Design And Implementation Of 3D Smart Park System Based On Cloud Rendering

With the rapid development of the country’s digital economy and the improvement of computer graphics processing power,VR/AR and other virtual-reality technologies are being widely used in various fields.An important application area is represented by the 3D smart parks.Physical space is integrated with digital information through digital technology and intelligent devices in 3D smart parks to achieve highly intelligent management,optimization and control,improving the efficiency and competitiveness of enterprises and cities compared to traditional smart parks.Currently,there are still many issues with 3D smart park systems.When loading large-scale scene data,the speed is slow and relies on device performance and downloaded model data.Compatibility and scalability are poor,resulting in high maintenance costs for customized development.Rendering resource management is chaotic,leading to poor real-time performance.To address these issues,this paper uses the Unreal Engine as the main development platform,combined with the Cesium Earth engine and cloud rendering pixel streaming technology,to design and implement a cloud rendering-based 3D smart park system.The main work and innovations of this thesis are as follows:(1)A 3D smart park system based on cloud rendering has been designed.The roaming,billboard,annotation,data collection,and other functions have been designed for the practical application scenarios of the 3D smart park.The various functional modules are integrated with the geographic information engine to manage assets,display inspections,and prevent disasters in the park from a 3D perspective.A lightweight B/S system architecture has been designed,including the presentation layer,application layer,business layer,data layer,and transmission layer.The coordination between each layer provides stable support for the functional modules.(2)A 3D smart park system based on cloud rendering has been implemented.The rendering and display are separated through pixel streaming technology,and geographic information data is loaded using the Cesium Earth engine,allowing the system to use high-quality rendering services with low latency.When loading 10G model data with 400M bandwidth,the system can load data without relying on downloading model data and terminal equipment,and the loading speed is more than twice that of other types of solutions.The system is compatible with three types of terminal devices(mobile phones,tablets,and computers)and supports at least six mainstream browsers.The cloud rendering-based 3D smart park system designed in this paper can greatly improve the ability of managers to monitor the environment,allocate resources,and plan and design 3D smart parks,meeting the market demand for 3D smart parks.
