Fully Automatic Surface Inspection for Shiny Components

For this purpose, a reflected fringe pattern is recorded and evaluated by several cameras. The object geometry is reconstructed from the recorded image sequence and compared with the CAD model. At the same time, the sensor detects local unevenness and cosmetic defects on the surface such as paint defects, inclusions, scratches or orange peel. All defects are classified and documented. The conclusions drawn from this (Which defects occur most frequently? Where do defects occur? When do defects occur?) enable fast process adjustments and high productivity. Due to short measuring times and parallel measurements, the system achieves a high cycle rate.
