DETERMINATION OF THE THREE-DIMENSIONAL LOCATION OF A TARGET VIEWED BY A CAMERA

A method for determining, in three dimensions, the location of a moving ground object observed in a region by a video camera. A terrain map supplies altitude for the latitude and longitude of each terrain point. The terrain information is combined with camera location, field of view, and orientation to produce a computed terrain map relative to the camera. A video analytics step processes the video and locates moving target(s) in two Cartesian coordinates. The coordinates are processed with the camera information to produce target location in terms of azimuth and elevation angle. The computed map information is combined with the angular target location to produce latitude, longitude, and altitude of the target. The target location information is used for further investigation or to attack the target. Also, a method for determining the third dimension of a 2-D radar track to cue a camera or fuse with camera data.
