To avoid accumulating errors and allow individual data to be rectified or corrected, first partial scans of the object are measured using at least one first sensor and are aligned relative to one another and/or corrected using second partial scans performed by at least two second sensors that are stationary relative to one another, and the individual data records for the combined data record are determined from the aligned and/or corrected partial scans.

摘要： A dental color system having primary and mixed colors with assigned coordinates in the CIElab color space, in which the colors of natural teeth are essentially located on coordinates within an ellipsoid-shaped space, which is assigned a longitudinal axis. In order for the color system to consist of a small number of primary and mixed colors and to allow an optimum color adaptation to the natural teeth surrounding the dental prosthesis, it is proposed that the primary colors consist of first primary colors and at least one group of second primary colors, that the coordinates of the first primary colors be positioned on the longitudinal axis of the ellipsoid-shaped space or on a base line extending from light to dark in the CIElab space, that the coordinates of at least one group of second primary colors be positioned in a plane that perpendicularly intersects the longitudinal axis or base line, and that the coordinates of mixed colors be intersection points of first and second straight lines, whereby at least one first straight line extends parallel to the longitudinal axis or base line and the respective second straight line is a connection between the coordinates of the first primary color and the second primary color.
