Claims (4)
- 차량용 연료 게이지의 각도 검출 시스템에서,(a) 샘플로 선택한 연료 게이지의 지침을 그 이동영역의 최상단에서 최하단에 걸쳐 이동하는 단계,(b) 상기 샘플로 선택한 연료 게이지를 일정 주기로 카메라로 영상 캡쳐하는 단계,(c) 상기 캡쳐된 이미지를 필터링하는 단계,(d) 상기 필터링된 이미지로부터 연료 게이지의 각도를 컴퓨터로 연산하여 룩업 테이블을 작성하는 단계 및(e) 성능을 검사할 연료 게이지를 작동하고, 상기 룩업 테이블을 참조하여 연료 게이지의 각도를 검출하는 단계를 포함하는차량용 연료 게이지의 각도 검출방법.
- 제1항에서,상기 (d)단계에서 연료 게이지의 각도 연산은 연료 게이지의 눈금 중의 하나의 각도를 연산하여 기준 눈금의 보상값을 구하고 이 보상값을 실제 지침의 각도에 합산하여 연료 게이지의 각도를 구하는 각도 검출방법.
- 제1항에서,상기 (d)단계에서 룩업 테이블은 지침의 일정 각도별로, 기준 X좌표에 대한 이에 대응하는 지침의 상단선 및 하단선의 Y좌표값을 읽어들여 이들 좌표값을 테이블의 내용으로 하는 각도 검출방법.
- 제1항에서,카메라로 영상 캡쳐된 연료 게이지의 이미지를 지침의 작동범위만 나타낼 수 있는 영역만 잘라내어 새로운 이미지로 저장하고 이를 필터링용 신호 처리부로 전송하는 단계를 더 포함하는 각도 검출방법.
