【摘要】 针对小型水库大坝缺少准确的坐标转换参数，无人机识别的行人目标难以精确三维定位的问题，提出无人机坐标系与坝体局部坐标系的转换方法。实际工程应用结果表明，坐标转换后生成的点云与激光扫描点云基本一致，对坝顶目标的非接触测量精度优于10cm。提出方法可以从任意角度和位置准确测量小目标行人在坝体结构上的位置，为小型水库大坝无人机常规巡检和建立电子围栏等提供高效且经济的方法。更多还原

【Abstract】 In view of the lack of accurate coordinate transformation parameters for small reservoir DAMS and the difficulty of accurate three-dimensional positioning of pedestrian targets identified by UAVs, a method of transforming UAVs coordinate system to local coordinate system of dam body is proposed. Practical engineering application results demonstrate that the point cloud generated after coordinate transformation is almost identical to the laser scanning point cloud, and the non-contact measurement accuracy for dam-top targets exceeds 10cm. The proposed method can measure small pedestrian targets on the dam structure from any angle and position, providing an efficient and cost-effective approach for routine drone inspections and establishing electronic fences for small reservoir dams.更多还原
