Abstract
The disclosure relates to an arrangement and a method for capturing coordinates of an object surface by triangulation. At least two partial light patterns are generated representing a decomposition of a corresponding basic light pattern. The partial light patterns are separately projected onto the object surface, an image of the object surface is captured during the projection of one of the partial light patterns, and components of the total intensity of the captured images are ascertained. A balance of direct and indirect intensity components is established per image and for each pixel under the assumption that the indirect intensity components in all images are equal. A reflection image is established based on the direct and/or indirect intensity components which approximates the image that would be capturable during a projection of the basic light pattern without indirect intensity components. Based on the reflection image, coordinates of the object surface are ascertained.
