基于三维激光获取点云的三维模型构建

Implementation research on the 3D model construction of the point cloud based on 3D laser

目前国内对一些大型古建筑文化遗产的传统测量方法往往难以获得十分准确的数据信息,这使得专家们在对一些大型古建筑进行修复时十分头疼。而且在用一些传统测量方法的测量过程中也存在对古建筑造成二次伤害的风险。现如今,随着科研技术的发展,激光扫描硬件的总体水平也在不断地进步[1]。因此,三维激光扫描技术也越来越成熟。三维激光扫描仪在一些大型建筑的测量工作中使用得也越来越广泛。三维激光扫描仪的工作原理,是先对获取到的点云数据采取配准拼接处理,再对其进行去噪简化等操作,最后利用建模软件3DMAX对大型的古建筑进行三维模型的构建的过程。

At present,the traditional measurement methods of some large ancient architectural heritage are often difficult to obtain accurate data information,which makes experts feel headache when they are restoring some large ancient buildings.Besides,the use of some traditional measurement methods could cause some damage to the ancient buildings. Nowadays,with the development of scientific technology and the improvement of laser scanning hardware and data processing methods,the technology of 3D is more and more widely used in the measurement and the restoration of some large buildings.According to the working principle of 3D laser scanner,the point cloud data is used to register the splicing processing,and then the data will be denoised. Finally,3D modeling of large ancient buildings can be constructed by modeling software 3DMAX.
