Abstract
Methods, systems, and articles of manufacture for generating a panoramic image of a long scene, are disclosed. These include, fitting a plurality of planes to 3D points associated with input images of portions of the long scene, where one or more respective planes are fitted to each of a ground surface, a dominant surface, and at least one of one or more foreground objects and one or more background objects in the long scene, and where distances from the 3D points to the fitted planes are substantially minimized. These also include, selecting, for respective one or more pixels in the panoramic image of the long scene, one of the input images and one of the fitted planes such that a distance is substantially minimized from the selected one of the fitted planes to a surface corresponding to the respective one or more pixels and occlusion of the respective one or more pixels is reduced in the selected one of the input images; and stitching the panoramic image of the long scene by projecting, for the respective one or more pixels in the panoramic image of the long scene, the selected one of the input images using the selected one of the fitted planes into the virtual camera.
