FIELD: measurement equipment.
SUBSTANCE: method involves analysis of an image of mixture surface and determination of coefficient of its non-homogeneity. The investigated mixture is uniformly distributed on a smooth surface and divided into necessary number of portions; digital images of their surfaces with build-up of brightness histograms are obtained. Then, each portion is divided into equal number of parts (probes) with build-up of their brightness histograms. Mixture non-homogeneity coefficient is calculated by comparing digital images of parts (probes) of a piston with an image of the whole portion of the investigated mixture as per brightness histograms.
EFFECT: reducing labour intensity, increasing speed and accuracy of determination of quality of mixture of components that differ as to colour.
