Abstract
A method for controlling an automotive lighting device. The method includes projecting a first light pattern, capturing an image of a region in front of the lighting device, obtaining a luminance map from the captured image, identifying objects in the luminance map and classify them as reliable or not reliable, according to at least one reliability criterion and modifying the first light pattern to modify the luminous intensity in at least one zone intended to project light on a non-reliable object.
Claims12
A method for controlling an automotive lighting device, the method comprising:
- projecting a first light pattern;
- capturing an image of a region in front of the lighting device;
- obtaining a luminance map from the captured image;
- identifying objects in the luminance map and classify them as reliable or not reliable, according to at least one reliability criterion by identifying contours and grouping contours in sets, so that each set of contours is defined as an object, where each reliability criterion includes choosing one reliability feature and compare the value of this reliability feature in each contour with the sum of the mean value plus one standard variation of this reliability feature in the whole set of contours;
- and
- modifying the first light pattern to modify the luminous intensity in at least one zone intended to project light on a non-reliable object.
