From: SpectraTrack: megapixel, hundred-fps, and thousand-channel hyperspectral imaging
A The imaging result of the line-scan imaging spectrometer installed on the drone with a gimbal. A gust up to level 5 causes shaking and leads to artifacts in the HSI image. B The reported system, comprising a side-by-side placed line-scan image spectrometer and an RGB camera was mounted under the drone. C The shaking-affected HSI images and reconstructions in the cases of shaking in flight and hovering. Our system can reconstruct clear, high-resolution HSI videos and differentiate between the subtle spectra of objects that share similar colors.
