Patent ID: 8437918

Claim:
A system for correcting the orientation of a light source of a vehicle according to an attitude of said vehicle, said vehicle having a camera mounted in the vehicle for acquiring a succession of images representing a road scene unfolding in front of or behind the vehicle and a static correction device for static correction of the orientation of the light source in response to said attitude of said vehicle, and a first image processing unit producing a static signal corresponding to a first set of information relating to a static measurement of said attitude of said vehicle, said system comprising: a dynamic correction device for dynamic correction of the orientation of the light source in response to said attitude of said vehicle, said dynamic correction device having a second image processing unit for processing said succession of images acquired by the camera and producing a dynamic signal corresponding to a second set of information to respond to rapid variations in said attitude of said vehicle and further relating to a measurement of vertical movements and deviation of a framing of said succession of images acquired; and a data fusion device for combining said static signal corresponding to said first set of information and said dynamic signal corresponding to said second set of information and producing a light source orientation correction signal to correct the orientation of the light source to enable both a response to slow variations in said attitude of said vehicle and rapid variations in said attitude of said vehicle; wherein said light source orientation correction signal comprises a delay that begins when said rapid variations in said attitude of said vehicle begin and said dynamic signal having a dynamic correction signal delay that also begins when said rapid variations in said attitude of said vehicle starts, said light source orientation correction signal delay being greater than said dynamic correction signal delay.
