| 摘 要： | 针对复杂体育场馆外部精细建模在完整性和精度方面存在的问题，本文提出了地面控制、地面激光扫描、无人机建模控制一体化的高精度建模方法。首先应用特制标志建立区域内控制、扫描、无人机高精度一体化坐标系统；其次对地面多站激光扫描点云结合控制坐标进行区域整体平差配准，生成一体化坐标系统下高精度地面点云模型；然后应用无人机数据和控制点生成一体化坐标下的高精度顶部数据；最后融合两种数据生成对象完整高精度精细模型。试验证明，整体平差解算方法可实现多站点云的高精度配准，一体化控制可实现非同源异质数据高精度融合，解决了复杂建筑对象的高精度建模问题，具有很大的实用价值。

| Abstract: | In view of the problems in the integrity and accuracy of the external fine modeling of complex stadium, this paper proposes a high-precision modeling method which integrates ground control, ground laser scanning and UAV modeling control. Firstly, a high-precision integrated coordinate system of control, scanning and UAV in the area is established by using special signs. Secondly, the whole adjustment and registration of the area is carried out by combining the control coordinates of the multi station laser scanning point cloud on the ground to generate the high-precision ground point cloud model under the integrated coordinate system. Thirdly, the high-precision top data under the integrated coordinate system is generated by using the UAV data and control points. Finally, fusion of two kinds of data to generate a complete, high-precision and fine model of the object. The experiment shows that the whole adjustment method can achieve high-precision registration of multi-site cloud, and the integrated control can achieve high-precision fusion of heterogeneous data, which solves the problem of high-precision modeling of complex building objects, and has great practical value. |
