Low-Cost Fastener Inspection System on High-Speed Railway
The demand for the high-speed fastener inspection technology has increased greatly as the train speed is growing up. A low-cost high-speed fastener inspection system was proposed in this paper. By using motion image and direction field, the proposed inspection system takes some advantages of current methods, and has the features of depth insensitive and high contrast with background.Our experimental results show that this system is a potential solution for high-speed fastener inspection.
