3D reconstruction from 360/spl times/360 mosaics

We are studying the geometry of a 360/spl times/360 mosaic image formation. A 360/spl times/360 mosaic camera model and a calibration procedure are proposed. It is shown that only one point correspondence is needed in order to acquire epipolar rectified images. The 360/spl times/360 mosaic camera model is therefore determined by only one intrinsic parameter It is shown that the relation between coordinates estimated with different values of intrinsic 360/spl times/360 mosaic camera parameters is a scaling of all scene point coordinates with additional nonlinear changes in the z coordinates of the scene points. Experimental results verifying the reconstruction of real scene points are presented.
