Abstract:
A system for classifying different types of sheeting materials of road signs depicted in a videostream compares estimated retroreflectivity values against known minimum retroreflectivity values for each of a plurality of colors. Once a road sign has been identified in the videostream, the frames associated with that road sign are analyzed to determine each of a plurality of colors present on the road sign. An estimated retroreflectivity for each of the plurality of colors present on the road sign is then determined. By comparing the estimated retroreflectivity for each of the plurality of colors against known minimum retroreflectivity values for the corresponding color for different types of sheeting materials, an accurate determination of the classification of the sheeting material of the road sign is established. Preferably, certain conditions of gross failure of the sheeting material are filtered out before classification of the sheeting material is determined.

Claim (Index 11):
The method of  claim 2 , wherein the selecting step comprises: providing a computer model coding a function for obtaining a set of coordinates from each retroreflectivity profile, each coordinate comprising a pairing of a retroreflectivity value and an associated angular displacement, wherein the function associates the retroreflectivity value to the angular displacement; applying the computer model to the retroreflectivity profiles in the retroreflectivity pool to generate a set of reference coordinates for each retroreflectivity profile, each set of reference coordinates defining a characteristic curve having a characteristic shape; applying the computer model to the as-measured retroreflectivity profile to obtain a set of as-measured coordinates defining an as-measured performance curve having an as-measured shape; and selecting the characteristic curve having the characteristic shape which best approximates the as-measured shape.
