Rectified Mosaicing: Mosaics without the Curl
Whenimages captured by a tilted camera are mosaiced into a panorama, the resulting mosaic is curled. This happens,for example, with a panning camera that is not perfectly horizontal, and with a translating camerafacing a tilted planar surface. The tilt of the camera causesdifferencesin image velocity betweenthe top and bottomparts of the image, causing the curled mosaic. In rectified mosaicing thesedistortions are overcomeby warping the strips into rectangles, while keeping some imagefeature invariant. This warping equalizesthe imagemotion at thedifferent imageparts, and the resulting mosaic is straight. Mosaicing is done without camera calibration or knowledgeof the scene, and theprocess adapts automatically to smooth changesin the sceneand the imaging conditions.
