ASSESSMENT OF THE APPLIED HIDING OF A COATING
A hiding value of a coating on a coated surface is assessed by assessing a reflectance of a multiplicity of pixels of an optically scanned image of the coated surface, and, based at least in part on the reflectance of each pixel of the multiplicity of pixels, assessing a hiding value of the coating on the coated surface.
1 . A method of assessing a hiding value of a coating on a coated surface, the method comprising:
assessing a reflectance of a multiplicity of pixels of an optically scanned image of the coated surface; and
based at least in part on the reflectance of each pixel of the multiplicity of pixels, assessing a hiding value of the coating on the coated surface.
2 . The method of claim 1 , further comprising optically scanning the coated surface to yield the optically scanned image.
3 . The method of claim 1 , wherein assessing the hiding value of the coating comprises assessing a percentage of pixels having a reflectance of at least 70%.
4 . The method of claim 3 , wherein assessing the hiding value of the coating comprises assessing a percentage of pixels having a reflectance of at least 80%.
5 . The method of claim 1 , further comprising assessing a thickness of the coating on the coated surface corresponding to each pixel of the multiplicity of pixels.
6 . A method of assessing a hiding value of a coating on a coated surface, the method comprising:
assigning a reflectance value to each pixel of a multiplicity of pixels of an optically scanned image of the coated surface; and
assessing a percentage of the reflectance values at or above a threshold reflectance value.
7 . The method of claim 6 , wherein the optically scanned image is a grayscale image.
8 . The method of claim 7 , wherein assigning the reflectance value to each of the multiplicity of pixels comprises converting a gray value associated with each pixel of the multiplicity of pixels to the reflectance value.
9 . The method of claim 6 , further comprising removing reflectance values outside a selected range from the reflectance values before assessing the percentage of the reflectance values at or above the threshold reflectance value.
10 . The method of claim 6 , wherein the percentage of the reflectance values at or above the threshold reflectance value corresponds to a hiding value of the coating.
11 . The method of claim 6 , further comprising, based at least in part on the reflectance values, calculating a thickness of the coating corresponding to each pixel of the multiplicity of pixels.
12 . The method of claim 6 , further comprising assessing a percentage of the reflectance values in one or more ranges of reflectance values less than the threshold reflectance value.
13 . The method of claim 12 , further comprising graphically displaying the percentage of reflectance values in the one or more ranges of reflectance values and above the threshold reflectance value.
14 . A computer-implemented method of generating a hiding value of a coating on a coated surface, the method comprising:
generating by one or more computer systems a reflectance value of a multiplicity of pixels of an optically scanned image of the coated surface;
based at least in part on the reflectance of each pixel of the multiplicity of pixels, generating by one or more computer systems a hiding value of the coating on the coated surface; and
storing, on a hardware storage device, reflectance data representing the reflectance value in a first field of one or more data records and hiding data representing the hiding value in a second field of the one or more data records.
15 . One or more machine-readable hardware storage devices storing instructions that are executable by one or more processing devices to perform operations comprising:
generating a reflectance value of a multiplicity of pixels of an optically scanned image of a coated surface;
based at least in part on the reflectance of each pixel of the multiplicity of pixels, generating a hiding value of a coating on the coated surface; and
storing, on a hardware storage device, reflectance data representing the reflectance value in a first field of one or more data records and hiding data representing the hiding value in a second field of the one or more data records.
