(KO) 스테레오 매칭 장치 및 방법
Abrégé :
(EN) The present invention relates to a stereo matching apparatus and method and particularly provides a stereo matching apparatus comprising: an image input unit for receiving the input of a left-eye image and a right-eye image; a census transform setting unit for setting a matching window size, the number of sample points, and an edge distance; a census transform unit for generating census transform bit strings by comparing the pixel brightness values of respective sample points, sampled as many as the number of the sample points, with those of other sample points, being as far away as the edge distance and symmetrically positioned, within a matching window by using the set matching window size, number of the sample points, and edge distance; and a stereo matching unit for performing stereo matching by using the census transform bit strings. The present invention is faster and more accurate than conventional census transform apparatuses and is robust in terms of image noise, rotation changes, and the like.
(FR) L'invention concerne un appareil et un procédé d'adaptation stéréo, et plus particulièrement, un appareil et un procédé d'adaptation stéréo faisant appel à une transformation de census améliorée (CT).
(KO) 본 발명은 스테레오 매칭 장치 및 방법에 관한 것으로서, 구체적으로는 좌안 영상 및 우안 영상을 입력 받는 영상 입력부; 매칭 윈도우 크기, 샘플 점 개수 및 에지 거리를 설정하는 센서스 변환 설정부; 설정한 매칭 윈도우 크기, 샘플 점 개수 및 에지 거리를 이용하여, 매칭 윈도우 내에서 샘플 점 개수만큼 샘플링한 각각의 샘플 점을 에지 거리만큼 떨어져 대칭적으로 위치한 다른 샘플 점과 화소 밝기 값을 비교하여 센서스 변환 비트 열을 생성하는 센서스 변환부; 및 센서스 변환 비트 열을 이용하여 스테레오 매칭을 수행하는 스테레오 매칭부를 포함하는 스테레오 매칭 장치를 제시하고 있다. 본 발명은 종래의 센서스 변환 장치에 비하여 보다 빠르고 정확하며 영상의 잡음과 회전 변화 등에 강건한 효과가 있다.
