Abstract: The present disclosure discloses a method for determining the absolute position of a mobile unit, which has at least one optical surroundings sensor that captures a detection area of the environs of the mobile unit, in a predefined navigation environment, wherein optical, distinguishable markers which can be detected by the surroundings sensor are used in the navigation environment, wherein, for position determination, at least one marker is detected and identified, by means of an image processing algorithm, in sensor data recorded by at least one of the at least one surroundings sensors, and a relative position between the mobile unit and the marker is determined taking account of the position of the marker in the sensor data, and an absolute position of the mobile unit is determined as a function of the relative position and the absolute position of the marker.

Abstract: The invention relates to a method for assigning an identity certificate (I1, I2) transmitted by a vehicle (16, 18) to an object (O1, O2, O3, O4), which is detected by a sensor device (28) in identification apparatus (22) external to the vehicle. To this end, the identification apparatus receives the identity certificate (I1, I2), measures by means of the sensor device (28) a first value (V1) relating to at least one operating parameter of the object, receives a second value (V1, V2) of the vehicle (16, 18) relating to the at least one operating parameter and determined by the vehicle (16, 18) itself, compares the first value and the second value of each operating parameter with each other and assigns the identity certificate (I1) to the object (O1) if the two values for each operating parameter match.
