Abstract
A snapshot hyperspectral imaging method includes the steps of: S, selecting a set of reference wavelengths for calibration, rectifying the shifted positions due to dispersion at each reference wavelength, and selecting a center wavelength; S, estimating relative dispersion at each reconstructed wavelength with respect to the center wavelength; S, generating a dispersion matrix describing the direction of dispersion, and generating a spectral response matrix using a spectral response curve of a sensor; S, capturing images blurred with dispersion; S, deblurring the dispersed images captured in Susing the dispersion matrix and the spectral response matrix generated in Sto obtain spectral data spatially aligned in all spectrums; and S, projecting the aligned spectral data obtained in Sinto color space, extracting a foreground image by a threshold method, sampling the dispersed images obtained in Sas strong prior constraints for the foreground image, and reconstructing accurate spatial hyperspectral data.
