Research on Digital Twin City Platform Based on Unreal Engine

This paper focuses on the architecture of digital twin city platform based on UE4. The architecture is divided into three parts: access layer, rendering layer and service layer. The access layer provides access of 3D models and sensors. The rendering layer realizes 3D scene construction of the city, providing users with a real-time rendering 3D environment. The service layer provides data mapping and intelligent services combined with AI technology. This paper adopts B/S architecture to realize the interaction between Web and 3D virtual scene. It can be applied to traceability, monitoring, prediction and management of cities.
