| Abstract: | The increasing number of rail transit and the effective improvement of its running speed undoubtedly put forward higher requirements for the quality of rail construction projects.Based on this,a method of metro engineering measurement supported by 3D laser scanning technology is proposed.On the basis of ground object extraction and rendering,point cloud data collection is completed to automatically generate the center line of the tunnel,and then fine 3D modeling is realized.According to the comparison of experimental results,the metro engineering measurement implementation method proposed in this paper has a greater advantage in measurement accuracy compared with the traditional method.The experiment proves that the method proposed in this paper has higher practicability and effectiveness. |
