METHOD OF GENERATING A SPATIAL AND SPECTRAL OBJECT MODEL

摘要

A method of improving a spectral reflectance profile of an object using a hyperspectral imaging device includes, among other things, obtaining a series of hyperspectral images of the object where there is relative motion between the object and the hyperspectral imaging device; determining one or more parameters of the relative motion; mapping the parameters to determine an orientation of the object in each hyperspectral image in the series; identifying two or more spatial portions of the object in each hyperspectral image in the series; assigning a spectral signature to each spatial portion; and generating a multi-dimensional spectral reflectance profile from the orientation, the spatial portions, and the spectral signatures.

1. A method of improving a spectral reflectance profile of an object using a hyperspectral imaging device, comprising:
obtaining a series of hyperspectral images of the object wherein there is relative motion between the object and the hyperspectral imaging device; determining at least one parameter of the relative motion; mapping the at least one parameter to determine an orientation of the object in each hyperspectral image in the series; identifying at least two spatial portions of the object in each hyperspectral image in the series; assigning a spectral signature to each spatial portion; and generating a multi-dimensional spectral reflectance profile from the orientation, the at least two spatial portions, and the spectral signatures.
