specific Embodiment
[0054] The purpose of the present invention is to use the reinforcement learning model to realize the optimal autonomous obstacle avoidance scheme under various constraint conditions. The embodiment uses the UWsimulator open source platform based on ros to construct. In the experiment, the simulated AUV is equipped with forward-looking and downward-looking image sonar, regardless of the influence of ocean current and roll.
[0055] 1. Use UWsimulator and blender to build a more complex seabed simulation environment, including various regular and irregular obstacles and terrains. For details, see image 3 ;
[0056] 2. Judging how obstacles should be avoided through the autonomous obstacle avoidance logic rules of submarine navigation. The main methods include adjusting AUV depth and yaw. Adjusting the AUV depth can avoid obstacles without changing the predetermined optimal route. Therefore, it is necessary to judge based on the height of the obstacle detected by the sonar. W...
