Method for constructing virtual scene library of automatic driving automobile

The invention relates to a method for constructing a virtual scene library of an automatic driving automobile. The method comprises the steps of data acquisition, data extraction, data cleaning, sceneelement labeling, data set formation, optimal k value determination, clustering initial center determination, logic scene acquisition, virtual scene library construction and the like. According to the invention, theoretical basis and technical support are provided for the construction of the automatic driving virtual scene library; the method is simple and convenient to operate, a large number oftest target scene environments with different requirements can be provided; the method is used for testing the safety of the automatic driving system in a virtual scene, replaces the testing of a real vehicle in an actual environment, saves a large amount of cost, is higher in testing efficiency, is higher in repeatability, can simulate various scenes with different requirements, and can accelerate the research and develo
