碩士 === 國立成功大學 === 電腦與通信工程研究所 === 95 === 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.
