Abstract
The invention relates to a method for calibrating a camera system (7) of a motor vehicle (1). At least one camera (8-11) respectively sequentially generates camera images (21-28) from an environment (2) of the motor vehicle (1). A computing device (12) generates a virtual view (14) of the environment (2) from a virtual perspective from the camera images (21-28) by means of a projection (P). In traveling, the computing device (12) passes at least once a calibration cycle for each camera (8-11). Based on current projection parameters (30) of the projection (P), therein, camera images (23, 24) of the camera (9) are transformed. Motion vectors are determined from it. For at least one geometric characteristic of the motion vectors, a reference value is set. From a difference between the at least one geometric characteristic of the motion vectors and the respective corresponding reference value, an error value is determined. Depending on the error value, new projection parameters are determined (30).
