3D-Watch Lower Case Glue Path Inspection

Pain point: 

In the assembly process of smartwatch, the state of glue application (leakage, broken glue, glue bias, glue height over the limit, etc.) will affect the assembly quality of the product, and the traditional algorithms can't differentiate the color of the glue and the product when the color of the glue and the product are close to each other, so it is impossible to achieve stable detection.

Advantage: 

It can realize the extraction of glue path by height, width and volume information, which greatly improves the stability of detection.
