【Abstract】 Hyperspectral images have many advantages such as multi-band, high spectral resolution, abundant information and so on. They provide convenience for people, but also bring problems like difficulty of real-time processing and huge computing and etc. Thanks to its strong computing ability, cost-effectiveness and low energy consumption, in recent years, general computation based on GPU has been sweeping across the High-performance computing field. Domestic and overseas scholars are getting down to research Parallel processing for hyperspectral images on GPU platform. This paper gave a brief introduction of Hyperspectral remote sensing and GPU application in several fields, summarized the research status of hyperspectral based on GPU recently, pointed out the existing problems, and looked into the future research prospect, to provid a reference to scientists in the field of parallel processing hyperspectral image.更多还原
