基于三维激光扫描的石佛院造像数字化测绘

详细探讨了多测量手段集成的吴山石佛院造像数字化测绘项目的具体作业流程和关键技术,建立了石佛院精细、准确的数字化档案。针对石佛院造像表面特征复杂、数据海量、跨度大、测站多等特点,提出基于闭合导线整体平差分配模型的三维激光扫描数据配准方法,通过序列拼接、坐标转换、整体匹配和数据统一化来实现大场景、多视点和三维点云的全局配准。

Digital Surveying and Mapping of the Statues at Stone Buddha Temple Based on 3D Laser Scanning

The specific processes and key technologies of the digital surveying and mapping of the Statues at the Stone Buddha Temple integrated multi-measurement means are discussed in detail. And the exquisite and accurate digital archives of the stone Buddha Temple are established in this paper. With regard to the features of the Statues of complex surface, massive data, large span and multi-station, a point cloud registration method for three-dimensional laser scanning data based on the distribution model of closed traverse integral adjustment is proposed. The method adopts means of sequence integration, coordinate transformation, overall matching and data unification to achieve the global registration of big scene, multi-view, three-dimensional point cloud data.
