摘　　要：针对倾斜摄影方法和近景摄影测量方法在水工程体三维实景重建中均存在不足的情况,提出了一种水工程体无人机贴近摄影和质量控制方法。通过带有RTK的无人机进行四点定位,从而快速确定拍摄面并进行贴近摄影;再对拍摄影像空中三角测量后的初始点云进行智能化分析,自动确定影像覆盖不足区域并进行补充摄影,以保证水工程体建模效果的精细与完整。通过清江水布垭大坝的无人机摄影与数据处理实验证明,该方法可高效快速地实现水工程的完整精细实景三维建模。In view of the shortcomings of both oblique photogrammetry method and close-up photogrammetry method in the real scene 3D reconstruction of water engineering, we proposed a UAV nap-of-the-object photogrammetry and quality control method of water engineering. Through the UAV with RTK for four-point positioning, the method can quickly determine the shooting surface and implement the nap-of-the-object photogrammetry, then intelligently analyzes the initial point cloud after aerial triangulation of the shooting images to automatically determine the insufficient area of image coverage, and implements supplementary photography, to ensure the fine and complete 3D modeling effect of water engineering. The UAV photogrammetry and data processing experiments of Qingjiang River Shuibuya Dam prove that this method can achieve the complete fine real scene 3D modeling of water engineering efficiently and quickly.
