Paper Abstract

Video sensors represent one facet of the unattended ground sensors family used to support military operations. This paper provides technical details on a modular, automated video surveillance (AVS) system concept that provides a 4D modeling and segmentation capability. This capability, combining 3D imaging and embedded information processing, enables the AVS to reliably detect and roughly classify objects and activities with a high probable certainty and minimal false alarms. The beneficial result is an elimination of the need for human monitoring and reduction in data transmission requirements by several orders of magnitude. This modular, forward observer AVS sensor package is comprised of integrated CMOS arrays and lenses (one for monoscopic view and two rigidly fixed for stereo), image processing, communication, GPS chips, and battery. This smart sensor is inexpensive, miniature, self-contained, and man-packable. Real-time video processing onboard the sensor provides: analysis and automatic target recognition algorithms enabling robust moving object detection; tracking and delimitation; and target characterization based on motion, size, form factor, texture, and specific identifying characteristics of objects. Automation of video screening tasks provides the benefits of visual surveillance without the associated burden or distraction from the mission. Because of its size and simplicity the AVS requires minimal man-in-the-field set up and lends itself to clandestine deployment.. In the future it may be possible to reliably and cost effectively air deploy the AVS. Each method offers great benefits as unmanned forward observers and sophisticated `tripwires' for battlefield awareness. While well suited for military reconnaissance, surveillance, and target acquisition missions for peacetime and/or wartime applications, the AVS also lends itself to other clandestine applications such as drug interdiction surveillance, monitoring, and tip off.
