Abstract
In general, the present disclosure relates to persistent surveillance (PS), wide medium and small in area, and large volume data streaming (LVSD), e.g., from orbiting aircraft or spacecraft, and PS/LVSD specific data compression. In certain aspects, the PS specific data or LVSD compression and image alignment may utilize registration of images via accurate knowledge of camera position, pointing, calibration, and a 3D model of the surveillance area. Photogrammetric systems and methods to compress PS specific data or LVSD while minimizing loss are provided. In certain embodiments, to achieve data compression while minimizing loss, a depth model is generated, and imagery is registered to the depth model.
