本篇論文主要是設計出以一套光學系統和一個影像感應器來擷取二個影像產生3D立體的取像光學鏡頭。3D立體取像光學系統主要分為兩個部分:雙鏡頭和主鏡頭。雙鏡頭採用伽利略式的無焦光學系統,主鏡頭則採用雙高斯結構。3D光學系統會使左右視場影像分別成像在一個影像感應器的左右兩側。影像感應器以空間多工的方式,也就是一畫框二畫面式,使左右影像畫面成像在一個影像感應器上。主要是把影像感應器分成左右兩個畫面,可以達到同時左右影像攝影。 探討3D鏡頭的設計原理,從鏡頭間距、選定光角到3D系統設計。由影像感應器提供的規格為設計出發點,分別設計出VGA、1M和2M等級的3D鏡頭。本論文的實施例適合應用在3D相機和3D攝影機的設計上,提供一種3D鏡頭的設計方案。
The main purpose of this thesis is to achieve 3D photography by an image sensor and an optical system. Stereoscopic optical system is divided into two parts: dual lens and prime lens. The dual lens uses the afocal of Galilean optical system. The prime lens uses the structure double Gauss lens.Stereoscopic optical system let right/left view image on the right/left side image sensor. The image sensor use multi-space type. Mainly to divide the mage sensor into two capture the right and left image at the same time. From the base of the dual lens, the selected optical angle and the stereoscopic system design to disguise the principle of 3D lens design. The design condition is as follow: specification of image sensor. The design condition is as follow: specification of image sensor. This paper makes three embodiments, as VGA, 1M pixel and 2M pixel stereoscopic lenses. Embodiments of this thesis apply the design of 3D cameras and 3D camcorder. This thesis provides a kind of solution of stereoscopic lens design.
