Abstract:
The method of the invention comprises: obtaining a sequence of at least two images, with different levels of illumination; extracting the region containing the sign in the image; calculating the luminance values of the signs; and obtaining the difference in luminance of the sign corresponding to the two levels of illumination. The value obtained is the luminance of the sign ( 11 ) corresponding to an illumination equal to the difference between the illuminations, or additional illumination. This result is based on the additive property of luminance, according to which the luminance of a sign is the sum of the luminance produced by each source of illumination. A basic illumination device ( 5 ), an additional illumination device ( 7 ), at least one camera for taking images, and image recording, positioning and synchronism systems are required to implement the method.

Claim (Index 10):
A luminance detection system connectable to a vehicle and operable while the vehicle is moving along a roadway, the luminance detection system comprising:\n a light source configured to illuminate a road marking positioned along the roadway, the light source being separate and distinct from a pair of headlights of the vehicle; a first camera configured to obtain a first image, the first image including the road marking; a second camera configured to obtain a second image, the second image including the road marking; a processor configured to:\n calculate a distance between the vehicle and the road marking based on the first image and the second image; \n apply a luminance transform to convert pixel values to luminance levels representative of the road marking, wherein the pixel values are from at least one of: the first image and the second image; \n calculate a luminance value representative of a luminance of the road marking based on (i) the distance between the vehicle and the road marking and (ii) the luminance levels representative of the road marking.
