Abstract: A system and method of characterizing a color variation of a surface includes a device having a light source and a plurality of sensors positioned at respective viewing angles. An algorithm is stored on and executable by a controller to cause the controller to direct a beam of light at the measurement location with the light source and measure the light leaving the measurement location with the sensors at a plurality of azimuth angles to obtain respective measured color values. The controller is configured to define a color vector function F(θ, φ) to represent the color variation of the surface. The controller is configured to determine the color vector function F(θ, φ) based at least partially on the respective measured color values. The system allows for a representation of color space of a surface at any azimuth and viewing angle.

Abstract: A measurement system receives design values specifying measurement points of a first design and values corresponding to measurement points of a first part manufactured according to the first design using a first process. The system calculates a reference point of the first part and translates the received values based on a difference between reference points of the first part the first design. The system includes a rotation module that applies a rotational transformation with a first angle to the translated values. The system includes an error minimization module that determines a first value for the first angle that minimizes deviations between the transformed values and the specified design values. The system includes an error determination module that computes deviations between the transformed values and the specified design values. The system includes an analysis module that calculates a process metric of the first process based on the computed deviations.

Abstract: A method can be used to coat a vehicle body. The method includes: (a) providing a metallic substrate; (b) applying a foundation coat over the metallic substrate; (c) applying a basecoat over the foundation coat; (d) applying a clearcoat over the basecoat; and (e) heating the metallic substrate, the foundation coat, the basecoat, and the clearcoat simultaneously in order to cure the foundation coat, the basecoat, and the clearcoat. The foundation coat is inherently UV stable and is configured to protect the vehicle body against corrosion, and bonds the metallic substrate to the basecoat and the clearcoat. A vehicle body includes a metallic substrate, a foundation coat bonded to the metallic substrate, a basecoat disposed over the foundation coat, and a clearcoat disposed over the basecoat.
