Application of Virtual Reality to Bottom Tracking of Autonomous Underwater Vehicle

Based on software platform Vega and MultiGen Creator, a simulation system of autonomous underwater vehicle(AUV) for bottom tracking has been developed. The selection of software, the model construction, the generation of virtual ocean environment and terrain, the implementation of fuzzy rules, and the application of virtual reality techniques are all introduced in detail. Simulation results show that this simulation system can precisely simulate the interaction in the environment, and realistically display the dynamic bottom tracking process of AUV. The simulation system may be applied to the simulation of obstacle avoidance control and cooperating control of AUV in the future.
