Metadata Specification of Railway Video Information and Its Application in Video Monitoring System for Qinghai-Tibet Railway
The lack of homogeneity in description elements and description method leads to video information sharing and management in the relative video application and management system for more management departments at all levels hampered. Based on the relevant metadata standards and the metadata technique, we put forward the railway video metadata specification, which consisted of mandatory elements, optional elements and extension elements, and the feasible method of key-frame and time- point. Then we apply the metadata specification in video monitoring system for Qinghai-Tibet railway. In this system, combined and matched the real-time video capture with the existing cataloging video, the video information is described accurately and displayed immediately. These works lay the foundation for building a normative video information management system and establish norms of video metadata cataloging to meet individual application requirements, improving the resource efficiency of the national railway video.
