| 摘 要： | 随着信息技术和测绘科学的迅猛发展,传统的空间数据获取模式已经不能满足现在的信息化需求。三维激光扫描技术的出现,推动了现代化测绘技术的发展,其高精度、快速的非接触式扫描测绘方法改变了传统空间数据采集模式。古建筑文化遗产的三维数字化保护是目前社会的研究热点,利用三维激光扫描技术来重建古建筑独特复杂的表面模型,为古建筑数字化管理和修复提供数据参考是一个很有意义的事情。本文以利用地面三维激光扫描系统构建古建筑三维模型为研究对象,通过洞窟类实例对古建筑点云数据处理和NUBRS三维模型复杂曲面重建技术进行研究与探讨。

| Abstract: | With the rapid development of information technology and science of Geomatics, the traditional spatial data acquisition mode have already couldn't meet the demand of today's information.With the emergence of 3D laser scanning technology, the development of modern Geomatics has been promoted, and the traditional spatial data acquisition mode of Geomatics has been changed by the high precision and fast non-contact scanning method.3D digital protection of cultural heritage of ancient architectures is a hotspot of social, and it is a very significant challenge in digital management and providing data reference for repair by reconstruct ancient building complex and unique surface model using 3D laser scanning technology.In this paper, 3D model of ancient cultural relics of the ancient building constructed by 3D laser scanning system has been taken as the research object, point cloud data processing has been done with examples, and as well as the NUBRS 3D model surface reconstruction technology has been done a comprehensive research and discussion. |
