A stereo mosaic representation has been developed for fusing imaging data captured by sensors (cameras) in motion. In addition to providing a wide field of view, the multiperspective mosaics with various oblique views represent occlusion regions that cannot be achieved by using stationary sensors. One or multiple stereo pairs can be formed from mosaics with different oblique viewing angles and thus can be used for 3D viewing and 3D reconstruction. This approach has been applied to a number of

When something serious happens in a metropolitan area like New York City, imagine a technology that can fly an airplane with a video camera through the area, detect, measure, and analyze the static and dynamic objects in the area, and then reconstruct the scene into multiple three-dimensional (3D)
