Abstract
Description
Claims (3)
- 자동차 실내의 영상을 촬영하여 전기적인 신호를 출력하는 촬영수단과; 승객이 탑승하지 않은 자동차 실내의 영상과, 사람의 참조 영상의 데이터를 저장하고 있다가 외부로부터의 요구에 따라 해당하는 데이터를 출력하는 영상 저장 수단과; 상기 촬영수단으로부터 출력되는 신호를 입력받아 상기 영상 저장수단에 저장되어 있는 데이터를 이용하여 자동차 실내의 승차자의 유무 및 위치를 판단하여 그에 따른 신호를 출력하는 제어수단으로 이루어져 있는 것을 특징으로 하는 승객 유무 판단 장치.
- 청구항 1에 있어서, 상기 촬영수단은 씨씨디 카메라로 이루어져 있는 것을 특징으로 하는 승객 유무 판단 장치.
- 촬영된 영상을 판독하여 미리 설정되어 있는 승차자가 없을 때의 영상과 비교하여 자동차 실내 구조 부분을 삭제하는 단계와; 노이즈 성분과 사람이라고 생각되기에 너무 작은 부분을 제거하는 단계와; 미리 설정되어 있는 사람의 참조 영상과 비교하여 사람으로 추정할 수 있는 부분을 찾는 단계와; 상기 단계에서 사람으로 추정할 수 있는 부분을 승차자의 위치로 판정하고 영상에서 삭제하는 단계와; 삭제후 남은 영상이 존재하는지 판단하여 남은 부분이 있으면 상기 참조 영상과 비교하는 단계로 분기하는 단계와; 상기에서 삭제후 남은 영상이 존재하지 않는 경우, 판정된 위치에 승차자가 존재함을 신호로 출력하는 단계로 이루어져 있는 것을 특징으로 하는 승객 유무 판단 방법.
