Abstract

본 발명은 스페클 방식을 이용한 비파괴 검사 시스템에서 안정된 이진화 이미지를 획득하기 위한 이미지 프로세싱 방법에 관한 것으로, 종래에는 이미지 프로세싱에서 세선(細線)화 작업에 들어가기 전에 물체 이미지와 프린지 패턴 이미지 사이에 스페클잡음으로 인해 안정된 이진화 이미지를 획득할 수 없는 문제점이 있었다.The present invention relates to an image processing method for obtaining a stable binarized image in a non-destructive inspection system using a speckle method, conventionally speckle between the object image and the fringe pattern image before entering the thinning operation in image processing There was a problem that a stable binary image cannot be obtained due to noise.

이와같은 종래의 결함을 감안하여 본 발명은 안정된 이진화 이미지를 얻기위해 강한 로우패스 필터링 및 볼러링 작업을 여러번 거친 후 잡음성분을 제거하기 위해 라인별로 프로세싱하여 피크 및 밸리점과 센터 포인트점들을 찾아내어 프린지 패턴을 세선화 작업에 들어가기 전에 프린지 패턴을 추적한 안정된 이진화 이미지를 획득할 수 있도록 한 효과가 있다.In view of such a conventional defect, the present invention performs strong low pass filtering and bowling operations several times to obtain a stable binarization image, and then processes line by line to remove noise components and finds peak and valley points and center point points. The fringe pattern has the effect of obtaining a stable binary image that tracks the fringe pattern before entering the thinning operation.
