【摘要】：三维激光扫描技术在地貌特征提取方面能够实时、主动、高效完成数据采集工作,具有传统测量方法不具有的特点。利用研究区点云数据生成等高线和三维模型可以真实地反映出其地貌特征。本文选择李庄采石场为研究对象,利用徕卡C10扫描仪获取激光点云数据,采用Cyclone和Geomagic Studio软件相结合对其进行预处理,再分别利用Cyclone、CASS、Surfer 3种软件提取地貌特征,并与常规测量方法进行了对比分析。研究结果表明:3种软件均可以生成等高线并生成理想的三维模型,且均有其特性;在制作精度和效率方面,利用点云数据绘制出的等高线相比常规测量方法有着明显的优势。
[Abstract]:Three-dimensional laser scanning technology can be used to extract geomorphological features in real time, actively and efficiently, which has the characteristics that the traditional measurement method does not. Using point cloud data to generate contour lines and 3D models can truly reflect the geomorphological characteristics. In this paper, the Li Zhuang quarry is chosen as the research object. The laser point cloud data are obtained by using the Leica C10 scanner. The laser point cloud data are pretreated by Cyclone and Geomagic Studio software, and the geomorphological features are extracted by using Cyclone Cass surfer software respectively. The results are compared with the conventional measurement methods. The results show that all three kinds of software can generate contour lines and generate ideal three-dimensional models, and all have their own characteristics, and the contour lines drawn from point cloud data have obvious advantages over conventional measurement methods in terms of manufacturing accuracy and efficiency.
