Abstract: Disclosed are a hyperspectral imaging method and an apparatus thereof. A method of reconstructing a hyperspectral image includes receiving an image photographed through a diffractive optical element and reconstructing a hyperspectral image of the received image based on the received image and information about a point spread function for each wavelength of the diffractive optical element. The diffractive optical element may generate an anisotropic shape of the point spread function that varies with a spectrum.

Abstract: Disclosed is a high-resolution three-dimensional (3D) scanning method and system that may acquire high-detail geometry by connecting a volumetric fusion and multiview shape-from-shaping (SfS) in two stages and may include estimating an illumination and acquiring a scalar depth value; estimating a photometric normal and a diffuse albedo using the scalar depth value acquired from the estimated illumination; and integrating the scalar depth value to a volumetric distance field, refining the photometric normal and the diffuse albedo, and blending the photometric normal and the diffuse albedo in a texture space.

Abstract: A method for reconstructing a hyperspectral image and a system therefor are provided. The method includes obtaining a dispersion model for dispersion created by a prism included in a camera, the prism including no coded aperture, and reconstructing a hyperspectral image corresponding to a captured image based on the dispersion model.
