The embodiment of the invention provides a test scene generation and screening method, and relates to the technical field of intelligent driving test. The method comprises the steps of generating a test scene set according to a design operation boundary of an intelligent driving algorithm and influence factors of operation of the intelligent driving algorithm; under the condition that real vehicle test conditions or virtual driving platform test conditions exist, training a logistic regression classifier by using part of the test scene sets, determining risk levels of all scenes in the test scene sets by using the logistic regression classifier, and dividing the risk levels according to risk degrees perceived by a user for the test scene sets; and under the condition that a real vehicle test condition and a virtual driving platform test condition do not exist, constructing a user risk expectation model according to the design operation boundary and the dynamic risk source in the influence factors, and determining the risk level of each scene in the test scene set by using the user risk expectation model. The risk level of the test scene is determined based on the psychological risk expectation of the user, and the test efficiency of the intelligent driving algorithm is improved.
