本論文設計並實作了一套以輪廓線為主的三維物件重建系統,幫助使用者重建出三維物件,此外,我們也發展了一套人體虛擬實境漫遊系統,讓使用者可以遊走於人體管道之中,藉此獲知相關的醫學常識。
在重建三維物件方面,我們提出了一套以輪廓線為基礎的三維物件重建演算法,並評估及比較其結果。目的是要讓重建出的三維物件更符合實際世界的情況。當建立好三維物件之後,本論文也設計並實作一些工具去針對三維物件做處理及測量。
藉由三維物件重建系統讀取一系列的人體二維剖面圖,在圖上繪製器官輪廓線並建成三維物件後,便可以擁有一套完整的人體管道模型。而這些管道資料,便是我們的另一套實作品 - 「人體虛擬實境漫遊系統」的輸入。在此套系統中,使用者有如置身於人體中,透過一些簡單的操作,便可在管道中漫遊。在移動的同時,我們也提供了所在位置的二維剖面圖等醫學知識給使用者。
We design and implement a contour-based 3D reconstruction system to help users reconstruct 3D objects. Besides, we develop a virtual reality navigation system in human body. Users can navigate the human body and learn some medical knowledge.
To reconstruct 3D objects, we present a contour-based 3D reconstruct algorithm. We display the results and evaluate the algorithm. Our purpose is to make the 3D objects more similar to the real world. We also design and implement some tools to manipulate 3D objects and make measurements of the 3D objects.
Users can use the system to read a series of human cross-sectional image files and draw the contours of the organs in the images to reconstruct the 3D objects. Therefore, we can obtain 3D human organ models. The 3D models can be used for the 3D scene of the navigation system. In the system, users can navigate through the human body with some simple man-machine interfaces. Besides, we also provide some medical knowledge such as the 2D cross-sectional images to the users while they are navigating so that the users will not get dis-oriented.
