundles, the transformation to the normal case of `projective stereo pairs' is treated. The image coordinates do not refer to fiducial marks but to the content of the images whose image distances may be unknown. Hence the two images may originate from different nonmetric photographic cameras too. The method presented here uses projective image correlation and can be applied to both, digital and -- using photographic rectification -- analog images. The result is a normal case stereo pair without vertical parallaxes, which contains common parallel and horizontal epipolar lines.
