Abstract
Provided are an apparatus and method for recognizing an object on the basis of property information on an object obtained using a multi-wavelength spectrometer. An apparatus for recognizing an object using a multi-wavelength spectrometer includes an image processing unit configured to extract an region of interest from an input three-dimensional image and output shape information on the region of interest, a light irradiation unit configured to irradiate light of a plurality of wavelengths to an arbitrary position of an object corresponding to the detected region of interest, a light receiving unit configured to measure a spectrophotometric value for each light of the plurality of wavelengths, and a light processing unit configured to generate a differential spectrophotometric map using a differential value between spectrophotometric values of different wavelengths measured at the same light irradiation position, and recognize the object using the differential spectrophotometric map and the shape information.
