中文摘要
在電腦視覺的與機器應用領域中，三維物體的辨識與立體視覺是一項重要的工作。在本論文中，主要辨識具簡單幾何形狀的3D物件，藉由目標物顏色的特徵透過影像處理來擷取目標物的影像。利用三角網格建立3D物件與少許的資料庫，從此資料庫中找尋目標物初始的旋轉方向，並藉由旋轉3D物件與目標物匹配，找出目標物的角度。

Abstract
3D object recognition and stereo vision are crucial techniques in computer vision and robotic application. In this research, we use triangular meshes to build a database with small number of 3D models with some initial orientations to find object with simple geometric shape. From the database, finding the approximate orientation of the object first, and constructing models with changing viewing angle around the initial orientation. Finally, we find the correct orientation of the object .
