Abstract
To provide a hyperspectral image generation device capable of generating a model for converting an RGB image into a hyperspectral image based upon a pair of the RGB image and hyperspectral image which have positional misalignment.SOLUTION: A hyperspectral image generation device comprises: a data input part to which an RGB image obtained by capturing a predetermined scene and a hyperspectral image obtained by capturing a predetermined scene are input; an optical flow estimation part which performs optical flow estimation based upon an image related to the RGB image input to the data input part and an image related to the hyperspectral image input to the data input part; an image deformation part which performs image deformation on the image related to the RGB image input to the data input part based upon a result of the optical flow estimation by the optical flow estimation part; and a storage part which associates the RGB image input to the data input part with an image related to the image deformed by the image deformation part, to store them.SELECTED DRAWING: Figure 4
