1. A distance determination method by means of a camera sensor, comprising the steps of: capturing a piece of camera information as a basis for determining a distance from the camera sensor to a target object, in that the camera information is related to a physical extent of a region covered by the target object on a photo sensor in the camera sensor; in that the camera information related to a physical extent of a region covered by the target object on a photo sensor in the camera sensor is logically combined with a further piece of information about the physical extent of the target object; in that the further piece of information related to the physical extent of the target object is in the form of at least one of the physical extent along the horizontal axis, the physical extent along the vertical axis, and the cross-sectional area of the target object; and in that the further piece of information about the target object comprises the direction of movement of the target object relative to the camera sensor.
