【摘要】:三維激光掃描技術(shù)在地貌特征提取方面能夠?qū)崟r(shí)、主動(dòng)、高效完成數(shù)據(jù)采集工作,具有傳統(tǒng)測量方法不具有的特點(diǎn)。利用研究區(qū)點(diǎn)云數(shù)據(jù)生成等高線和三維模型可以真實(shí)地反映出其地貌特征。本文選擇李莊采石場為研究對(duì)象,利用徠卡C10掃描儀獲取激光點(diǎn)云數(shù)據(jù),采用Cyclone和Geomagic Studio軟件相結(jié)合對(duì)其進(jìn)行預(yù)處理,再分別利用Cyclone、CASS、Surfer 3種軟件提取地貌特征,并與常規(guī)測量方法進(jìn)行了對(duì)比分析。研究結(jié)果表明:3種軟件均可以生成等高線并生成理想的三維模型,且均有其特性;在制作精度和效率方面,利用點(diǎn)云數(shù)據(jù)繪制出的等高線相比常規(guī)測量方法有著明顯的優(yōu)勢。
[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.
