COMMODITY DISCRIMINATING DEVICE, COMMODITY DISCRIMINATING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a commodity discriminating device suitable for discriminating a commodity such as food or the like, a commodity discriminating method and a program.;SOLUTION: A wave number absorbance-by-commodity housing part 101 houses a plurality of spectral analyzing result containing a wave number value, which is determined by the spectral analysis of an inspection target and the absorbance value in the wave number value. A correlation ratio is calculated on the basis of the spectral analyzing result by a correlation ratio calculation control part 110 and a wave number value sufficiently large in correlation ratio is sorted in an explanation variable sorting part 106 and a sorting result is stored in a explanation variable candidate housing part 107. A canonical form discriminating and analyzing formula forming part 108 forms a discriminating and analyzing formula capable of discriminating a commodity by spectral analysis on the basis of the spectral analyzing result and the sorting result of the wave number value to be stored in a canonical form discriminating and analyzing formula housing part 109.;COPYRIGHT: (C)2007,JPO&INPIT
