乌海、灵武排土场无人机航拍数据

影像数据由无人机航拍完成。航拍无人机采用大疆 Phantom 4 Advanced，影像传感器为 1 英寸 CMOS，有效像素 2 000 万，相机焦距 9 mm，最长飞行时间约 30 min，最大可承受风速 10 m/s，可以实时显示飞行高度和 GPS 信息。本试验航拍相对地面高度为 150 m，地面分辨率可达到 0.05 m。试验于 2018 年 8 月进行，选择适合无人机飞行的晴朗无风天气获取影像，航拍时间在正午附近，以减少因阴影对影像产生的影响。

The image data was collected via unmanned aerial vehicle (UAV) aerial photography. The UAV platform used was the DJI Phantom 4 Advanced, which is equipped with a 1-inch CMOS image sensor featuring 20 million effective pixels. The camera has a focal length of 9 mm. The maximum flight endurance of the UAV is approximately 30 minutes, and it can operate in wind speeds up to 10 m/s. It also supports real-time display of flight altitude and GPS information. For this experiment, the aerial photography was conducted at a relative ground altitude of 150 m, yielding a ground sampling distance (GSD) of 0.05 m. The experiment was carried out in August 2018. Images were acquired under clear, windless weather conditions suitable for UAV flight, with the aerial photography performed around noon to minimize shadow-induced impacts on the images.
