Conic based image transfer for 2-D objects: a linear algorithm

摘要

This paper presents a study, based on conic correspondences, on the relationship between two uncalibrated images. We show that, for a pair of corresponding conice, the parameters representing the conics satisfy a linear constraint. We also present a linear algorithm for uniquely determining from the coefficients of this constraint the transformation between corresponding points or line in the two images up to a scale factor. Accordingly, conic correspondences enable us to easily handle both points and lines in uncalibrated images of a planar object.
