Application of image processing methods for the detection of specific surface structures and error patterns on tape surfaces


Short description:

The product range of Salzgitter AG in Salzgitter includes flat steel products, which are produced by hot or cold rolling. These are examined with cameras and automatic inspection systems for surface defects. The result is a list of detected errors, which like a map can be displayed graphically.
goal of this work is to determine from the error lists characteristic patterns and error distributions to check for plausibility and possibly to change the original error term. For this purpose, initially characteristic error distributions to find. The composition of the error distributions and any neighborhood relationships between the respective individual errors and groups should be analyzed with statistical methods. This rules are to be determined, which assign the detected errors groups with sufficient security specific error types.

These rules are then implemented in software and applied to the inspection results and error lists stored in a database. Special software packages for statistical analysis and for the creation of rules are available and can be used.
