METHOD OF DETERMINING ICE RIDGES ON ICE COVER ON WATER AREAS Russian patent published in 2013 - IPC G06T7/40 G06K9/70 G01C11/04

Abstract RU 2500031 C1

FIELD: physics.

SUBSTANCE: in the method, by selecting on an original infrared image reference points representing values of ice thickness and brightness thereof; using values of brightness and the calculated functional relationship between a virtual relief and the relief of the brightness field on the infrared image obtained from an artificial earth satellite; for the original infrared image, brightness of "warm" and "cold" points is calculated; the analysed image is displayed in form of a spatial distribution of matrix elements corresponding to brightness values of each image pixel; ordered structures of the brightness field are selected and then displayed in form of a colour painting.

EFFECT: enabling monitoring of the state of ice cover on water areas by determining thickness of the ice cover, averaged on a local resolution element.
