The Practice of Cross-platform Digital Twin Scene Construction Technology Based on GIS Engine and Unreal Engine Fusion

GIS Engine;Unreal Engine;visual scene construction; scene fusion;

Taking the Xinjiang Kuitun River Diversion Project for example, we constructed a refined and multidimensional visualization technology to build the dam Digital-twinning scene system to promote the intelligent management of water conservancy projects.Based on the GIS engine,a watershed scene is constructed by combining remote sensing images, digital elevation models and oblique photography models. And a refined engineering scene is constructed based on the Unreal Engine , BIM models and remote sensing images. On the above basis, precise integration of GIS engine and Unreal Engine scene visuals and high-fidelity rendering are achieved by combining interfaces and scene transformation matrices of different scenes. The above application system is expected to provides a useful references for engineering construction of the digital twin technology and promote the application of digital twin technology in water project construction.
