摘要
为验证三维激光扫描技术在西宁市城市地下空间测量中的适用性,探讨了其应用过程的流程和方法,用坐标对比法评定了三维激光扫描系统的精度。结果表明:三维激光扫描系统的平面精度达到0.032 m,符合城市测量规范要求,说明三维激光扫描技术在城市地下空间测量中具有很好的适用性,可以推广应用。
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.
