资源简介

摘要: 针对古建筑三维重建中传统技术很难同时兼顾高精度三维信息快速获取和多角度真实地物纹理特征准确采集的难题,提出联合三维激光扫描与倾斜摄影测量技术的古建筑三维重建新方法。新方法充分结合了两种技术的优势,利用特征点匹配算法来实现多源数据精确融合,从而实现古建筑室内外完整三维模型的构建。以中国传统村落渐山村李氏家庙为例,通过该方法构建的三维模型与实际激光测距仪测量数据比较,其相对中误差为5 mm, 且建模效率相对于传统方法也有大幅提升;此外,将构建的模型以不同比例尺进行3D打印与室内外展示,进一步验证了建模数据的可用性;表明该方法将为古建筑文化遗产的修复与保护提供重要技术支持。 关键词: 三维激光扫描;  无人机倾斜摄影;  数据融合;  古建筑重建;  3D打印     Abstract: Modeling ancient architectures by traditional methods can hardly obtain high precision 3D spatial information and the texture information of the target object at the same time. This study proposes to combine the 3D laser scanning technology and tilt photography measurement technology to quickly restore the 3D information of ancient architectures. This method fuses multi-source data by feature matching and establishes the complete 3D model of the ancient architecture (inside and outside). The validation using the Li's family temple in a traditional Chinese village in Fujian province, China, shows that the relative mean error of the established 3D model is 5 mm. Furthermore, this method increases the modeling efficiency greatly. In addition, the constructed model is used for 3D printing and indoor and outdoor display in different scales, and the availability of model is further verified. This research will provide technical support for the restoration and protection of ancient architectures.
