三维激光扫描技术在喀斯特洞穴测绘中的应用

Application of 3D Laser Technology in Karst Cave Mapping

针对喀斯特洞穴内部能见度低,通风条件差,不具备通信条件;外加地形多样,环境险峻,地下暗河错综复杂,洞穴测绘工作涉及高危与极端环境。文章以某喀斯特洞穴的测绘生产项目为例,研究三维激光扫描技术在喀斯特洞穴测绘中的应用,制作洞穴内部漫游视频、洞穴主线的总览图、剖面图,并计算主要洞厅的容积。实践表明,在喀斯特洞穴的测绘应用中,三维激光扫描技术速度快、效率高,有利于安全生产,且成果精度高并被广泛应用。

Due to the low visibility,poor ventilation conditions and lack of communication conditions in karst caves with diverse terrain,steep environment,and complex underground rivers,the cave mapping involves high-risk environment.Taking the surveying and mapping production project of a karst cave as a case,this paper studied the application of 3D laser scanning technology in the surveying and mapping of karst cave,made the roaming video inside the cave,the general map and section of the cave mainline,and calculated the volume of main cave hall.The practice shows that the application of 3D laser scanning technology in the surveying and mapping of karst cave is fast and efficient,which is beneficial to safe production.And its results of high precision can be widely used.
