Abstract: The invention relates to a device for measuring color, luster and undulations on lacquered freeform surfaces at a predetermined target distance and symmetrically in relation to the measuring point normal lines at a measuring point. Said device is characterized by the provision of a measuring head that can be displaced in three dimensions by at least one motor and that comprises a measuring-head axis, a light emitter and a video camera. The light emitter is provided with a planar light pattern that is to be emitted along its illumination axis. An evaluation unit is provided for the light pattern (reproduction pattern) of the light emitter that is reproduced in the video camera, said evaluation unit emitting a control signal which is dependent on and formed from the distortion produced or the migration of the reproduction pattern. The measuring head is provided with a motor control, to whose input the control signal of the evaluation unit is applied and the measuring head is displaced in order to reduce the distortion or the migration of the reproduction pattern in the video camera to below a predetermined value, in such a way that both the measuring head axis coincides with the measuring point normal lines and the vertex of the angle formed by the illumination axis of the light emitter and the optical axis of the video camera coincides with the measuring point.

Abstract: In accordance with embodiments of the present invention, a goniospectrophotometer is provided for quickly obtaining a goniospectrum using a goniospectrophotometer. In some embodiments, a parabolic reflector is used to optically transform the angular space of a source at the parabola focus into a linear space and facilitate the use of a single diffracting element and area camera to simultaneously measure the angular spectrum of the source. Spectra corresponding to zenith angles of light reflection by the parabolic reflector can be acquired by a detector and analyzed in a computer.

Abstract: A method and apparatus for color matching are provided, in which paint recipe neural networks are utilized. The color of a standard is expressed as color values. The neural network includes an input layer having nodes for receiving input data related to paint bases. Weighted connections connect to the nodes of the input layer and have coefficients for weighting the input data. An output layer having nodes are either directly or indirectly connected to the weighted connections and generates output data related to color values. The data to the input layer and the data from the output layer are interrelated through the neural network's nonlinear relationship. The paint color matching neural network can be used for, but not limited to, color formula correction, matching from scratch, effect pigment identification, selection of targets for color tools, searching existing formulas for the closest match, identification of formula mistakes, development of color tolerances and enhancing conversion routines.
