Abstract
In a device for the contactless measurement of an object surface (19), at least three stripe patterns (21, 22, 23) can be projected on the object surface (19, whereby the lines of the stripe patterns (21, 22, 23) are aligned at angles to each other and projection axes are inclined in space in relation to the stripe patterns (21, 22, 23). By determining the phase positions of the measuring points on the object surface (19) in relation to each of the stripe patterns (21, 22, 23), the spatial measuring point coordinates can be determined by the projection from three different spatial directions at the stipulated angles and local frequencies of the stripe patterns in a computer unit of an evaluating device (27) in relation to a reference point located on the object surface (19).
