采用激光扫描的古田会议会址三维几何造型建模

3D Geometric Modeling of Gutian Meeting Site Using Laser Scanning

将三维扫描的建模方式与传统的几何造型的建模方式相结合,提出基于激光扫描的三维几何造型建模方案.重点解决地面激光扫描仪(TLS)获取三维点云时站点布设与数据处理、几何造型中点、线、面、体的提取与三维建模,以及纹理数据处理等问题,实现目标建筑的真实感三维建模.以福建省上杭县古田会议会址为例,建立精细的三维模型.结果表明:该方案能够实现典型中式建筑风格的文化遗址数字化建模.

Combined 3D scanning modeling method with the traditional geometric modeling method, we pro-posed a geometric modeling scheme based on 3D laser scanning. It solved the sites layout problem when terres-trial laser scanner obtained 3D point cloud, the data processing, the extraction for point, line,surface and body in geometric modeling, and the problem in texture data processing and so on, which realized 3D modeling for the target building. Taking Gutian Meeting Site in Shanghang County, Fujian Province as an example, we established a 3D highly precise model. The result showed that the modeling scheme could enabled the digital modeling for the cultural heritage with typical Chinese architectural features.
