近年来,具有扫描速度快、精度高等优点的三维激光扫描技术为空间三维信息的获取提供了强有力的技术手段.文章通过研究三维激光扫描技术在世界文化遗产——开平碉楼的应用,对从点云数据获取、预处理到如何快速准确建模的完整流程进行了详细的分析并优化了技术路线,以及针对此项新技术与传统测量技术的优劣进行探讨.研究结果表明,三维激光扫描技术对古建筑的量测具有重要意义,可为广东省的古建筑修缮保护与展示提供强有力的数据支撑与技术支持,并达到真实比例的虚拟仿真三维效果.
Abstract
In recent years, 3D laser scanning technology with scanning speed, high precision provides a powerful technical means to obtain three-dimensional information space. By studying the three-dimensional laser scanning technology in the world cultural heritage Kaiping from point cloud data preprocessing to how to complete the process of quick modeling, a detailed analysis was carried out, and this paper compares the new technology with traditional measurement techniques.The results show that three-dimensional laser scanning technology has great significance to measure the amount of ancient architecture, providing powerful data support and technical support for the restoration and exhibition of ancient architecture protection and achieve the true proportions of the three-dimensional virtual simulation results.
