Abstract
The formation of a two-dimensional color pattern (9) consisting of colored pattern elements (10) enables a particularly compact and faultproof color pattern for a coding to be provided. The aim of the invention is to determine the projection angle PHI for a pattern element in the picture record of the two-dimensional color pattern projected onto an object. Three dimensional data of an object point can be calculated by subsequent triangulation at a known position of the projector and a camera.
