Geometric algebra: a framework for computing point and line correspondences and projective structure using n uncalibrated cameras
Eduardo Jose Bayro-Corrochano, Joan Lasenby, Gerald Sommer · 1996
We present geometric algebra as system for analysing the geometry of multiple-view images. The power of this approach is illustrated by giving purely geometric derivations of the constraints, for point and line correspondences in n-views and via a discussion of projective structure.
