Quick spectrum video reconstruction method based on aliasing sampling of GPU

The invention discloses a quick spectrum video reconstruction method based on aliasing sampling of a GPU. The quick spectrum video reconstruction method mainly settles a problem of low speed in a spectrum video reconstruction technique in existing aliasing code sampling. The technical solution of the quick spectrum video reconstruction method is characterized in that a system according to the quick spectrum video reconstruction method comprises a spectrum video observation part and a spectrum video inversion part; wherein the spectrum video observation part finishes an observation process of the spectrum data and obtains spectrum observation video; the spectrum video inversion part obtains the spectrum video from the spectrum observation video through inversion according to a parallel algorithm, thereby obtaining three kinds of selective spectrum data, wherein the frame rate of the spectrum data is 30 frames per second and the spatial resolutions of the spectrum data are respectively 300*300, 600*600 and 1200*1200. The quick spectrum video reconstruction method greatly improves a reconstruction speed and furthermore can satisfy a requirement for different reconstruction time, thereby expanding an application range. The quick spectrum video reconstruction method can be used for spectrum video acquisition in resource exploration, geological hazard detection and medical diagnosis.
