Data processing method and device, equipment and medium

The invention provides a data processing method and device, equipment and a medium, and relates to the technical field of automatic driving vehicles, and the method comprises the steps: obtaining an accident environment where an accident vehicle is located and driving behavior data of a driver in a preset time period before an accident, and obtaining a simulation result according to the accident environment, the driving behavior data and a preset simulation environment; and constructing an accident simulation scene of the accident vehicle, and sending the accident simulation scene to the verification device to determine whether the driving behavior of the driver before the accident occurs is normal. In the technical scheme, the accident simulation scene which does not contain the driver information can be obtained through simulation based on the driving behavior data of the driver and the accident environment before the accident occurs by using the preset simulation environment, and the personal information o
