Description

추미식 차간거리측정장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본원 발명의 실시예에 의한 거리측정장치의 구성도,
제2도는 윈도우내의 화상을 비교하는 설명도,
제3A도, 제3B도는 각각 제1 및 제2의 실시예의 시각이 t=t0와 다음 시각 t=t1과의 화상을 비교하여 새로운 윈도우를 설정해서 좌우의 화상을 비교하는 설명도.

Claims (2)

  1. 좌우 1쌍의 광학계에 의해 이미지센서 위에 결상된 좌우의 화상신호를 비교하고, 화상의 광축으로부터 어긋남을 전기적으로 검출하여 비교하고, 전기적으로 검출하여 3각측량의 원리로 거리를 측정하는 거리측정장치에 있어서, 상기 좌우 어느 한쪽의 화상신호의 특정부분에 윈도우를 설정하는 수단과, 설정된 윈도우내의화상신호를 기준으로해서 좌우의 화상신호를 비교하여 거리를 구하는 수단고, 소정의 사간간격으로 화상신호를 샘플링하고, 어떤 시각의 윈도우내의 화상신호와 다음의 화상신호를 비료하여 그 신호가 가장 잘 일치되는부분을 새로운 윈도우로서 기준화상신호를 설정하고, 그 변화량으로부터 대상물의 이동방향과 이동량을 구하는 수단을 구비한 것을 특징으로 하는 추미식 차간거리측정장치.
  2. 좌우 1쌍의 광학계에 의해 이미지센서위에 결상된 좌우의 화상신호를 비교하고, 양 화상의 광축으로부터의 어긋남을 전기적으로 검출하여3각 측량의 원리로 거리를 측정하는 거리측정장치에 있어서, 상기 좌우 어느 한쪽의 화상신호의 특정부분에 윈도우를 설정하는 수단고, 소정의 산간간격으로 화상신호를 샘플링하고, 어떤 시각의 윈도우내의 화상신호와 다음의 사각의 화상신호의 차속에 대응해서 한정된 부분과 비교하여 그 신호가 가장 잘 일치되는 부분을 새로운 윈도우로서 설정하고 , 그 변화량으로부터 대상물의 이동방향과 이동량을 구하는 동시에, 앞의 시각에서 구한 거리 데이터를 기초로 해서 윈도우내 기준화상신호와 다른쪽의 화상신호의 비교에 있어서 비교영역을 차속에 따라 한정하는 수단을 구비하는 것을 특징으로 하는 추미식 차간거리 측정장치.
