Method and device for processing harvested root crops

FIELD: agriculture.

SUBSTANCE: method includes the stages of optically forming hyperspectral or multispectral images of the volumetric flow of the harvested root crop to obtain a plurality of image pixels, each having a spectral profile. The image pixels are analyzed to identify discrete objects in the volumetric flow. Each identified object is classified as belonging to either acceptable root crops or unacceptable root crops, by means of generating a statistical profile associated with the object based on the spectral profile of the pixels grouped within the object. The objects classified as unacceptable are removed from the volumetric flow to provide a sorted flow of the harvested root crop.

EFFECT: processing a large volume of a root crop with the possibility of sorting foreign material from a dirt-covered root crop, with minimal damage to the crop itself.
