摘要
地下管线是保障现代城市可持续发展的“生命线”,地下管线的准确性对大型城市的发展起到重要作用。然而常规的普查方法在精度和时效性上难以满足现有管线更新的要求,经过以车载激光扫描技术为主要测绘手段的全息测绘测试,可提高地下管线更新速度,及时捕捉管线变化,最后结合三维管线管理平台实现了地下管线的一体化更新。
Underground pipeline is the“lifeline”to ensure the sustainable development of modern cities.The accuracy of underground pipelines plays an important role in the development of large cities.However,the conventional survey method is difficult to meet the requirements of the existing pipeline update in terms of accuracy and timeliness.In this paper,the holographic mapping test with vehicle laser scanning as the main mapping means is used to improve the update speed of underground pipeline,and timely capture the changes of pipeline.Combined with the three-dimensional release,the integrated updating of underground pipeline is realized.
