Abstract:

The empowerment of digital twin city construction by AIGC technology has emerged as a future development trend. This paper delves into the distinctions and connections between AIGC technology and digital twin technology. It outlines the role mechanisms of AIGC technology in empowering digital twin city construction, focusing on four main directions: perception network, data model, digital twin map, and simulation application. This paper combines theoretical analysis with practical applications in four aspects of city modeling twins, urban planning and design, urban governance, and urban service. Additionally, this paper puts forward development path suggestions from five perspectives including technology research and development.

Key words: AIGC, digital twins, city, perception, data, modeling, application
