Relative orientation from 5 points: a somewhat more polished C routine implementing the minimal solution for relative orientation of two calibrated cameras from unknown 3D points. 5 points are required and there can be as many as 10 feasible solutions (but 2-5 is more common). Also requires a few CLAPACK routines for linear algebra. There s also a short technical report on this (included with the source). Written by B triggs.
