Abstract
In one embodiment, an augmented view is provided utilizing a panorama. A panorama of the physical environment is captured with a panoramic camera. The panorama has a panoramic field of view and is embodied as a sequence of video frames. An initial pose of the panoramic camera is determined. The panoramic camera is tracked to update the initial pose to subsequent poses to account for movement of the panoramic camera about the physical environment. The tracking utilizes features dispersed across the panoramic field of view of video frames. The panorama is augmented by merging computer-generated elements with the panorama based on the updated pose of the panoramic camera. A sub-portion of the panorama, along with the computer-generated elements, is displayed as an augmented view. The displayed augmented view may have a field of view that is less than the panoramic field of view.
