摘要
三维激光扫描技术可以高精度、海量、快速地获取被测对象的三维坐标,构建出被测对象精准的三维立体模型,这种高精度的三维立体模型在各个行业有着广泛的用途。然而轮廓线提取精度是三维立体模型制作精度中起决定性因素之一。本文采用RIEGL VZ-1000三维激光扫描仪,对重庆人民大厦进行了扫描,研究了建筑物扫描点云间隔设置和轮廓线拟合提取方法。
3D Laser Scanning Technology cans high-accuracy, magnanimity,fast get object＇ s 3d coordinate, and es- tablish precise 3d model of object,precise 3d model is widespread used in all walks of life. But contour line extraetion accuracy is decided to one of the factors in 3d model making preeision. This paper used RIEGL VZ-1000 3d laser sean- ner to scanning the people of Chongqing building, research the method of building scanning the point cloud interval set- ting and contour line extraetion.
