摘要
与传统测量方式相比,三维激光扫描技术具有更高的测量精度和测量效率,在文物保护领域的应用效果更好。本文利用三维激光扫描技术采集了福建闽越王城博物馆中各类文物数据,并结合Geomagic studio12与CloudCompare软件对点云数据进行去噪、拼接与合并,建立优化后的三维文物模型。该技术能够无接触地完成文物数据的采集,防止数据采集时对文物造成破坏,同时通过对可移动文物进行纹理处理,能够真实反映文物的个体特征,包括其色彩、形态等。结果表明,利用三维激光扫描技术所获取的文物整体模型和实物较为符合,有助于构建准确的文物数字信息档案,为文物的宣传提供形象、生动的三维模型,并为后续文物的修复和保护工作提供科学依据。
Compared with traditional measurement methods,3D laser scanning technology can get higher accuracy and efficiency,and has better application effects in the field of cultural relics protection.Therefore,this paper collects various cultural relics data from the Fujian Minyue Wangcheng Museum by using the mentioned technology,and combines Geomagic Studio12 and CloudCompare software to denoise,concatenate,and merge point cloud data to establish an optimized 3D cultural relic model.The technology can be used to collect cultural relics data in the way of noncontacting,and hence to avoid the destruction of cultural relics during data collection.Moreover,it can truly reflect the individual characteristics of cultural relics,including their color,shape,etc.after texture processing of movable cultural relics.The results show that the overall model of cultural relics obtained by 3D laser scanning technology is consistent with the real objects,which helps to construct accurate digital information archives of cultural relics,provides vivid 3D models for the promotion of cultural relics,and scientific basis for restoration and protection of cultural relics in the future.
