摘要： Calibration devices for calibrating a camera, systems for computer-aided determination of hair colour information, and methods for calibrating a camera are provided herein. In an embodiment, a method for calibrating a camera includes recording a digital image of a piece of calibration information on a fibre from a plurality of fibres from natural hair or fibres that resemble natural hair by employing a camera. The fibre is identified in the digital image by employing a marker. A plurality of colour values are determined for a plurality of reference colours as the calibration information on the fibre in the digital image, wherein a reference colour value is assigned to each reference colour. The respective determined colour value for the plurality of the determined colour values is assigned to the respectively assigned reference colour value for the plurality of reference colour values.

摘要： Disclosed is a method for organizing a substantially uniform system of colorimetry comprising the steps of (i) taking a pseudoinverse of a matrix containing intensity values for an existing non-uniform color-matching functions; (ii) optionally normalizing the pseudoinverse matrix from step (i); (iii) empirically determining an opponency transformation matrix based on a plurality of substantially uniformly spaced color standards; (iv) transforming the matrix from step (ii) to a color opponency color coordinate utilizing the opponency transformation matrix from step (iii) to obtain a Red-Green, Yellow-Blue and Lightness (RG, YB and LT) color matching functions; and (v) transforming the RG, YB and LT color matching functions from step (iv) non-linearly to color matching functions that produce colors recognizable as being uniform by human vision; wherein after step (v) the existing non-uniform color matching functions are transformed into substantially uniform color matching functions.

摘要： A method is provided for providing a set of ingredients for manufacturing of a dental prosthesis covering. The method comprises receiving a background colour value providing information on a colour of a background substrate on which the prosthesis is to be provided, receiving an appearance colour value providing information on an appearance colour of the prosthesis and receiving a thickness value providing information on a thickness of the dental prosthesis covering. In an electronic memory, a first ingredient record is looked up comprising first ingredient value, based on the measured background value and the measured appearance colour value. The first ingredient values are adjusted in an electronic processor adjusted based on the thickness value and through electronic output means, the adjusted ingredient data is provided. By adjusting ingredients for thickness, a more natural appearance may be achieved.

摘要： A system for detection and coating analysis that comprises a digital camera and a light-based protractor positioned adjacent to or on a physical coating surface. The system identifyies a particular angular indication being displayed by the light-based protractor. The system then identifies a target color of the physical coating surface and identifies one or more target coating texture characteristics of the physical coating surface. Additionally, the system identifies a proposed coating that comprises a proposed color that matches the target color and proposed coating characteristics that match the one or more target coating texture characteristics. The system then displays, on a user interface, the proposed coating.
