摘要


由於近年來科技的快速發展及顯示技術上的長足進步,使得三維立體顯示再度掀起風潮,相關產業也紛紛推出新穎的三維立體顯示器。但由於製作三維立體影像的技術困難,造成缺乏內容物播放的窘境。現階段是將現有的二維影像,加入相對應的深度資訊,再藉由DIBR(Depth-image-based rendering)的技術顯示在三維立體顯示器上。當面對轉換大量二維平面影像至三維立體影像時,採用自動轉換系統,不需花費大量的人工手繪時間,進而提高消費者使用的意願,以達到拓展三維立體顯示的市場。 本論文著重於自動產生與二維平面影像相對應之深度資訊圖。主要使用Sobel邊緣偵測法根據不同的閥值對影像做物件切割的動作,接著使用Z.S.細線法,將邊緣資訊縮減為單一像素的線條,此時影像會轉變為網格狀,再搭配由下至上,深度資訊由近至遠的漸層深度資訊圖,依照相對的位置將深度資訊填滿網格,自動形成一張相對應之深度資訊圖,最後,我們合併不同的閥值所產生的深度資訊圖,即為最終的相對應深度資訊圖。而我們所要產生相對應之深度資訊圖的二維平面影像,是選用故宮博物院所提供古典文獻以及古典文物來作為研究的對象,主要是在於古典文獻文物有相當悠久的歷史,其珍藏的數量非常龐大,且鮮少人以此做為研究對象。

並列摘要


In this thesis, we proposed a two dimensional to three dimensional image conversion chip and system design of digital archives for classical antiques and document. At first, we use sobel edge detection method to segment the object for image of classical antiques and document. Then, Z.S. thinning method is adopted to reduce width of object’s boundary. After the processing, the image will be transformed into grid image. Next, we fill the depth value to relative position of the grid image by gradient depth map. Finally, we merge two depth maps according to two kinds of threshold value and perform two dimensional to three dimensional image conversion chip and system design of digital archives for classical antiques and document.
