PURPOSE: A drowsiness detection device and method thereof are provided to exactly detect sleepiness of drivers by increasing recognition ratio of an eye region even in a low-light state. CONSTITUTION: A drowsiness detection device comprises a photographing unit, a drowsiness determination unit(200), an anti- drowsiness driving unit. The photographing unit makes a video of drivers by using visible rays and transfers the video to the drowsiness determination unit. The drowsiness determination unit detects eye region and processes the video into signals. The drowsiness determination unit extracts linear components by doing Hough-transform on the detected eye region. The drowsiness state of the drivers is determined by the number of the linear components. The anti- drowsiness driving unit operates to prevent the drivers from sleeping if the drowsiness state is detected. |
