With the rapid development of railroad transportation in recent years, the traffic safety and maintenance decisions put forward more and more stringent requirements. Due to the harsh environment and other factors, railroad fasteners often break or miss. This poses a threat to railroad safety. Therefore, railroad fastener status detection is one of the important means to ensure the safe operation of the railroad, and the identification of railroad fasteners is the important technology of railroad fastener status identification. In the paper, a fastener identification method based on two-stage positioning is proposed. In the first step, the paper identifies the steel rails and rail sleepers, and then roughly locates the fasteners according to the relative position relationship of the steel rails, rail sleepers and fasteners. In the second step, our method integrates the area statistics algorithm and the template matching algorithm to achieve the precise positioning of fasteners. The experimental results show that our proposed method can effectively identify fastener.
