Abstract

The invention describes a method of analyzing a light distribution of a vehicle headlight. The method determines a cutoff line based on a brightness distribution within a column of an image of the light distribution, the column being perpendicular to a horizon in the image. The method compares the cutoff line with a reference cutoff line and uses the deviations revealed by such comparison to attribute a reduced quality of the light distribution to a particular one of several possible causes. The invention further describes a vehicle headlight analyzer which is arranged to perform the method. The invention finally describes a corresponding computer program product comprising code for executing the method on a processing device.
