Abstract
Disclosed is a drowsiness prevention system installed in a vehicle. The drowsiness prevention system includes: a light emitting unit irradiating infrared light toward the driver's iris, an infrared camera capturing images of the driver's iris, and a warning sound generating unit determining the driver to be drowsy to generate a warning sound when the driver's iris is not detected from the images captured by the infrared camera within a preset reference time. The distribution angle pattern of the infrared light is inclined from a central axial line. The light emitting unit is mounted in an area other than the driver's front area.
