Without complex 3D reconstruction processes, the implementation of the pointing system is based on image analysis, homography, and 3D geometry.

此系统避开以往复杂的三维重建方式，改以影像分析技术，平面投影转换及三维几何等数学理论，作为系统实作的基础。

In this thesis, we implement a real-time pointing system which, unlike ordinary 3D reconstruction approaches, uses homography and some known 3D reference planes to reconstruct the target point without using camera's intrinsic parameters and orientation. The basic concept is quite intuitive and easy to realize.

本论文中实作了一个即时的指向系统，不同於其他相关的研究中使用传统三维重建的方法来找出指向点，我们没有使用到相机的内部参数以及朝向等资讯，而是利用平面投影转换以及一些三维空间内的平面关系作为系统实作的基础，概念上较为直觉而且也相对地容易理解。
