A system is described for determining an imaging deviation of a camera having: the camera, which is focused on a first distance, having a target pattern unit, which is situated at a second distance from the camera in a field of view of the camera and which has a three-dimensional surface texture having calibration markings, having a lens unit which is situated at a third distance from the camera and between the target pattern unit and the camera and is developed so that the three-dimensional surface texture is able to be imaged by the camera, and having a control unit that is connected to the camera and which is developed so that the imaging deviation of the camera is determinable by evaluating an image taken of the calibration markings of the three-dimensional surface texture. Also described is a method for determining an imaging deviation of a camera.
