Abstract
En 中文
Maintaining the integrity of bolted joints is vital across engineering domains. Bolt loosening under dynamic loads can compromise structural safety. We present a robust neural approach using YOLOv11 for detecting loosening through pose-based estimation of nutbolt relative rotation. A dataset of 419 bolt images and 385 nut images supports training and evaluation. The method achieves an average relative angular error of 0.94 with prediction confidence up to 98%, and remains reliable under challenging illumination, with a maximum error of 3. This innovative approach offers a highly reliable and accurate tool for monitoring bolt loosening, even detecting minute rotational movements, thereby enhancing the safety and reliability of bolted connections in diverse engineering structures.
