中文摘要：从2004年5月开始,故宫博物院"古建筑数字化测量技术研究项目组"应用三维激光扫描技术先后对太和殿、太和门、神武门、慈宁宫和寿康宫院落等重要古代建筑进行了完整的三维数据采集,并在大量实践基础上深入研究了处理三维数据的核心理论与方法。本文系统总结了使用三维激光扫描仪获取测量数据——点云,并将点云加工成三维模型、二维线条图和正射影像图,进而应用于古建筑整体变形监测、大木结构安全性分析、建筑构件尺寸测量和外观现状记录的方法与流程。

英文摘要：Since May,2004 the research panel titled The Palace Museum Historical Architecture Digital Measurement Technology Research has started applying 3-D laser scanning technology to measure the historical buildings like Hall of Great Harmony(Tai He Dian),Gate of Great Harmony(Tai He Men),Gate of Martial Spirit(Shen Wu Men),Palace of Compassion and Tranquility(Ci Ning Gong) and the compound of Palace of Longevity and Well-Being(Shou Kang Gong).With the valuable data they gathered and practical experiment,the panel have made a more research of the central theories and methods of processing 3-d data.This paper systematically reviews the collected data—— point cloud which was proceeded into 3-D models,2-D string diagram and orthophotograph,which will be used in monitoring the condition of the whole structure of the buildings,analyzing the security of the Timber Constructions,measuring the sizes of the architecture components and approaches and procedure recording the outer situation of the buildings.
