Real-time Inspection System Based on Moire Pattern and YOLOv7 for Coated High-reflective Injection Molding Product

Abstract

Recently, with the development of smart factories, innovation through automation is being carried out in various fields of industry. In particular, because quality control requires a lot of man-hours, many studies are being conducted to replace workers with machine vision. We proposed a real-time inspection system based on YOLOv7 using moire patterns to automate quality inspection in the industry. In particular, the inspection system was successfully applied in the actual industrial manufacturing environment by overcoming the limitations of the applying inspection system to high-reflective products. Not only did we confirm the possibility of applying YOLOv7 to industrial sites, but our proposed optical system can also be used for the inspection of other high-reflective products.
