1. A method for calibrating a dynamic vision sensor (DVS) camera, the method comprising:

  • detecting a two-dimensional imaging trajectory of a moving calibration object by the DVS camera;

    detecting a three-dimensional reference trajectory of the moving calibration object by a detection device that determines the reference trajectory on the basis of a plurality of accelerations of the moving calibration object at a plurality of detection times and corresponding calibration object positions, as measured by an acceleration sensor on the moving calibration object and received by the detection device from a transmitter on the moving calibration object, the imaging trajectory representing a trajectory of the calibration object imaged in image coordinates of the DVS camera and the reference trajectory representing the trajectory in world coordinates;

    reading in the imaging trajectory and the reference trajectory by an interface device that supplies the imaging trajectory and the reference trajectory to an ascertainment device that includes a processing unit; and

    calibrating the DVS camera by the ascertainment device on the basis of the imaging trajectory and the reference trajectory.
