Patent ID: 7554586

Claim:
A method for multi-spectral image capture of a first scene, the method comprising: acquiring a first series of images of the first scene with one or more image acquisition systems, each of the image acquisition systems having an imaging sensor which has a set of color filters thereon and has two or more color channels, each of the channels having a different spectral sensitivity; filtering each of the first series of images of the scene with a different filter from a set of non-interference, color filters, each of the non-interference filters in the set of the non-interference filters having a different spectral transmittance and is positioned between the scene and the one or more image acquisition systems; acquiring a second series of images of a second scene with the one or more image acquisition systems; and filtering each of the second series of images of the second scene with a different filter from the set of filters; generating a characteristic mapping from two or more color channel signals from the second series of filtered images; and generating a multi-spectral scene description from two or more of the acquired first series of filtered images.
