柱狀透鏡之即時裸視立體顯像操控之實現

Abstract

近年來立體顯示技術蓬勃發展，尤其是在電影娛樂上，立體顯示更是一股潮流。但是我們觀賞3D畫面時，通常需要戴上一副3D眼鏡，戴久後常常會造成不適感。另外，現今醫生在替病患診斷頸部腫瘤時，是以雙手直接去按壓發病部位做觸診，若是能配合一個頸部周圍的3D空間結構模型來診斷，將有助於醫生及病人對病情的了解。而目前學術上研究3D建模的文獻通常都侷限在2D畫面中的虛擬3D，而不是實際的3D畫面。有鑑於此，本篇論文實現了一個即時裸視立體顯像操控程式做為應用例，建造了虛擬3D物體，三維空間任意視角轉動、橫切面截取輪廓線以及物件個別分離觀看等功能，最後並將此虛擬3D物體以裸視3D的方式顯像出來。本論文貢獻如下所述，首先，本論文將此套裸視立體顯像操控架構實現出來，為往後的生醫研究者提供了一個應用例可供參考或套用。第二，本論文將此操控程式的輸出畫面結合裸視3D，提供使用者一個嶄新的立體視覺效果，跳脫出傳統的2D畫面。第三，除了據有深度資訊的裸視3D模型外，此應用例程式還有另外建立對應的平面虛擬3D模型，使用者能夠依據上述的操作功能，將兩種影像同時做仔細的檢查與比對，增加使用者對建立模型的三維空間結構和排列情形更加了解。

3D stereoscopic technology has been developing vigorously in recent years. Especially in movie entertainment, 3D stereoscopic technology is a trend. We usually need to wear a pair of 3D glasses when we watch the screen. However, after wearing for a long time, we often feel uncomfortable. Besides, in the diagnosis of cancer for patients, doctors often use their hands directly to press the diseased part of human body such as neck. If the diagnosis of cancer can operate with a 3D structure model around the diseased part, doctors and patients will understand the disease easily. Besides, academic literatures for constructing 3D model are usually limited in 3D virtual environment rather than 3D stereoscopy. In view of above, we realize a manipulation on real-time naked-eye 3D vision program based on lenticular lenses and use the program as an application example. In this program, we construct two virtual 3D objects, and we can control these objects doing arbitrary angle rotation in three dimensional space, intercepting their contours and separating the objects individually. The contributions of this paper could be summarized as follows. First, in this paper, we realize the manipulation on real-time naked-eye 3D vision program, and we use the program as an application example for future biomedical researchers to refer or apply. Second, in this paper, we combine naked-eye 3D vision with the output of the program, providing users with a new three dimensional visual effect rather than traditional two dimension vision. Third, in addition to constructing naked-eye 3D models owning depth information, we also construct the corresponding 2D models in this program. Therefore, with operating the interface’s functions described in above , users are able to carefully examine and compare the two kinds of models at the same time. Then, the users will more understand the 3D space structure of the models.
