| 中文摘要: |
| 曲面重构软件存在操作复杂、交互定义太多、对输入数据要求过于严苛等问题，至今未得到广泛推广。本文选取了徽派建筑所特有的穿斗抬梁式木构架作为研究对象，提出了一套完整的从获取点云数据，到点云预处理，最后曲面重构的实现方案。首先，对所获取的点云数据进行预处理操作，包括分割和滤波；其次，直接从点云数据集中近似推断表面法线；最后，采用泊松算法进行曲面重构研究。通过对比三维软件曲面重构最后模型，结果表明文中方案更具顺滑性、时间效率更高、良好的可移植性。 |

| Surface reconfiguration softwares have many problems such as complicated operation on point cloud data, too many interaction definitions, and too stringent requirements for inputting data. Thus they have not been widely popularized so far. This paper selects the unique Huizhou Architecture chuandou wooden beam framework as the research object, and presents a complete set of implementation in data acquisition from point cloud preprocessing and finally implemented surface reconstruction. Firstly, preprocessing the acquired point cloud data, including segmentation and filtering.Secondly, the surface’s normals are deduced directly from the point cloud dataset. Finally,the surface reconstruction is studied by using Possion Algorithm. After comparing the reconstructed model with the three-dimensional surface reconstruction softwares, we may find that the proposed scheme is more smooth, time efficient and portability. |
