Vision can provide unique capabilities under favorable visibility conditions during the operation of intelligent or autonomous underwater vehicles in deep ocean. We describe a real-time vision system for positioning and station keeping, navigation, and sea floor image mosaicing. These developments exploit a direct methodology for 3D motion estimation from time-varying underwater imagery. We present sample results from experiments for evaluating the performance and accuracy of the system, based on measurements from an independent sensor.
