Method and system for the automatic optical inspection of a tread profile of at least one wheel of a vehicle

摘要

A method for the automatic optical inspection of a tread profile of at least one wheel of a vehicle is provided, the method encompassing the following steps: Irradiating at least one section of the tread profile using radiation from at least one radiation device; detecting the radiation reflected by the tread profile using at least one radiation detection device; processing the reflected radiation using a data processing device; and outputting an analysis result regarding a two-dimensional and/or three-dimensional structure of the tread profile, i.e., for suitability for winter weather road conditions.

1. A method for automatic optical inspection of a tread profile of at least one wheel of a vehicle, comprising:
irradiating, using radiation from at least one radiation device, at least one section of the tread profile; detecting, using at least one radiation detection device, radiation reflected by the tread profile; analyzing, using a data processing device, the reflected radiation, wherein the analyzing includes:
(a) ascertaining a two-dimensional structure of the tread profile, the two-dimensional structure including at least one of a block, a longitudinal structure, a rib, a lamella, and a tread groove of the tread profile, and(b) ascertaining a three-dimensional structure of the tread profile, the three-dimensional structure being tread depths; based on the analysis and the two-dimensional structure, selecting between a winter profile and a summer profile, and assigning the selected profile to the tread profile; determining a suitability of the tread profile for winter road conditions based on the assignment and the three-dimensional structure; and outputting an output regarding the determined suitability of the tread profile for the winter road conditions.
