Casting numbers reading system

When creating numbers on molded parts, the quality of the numbers both during the casting process as well as during eventual sandblasting can be severely impaired.

An image processing system for the detection of these casting numbers must therefore meet the highest standards.

For these special requirements was first developed by visolution its own font to ensure the largest possible constancy during the casting process and thus allow a clear identification of the pleading.

The visolution-system recognizes the casting numbers easily and independent of:

background: e.g. black text on a black background,
font quality: e.g. writing bursts,
character size: even the smallest differences in height can be distinguished,
test position: test parts can be recognized in any position.

Thereby the visolution system has an attractive user interface that enables the teaching of different writing variations in a simple way.
