Texture analysis of a coated surface using electrostatics calculations

摘要

Reflectance data from a target coating generated by a paint spectrophotometer is analysed to produce so called electrostatics data by treating portions of the reflectance data as electrical point charge and“solving”the electrostatic Coulomb’s Law equations. The electrostatics data is in turn compared to similarly derived electrostatics data stored in an empirical dataset. The processor generates a coating formulation that is the same as or substantially similar in appearance to the target coating on the basis of a comparison of the calculated and stored electrostatics data.
