It should be noted that, in a specific implementation, the visual recognition device 30 may be set at any appropriate position, and may be specifically set by a user according to actual needs, which is not specifically limited in this embodiment of the application. For example, the visual recognition device 30 may be provided in a cab of the vehicle.
