METHOD OF INCREASING ACCURACY AND INFORMATION CONTENT OF NONDESTRUCTIVE INSPECTION RESULTS Russian patent published in 2011 - IPC G01N25/72 

FIELD: physics.

SUBSTANCE: in order to increase accuracy and information content of nondestructive inspection results, defect characteristics are determined by comparing experimental values of temperature fields recorded during defectoscopy of the inspected object with values of coordinates of (characteristics) of temperature fields entered by experts before inspection into the "knowledge base", which correspond to different combinations of defect characteristics using a "disparity" method, where before defectoscopy of the inspected object, inspection error is measured based on measuring defect characteristics (1^st operation), obtained by different inspectors; statistical characteristics of error values of results are measured; one of three or four best experts (inspectors) are determined (e.g. using Fisher's ratio test) for populating the "knowledge base" by evaluating quality of their work according to a defined mathematical expression and inequality.

EFFECT: increased reliability and information content of flaw detection results.
