A geometric constraint method for estimating 3-D camera motion
We investigate the problem of estimating the camera motion parameters from a 2D image sequence that has been obtained under combined 3D camera translation and rotation. Geometrical constraints in 2D are used to iteratively narrow down regions of possible values in the space of 3D motion parameters. The approach is based on a new concept called "FOE-feasibility" of an image region, for which an efficient algorithm has been implemented. Results are shown on real images.<<ETX>>
