Edge test scenario construction for virtual simulation testing
Combined with the key points of intelligent ship testing and verification,analyze the components of high-risk edge test scenarios,realize cross-domain fusion of edge scenario elements in the virtual simulation test system,simulate the game and confrontation behavior characteristics between the ship and other ships and the environment in the real world,and express the scene for the scene.The three sampling levels are proposed,and a virtual test-oriented edge scene construc-tion system is proposed.The scene keywords are extracted based on the semantic model,mapped to the parameter space to generate dynamically changing logical scenes,the scene model is described as a scene dynamics model,the scene controller is constructed by using a general function approximator,and realize the optimal solution of edge scene controller with the help of reinforcement learning.Finally,the parameter space is sampled by keywords to generate specific edge scene files.Taking the simultigle-vessel encounter scene of a test site as an example,the simulation verification is carried out on the vir-tual simulation test platform.The results show that the generated edge scene file can meet the requirements of the automatic driving test of the ship,significantly improve the generation efficiency.And it has good performance in scene interactive game,coverage and repeatable testing,etc.
