Abstract
A system for generating hyperspectral imaging data for measuring biochemical compositions is disclosed which includes a spectral imaging device adapted to acquire one or more hyperspectral linescan images, an optical imaging device with a red-green-blue (RGB) sensor adapted to acquire an RGB dataset, a processor adapted to co-locate a plurality of pixels in the RGB dataset vs. a corresponding plurality of pixels of the one or more hyperspectral linescan datasets, establish a transformation matrix utilizing the plurality of co-located pixels, apply the transformation matrix to the RGB dataset to thereby generate the hyperspectral dataset, and analyze the generated hyperspectral image dataset to determine the biochemical compositions.
