Method for Detecting at Least One Object Present on a Motor Vehicle, Control Device, and Motor Vehicle

The invention relates to a method for detecting at least one object present on a motor vehicle, wherein by way of a control device, at least one camera image is captured by means of a camera, wherein a detection region of the camera is directed to an outer region of the motor vehicle, and partially or entirely to an outer surface of the motor vehicle. The invention proposes that for a clearance test in the at least one camera image, it is checked by an image analysis device of the control device, if at least one predetermined intrinsic structure of the motor vehicle is imaged, and in the event that at least one intrinsic structure cannot be found by the image analysis device, a blocking signal, which indicates that an object is present on the motor vehicle is generated.
