Digital Preservation of Du Fu Thatched Cottage Memorial Garden

Abstract

The Xishu Historical and Cultural Celebrity Memorial Gardens are representatives of southwestern regional gardens in China. Du Fu Thatched Cottage is one of the typical examples of these gardens, with exceptional memorial, historical, and cultural significance. However, compared to other gardens in China, few research has been conducted on their digital preservation and construction connotation. In this study, the digital model of Du Fu Thatched Cottage was obtained by terrestrial laser scanning and total station technology, and its memorial analysis and preservation were studied digitally. Using three levels of point, line, and surface analysis, we examined how to digitally deconstruct the commemorative elements of Du Fu Thatched Cottage that included the memorial theme, gardening components, and design philosophy of the garden space. The study revealed the memorial space core of the Historical and Cultural Celebrity Memorial Gardens in Xishu and proposed a strategy for building a digital preservation system. The research will help to digitally protect the Du Fu Thatched Cottage and analyze methods to memorialize other traditional gardens.
