The invention discloses a scene-based automatic driving simulation test evaluation service cloud platform and an application method thereof. The system invention is used for automatic driving simulation test and is provided with a client, a cloud and a background management terminal, the client transmits corresponding function operation requirements to the cloud through a function module interface, and the cloud drives corresponding function modules to execute corresponding functions according to the function operation requirements; and the background management terminal manages and maintainsthe cloud and the client. In platform application, the method comprises functional applications of data uploading, data fusion, scene extraction, scene labeling, scene analysis, scene generation, simulation analysis and test evaluation. The whole tool chain including the scene database, the scene extraction and labeling, the scene analysis, the scene generation, the simulation analysis, the test evaluation and the like is integrated to the cloud, unified scheduling, management and use of automatic driving simulation data and test evaluation resources are realized, and the test efficiency is improved.
