摘要: 针对中低速磁浮接触轨连接板螺钉松动识别的问题,提出一种基于YOLO v2网络和OTSU的识别方法。首先采用YOLO v2网络定位连接板,然后在连接板区域上进一步定位螺钉头部;通过OTSU实现螺钉头部和连接板边缘的精确分割,根据螺钉头部宽度归一化螺钉头部至连接板距离,以此判别螺钉状态。实验结果表明,本文方法能准确地识别连接板螺钉的松动。

Abstract: To deal with the screw looseness of connecting plate of medium and low speed maglev contact rail, a recognition method based on YOLO v2 network and OTSU is proposed. First, YOLO v2 network is used to locate the connecting plate. Then, the head of the screw is further localized on the connecting plate area. This paper uses OTSU to segment the screw head and the edge of the connecting plate. Finally, the status of the screw could be judged by the distance from the head of the screw to the edge of the connecting plate which is normalized by the width of the screw head. The experimental result shows that the method can accurately identify the looseness of the connecting plate screws.

Key words: medium and low speed maglev contact rail, screw looseness, YOLO v2, OTSU
