Surface Quality Inspection

A groundbreaking innovation in real-time intelligent automated vehicle painted surface inspection system.

Detecting surface defects on a coated sheet metal is always a difficult task for the industry. Waviness, scratches, discoloured specks are all very hard to spot even by skillful quality inspection personnel. Traditionally such an inspection relies on human eyes to pick up the blemishes. However, sometimes only when the sheet metal is on a certain angle can the defects be seen by the bare eye.

We have successfully automated such an inspection process in a reliable and economical method. By applying multiple-camera to scan the complete surface in real-time, PC-based machine vision system with a special light scheme, the aforementioned surface defects became detectable. The special lighting layout makes the inspection reliable without the need to constantly adjust the camera-object relative angle.

rejected by consumers than minor technical defects"
