| 输电线路杆塔倾斜度是线路设计与运维均需考虑的重要参数之一，便携高效地实现输电线路杆塔倾斜度的精确测量和数字化描述，具有重要的价值。鉴于现有测量方法的不足和地面三维激光雷达技术的特点，提出了基于地面三维激光雷达实现输电线路杆塔倾斜度测量的新方法，搭建了试验系统，并基于搭建的试验系统开展了现场可行性与对比测试。现场可行性与对比测试结果表明基于地面三维激光雷达不仅能正确地实现杆塔倾斜测量，而且现场测试强度低，测量精度与全站仪测量法精度相当，满足工程测量需求；通过对目标对象的三维虚拟重构，地面三维激光雷达测量方法实现了测量结果可视化化和数字化描述，便于存档和追溯校核；所搭建的测试系统可用于实际工程测量。 |

| Tower inclination is one of the important parameters to be considered when designing and maintain the transmission line. It has great value to realize accurate measurement and digital description of tower inclination with portably and high efficiency. Considering the deficiency of existing measurement methods and the feature of terrestrial 3D lidar, a new method to measure the tower inclination based on terrestrial 3D lidar is proposed in the paper, and a testing system is established. The field feasibility test and comparison test are carried out based on the developed test system. The test results show that accurate measurement of tower inclination can be realized with less field labor, and its measuring accuracy is as good as total station’s which can meet the needs of the engineering survey. The measurement result can be presented with visualization and digitization by 3D modeling of target object based on terrestrial 3D lidar. This method makes it easy to keep in the archives, to retrospect and to check. What’s more, the developed test system can be used when doing the actual engineering survey. |
