Title:
MATERIAL IDENTIFICATION ASSISTANCE DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/180776
Kind Code:
A1
Abstract:
The present invention addresses the problem of selecting a measurement condition at an accuracy matching the material identification performance of a material DB without referencing a material DB about a feature amount. To address the above problem, the present invention is provided with: a spectral analysis unit 3 for receiving a plurality of items of spectrum data acquired by a measurement device 2 with regards to a material according to a prescribed measurement condition, and calculating spectral feature amounts of the spectrum data using a model function; a standard deviation acquisition unit 4 for estimating, on the basis of the spectral feature amounts, the standard deviation between the model function and the values actually measured by the measurement device; and a feature amount error-identification accuracy degree relationship analysis unit 6 for calculating, for each of the spectral feature amounts, an identification accuracy degree in relation to identifying the material, using spectral feature amount-material identifier correlation information indicating the correspondence relationship for the material identifier in question, and generating, using the identification accuracy degree and the standard deviation, feature amount error-identification accuracy degree correlation information indicating the correlation relationship between the identification accuracy degree and the spectral feature amount error for the material.
