Virtual Reality-Based Forward Looking Sonar Simulation

In this paper, virtual reality and its related algorithm was used to simulate the installation on the underwater vehicle forward-looking sonar, designs a single beam based on collision detection technique, the mechanical scanning or multi-beam active detection two ways of new type of collision detection analog sound beam, in real time under the premise of guarantee system, sensing complex virtual terrain and mobile obstacles. Software program method is used instead of rotating mechanism such as physical realization simulation of forward looking sonar detection scans, good simulation results have been achieved. Results show that the simulator can provide according to the requirements for the obstacle avoidance system based on real data to construct the information such as the submarine topography and mobile obstacles, to improve the algorithm of obstacle avoidance problem provides a new way of thinking.
