Forward bundle adjustment
In a recent post I wrote about the essential matrix. If the internal parameters (pixel pitch, focal length, principal point) of both cameras in a stereo rig are known, the essential matrix can be obtained from at least eight couples … Continue reading
An alternative derivation of the DLT for homographies
What if in the linear system the unknowns are not but the matrix ? Of course, if we have a sufficient number of such systems , , … with the same matrix and independent second hands, we can stack them, and solve … Continue reading
