Hyperspectral imaging device data noise elimination method

Noise removing method hyperspectral imager data (1) to obtain the surface reflectance data to remove noise atmospheric effects; (2) selecting a relatively stable, homogeneous characteristic feature region, the region feature quantity Statistics surface reflectance data ; (3) the band dividing hyperspectral imager data is the data smoother band and data distortion associated band, data distortion is irrelevant band; (4), respectively, the data information distortion associated band, data distortion is not related to the band noise removal; (5) the data band and more stable after the above-described noise removal band data information related to the distortion, the distortion is not related to the band data, using the measured surface reflectance, the reflectance of the reflection optimal conversion level field experience, to eliminate the accumulated error hyperspectral imager noise data processing, the finally obtained surface reflectance hyperspectral imager data to remove noise.
