The Summer Palace is a treasure of the World Cultural Heritage of classical gardens. The visual perception of tourists greatly influences the inheritance of cultural heritage and the tourism charm of the Summer Palace. This study is based on visual perception, using physiological sensors and field images to determine the research scenarios of imperial poetry. Six types of perception evaluation are selected for spatial visualization. Through the comparison and analysis of the experience of visiting gardens in the Qing Dynasty from ancient to modern times, the correlation between material change factors and perception types is analyzed, and suggestions for style protection are put forward. The results show that: 1) The garden makes use of elements such as mountains, rocks, water bodies, open water surfaces, rich colors and historical scenes to highlight the soothing effect of classical gardens on the soul and the immersive historical experience. 2) By comparing the scenes in the imperial poems, it is found that the changes in the scenes of the Summer Palace are closely related to the public’s perception. The back mountain area lacks the artistic conception and characteristics of a classical garden. Plants block the view, weakening the borrowing relationship. The architectural changes have led to the disappearance of the relationship between borrowing and opposing views. Modern elements have spoiled the artistic conception of the garden. The research has proposed optimization and improvement strategies from aspects such as the optimization of plant landscapes and the enhancement of elements, the protection of external scenery and the original appearance of buildings, and the evolution of gardens and the protection of artistic conception. This article provides practical guidance for the protection, inheritance and restoration of the appearance of the Summer Palace and classical gardens, helping cultural heritage to shine with new luster in the new era.
