Application and Solution

After the painting process, polymer parts are subjected to fully automated surface inspection by a shape-from-shading system prior to further processing. This method reliably detects the smallest surface defects such as paint pecks, scratches, inclusions, lint, or other raised or recessed defects.

 

For this purpose, our system uses eight illumination directions with corresponding eight partial images, which are computed by Shape from Shading to form a height map of the surface. The evaluation is done in the powerful image processing software VisionCommander®.
