Urban visual perception (UVP) plays a critical role in shaping residents' quality of life by influencing their emotional and cognitive responses to urban environments. Previous studies have analyzed UVP using street view imagery (SVI) but have largely overlooked its spatiotemporal evolution and inequalities within walkable travel ranges. This study introduces a novel methodological framework using Hong Kong as a case study to analyze UVP changes from 2011 to 2021. We first identify static and dynamic UVP distributions, then explore spatial patterns across urban forms, housing types, and travel distances, and finally examine links between UVP changes and socioeconomic factors. The findings show that while Hong Kong's overall UVP levels remained stable, significant spatiotemporal disparities emerged. Public housing policies improved UVP for some disadvantaged groups, but low-income private housing areas in Old Town faced poorer visual environments with lower greenery levels. Socioeconomic factors, including education and income, significantly influenced UVP transitions, with elderly and ethnic minority populations experiencing greater environmental inequalities. This study offers micro-level insights into urban planning and renewal, providing a scientific foundation for promoting equitable urban development.
