Anhui Tongling Yangtze River Bridge

By comprehensively utilizing advanced technologies such as UAV oblique photogrammetry and laser point cloud technology, an ultra-high precision 3D visualization reconstruction of the Yangtze River Bridge at Level 4 accuracy was achieved, precisely replicating the bridge's main structure, surrounding terrain, and every detail. This 3D model of the Yangtze River Bridge not only supports 360° panoramic viewing and multi-dimensional spatial analysis but also constructs a dynamic and interactive digital twin system for the bridge. This achievement has been widely applied in various fields such as bridge health monitoring, intelligent operation and maintenance management, digital asset archiving, scientific research and teaching demonstrations, and online virtual tours, providing strong digital core support for the full lifecycle management of this important transportation infrastructure and helping bridge maintenance enter a new stage of intelligentization.

MiaoTu focuses on the digital construction of bridges, providing a full-process 3D technology solution, with core coverage including bridge 3D modeling and dedicated bridge modeling services, assisting in the intelligent upgrade of bridge operation and maintenance management. Relying on laser point cloud technology to accurately collect data on the bridge's main structure, component details, and ancillary facilities, combined with UAV oblique photogrammetry to reconstruct the overall appearance of the bridge and its surrounding environment, a high-precision 3D model of the Yangtze River Bridge was created according to the Level 4 accuracy standard, ensuring a high degree of consistency between the model and the actual condition of the bridge. Simultaneously developing a 3D visualization system and digital twin platform for the Yangtze River Bridge, coupled with 360° panoramic views, allows for a direct display of the bridge's structural health, traffic dynamics, and key maintenance areas. These digital achievements can be widely applied to scenarios such as safety monitoring, defect identification, operation and maintenance planning, and emergency drills for the Yangtze River Bridge, replacing traditional bridge management models, improving bridge operational safety and control efficiency, and providing professional technical support for the digital transformation of bridges and large-scale transportation infrastructure in the Yangtze River Basin.
