There are some problems in traditional digital measurement methods such as low efficiency and heavy workload in measuring ancient buildings.In this paper,three-dimensional laser scanning technology is proposed to obtain detailed data of buildings and realize three-dimensional visualization.The key technologies of three-dimensional laser scanning technology,such as point cloud mosaic,denoising,and simplification,are analyzed.The results show that three-dimensional laser scanning technology can quickly and accurately obtain the indication information of complex buildings,and can realize two-dimensional data extraction through three-dimensional models,and the accuracy meets the requirements of specifications.
