Abstract
A system and method include receiving target image data associated with a target coating. A color model and a local color model are used to predict color differences between the target coating and a sample coating. The color model and local color model includes a feature extraction analysis process that determines image features by analyzing target pixel feature differences within the target coating. Performing an optimization routine upon the color differences for determining automotive paint components for spraying a substrate.
Claims20
A system for color matching involving automotive paints, said system comprising:
- a storage device for storing instructions;
- one or more data processors configured to execute instructions to:
- receive a target image of the target coating, wherein the target image comprises target image data;
- apply a color model and a local color model to predict color differences between the target coating and a sample coating,
- wherein the input to the color model and local color model include actual color differences between the target coating and the sample coating;
- wherein the color model and local color model includes a feature extraction analysis process that determines image features by analyzing target pixel feature differences within the target coating, and
- optimize the predicted color differences using a relaxed constraint process;
- wherein the optimized color differences determine automotive paint components for spraying a substrate.
A method of matching a target coating comprising:
- receiving, by one or more data processors, a target image of the target coating, wherein the target image comprises target image data;
- applying, by the one or more data processors, a color model and a local color model to predict color differences between the target coating and a sample coating,
- wherein the input to the color model and local color model includes actual color differences between the target coating and the sample coating;
- wherein the color model and local color model include a feature extraction analysis process that determines image features by analyzing target pixel feature differences within the target coating, and
- optimizing, by the one or more data processors, the predicted color differences using a relaxed constraint process;
- wherein the optimized color differences determine automotive paint components for spraying a substrate.
