In this paper, we present the Video Flashlight System and 3D Visualization Display for providing total battlefield situation awareness by integrating a blanket of ground and aerial video cameras, and UGS data within a 3D model of the site. The system enables visualization of an integrated view of a scene, combining video and sensor data from multiple cameras and UGS. Users can move seamlessly in space -- monitor a site from an aerial view and fly-down to examine suspicious activity up close. The system detects moving objects from all cameras and provides an integrated view of all motion in the monitored zones. Users can click on a moving object to get a zoomed-in view or updated data from the sensor. The aerial and ground videos are geo-registered to a world coordinate system. GPS-located UGS data is correctly positioned on the 3D display. Finally, the system can be used to track multiple objects from camera to camera and make measurements such as velocity, etc., and to fuse data from other emplaced sensors into the displayed scene.
