Patent Images
1. A method for detecting and tracking a target comprising:
- capturing an image of a field of view from at least two cameras mounted on one or more platforms;
identifying landmarks within the images;
merging the images to detect the target;
comparing information about the target from at least one sensor; and
displaying the target location with respect to the position of the platform.

Abstract
Methods and apparatus are provided for detecting and tracking a target. Images are captured from a field of view by at least two cameras mounted on one or more platforms. These images are analyzed to identify landmarks with the images which can be used to track the targets position from frame to frame. The images are fused (merged) with information about the target or platform position from at least one sensor to detect and track the target. The targets position with respect to the position of the platform is displayed or the position of the platform relative to the target is displayed.

25. A method for detecting and tracking a target comprising:
-
capturing an image of a field of view from three cameras mounted on a platform; identifying landmarks within the images utilizing a scale invariant feature process; merging the images to detect the target using a Kalman filter video triangulation process; comparing information about the target from at least one inertial sensor; and displaying the platform location with respect to the position of the target or the target location with respect to the position of the platform.
