A confirmation of final tightening of bolt is peformed by practicing engineers. They check a marking on the each bolt to judge a tightening correctly performed. However, this procedure has some problems. 1) The huge number of bolt requires many time to be confirmed by an engineers and 2) the objective record of the confirmation of all bolt are not remain.
We propose an automatic confirmation system of final tightening of each bolt using deep learning based image processing method. The system receives the movie of bolt tightening area as input. At first step, the system detects each bolt in the movie and clips images of one bolt. Next step, the system detects marking on the bolt from the clipped images. Last step, the system judge detected marker means correctly fasten of each bolt or not. We conducted the experiment of the system with the movie of real bolt tightening area. The results show some problem at shooting a movie in real circumstance and we discussed these problem.
