在疲勞駕駛檢測中,對眼部狀態的判斷是關鍵的步驟之一。為了對眼部狀態進行有效
的識別，本文提出了一種新穎可行的眼部狀態定位識別方法。利用灰度投影曲線與灰度直方圖預測初始閾值思想進行人眼檢測。試驗結果表明，該方法易于實現,準確度高，速度快, 具有計算簡單、快速、有效等優點,可滿足疲勞駕駛監測系統中實時檢測的要求。關鍵詞：灰度投影曲線；灰度直方圖；人眼定位；疲勞檢測

Abstract：During Driver Fatigue State Surveillance, Eye State Recognition is one of the committed steps.In order to recognize the eye state effectively，a novel method of eye state position recognition is proposed. Using gray project curve and VGH to detect the human-eye. Theexperimental results indicate that this method bare low complexity, high accuracy, high speed, easily and effectively to calculate. It satisfiers the real time detection during driver fatigue monitoring system.
