Abstract

본 발명은 라인스캐닝을 이용한 이미지의 프린지추출방법에 관한 것으로, 화상의 잡음성분제거 및 화상의 에지를 강조하기 위한 전처리단계, 이 전처리된 화상을 라인단위로 스캐닝하는 단계, 스캐닝된 라인단위의 화상데이터를 주위환경을 참조로하여 소정라인분의 화상데이터를 평활화하는단계, 평활화된 화상데이터로부터 최소값을 산출하여 프린지위치를 추적하기 위한 피크점을 추출하는 단계, 이 피크점을 기초로 화상의 프린지를 추출하는 단계로 구성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fringe extraction of an image using line scanning, comprising: a preprocessing step for removing noise components of an image and emphasizing an edge of the image, scanning the preprocessed image line by line, and image scanned line unit Smoothing image data of a predetermined line with reference to the surrounding environment; extracting a peak point for tracking the fringe position by calculating a minimum value from the smoothed image data; and fringe of the image based on the peak point. It consists of extracting.
