Portable acquisition device and 3D spatial data management system for railway infrastructure

Aiming at the problems of lack of three-dimensional spatial data of railway infrastructure, difficulty in collection, low collection efficiency, scattered data, and difficulty in centralized management and maintenance, this paper developed a portable non-contact acquisition device based on mobile real scene measurement technology to implement a three-dimensional spatial data acquisition of railway infrastructure, and built a three-dimensional spatial data management system for rail infrastructure to implement the centralized, efficient management and storage of three-dimensional spatial data. The system used the linear reference system construction technology to realize the rapid matching of three-dimensional spatial data of railway and linear mileage coordinates. The experimental results show that the acquisition device developed and the management system built are scientific, advanced and practical, and effectively improve the acquisition efficiency and information management level of three-dimensional spatial data of railway infrastructure.
