Abstract:

Spatial similarity relations are a fundamental theory for multi-scale representation of spatial data. The evolution of basic spatial data from 2D to 3D has presented new challenges for research on spatial similarity relations. In this study, the concept of 3D spatial similarity relations is proposed, and a quantitative calculation method for 3D spatial similarity relations based on visual perception is further proposed to address the limitation of scale effect. First, building upon spatial similarity relationships in multi-scale maps, we define 3D spatial similarity relationships and summarize the challenges encountered in extending from 2D to 3D. Then, by comprehensively considering the attributes of 3D spatial data, the rendering mechanisms of 3D models, and the principles of human visual perception, an in-depth analysis of the visual perception processes, mechanisms, and characteristics of 3D spatial similarity relations is conducted. Following this, a reverse calculation strategy informed by visual perception is introduced, which converts complex calculations in 3D space into equivalent operations within 2D screen space, thereby enabling the quantitative measurement of 3D spatial similarity relations. Experimental results and practical applications demonstrate that the proposed method enables scale-adaptive quantitative calculations of 3D spatial similarity relations and offers valuable support for level of detail (LOD) construction and continuous visualization of 3D building scenes.
