Abstract：Digital technology serves as an important tool for the preservation and revitalization of ancient architectural cultural heritage. Utilizing the CiteSpace analysis tool， this study systematically reviews and analyzes domestic and international literature on ancient building digitization， mapping the research hotspots and trends through a knowledge graph. Key findings are shown as follows. 1) The institutions and universities at home and abroad that have done digital research on ancient buildings denmonstrate limited cross-border collaboration， and the institutions and universities with close research collaboration on digital protection of ancient buildings abroad are mainly distributed in Italy， while those in China are mainly in Dunhuang， Gansu Province， indicating that the artistic value of ancient buildings is an important factor to promote the cooperation and exchange of digital research on ancient buildings. 2) With the advancement of time， the digital research and protection of ancient buildings at home and abroad have been deepened， and the diversity and versatility of data collection technology and digital modeling standards and platforms for ancient buildings have been gradually improved. 3) In the field of digital research of ancient buildings， foreign countries mainly focus on laser scanning technology， which extends 3D modelling， 3D scanning and other technologies， while domestic 3D modelling technology is the main one， which extends oblique photogrammetry， 3D laser point cloud and other technologies. In the process of digital research of ancient buildings， it is the focus of the future to strengthen the cooperation between domestic and foreign research institutions， combine artificial intelligence， machine learning and other technical hotspots， and expand the perspective of digital research of ancient buildings.
