1. A system, comprising:
a mobile part movable along a coding region and including a camera connected to an evaluation unit of the mobile part, the coding region including successively arranged coded regions, each coded region including a code; and
a one-part or multi-part cover that covers the code of at least one of the coded regions;
wherein the evaluation unit is adapted to temporally recurrently determine a deviation of a first coded region with respect to a viewing direction of the camera and/or to a straight line aligned in parallel with the viewing direction of the camera and passing through a central point of an image sensor of the camera and/or to a reference point arranged in the coding region and movable relative to the mobile part.
