Abstract:
1. A method for blocking dazzling, comprising: detecting, by a dazzling detector, a facial area and an eye area of a driver's facial image; detecting, by the dazzling detector, an incident area to which direct sunlight is incident in the facial area; determining, by the dazzling detector, whether dazzling is affecting the driver's driving ability when the eye area is included in the area to which the direct sunlight is incident; recognizing, by an incident area shape recognizer, a shape of the incident area; detecting, by an incident direction detector, an incident direction based on a shape of the recognized incident area and the detected facial area, wherein the detecting of the incident direction includes: approximating, by a boundary line approximator, a boundary line between the shape of the recognized incident area and the detected facial area to a straight line; determining, by a slope determiner, the incident direction of the direct sunlight by calculating a slope of the straight line; and operating and adjusting, by a blocking apparatus driver, a blocking apparatus to block direct sunlight from the detected incident direction, wherein the determining of the incident direction includes: determining the incident direction as lateral incidence when the slope of the straight line satisfies a vertical range, determining the incident direction as front incidence when the slope of the straight line satisfies a horizontal range, and determining the incident direction as lateral and front incidence in cases other than the first and second determination.
