| Abstract: | To verify the applicability of 3D laser scanning technology in measurement of urban underground space in Xining City,in this paper,the process and method of its application process were discussed. The accuracy of 3D laser scanning system was evaluated by the coordinate comparison method. The results show that the plane accuracy of the three-dimensional laser scanning system reaches 0.032 m,which is in line with the requirements of urban measurement specifications. It shows that the three-dimensional laser scanning technology has a good applicability in urban underground space measurement and can be popularized and applied. |
