Abstract: A method for determining a level of degradation of a road marking is executed by a determination unit. The method includes generating a plurality of reference images by an image capturing device photographing a reference road marking with a plurality of shutter speeds. The reference images are stored in a database. The method further includes generating an image by the image capturing device photographing an examined road marking according to a selected shutter speed, retrieving one of the reference data from the database that has the same shutter speed as the examined road marking by a processor, and performing a difference determination procedure between the retrieved reference data and the examined data by the processor, and outputting a determined result of the level of degradation of the examined road marking by the processor. As such, accurate determination on the level of degradation of the examined road marking can be achieved.
