摘要(Abstract)：

针对古村落对三维实景模型的高精度、精细化真实还原需求,该文设计了一种基于影像进行三维实景重建的技术方法。采用多旋翼无人机和手持三轴云台相机分别采集低空和地面的多视角影像,通过Context Capture软件对来自地面、低空的多视角影像分别进行空中三角测量和区块合并,实现了地面、低空多视角影像的集成,并进行三维实景建模。该方法应用于东莞市南社古村落的三维实景建模工作中,结果表明,该方法建模成果的几何精度和纹理贴图满足相关规范要求,适用于大型文化遗产的三维实景建模。该方法充分利用低空和地面不同位置的视角的优势,能够为大型文化遗产采集较为完整的影像信息,在构建高精度、还原效果好的三维实景模型方面具有明显的优势。
