A desmontagem automática de fixadores ferroviários é de grande importância para melhorar a eficiência da substituição de trilhos. O posicionamento preciso do fixador é o fator chave para realizar a desmontagem automática. No entanto, a maior parte da literatura existente concentra-se principalmente no posicionamento da região dos fixadores e a literatura sobre o posicionamento preciso dos fixadores é escassa. Portanto, este artigo construiu um sistema de inspeção visual para posicionamento preciso de fixadores (VISP). Inicialmente, o VISP adquire a imagem da ferrovia pelo subsistema de aquisição de imagem e, em seguida, a subimagem do fixador pode ser obtida pelo método grosso-fino. Posteriormente, o posicionamento preciso dos fixadores pode ser concluído em três etapas, incluindo aprimoramento de contraste, binarização e extração da região de pico. A validade e robustez do VISP foram verificadas por vastos experimentos. Os resultados mostram que o VISP possui desempenho competitivo para posicionamento preciso de fixadores. O tempo de posicionamento único é de cerca de 260 ms e a precisão média do posicionamento está acima de 90%. Assim, é de interesse teórico e potencial aplicação industrial.

Abstract: Automatic disassembly of railway fasteners is of great significance for improving the efficiency of replacing rails. The accurate positioning of fastener is the key factor to realize automatic disassembling. However, most of the existing literature mainly focuses on fastener region positioning and the literature on accurate positioning of fasteners is scarce. Therefore, this paper constructed a visual inspection system for accurate positioning of fastener (VISP). At first, VISP acquires railway image by image acquisition subsystem, and then the subimage of fastener can be obtained by coarse-to-fine method. Subsequently, the accurate positioning of fasteners can be completed by three steps, including contrast enhancement, binarization and spike region extraction. The validity and robustness of the VISP were verified by vast experiments. The results show that VISP has competitive performance for accurate positioning of fasteners. The single positioning time is about 260ms, and the average positioning accuracy is above 90%. Thus, it is with theoretical interest and potential industrial application.
