長時間開車很容易造成身體上的疲勞，如果在身體疲 勞的狀態下開車很容易發生事故，因此我們期望開發一 駕駛瞌睡偵測系統，能在駕駛人打瞌睡時發出警示，以 降低交通意外發生的機會。本論文提出一具強健性之駕 駛瞌睡偵測系統，此系統對環境光線要求不高，且能容 許駕駛者配戴太陽眼鏡或墨鏡，避免了現有植基於眼睛 閉闔偵測的瞌睡警示系統的使用限制，經實驗證實本系 統能以相當強健的性能進行運作。

Long time to drive a car is likely to cause physical fatigue and results in accident. Hence, we want to develop a system that can alert the driver when he is dozing to reduce accidents. This study presents a new driver doze detection scheme by judging if the driver’s head rotates. Hence, our system can successfully operate even the driver wear sunglasses. When the system finds the driver keep no head rotation for a predefined period it will alert the driver.
