SYSTEM AND METHOD FOR AUTOMATICALLY IDENTIFYING AND MATCHING A COLOR OF A STRUCTURE'S EXTERNAL SURFACE
First Claim
1. A computer-implemented method for matching the color of siding, the method comprising:
- receiving, via one or more processors from a digital image of a siding sample, (i) a region of interest, and (ii) a region of reference color corresponding to a color reference card positioned within the digital image, the color reference card having a predetermined color value, the region of interest indicating a portion of the siding sample having a desired color value to be matched;
adjusting, by one or more processors, a color balance of the digital image based upon the predetermined color value to provide an adjusted desired color value to be matched within the region of interest;
determining, via one or more processors, a desired color point in a color space, the desired color point corresponding to the adjusted desired color value;
determining, via one or more processors, a plurality of spatial distances between the desired color point and a plurality of reference color points within the color space, each of the plurality of reference color points representing a quantified color estimate of a respective replacement siding product from among a plurality of replacement siding products;
identifying, via one or more processors, one of the plurality of replacement siding products having a respective desired color point associated with the shortest spatial distance from among the plurality of spatial distances as the replacement siding product having the closest matching color to the siding sample; and
calculating, via one or more processors, a confidence level indicative of how similar the quantified color estimate for the replacement siding product having the closest matching color to the siding sample is to the adjusted desired color value based upon the shortest spatial distance.

Abstract
The method and system may be used to provide an indication of a color value for a particular siding sample and to color match a specific siding product to the color value of the siding sample. The system receives a digital image of a siding sample and a desired color value to be matched. A color query module plots this desired color value as a desired color point in a multidimensional color space together with a plurality of color reference points. Each color reference point represents the color value of an existing siding product. The system determines a “distance” between the desired color point and each plotted color reference point within the color space and identifies the siding product associated with the color reference point that is located the shortest distance to the desired color point within the color space.
