TJ_CS_Hyperspectral

We employed Hexacopter unmanned aerial vehicle (UAV) equipped with the SPECIM FX17E hyperspectral camera to implement ultra-low-altitude flight aerial photography missions with atmospheric correction processing. We collected three hyperspectral images and combined them into three data pairs, which exhibit varying degrees of spectral shift. Among them, a hyperspectral image including six types of ground objects was collected in Changsha at 4:00 pm on September 27, 2021, with sunny weather and a flight altitude of 30m, named CSSunny. Besides, we captured two hyperspectral images in Tianjin, both of them contain twelve types of ground objects and the flight altitude was 60m. One of them was shot at 3:00 pm on March 21, 2023, with sunny weather, and the other was shot at 3:30 pm on March 22, 2023, with cloudy weather, named TJSunny and TJCloudy respectively. The spatial resolution of three images in the self-collected data pairs is 482 × 640, and the spectral wavelength of them ranges from 935nm to 1720nm with 224 bands.

本研究采用配备SPECIM FX17E高光谱相机的六旋翼无人机（UAV）执行了超低空飞行航空摄影任务，并进行了大气校正处理。我们收集了三幅高光谱图像，并将它们组合成三组数据对，这些数据对呈现出不同程度的谱线偏移。其中，一幅包含六种地面物体的高光谱图像于2021年9月27日下午4点在长沙采集，当天气候晴朗，飞行高度为30米，命名为CSSunny。此外，在天津我们还采集了两幅高光谱图像，均包含十二种地面物体，飞行高度为60米。其中一幅于2023年3月21日下午3点拍摄，当天气候晴朗，另一幅于3月22日下午3点30分拍摄，当天气候多云，分别命名为TJSunny和TJCloudy。所收集数据对的三幅图像的空间分辨率为482×640，光谱波长范围在935nm至1720nm之间，包含224个波段。
