Abstract

With rapid iteration of digital twin and real-time 3D rendering technologies, smart campus construction is evolving from basic 2D information display to immersive service-oriented digital scenes. Traditional campus platforms based on 2D maps, static web pages and manual consultation suffer from poor spatial visualization, fragmented data and insufficient interactivity, making it difficult for teachers, students and visitors to locate facilities and complete campus services efficiently. To address these limitations, this paper proposes a university spatial service system built on Unreal Engine 5 (UE5) and digital twin. A five-layer decoupled architecture is adopted to realize bidirectional data synchronization between physical campus entities and administrative services, alongside four core modules: immersive roaming, indoor-outdoor integrated navigation, virtual-real information retrieval and one-stop service guidance. The system integrates the UE5 Navigation Mesh and MySQL database, connecting the 3D scene models with the campus business data to form a closed-loop service workflow of "inquiry-guidance-navigation". The prototype is used for comparative quantitative experiments, which can reduce the information query latency by 43.75% and the path calculation cost by 48.89% compared with the conventional 2D platform, while keeping a steady frame rate of 58-62 FPS on a common PC. This research proposes a comprehensive engineering framework for digital twin smart campus construction and extensible technical support for subsequent campus service optimization.
