ABSTRACT:
A gigapixel image is generated from a set of images in raw format depicting different portions of a panoramic scene that has up to a full spherical field of view. Radiometric alignment of the images creates a set of images in radiance format. Geometric alignment of the radiance format images creates a set of true poses for the images in radiance format. A gigapixel image depicting the entire scene is assembled from the set of radiance format images and radiance format true poses for the images. The set of images in raw format is captured using a conventional digital camera, equipped with a telephoto lens, attached to a motorized head. The head is programmed to pan and tilt the camera in prescribed increments to individually capture the images at a plurality of exposures and with a prescribed overlap between images depicting adjacent portions of the scene.
