Tags on Tires

Automatic recognition of tags on tires

Tires marked with two white tags in a certain radial distance are supposed to be sorted out automatically in a production line. Different types of tires have to be covered and also the brightness of the background can vary. The recognition of the labels must fulfill hard real time and stability conditions.

The solution of this problem was implemented in the software tool box iconnect. Actually it works at Adam Opel AG.

The picture shows a screenshot of the implementation in the iconnect environment. Single modules are connected in graph of modules which defines an exectable (left side). A typical input image and the result ("2 korrekte Marken gefunden" = two correct tags detected) are shown on the left side of the picture.
