The invention is suitable for the technical field of automatic driving, and provides an automatic driving test scene generation method and device, terminal equipment and a medium, and the method comprises the steps: collecting traffic accident data, carrying out the descriptive statistical analysis of the traffic accident data, and determining a typical accident scene; extracting a pre-collision track of an accident participant in the typical accident scene according to the traffic accident data corresponding to the typical accident scene; constructing a collision trajectory generation model for synthesizing pre-collision trajectories, and inputting the pre-collision trajectories into the collision trajectory generation model to obtain a plurality of synthesized pre-collision trajectories; and for each synthetic pre-collision trajectory, constructing derivative traffic accident data corresponding to the synthetic pre-collision trajectory, and according to the derivative traffic accident data, generating an automatic driving test scene. According to the method and the device, generation of low-risk redundant accident scenes can be effectively reduced, so that the accuracy of safety evaluation is improved.
