For surveillance and reconnaissance tasks small UAVs are of growing importance. These UAVs have an endurance of several hours, but a small payload of about some kilograms. As a consequence lightweight sensors and cameras have to be used without having a mechanical stabilized high precision sensor-platform, which would exceed the payload and cost limitations. An example of such a system is the German UAV Luna with optical and IR sensors on board. For such platforms we developed image exploitation algorithms. The algorithms comprise mosaiking, stabilization, image enhancement, video based moving target indication, and stereo-image generation. Other products are large geo-coded image mosaics, stereo mosaics, and 3-D-model generation. For test and assessment of these algorithms the experimental system ABUL has been developed, in which the algorithms are integrated. The ABUL system is used for tests and assessment by military PIs

UAV have a growing importance for reconnaissance and surveillance. Due to improved technical capability also small UAVs have an endurance of about 6 hours, but less sophisticated sensors due to strong weight limitations. This puts a high strain and workload on the small teams usually deployed with such systems. To lessen the strain for photo interpreters and to improve the capability of such systems we have developed and integrated automatic image exploitation algorithms. An import aspect is the detection of moving objects to give the photo interpreter (PI) hints were such objects are. Mosaiking of imagery helps to gain better oversight over the scene. By computing stereo-mosaics from mono-ocular video-data also 3-d-models can be derived from tactical UAV-data in a further processing step. A special instrument of gaining oversight is to use multi-temporal and multifocal images of video-sensors with different resolution of the platform and to fusion them into one image. This results in a good situation awareness of the scene with a light-weight sensor-platform and a standard video link
