Having the advantage of acquiring spatial information and more spectral information, Hyperspectral imager is widely applied in the fields of earth-observation, precision agriculture, etc. In order to improve the quantitative ability of hyperspectral imagery, accurate radiometric and spectral calibrations are necessary. Shifts in channel center wavelengths and changes in spectral resolution may occur...
As to improve the environmental adaptability of laser probe, filter is installed on the probe. But the measurement accuracy will be depressed by the distortion of image brought by the filter. In this paper, the effect of filter to imaging feature is discussed in detail firstly. Then the distortion model is established through theoretical and experimental analysis. Finally, the distortion model is...
