Abstract:
조명광학계와결상광학계가통합된광학계및 이를포함하는 3차원영상획득장치가개시된다. 개시된광학계는 3차원영상획득장치의조명광학계와결상광학계가서로의광축이일치하도록통합되어있는구조를갖는다. 따라서, 조명광학계와결상광학계사이에시차가존재하지않기때문에, 조명광을수광하여계산한피사체에대한깊이정보는피사체와 3차원영상획득장치사이의실제의거리를반영할수 있다. 그결과, 피사체에대한깊이정보가더욱정확해질수 있다. 또한, 조명광학계와결상광학계사이에시차가존재하지않으므로, 조명광의이용효율을향상시킬수 있다. 그결과, 3차원영상획득장치에입사하는광량이증가하여피사체에대한깊이정보가더욱정확해질수 있다.
Abstract:
PURPOSE: An optical system and a three-dimensional image acquisition apparatus including the optical system are provided to accurately obtain depth information about a subject. CONSTITUTION: An imaging object lens(111) forms an opening(115) in the central part through which an optical axis passes. An illuminance object lens(122) is arranged within the opening of the imaging object lens. A light source(121) provides illuminance to the illuminance objective lens. The imaging object lens and illuminance object lens share the optical axis. The optical axis of the imaging object lens accords with the optical axis of the illuminance objective lens.
