Generation of Spatial-Temporal Panoramas with a Single Moving Camera

Development of image stitching techniques, which take multiple images and stitch them together to make natural looking panoramas, is an integral part of the new wave in visual media - the 360 surround displays, such as the Oculus Rift. However, as compared to static image stitching, there has been little research conducted on video stitching, especially methods of generating panoramic video content from a single moving video camera. In this paper we present an effective means of creating video panorama from a single camera. Our video stitching method allows for widening the field of view of a video while maintaining spatial-temporal consistency. In this approach, a single image warping transformation, or homography, is obtained by averaging several rotation matrices from several frames. The application of the same homography to every frame, with fixed camera intrinsic parameters, provides enhanced stability of the resulting panoramic video. This novel stitching method can be used for a variety of applications, such as allowing the creation of panoramic video with smartphones and enabling gaming and movie companies to make panoramic video content in a flexible and inexpensive manner.
