METHOD AND DEVICE FOR DETERMINATION OF WEAR PART LOCATION ON WORKING TOOL IMAGE Russian patent published in 2020 - IPC G06T7/00 G06N3/02 G06N3/08 E21C35/00 E02F3/04 

FIELD: physics.

SUBSTANCE: group of inventions relates to image processing for determination of wear part location on working tool image. Device for location of wear part on working tool image includes image sensor for gripping at least one image of working tool during operation of heavy equipment, wherein the image comprises a plurality of pixels, each having a defined brightness value, a processing circuit configured to: select consecutive subsets of pixels from a plurality of pixels; processing each subset of pixels to determine whether pixel brightness values from a subset of pixels satisfy a matching criterion which indicates a probability that a subset of pixels corresponds to a wear part. Processing of each subset of pixels includes processing of each subset of pixels by means of the corresponding multiple input nodes of the neural network, each input unit has the weight assigned to it and is capable of creating weighted output signals in response to the received brightness value. A compliance criterion is based on processing of the marked plurality of training images during the training exercise prior to capturing at least one image of the working tool, wherein the training exercise enables to determine assigned weights for a plurality of input nodes.

EFFECT: technical result is faster installation in commissioning, high reliability of monitoring system wearing parts.
