Abstract

A device for measuring the tread depth of a tire includes measuring modules situated transversely with respect to the running direction of the tire and connected to a shared evaluation device. Each measuring module includes (i) an illumination device which is configured and situated in such a way that during operation it projects at least one light line onto the tread to be measured, and (ii) at least one image recording device recording at least one image of at least one area of the tread to be measured. The at least one illumination device and the at least one image recording device are configured and situated in such a way that the illumination direction of the illumination device and the image recording direction of the image recording device are oriented neither in parallel to one another nor orthogonally with respect to the tread.
