ABSTRACT

Sarnoff's role in DARPA's Demo II program is to develop a next generation electronic stabilization system capable of supporting RSTA functions from a moving vehicle. This system must handle much larger camera motion than is possible with current technology, and must stabilize scenes containing significant motion parallax.

Sarnoff's approach is to measure frame to frame image motion by registering each new frame to an extended mosaic constructed from previous frames. The mosaic approach can accommodate larger motion than current techniques that register the new frame to the previous frame. The mosaic can also support moving target detection and the recovery of 3D scene structure.

A baseline electronic stabilization system was installed on the SSV for Demo B. This will be upgraded for Demos C and II.
