Zusammenfassung: | The present invention relates to an apparatus and a method for recognizing an absolute position by using marker recognition in a roadbed. More specifically, the present invention relates to an apparatus and a method for recognizing an absolute position by using marker recognition in a roadbed to find a precise position with respect to a captured defect section. Accordingly, information obtained from a tachometer installed in a vehicle to be detected and position information in concrete roadbed images can be recognized as absolute positions, instead of relative positions, by using the marker recognition in a roadbed and matched with concrete roadbed defect images in real time so that a defect section can be found within a short period of maintenance time.
본 발명은 도상내 마커인식을 이용한 절대 위치인식장치 및 그 방법에 관한 것으로, 촬영된 결함구간에 대해 정확한 위치를 찾기 위한 도상내 마커인식을 이용한 절대 위치인식장치 및 그 방법에 관한 것이다. 본 발명은 검측차량에 설치된 타코메타로 취득된 정보로 콘크리트 도상 영상내 위치정보를 도상 내 마커 인식으로 상대위치가 아닌 절대 위치로 인식하여 콘크리트 도상 결함 영상과 실시간으로 매칭하여 결함구간을 짧은 유지보수 시간내 찾을 수 있는 효과가 있다. |
