立體顯示技術(Three-dimensional Display Technologies)是目前顯示器科技產業的主流技術之一，可呈現具有深度空間感(Depth Perception)及立體視覺的影像。然而目前市面上常見應用於平面顯示器的立體視覺影像大部分是電腦軟體虛擬的場景，極少是真實場景擷取的實物影像，欠缺真實感及實用性。
本論文提出自動化實物擷取(Real Object Image Capture)技術，以針孔陣列(Pinhole Array, PA)實現堆疊成像(Integral Imaging)立體顯示技術為理論基礎，於iPad 2智慧型裝置顯示器同時呈現水平與垂直視差的立體視覺影像。實物擷取影像技術是利用自動化系統控制物體旋轉改變視差角度，由一台相機拍攝旋轉前後之視差圖像，產生立體像對(Stereopair)。視差圖像經處理後，貼合PA薄膜片即呈現立體視覺影像。本研究提出一種新的製圖方式，改善視差圖像重疊時造成的串擾(Crosstalk)。
本論文所獲得之研究成果有助於未來想要製作實物立體視覺影像者，以標準作業程式製作一個高品質立體視覺影像。

Three-dimensional (3D) display technologies have recently become mainstream in the imaging display industry. As of now, most 3D images are derived from illustrations composed using computer software, and not from real-life images. This inadvertently gives a diminished touch of realism.
This current study proposed an real object 3D images capture technique. An automatic control system was used to rotate the sample real object, alter the parallax angle, and control the camera to capture the parallax images. We have also proposed a new permutations method to improve the crosstalk caused by overlapping the parallax images. Based on Integral Imaging (II) using Pinhole Array (PA), 3D images were created. The display device used in this study is an Apple iPad 2. Taking into account the depth resolution of the image, it was viewed with both horizontal and vertical motion parallaxes in mind.
The findings obtained from this study are potentially of use for parties interested in utilising real-life photographs to create high-quality 3D images.
