Abstract
본 발명은 VCR헤드의 영상 처리를 통해 VCR헤드의 자동 조정 시스템의 기구적 오차를 정확하게 측정하고 보정하는 VCR헤드의 자동조정 방법에 관한 것으로서, 드럼의 장착 오차를 장착 오차 측정부를 통해 측정하는 단계와, 상기 드럼의 장착 오차를 보상하도록 180˚기준선의 좌표를 계산하는 단계와, 각 헤드를 영상 처리하여 헤드 기준점의 좌표를 측정하는 단계와, 보정 파일을 생성하는 단계로 이루어져, VCR헤드의 자동 조정 시스템의 기구적인 오차를 자체적으로 자동으로 조정하여 180° 및 단차 조정이 정확하고 용이하게 조정되는 효과가 있다.The present invention relates to an automatic adjustment method of a VCR head for precisely measuring and correcting a mechanical error of an automatic adjustment system of a VCR head through image processing of a VCR head, comprising the steps of measuring a mounting error of a drum through a mounting error measuring unit Calculating the coordinates of the 180 degree reference line to compensate for the mounting error of the drum, measuring the coordinates of the head reference point by image processing each head, and generating a correction file, The systematic error of the system is automatically adjusted by itself, and the 180 ° and step adjustment can be adjusted accurately and easily.
