High-speed rail pier construction progress detection method based on unmanned aerial vehicle point cloud

According to the high-speed rail bridge pier construction progress detection method based on the unmanned aerial vehicle point cloud, high-speed rail line construction state data obtained through aerial photography of the unmanned aerial vehicle are processed completely automatically, and judgment of three states (uncompleted, completed but not disassembled and completely completed) of a bridge pier is completed based on the three-dimensional point cloud obtained by the unmanned aerial vehicle; manual data processing is not needed any more, the construction efficiency is effectively improved, the personnel and capital cost is reduced, and powerful support is provided for fine management of a construction site. 本发明的目的在于提供一种基于无人机点云的高铁桥墩施工进度检测方法，无人机航拍获取的高铁线路施工状态数据完全自动化处理，基于无人机获取的三维点云完成对桥墩的三种状态（未完成、完成但未拆模具、完全完成）的判定，不再需要人工处理数据，有效提升施工效率，降低人员与资金成本，为实现施工现场精细化管理提供有力支撑。
