摘要
针对河湖环境布设控制点困难问题,探索了一种基于无人机免像控技术的河湖遥感监测方法。根据测区范围、地面分辨率设置飞行计划,无人机按飞行计划自动采集测区影像及POS数据;利用Agisoft Photo Scan软件一键式自动生产测区DOM和DEM。以某山区水库为试验区,布设空间分布均匀的8个检测点,通过检测点的实测坐标与解算坐标的精度分析,验证了该方法的可行性。
The method for river and lake monitoring based on UAV image free control technique is proposed to solve the difficult problem of setting up control points in rivers and lakes. According to the scope of the surveying area,the ground resolution set flight plan,UAV by flight plan automatically collects the survey area image and POS data. Using Agisoft Photo Scan software one-click automatically producing area DOM and DEM. Based on the comparison and analysis of the measured coordinates and the coordinates of the test points,the feasibility of the method is verified by a mountain area reservoir as the experimental area.
