SYSTEM AND METHOD FOR HEAD SIZE EQUALIZATION IN 360 DEGREE PANORAMIC IMAGES

摘要

A real-time approximately 360 degree image correction system and a method fo r alleviating distortion and perception problems in images captured by omni- directional cameras. In general, the real-time panoramic image correction method generates a warp table from pixel coordinates of a panoramic image an d applies the warp table to the panoramic image to create a corrected panorami c image. The corrections are performed using a parametric class of warping functions that include Spatially Varying Uniform (SVU) scaling functions. Th e SVU scaling functions and scaling factors are used to perform vertical scali ng and horizontal scaling on the panoramic image pixel coordinates. A horizonta l distortion correction is performed using the SVU scaling functions at at lea st two different scaling factors. This processing generates a warp table that c an be applied to the panoramic image to yield the corrected panoramic image. In one embodiment the warp table is concatenated with a stitching table used to create the panoramic image.
