With the continuous development and progress of science and technology, the use of virtual environment technology to simulate obstacle avoidance of autonomous underwater vehicles has gradually become a mainstream trend. For this reason, a new type of system has been developed, that is, a visual simulation system for obstacle avoidance of autonomous underwater vehicles. This article analyzed the overall structure of the visual simulation system for AUV obstacle avoidance and the simulation method in the virtual environment, utilized Multigen Creator to conduct AUV modeling, and then used Vega software to establish a three-dimensional ocean scene and set the corresponding target points and object obstacles. Through simulation, it was found that the currently established virtual obstacle avoidance system was very similar to the real environment, and could accurately simulate the underwater obstacle avoidance movement of the vehicle. In the whole process, it could give full play to the function of obstacle avoidance algorithm to the greatest extent, and really provide a certain reference for the obstacle avoidance of related vehicles.
