Aiming at the demand of fine 3D modeling of traditional cultural architecture,this paper takes Gaogulou in the north urban area of Hongta District,Yuxi City,Yunnan Province as an example,uses nap-of-the-object photogrammetry technology to obtain high-resolution images through multi-angle detection by UAV,establishes a fine 3D model of Gaogulou,and analyzes the effect and accuracy of the model.The research shows that the technical method can effectively obtain high-quality image data,establish a fine 3D real scene model,realize the dynamic and multi-dimensional detail display of traditional cultural architecture,and provide technical support for the establishment of digital archives of traditional cultural architecture,which has broad application prospects.
