Abstract
We present new algorithms for the recovery of the Euclidean structure
from a projective calibration of a set of cameras of known pixel shape but otherwise
arbitrarily varying intrinsic and extrinsic parameters. The algorithms have a geometrical
motivation based on the properties of the set of lines intersecting the absolute conic.
The theoretical part of the paper contributes with theoretical results that establish the
relationship between the geometrical object corresponding to this set of lines and other
equivalent objects as the absolute quadric. Finally, the satisfactory performance of the
techniques is demonstrated with synthetic and real data.
