Abstract

Tunnel digital operation and management have many disadvantages such as video fragmentation, separation of video and business data, and lack of twodimensional (2D) and threedimensional (3D) linkage response methods. As a result, an innovative application method is proposed for tunnel smart operation management based on 3D video fusion. (1) The stateoftheart and needs of video applications in tunnel operation and management are analyzed to provide a direction for the application and innovation of 3D video integration technology. (2) A 3D tunnel model is constructed using building information modeling and point cloud reconstruction technology to form a static model foundation of virtual and real integration for the tunnel. (3) A method of 3D registration and virtualreal fusion rendering is proposed to fuse multichannel video and 3D scenes in real time. (4) The multisource Internet of Things sensor data are converged and fused into the fused 3D scene to form a digital twin scene that is the same as the real tunnel traffic operation scene. (5) Video fusion scenarios are used to develop 2D and 3D linkage tunnel operation management application methods such as tunnel smoothness, accident rescue, facility management, and emergency response. The results demonstrate that the recommended methods can aid in the realization of more realtime, efficient, and intelligent tunnel management and services.

Key words： virtual and real integration; threedimensional video integration; operation management; digital twin; tunnel traffic
