Method for Calibrating an Assistance System of a Civil Motor Vehicle

A method for calibrating an assistance system of a civilian motor vehicle, comprising

• capturing image data for surroundings of a civilian motor vehicle by means of a camera device arranged on the civilian motor vehicle in an image sensor coordinate system;
• capturing depth data for the surroundings of a civilian motor vehicle by means of a depth sensor device arranged on the civilian motor vehicle, wherein the depth data indicates first distances between the civilian motor vehicle and objects in the surroundings of the civilian motor vehicle in a depth sensor coordinate system;
• deriving second distances between the civilian motor vehicle and objects in the surroundings of the civilian motor vehicle represented in the image data from the image data by means of an image analysis based on artificial intelligence in a data processing device, and creating three-dimensional image data from the image data and the second distances in a three-dimensional image sensor coordinate system;
• calibrating the image data and the depth data with respect to each other in the data processing device, comprising determining a transformation rule by means of which
• the three-dimensional image data are transformed into the depth sensor coordinate system so that the coordinates of the first and the second distances coincide in the depth sensor coordinate system;
• the depth data are transformed into the three-dimensional image sensor coordinate system so that the coordinates of the first and the second distances coincide in the three-dimensional image sensor coordinate system;
• or
• the three-dimensional image data and the depth data are transformed into a predetermined coordinate system so that the coordinates of the first and the second distances coincide in the predetermined coordinate system;
• and
• applying the transformation rule to subsequently acquired image data and/or depth data by means of the data processing device.
