Intelligent lighting design of cloud computing platform based on digital twin historic landscape blocks-Take Yu Garden commercial street in Shanghai as an example

In recent years, with the development of the Digital Revolution, information technologies such as digital twins and virtual reality are gradually penetrating people's daily learning and living environment. The digital twin historic landscape street has the performance advantages of virtual reality integration, real-time interaction, independent iteration, and dynamic perception. Taking the historical district of Yu Garden in Shanghai as an example, this paper builds a travel simulation model of the historical district based on the basic elements of the scene service of the digital twin district under the empowerment of "cloud, data and intelligence". With the digital twin lamps as the physical entity, the passenger flow dynamic simulation data model is constructed. The effectiveness of the model was verified through simulation of the impact of passenger flow changes on passenger flow, and improvements and enhancements were made to smart lighting fixtures in the block. This study explores the rich application scenarios of digital twin historic blocks and creates a scenario-based service model, which will fully activate various online and offline elements of historic landscape blocks, bringing users a brand-new immersive experience.
