臺灣博碩士論文加值系統

本論文主要以集成攝影立體顯示技術做為研究系統，藉由電腦模擬以及實驗的方法達到影像重建的目的。在此實驗當中，我們利用傳統的陣列式透鏡去獲得物體的影像單元，並使用CCD拍攝重組影像，再利用相同的系統架設獲得重建影像。我們也利用Matlab程式建立了一套模擬系統，透過此系統，能夠成功地模擬並重建立體影像，甚至可以獲得各視角的立體影像資訊，從我們的研究可得知，實驗結果與電腦模擬是相符的。對於集成攝影的廣視角系統，透鏡單元需要有較小的光圈值(透鏡焦距與透鏡直徑的比值)。

In this thesis, we mainly study the autostereoscopic characteristics in integral photography system by means of computer simulation and experiments. Elemental images of objects are generated with a commercial lens array and caught with a CCD camera for experiments. We also build up a program with Matlab software to simulate and interpret the optical phenomena in integral photography including viewing angle limitations and viewing depth effects. From our results, it shows that simulation and experiments are compatible. For wider viewing angle of integral photography, the characteristics of lens array with smaller f-number are needed.
