基於紅外光源之駕駛者眼球偵測系統

Using IR Illuminator for Driver's Eye Detection System

本文提出應用紅外線光源於駕駛者疲勞偵測方法，利用紅外線光源及攝影機拍攝駕駛者眼睛偵測開合狀況判斷疲勞程度。藉由紅外線光源對瞳孔和虹膜對紅外光吸收率的顯著差別而得到瞳孔影像，再藉由影像處理區域改變，得到駕駛者在一定範圍內偵測眼球活動、追蹤分析眼瞼狀態和眼球眨眼的注視位置。最後，經由統計處理得到瞳孔大小的最大值和即時的瞳孔閉合百分比，同時利用SVM分類器方法判斷駕駛者的疲勞程度。 This paper presented a using IR illuminator for driver's eye detection system. The device uses IR illumination and camera acquires the eyes of driver to detect opening or closing driver drowsiness detection. The IR illumination creates the bright pupil effect which creates a nearly perfect circle. The system searches, tracks and blinks for the eyes location in each frame. Finally, detect the size of pupil and opening or closing driver eye and classify driver drowsiness using SVM classifi cation.
