Abstract:
1. A dazzling determining system installed in a vehicle to be controlled for determining whether a headlight of the controlled vehicle dazzles a target person, a pickup unit being installed in the controlled vehicle and configured to pick up a rectangular image ahead of the controlled vehicle, the dazzling determining system comprising: an extracting unit working to extract a location of the target person in the rectangular image picked up by the pickup unit; a distance measuring unit working to actually measure a distance between the controlled vehicle and the target person; a first undazzled-area map storage unit working to store therein a first undazzled-area map, the first undazzled-area map including information indicative of a relationship between a boundary distance and each of a plurality of divided sections of the rectangular image, the boundary distance being defined as a maximum distance between the controlled vehicle and the target person such that, when the actually measured distance between the controlled vehicle and the target person is within the maximum distance, the target person is estimated to be dazzled by the headlight of the controlled vehicle; a first boundary distance extracting unit working to reference the first undazzled-area map to thereby extract, as a first boundary distance, the boundary distance corresponding to one of the plurality of divided sections, the one of the plurality of divided sections corresponding to the location of the target person; and a dazzling determining unit working to compare the first boundary distance with the actually measured distance to thereby determine that the headlight of the controlled vehicle is estimated to dazzle the target person when the actually measured distance is equal to or lower than the first boundary distance.
