　　移動物的偵測技術在近代中被研究的相當多，然其在影像的處理方面，仍存在著許多的問題，其中又以像差的影響最無法避免，而像差的影響會使得影像處理過程中產生雜訊，進而影響偵測的準度，所以解決像差的問題可以說是刻不容緩的事情，現行關於像差消除的技術中以影像補償最為常見，但其旨在調整像差大小而非去除像差，本論文擬用光線追蹤的原理，徹底消除像差的影響，進而提高移動物偵測的準確度。
　　本文首先簡介相關數學模型、幾何光學原理，進而利用數學模型推導，來表示光線在空間中的行進，建構整個光線追蹤的理論，再將其利用在本文所使用的實驗方法中，最後以模擬的模型及實際上的操作，對於本方法作一個討論與比較，並提出相關應用與發展。

　　The technology of motion detection has been extensively studied lately. But there are still some problems regarding image processing. The noise of the image processing, so-called aberrations, will decrease the recognition of motion detection for moving object. Most of the existing techniques for solving this problem rely on getting continuous image in a vary short time. For example, take 24 images in one second, so that the difference of background images formed by aberrations can be almost ignored. But for high speed moving camera, we must take more images in one second, even more than 100 images, in order to eliminate the difference of background. This paper proposes a methodology of solving aberration problems by ray tracing technique. This method can avoid the influence of the aberration by getting the virtual image in object side. It can minimum the noise and increase the recognition of detection system.
