METHOD AND DEVICE FOR MEASURING OBJECT COLOUR Russian patent published in 2017 - IPC G01J3/50 

FIELD: measuring equipment.

SUBSTANCE: method is realized by means of the device, that includes the facility to emit the coloured lights in the form of the light fluxes and the colour images electronic sensor. When measuring, the object under investigation is illuminated by the optional external constant ambient light flux and by the sequence of colour lights. The light flux reflected from the object is received with the help of the image sensor. The system of equations is obtained on the basis of the obtained data, that connects the reflected light flux, the external constant ambient light flux, the light flux from the illuminators and the diffuse reflecting power. On the basis of the equations obtained, the diffuse reflecting power of the investigated object and the parameters of the external constant ambient light flux are determined.

EFFECT: improvement of the accuracy and simplification of the measurement method.
