ABSTRACT

Based real-time geographic information technology, the measurable elements of the track maintenance, signals and contact line are analyzed in Beijing National Railway Track Test Center of the Chinese Academy of Railway Sciences. The technology of mobile measurable real image acquisition is studied. A real-time and accurate measurement technique for railway elements spatial location is proposed. Based on the measurable real geographic information technology, the loop railway digital platform is built. The rapid inspection and change detection of railway infrastructure has been realized. The visual comprehensive management and statistical analysis of railway infrastructure have been completed.
