device and method for geometrically calibrating sensor data generated with the aid of a sensor system of a vehicle

A system for geometrically calibrating sensor data, which are generated with a sensor system of a vehicle and which correspond to the vehicle surroundings, comprising:

• an ascertainer to ascertain a geometric variable in sensor units of a physical object of the vehicle surroundings based on the sensor data;
• a retriever to retrieve the geometric variable in real physical units of the physical object from a database in which geometric variables in real physical units of physical objects, which are assigned to a path, are stored;
• and
• a computer to compute a conversion factor for converting sensor units into real physical units based on the ascertained geometric variable in sensor units and on the retrieved geometric variable in real physical units.
