The Challenge:

To be able to detect and identify the braille characters marked on the surface of a metal plate.

Our Solution:

The braille alphabet was pre-programmed into the database for reference once the characters were identified with the machine vision system and lighting solution. Using a Dark Field Lighting Technique we were able to identify the braille characters on the surface of the product. The light does not fall directly onto the objective and the majority of the region of interest is dark, while the affected areas on the surface, the braille characters, appear bright. Once the impressions were identified and segmented, they were then referenced to the database and the string of characters were identified.
