| 摘 要： | 古文物数字化保护已经成为关系全球的社会化问题。提出了一种以三维激光扫描技术和CCD摄像技术为主要数据获取手段的真三维、真尺寸、真纹理的古文物数字化工程方法。首先，对三维数据进行去除噪声和补洞等预处理；接着，利用一种改进的ICP算法，实现渐进式多视点三维数据配准；最后，由体绘制方法将所有视点的三维数据整合成连贯的完整的三维网格，并给出纹理映射方法，建立真三维、真纹理的古文物数字化模型。提出的方法已经在云冈石窟和古建数字化工程的实践中得到了充分验证。 |

| Abstract: | Digital preservation of cultural heritage sites and objects has become a global problem, A real 3D digital method for culture heritage sites and objects was proposed using 3D laser scanners and CCD cameras. Firstly, the laser scans were preprocessed for noise removal and holes filling. Next step was using an improved ICP algorithm to register multiple laser scans step-by-step, Finally, a volumetric-based algorithm was used to construct a coherent 3D mesh that enclosed all range scans, and real 3D models of cultural heritage sites and objects were created through texture mapping. The examples of constructing 3D models of buildings and grottos have been presented, and the prefect results have been obtained. |
| Keywords: | cultural building 3d digital method laser scan 3d model camera calibration texture mapping |
