A major consideration in designing imaging systems that will be placed on moving platforms is the stability of the image. For example, the tracking or cuing of small objects requires a very steady image sequence. To provide the necessary stabilized platform typically requires the use of an inertial stabilized gimbaling system. Such gimbaling systems are both expensive and bulky. These factors are becoming increasingly important to the military community. The cost of a gimbal system can preclude its use on disposable ordinance systems and can be a significant portion of the cost of such systems. A low cost and low bulk alternative is needed. This paper describes a method for performing electronic stabilization using optical flow techniques. Electronic stabilization allows either the elimination of the inertial stabilized platform or the use of a low cost gimbal. The operating scenario available to electronic stabilization is examined and the resulting basic system requirements are derived. A model- based approach for deciding sensor motion is described. The utilization of the motion information for performing motion compensation is presented. Finally, preliminary results are given.
