Abstract
Automatic scene scanning and digital video processing are combined in a sensor/assessment system called VISDTA. In fixed-site or mobile security applications, the operator can initiate automatic scene scanning. While scanning, detection algorithms process video from a thermal imager or low-light camera. An additional detection algorithm operates on single fixed scenes. Video is displayed with graphics on a monitor next to the operator's touch-panel display. Assessment by the operator is aided by zoom/focus control, pan/tilt control, and range measurements. Detection ranges can be kilometers. In this paper, the system design is described, along with highlights of the user interface, and performance estimates are made.
