U.S. Pentagon scientists have developed the Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System (ARGUS-IS), a sensor system that can spot and track more than 65 targets simultaneously from altitudes higher than 20,000 feet. ARGUS-IS "could provide video situational awareness for an area more than 40 square kilometers, an area the size of a small city," says Defense Advanced Research Projects Agency's Richard Spearman.
The system consists of 368 five-megapixel video chips in four cameras. The images from each camera are merged to create one large, high-definition image.
ARGUS-IS transmits a full-resolution image of everything it sees to a ground station where operators can draw a box around an area of interest, which is then transmitted through a high-resolution video. The system's processor, which can handle 400 gigabits of data every second, incorporates 28 parallel processors. Computer algorithms recognize shapes, color, motion, and can follow a moving object. If the tracked object goes out of view, the software predicts where it is expected to emerge.
