Claim 7:
8. A system for detecting driving markings visible in a plurality of light spectrums, comprising:
at least one processor deployed in a vehicle configured to execute a code, the code comprising:
code instructions to receive a plurality of images captured in a plurality of spectral ranges, the plurality of images depicting at least part of driving assistance markings painted on at least one element of at least one road segment with at least one paint material characterized by reflecting light deviating, in the plurality of spectral ranges, by more than a certain value from the light reflected by a surface of the at least one element;
code instructions to analyze at least one first image of the plurality of images captured in a first spectral range of the plurality of spectral ranges to identify at least part of the driving assistance markings in of the first spectral range;
code instructions to analyze at least one second image of the plurality of images captured in at least one second spectral range of the plurality of spectral ranges to identify at least part of the driving assistance markings in of the at least one second spectral range;
code instructions to identify aggregated driving assistance markings by correlating between the at least part of the driving assistance markings identified in the first spectral range and at least part of the driving assistance markings in the at least one second spectral range; and
code instructions to output the aggregated driving assistance markings.
