The research on wide-field hyperspectral imaging technology with UAV

A technology of wide-field hyperspectral with unmanned aerial vehicle (UAV) was introduced,a frame hyperspectral camera,whose spectrophotometer was based on the mosaic filter,was used to scan in the direction of the wingspan to achieve wide-field and high spectral resolution image.An outfield flight test has done,which obtained wide-field and high spectral resolution observation image over the ground with high quality.The flight operation efficiency is 8.64 km2/h,which is about 3.4 times higher than the single camera imaging without scanning.With simple structure,obvious advantages in size and weight,the camera has a broad prospect in unmanned aerial vehicle hyperspectral remote sensing.The results of research in this paper have a certain reference value in promoting unmanned aerial vehicle load imaging spectrometry to develop in the direction of wide field and high spectral resolution.
