Abstract: The level of railway operation and maintenance management directly affects the efficiency and quality of transportation dispatching, safety production, and daily management. In view of more and more use of BIM Technology to build operation and maintenance management platform in current operation and maintenance management, this article put forward the application scheme of daily operation and maintenance BIM creation and update based on 3D reconstruction technology, and applied 3D reconstruction technology and BIM technology to operation and maintenance management information system. By comparing different imaging technologies, the article proposed a method to update BIM operation and maintenance model by using structure sensor 3D scanning equipment and 3D reconstruction technology, so as to improve the efficiency and quality of operation and maintenance management.
