相機校正與投影機校正 在三維掃描上的應用

Abstract

在本篇論文中，我們提出一個利用投影機-相機系統以量測物體三維形貌的演算法。為了達到此目的，相機與投影機的特性需要透過校正而得，以及利用結構光的技術來獲取投影機像素與相機像素之間的對應關係。最後，物體的三維形貌則是利用極線幾何來建構。

In this thesis, we propose a 3D point cloud construction algorithm via using projector-camera system. In order to achieve this purpose, the camera and projector property should be accurately estimated by using calibration algorithm. The relationship between camera pixel and projector pixel can be linked by structure light technique. Finally, the object shape can be reconstructed in the form of a point cloud by considering the epipolar geometry.
