Deep learning and image processing based bolt loosening detection method

摘要

The present invention relates to a method for detecting bolt loosening based on deep learning and image processing, comprising: detecting a bolt image from image data using RCNN; Through the image processing technique from the detected bolt image, the initial loosening of the bolt can be detected more accurately through the configuration including the step of estimating the bolt loosening angle, the bolt image is detected from the image data through the learning algorithm, and the image processing technique is applied. It relates to a deep learning and image processing-based bolt loosening detection method that can correct perspective distortion and estimate the bolt loosening angle.
