Abstract :
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
