Abstract

A device for evaluating quality of a radiographic testing image and a method therefor are proposed, and the method includes, when a wire area image is input which is an image of an area where wires of each Image Quality Indicator (IQI) exist in a radiographic image of a target object that is attached with one or more image quality indicators and radiographed through radiation, a step of preprocessing, by a preprocessing unit, the wire area image, a step of binarizing, by a binarization unit, the wire area image, a step of detecting, by a line detection unit, lines in the wire area image, a step of counting, by a counting unit, the number of wires of each image quality indicator according to the detected lines, and a step of evaluating, by an evaluation unit, a quality of the radiographic image according to the number of counted wires.
