隨著3D影視娛樂的蓬勃發展，裸眼立體設備的技術提供了革新的視覺感受，觀賞者不需要配戴立體眼鏡即可以裸眼視覺來欣賞立體影像。由於裸眼立體設備價格並不親民，如何透過傳統的二維顯示設備感受立體視覺成為重要的研究。視差光柵被視為是主流的解決方案，因為它在取得方面極為便利。但到目前為止，大部分的研究論文所提出的裸眼立體系統是以傳統平面螢幕為基礎，而較少考慮到投影系統。本論文旨在提出ㄧ基於視差光柵可應用於投影設備之立體系統，透過投影校正，以及基於深度繪圖演算法之立體影像產生程序，亮度補償機制，可將單視角單深度內容繪製為一保有完整多視角資訊之多視角立體影像，使觀賞者無須配帶立體眼鏡便可透過投影系統感受立體視覺。此系統可依據多樣性視差光柵調整內容，並可適用於傳統平面螢幕播放。

With the rapid development of 3D entertainment, naked-eye stereo displays provide a renovation of vision experiences; audiences can enjoy the stereo images without stereo glasses. As naked-eye stereo displays are expensive, how to perceive stereo perception with traditional display devices is a major topic. Parallax barrier is considered a solution because it is convenient for obtaining. So far, most researches are utilizing flat panel displays for autostereoscopic systems, but only a few are focus on projection devices. The goal of this thesis targets on an autostereoscopic system based on parallax barrier for projection devices, with the proposed projector calibration, the 3D content generation based on depth-image-based rendering (DIBR) algorithm, and the brightness compensation. Stereo images with intact multi-view information could be rendering form a pair of color and depth images to make audiences receive stereo effect without stereo glasses. The system can deal with versatile parallax barriers and be suitable for flat panel displays.
