Method For Taking Rolling Hyperspectral And Panchromatic Images Combined By Means Of A Spatial Imager

Abstract: The invention relates to a method for taking rolling images by means of a spatial imager comprising, in its focal plane, a pixel-array detector the pixels of which are arranged in rows and columns, said array detector being equipped with a global shutter. According to the invention, hyper-spectral images of a region of interest are captured in various spectral bands, the hyper-spectral images being obtained by acquiring successive hyper-spectral frames, by means of said array detector; panchromatic images of the region of interest are captured, the panchromatic images being obtained by acquiring successive panchromatic frames, by means of said array detector, the acquired panchromatic frames having overlaps; the hyper-spectral frames and the panchromatic frames being acquired in alternation, the hyper-spectral frames are processed to sum the successive rows of the same strip in the hyper-spectral region.
