基于关节臂和高清摄影进行重庆大足千手观音现状信息留取和精细三维重建具有现状的真实、完整记录，可为现场修复提供参考，为此，提出一种新的基于关节臂高精度扫描的文物精细三维信息获取方法，利用关节臂对文物进行扫描，获得高精度几何数据，在此基础上建立超精细三维建模，同时利用人工选取控制点来获取高分辨率影像。基于本方法所获得的精细三维信息可以用于三维统计、虚拟修复和变化检测等方面，为文物的现场保护修复工作提供科学依据，并为其他文物精细三维重建提供参考。最后以重庆大足石刻造像为例，验证了该方法的可行性与有效性。

This paper presents a new method to obtain three- dimensional （3D） highly detailed documentation of cultural relics. The thousand -hand bodhisattva was scanned by an articulated arm scanner and was recorded using a high- resolution camera. The information was used to construct a 3D model that reflects completely the current condition, thereby providing an aid for on - site conservation. First, the cultural relics can be scanned precisely using the articulated arm scanner and, based on the high accuracy geometric data, a detailed 3D model can be made. Then some points are selected for high -resolution image scanning. The 3 D data and detailed modeling can provide useful information for statistic studies, virtual restoration and long -term monitoring. The data also provides scientific information for on - site conservation. The application of this method on Dazu Thousand - hand Bodhisatt- va is discussed in detail. The method was shown to be feasible and efficient, providing a good example for 3D docu- mentation of other relics.
