A method for creating a 360 degree panoramic image from multiple images includes (1) computing a gross rotation error DeltaR between a first image and a calculated first image rotated to be stitched to a last image, and (2) spreading the gross rotation error DeltaR to each pixel on the panoramic image. Spreading the gross rotation error DeltaR includes (1) computing a rotation angle theta0 and rotational axis n0 from the gross rotational error DeltaR, (2) determining an angle alpha of each pixel, and (3) determining a compensation matrix Rc for each pixel using the following formula: R,(a)=R(2pi/alphatheta0). Spreading the gross rotation error DeltaR further includes (4) tracing a pixel on the panoramic image to a camera optical center of the images to form a first ray, (5) determining a second ray originating from the camera optical center that would be rotated by the compensation matrix Rc to coincide with the first ray, (6) tracing the second ray to a second pixel on one of the images, and (7) painting the first pixel with color values of the second pixel.
