Abstract: Visual perception in motion is an important way for observers to recognize the built environment. The development of panoramic vision technology provides new ideas for multi-perspective and quantitative studies of the influencing factors and action mechanism of garden tour experience. This research applies ecological psychology and parallel visual processing in the vision system as the theoretical foundation. It re-examines the visual perception in motion from the perspective of panoramic projection, and proposes measurement methods of dynamic visual information based on optical flow diagrams. Taking the Lingering Garden as an example, the research quantitatively and visually analyzes the patterns and characteristics of continuous changes in visual information during motion, as a reference for the research on the mechanism of garden tour experience.
