Abstract:
1. An apparatus for recognizing an object using a multi-wavelength spectrometer, the apparatus comprising: a processor, a storage medium containing program instructions, execution of which by the processor causes the apparatus to provide functions of: a light irradiator configured to irradiate light of a plurality of wavelengths to the object corresponding to the detected region of interest; and a light receiving unit receiver configured to measure a spectrophotometric value for each light of the plurality of wavelengths; wherein the light processing unit is configured to generate a differential spectrophotometric map using differential spectrophotometric values between the spectrophotometric values of different wavelengths measured at a same light irradiation position, and recognize the object using the differential spectrophotometric map and the shape information.
