Abstract:
1. A method for determining at least one threshold value S for distinguishing, in the dark, between oncoming vehicle lights and reflectors that are recorded as light spots by a camera sensor oriented towards the surroundings of a vehicle, comprising: recording a series of images of the surroundings of the vehicle with the camera sensor; tracking at least one light spot in the series of images is tracked; determining, after tracking of the at least one light spot is completed, at least one parameter of the at least one light spot in the series of images; and adapting a threshold value S by: including the determined at least one parameter value in a frequency distribution n for the parameter of several light spots that all have been tracked over several images; determining, from the frequency distribution of the previously determined parameter values, a threshold value S fixing, after temporal filtering, a new threshold value S for distinguishing between reflectors and vehicle lights.
