2025年5月中旬的无人机采集的三维点云数据

该数据集为重庆市内龙石6号排土场、巨成矿山、老林沟、广安村、东方希望砂岩矿山五个典型区域的三维点云数据，每个数据文件均包含各采样点的经度（lng）、纬度（lat）及高程（elevation）坐标信息。数据采集采用大疆御系列无人机进行正射影像拍摄，通过高精度图像拼接与坐标转换处理，并结合现场布设的RTK（实时动态载波相位差分技术）控制点，最终生成具备厘米级精度的三维空间点云，可有效支撑矿区地形建模与地表形变分析等应用。

This dataset comprises 3D point cloud data collected from five typical mining areas within Chongqing Municipality: Longshi No.6 Dump Site, Jucheng Mine, Laolingou, Guang'an Village, and Dongfanghope Sandstone Mine. Each data file contains the longitude (lng), latitude (lat), and elevation coordinate information of each sampling point. The data was acquired using DJI Mavic series unmanned aerial vehicles (UAVs) for orthophoto shooting, followed by high-precision image stitching and coordinate transformation processing, combined with on-site deployed RTK (Real-Time Kinematic) control points. Finally, 3D spatial point clouds with centimeter-level accuracy were generated, which can effectively support applications such as mine terrain modeling and surface deformation analysis.
