Without complex 3D reconstruction processes, the implementation of the pointing system is based on image analysis, homography, and 3D geometry. 此系統避開(kāi)以往復雜的三維重建方式，改以影像分析技術(shù)，平面投影轉換及三維幾何等數學(xué)理論，作為系統實(shí)作的基礎。
The image processing steps and methods of image analysis for the 3-D positioning processes used in this thesis will be introduced in the fallowing chapters. 在接下來(lái)的章節中將會(huì )介紹本論文中三維定位過(guò)程里用到的影像處理步驟以及影像分析的方法。
