Abstract
A method of adjusting texture coordinates based on control regions in a panoramic image is disclosed. The method comprises determining warping coefficients of a plurality of control regions in a panoramic image; retrieving two selected warping coefficients out of the warping coefficients for each of a plurality of camera images with respect to each vertex from a first vertex list according to two coefficient indices for each camera image in its data structure; calculating an interpolated warping coefficient for each camera image with respect to each vertex according to the two selected warping coefficients and a coefficient blending weight for each camera image in its data structure; and, calculating modified texture coordinates in each camera image for each vertex according to the interpolated warping coefficient and original texture coordinates for each camera image in its data structure to form a second vertex list.
