NPU-BOLT: A Dataset for Bolt Object Detection in Natural Scene Images. (arXiv:2205.11191v2 [cs.CV] UPDATED)

Bolt joints are very common and important in engineering structures. Due to
extreme service environment and load factors, bolts often get loose or even
disengaged. To real-time or timely detect the loosed or disengaged bolts is an
urgent need in practical engineering, which is critical to keep structural
safety and service life. In recent years, many bolt loosening detection methods
using deep learning and machine learning techniques have been proposed and are
attracting more and more attention. However, most of …
