基于3种测量技术的贵州潜龙洞探测数据对比研究

Comparative Study on the Surveying Data of Qianlong Cave in Guizhou Based on Three Kinds of Measurement Technology

指出了喀斯特洞穴测量属于一种特殊的地下空间测量。在结合贵州潜龙洞早期传统手绘测量成果的基础上,又分别采用基于移动终端的无纸化测量技术与三维激光扫描技术对其进行了重复测量,并对以上3种探测数据分别从时效性、数据精度与准确性、操作便捷性、数据存储与处理等方面进行了对比研究,总结分析了各自的优缺点及最佳适用情形,为同类喀斯特洞穴测量方案提供决策依据,以有效地保证洞穴探测及后续工作的实际需求。

Karst cave survey belongs to a special kind of underground space measurement. In this paper, the work-group adopted the paperless measurement technology based on mobile terminals and 3D laser scanning technology torepeated measurement in combination with early traditional hand--painted survey results in Qianlong cave. It respec-tively studied the comparative study above three kinds of survey data from the aspect of data precision, accuracy,timeliness, operating convenience, data storage and processing, etc. At last, it summarized both advantages and dis-advantages as well as the best suitable situation. The purpose is to provide decision basis for similar karst cave surveyscheme, thereby ensuring the cave survey and the actual demand of follow--up work.
