| Abstract(in English) | A procedure is described for determining structure from motion in the uncalibrated case. It is shown that a camera with unknown focal length undergoing arbitrary motion can be self-calibrated via closed-form expressions in the elements of two special matrices. Techniques are given for robust determination of these matrices up to a scale factor via least-squares methods, and for the elimination of outlying flow vectors. Experimental results the approach holds promise. |
