1. A computer-implemented process for generating a gigapixel image, comprising using a computing device to perform the following process actions: inputting a set of images, wherein the set of images comprises a plurality of captured images in raw pixel data format, each of which depicts a portion of an overall panoramic scene with an amount of overlap between images that depict adjacent portions of the scene; performing radiometric alignment of each captured image, resulting in the creation of a set of captured images in radiance pixel data format; performing geometric alignment of each captured image in its radiance pixel data format, resulting in the creation of a set of true poses for the captured images in radiance pixel data format; and assembling a seamless gigapixel image from the set of captured images in radiance pixel data format and the set of true poses for the captured images in radiance pixel data format.
