Railway track identification and tracking inspection method based on multi-source remote sensing image fusion

Along with diversified development of train and railway technologies, more and more types of rail transit are presented, and the rail transit is not only spread all over long-distance land transportation, but also widely applied to middle and short-distance urban public transportation. In order to guarantee operation safety of rail transit, operation maintenance needs to be conducted on rails, surrounding environments and the like regularly. The invention provides a railway track identification and tracking inspection method based on multi-source remote sensing image fusion. The problem that high efficiency, high precision, reliability and economical efficiency cannot be achieved at the same time in an existing railway track identification technology is solved. 随着火车和铁路技术的多元化发展，轨道交通呈现出越来越多的类型，不仅遍布于长距离的陆地运输，也广泛运用于中短距离的城市公共交通中。为了保证轨道交通的运行安全，需要定期对轨道、周边环境等进行运行维护。本发明提供一种基于多源遥感图像融合的铁路轨道识别及追踪巡检方法，解决现有铁路轨道识别技术中高效性、高精度、可靠性、经济性四者不可兼得的问题。
