Abstract: In view of the characteristics of the large-scale ancient buildings, such as narrow and high single building, flexible decorative components, single modeling technology is difficult to establish a comprehensive electronic file of the three-dimensional model of the large-scale ancient buildings. In this paper, Yueling "Xiaoyi Kefeng" memorial archway in Yueling village, Guanyang county, northern Guangxi is taken as the research object, and a three-dimensional model reconstruction method based on air ground multi-data mutual auxiliary fusion is proposed. With the help of oblique photography and three-dimensional laser scanning, and the ground close range multi-perspective photography as the auxiliary collection scheme, a complete and fine three-dimensional model electronic file of large-scale ancient architectural relics is reconstructed, and the data processing fusion deviation verification, model integrity analysis and accuracy evaluation before and after data fusion is completed. This method can provide a new idea for the establishment of large-scale ancient building archives, and has a wide application prospect in the development of cultural relics protection.

Key words: space to ground assistance, 3D scanning, multi-data fusion, 3D reconstruction, large scale ancient building
