<p>A dual field of view (FOV) image is generated as a combination of a small footprint image and large footprint image, where the large footprint image is generated based on rendering to the current viewpoint at least a first image captured relatively farther away from a target so as to appear as a continuation of a small footprint image which is relatively closer to the target. Preferably, both the first image and the small footprint image are captured with the same fixed narrow field of view (NFOV) imaging device. The system is able to operate in real time, using a variety of image capture devices, and provides the benefits of both NFOV and wide FOV (WFOV) without limitations of conventional techniques, including operation at a longer range from a target, with higher resolution, while innovative processing of the captured images provides orientation information via a dual FOV image.</p> |
