基于三维激光扫描的古建筑文物三维数字化保护研究——以四川乐山文庙大成殿为例

Digital Protection of Ancient Cultural Relics Based on 3D Laser Scanning:A Case Study of Leshan Confucian Temple

三维激光扫描以其数据获取的速度快、精度高、无接触等优势,为古建筑文物的数字化保护提供了一个有效途径。本文以四川乐山文庙大成殿为例,用地面和手持式三维激光扫描仪开展点云数据获取,构建了文物三维数字化档案,进而开展三维重建和信息提取,对研究技术路线、数据采集、数据处理、三维模型构建相关技术和方法进行了详细阐述。

Because of data acquisition speed, high precision, non- contact and other advantages, the 3D laser scanning technology provides an effective way for digital protection of ancient cultural relics. The article takes Leshan Confucian temple as a case study, use the ground and portable 3 D laser scanner to capture point cloud data, structure digital archives of the cultural relics, and carry out 3D reconstruction and information extraction. Through indepth analysis of data acquisition, data processing, and 3D model construction technology and method.
