AUTOMATIC VISUAL INSPECTION

Area scan images or line scan images under SPECIFIED illumination

Many characteristics of the test surface are clearly visible to the camera through special illumination. These include cracks, pores, shells, cavities, dents, eruptions, roll-ins and much more. The type of illumination, whether incident or transmitted light, diffuse or directional, coloured or polarised, plays an essential role for visibility.

The intelligent and adaptive software helps to reliably differentiate between displays in defects and artefacts (false displays).

"Visual inspection" application examples
Control of ground billets

Coarsely ground surface of a billet with longitudinal crack.

This picture was taken after grinding out a crack found during the flux test. In spite of the uneven surface, the crack is identified by automatic pattern recognition without the use of test equipment and only by suitable lighting.

Graphite Electrode

Crack in a sawn graphite surface.

The software differentiates between crack indications before the clear saw marks. In spite of the dark grey surface, cracks become visible through suitable lighting, no test equipment is necessary.

Breakout on rolled steel profiles

Recesses in the hollow of a double T-beam.

After rolling, the automatic visual inspection can be carried out under special lighting directly at the roller table. The transport speed of the beam is 1.5m/sec.
