METHOD AND SYSTEM FOR DETERMINING COLOUR FROM IMAGE Russian patent published in 2016 - IPC G06T11/40 G06T7/00 G01J3/46 G06K9/62 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to systems for determining the colour of a colour sample from an image of the colour sample. Disclosed is a method of determining colour from an image. The method includes a step of receiving first image data relating to an unknown colour sample, colorimetric data of which are to be determined, and receiving second image data relating to a plurality of known calibration colour samples, colorimetric data of which are already known. Further, the method includes determining a plurality of colour calibration characteristics which associate colour measurements of known calibration colour samples from the second image data with known colour data of the calibration colour samples, and calculating colorimetric data of the unknown colour sample depending on colour measurements thereof based on the first image data and colour calibration characteristics.

EFFECT: eliminating distortion of the image of known calibration colours owing to the use of aspect conversion depending on the position of identified points on the image.
