What are the surface defects of industrial vision inspection?

Industrial vision inspection is a method to detect and identify product surface defects by using computer vision technology. Common surface defects include the following categories:

1. Scratch: A linear defect caused by the surface being scratched or rubbed by a sharp object.

2. Bottom leakage: the coating is uneven, and some areas are missing or not completely covered.

3. Spots: Small spots with sudden changes in surface color and brightness.

4. Bubble: A circular or elliptical bulge appears on the surface of the object, and there is air or other gas inside.

5. Pit: There are obvious depressions or pits on the surface of the object.

6. Stains: Impure substances such as foreign bodies, stains or oil stains appear on the surface of the object.

7. Loss/fracture: the surface of an object is missing or obviously fractured.

These are just some common types of surface defects, and there may be other types of defects in practical application. Industrial vision systems usually use image processing algorithms and models to automatically detect and classify these defects, and generate corresponding reports for further processing.
