More Information
Summary:The present invention relates to a calibration cradle for a three-dimensional scanner. The calibration cradle includes: a cradle body in which a front-end part of the three-dimensional scanner is inserted and settled; a calibration pattern plate (abbreviated as "pattern plate" hereinafter) disposed inside the cradle body to correct scanning of the three-dimensional scanner; and a pattern moving unit allowing the pattern plate to automatically rotate and reciprocate in an axial direction inside the cradle body when the three-dimensional scanner is coupled to the cradle body. The calibration cradle provides the advantage of improving the convenience and reliability of performing calibration. 본 발명은 3차원 스캐너용 캘리브레이션 크래들에 관한 것으로서, 특히, 3차원 스캐너의 전단부가 삽입 안착되는 크래들 본체, 상기 크래들 본체의 내부에 배치되어 상기 3차원 스캐너를 스캐닝 보정하는 캘리브레이션 패턴 플레이트(이하, '패턴 플레이트'라 약칭함) 및 상기 3차원 스캐너가 상기 크래들 본체에 결합되면 자동으로 상기 패턴 플레이트를 상기 크래들 본체의 내부에서 축 회전 및 축 방향 왕복 이동시키는 패턴 무빙부를 포함함으로써, 캘리브레이션 수행의 편의성 및 신뢰성을 향상시키는 이점을 제공한다.
