Title:
APPARATUS AND METHOD FOR ACQUIRING SURFACE MULTI-POINT CHROMATICITY COORDINATE VALUES OF PHOTOGRAPHED OBJECT
Document Type and Number:
WIPO Patent Application WO/2024/073869
Kind Code:
A1
Abstract:
The present application mainly relates to the fields of color vision, colorimetry, color communication, image processing, computer control, deep learning, applied mathematics, etc. Provided are an apparatus and method for acquiring surface multi-point chromaticity coordinate values of a photographed object. By means of the apparatus and method for acquiring an image of a photographed object together with a color block group under irradiation of light sources in different spectral distribution and then calculating surface multi-point chromaticity coordinate values of the photographed object, the problems of the existing means for carrying out measurement of surface multi-point chromaticity coordinate values of an photographed object being difficult and inaccurate and having a high cost are solved.
