Zusammenfassung:The invention relates to a device for optical 3D measurement of an object using an optical depth-scanning measurement method, comprising at least two light sources, at least two optical means for producing textured patterns and at least one recording means. A first pattern is produced with the aid of a first optical means and projected onto the object to be recorded as a first projection beam. A second pattern is produced with the aid of a second optical means and projected onto the object to be recorded as a second projection beam. The imaging optics is controlled and adjusted in such a way that a sharp focal plane is incrementally varied along an optical axis of the device.
