A method for the analysis of a running surface of a tire and to the type identification of a tire

摘要

A method and device for the analysis of the tread of a tire, which, to an evaluation of the status and type identification of the tire enable. According to the invention, the method by means of a twisting device, a laser scanner, and an evaluation unit, wherein from a section of the running surface line by line from the laser scanner surface profiles are produced which, from the evaluation unit to a three-dimensional image are assembled and from the three-dimensional image is generated a two-dimensional tread design. On the basis of a two-dimensional tread designs a profile reference pattern is generated and stored in a database. tread designs produced in each case be checked to match the profile reference pattern, so that in case of a match the tyre type data can be output is achieved and thus a type identification. The apparatus has according to the invention a twisting device, a laser scanner and an evaluation unit, whereby the evaluation unit in particular a mustererzeungungs- and has -erkennungsmodul.
