| 摘 要： | 溶洞旅游是旅游行业的一个重要组成部分，其具有稀缺性与不可复制性的特点。溶洞旅游开发过程中需要注意开发与保护的统一，传统测绘手段只能为设计单位提供2D数字绘图，不能详细反映溶洞内部细节情况，因此设计单位在设计时可能出现在某些空间上把握不准确，造成空间浪费甚至溶洞内部资源损坏的情况。借助地面三维激光扫描系统，通过前期控制测量，将扫描仪安置在控制点上对溶洞内部进行高精度扫描。以云南某溶洞旅游景区开发项目为例，阐述三维激光扫描技术在地下溶洞旅游开发中的具体应用，包括前期现场准备及作业方法、点云数据处理、复杂表面3D建模、精度评定、作业效率分析及经验总结等，以期为溶洞旅游开发提供一定参考。

| Abstract: | Karst cave tourism is an important part of the tourism industry. It has the characteristics of scarcity and non-replicability. The tourism development of karst cave needs the unification of development and protection. The traditional surveying and mapping means can only provide 2D digital drawing for the design unit， which can not reflect the details of the inner part of the cave， so the design unit is set up. Timing may appear inaccurate in certain spaces， resulting in waste of space and even damage to the internal resources of the cave. With the ground 3D laser scanning system， the scanner can be placed at the control point for high-precision detailed scanning through the previous control measurement. This paper takes the development of a cave tourism scenic spot in Yunnan as an example to introduce the 3D laser scanning technology in the underground cave tourism development. Specific applications include pre-site preparation and operation methods， point cloud data processing and application， complex surface 3D modeling and application， accuracy assessment， operational efficiency analysis and experience summarization. The discussion has certain reference value for the tourism development of caves. |
