三维激光扫描仪在红色古建筑建模的应用 ——以龙江书院为例

红色古建筑因其形状独特、结构复杂,传统的测绘方法难以精确还原其真实空间三维场景。三维激光扫描仪能完整的获取红色古建筑的整体结构和细节形态特征,快速、自动、准确地获取目标物体表面的点云信息,具有传统测量无法比拟的优势。运用天宝TX8三维激光扫描仪,以井冈山市的龙江书院为研究对象,阐述红色古建筑的外部和内部点云数据采集和处理,提出一种分步的古建筑精细模型的三维重建方法,探讨了三维激光扫描技术在古建筑建模中的应用。结果表明:三维激光扫描技术能够极大节省工程时间,提高测量精度,降低数据处理的复杂程度,能够快速、精确的获得红色古建筑的三维模型,为红色古建筑三维重建提供借鉴和参考。

APPLICATION OF 3D LASER SCANNER IN RED ANCIENT ARCHITECTURE MODELING: A CASE STUDY OF LONGJIANG ACADEMY

Duo to red ancient architecture''s unique shape and complex structure, the traditional surveying and mapping method is difficult to accurately restore its real space three-dimensional scene.The 3D laser scanner can get the whole structure and the detailed shape characteristic of the red ancient building, get the point cloud information of the object surface quickly, automatically and accurately. In this paper, using Trimble TX8 3D laser scanner, taking Longjiang academy in Jinggangshan as the research object, the data acquisition and processing of the facade of the exterior and interior of red ancient buildingsare analyzed, and a step-by-step method for three-dimensional reconstruction of fine models of ancient buildings is proposed. The results show that the 3D laser scanning technology can greatly save the engineering time, improve the measurement accuracy and reduce the complexity of data processing, which provides reference for three-dimensional reconstruction of red ancient buildings.
