基于DSP的疲勞駕駛預(yù)警系統(tǒng)的設(shè)計:本文描述了一個基于TI公司高速圖像處理芯片TMS320DM642的疲勞檢測預(yù)警系統(tǒng),用以判定駕駛員的疲勞程度,降低交通事故。本系統(tǒng)采用非接觸方法,先通過CCD攝像頭拍下駕駛員的面部圖像序列,然后檢測出臉部,從而定位眼睛,再利用PERCLOS判定疲勞狀態(tài)。本系統(tǒng)還結(jié)合免費的開源計算機視覺庫OpenCV來加快開發(fā)速度和降低開發(fā)成本。

Abstract: This paper describes a drowsiness detection system based on High-speed
DSP—TMS320DM642 from TI Inc .It can determine the driver’s level of attention, and reduce
the number of traffic accident. This system uses the untouched method. It gets video sequences of
a driver from the CCD camera, and than detects the face, eyelid. Finally, it uses the PERCLOS
criterion to determine the state of drowsiness. In addition, it is programed by Open Computer
Version (OpenCV), which can speeds up the development and reduces the cost.
