TIGHTENING INSPECTION SYSTEM FOR HIGH STRENGTH BOLTS USING RECOGNITION AI TECHNOLOGY

Abstract

The inspections of tightening completion of high-strength bolts have been conventionally conducted by visually checking all the bolts. In this study, an inspection system using image recognition AI technology was developed. This system automatically identifies the fastening completion status based on still images captured by a smartphone. We conducted a demonstration experiment using this system and confirmed that the system can accurately identify the fastening completion status, and that it is effective in improving efficiency.
