Abstract: 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.

Abstract: Disclosed is a method for reading a two-dimensional code (17) by means of a camera (1) used for the three-dimensional optical measurement of an object using triangulation. Said method comprises the steps of placing the camera (1) above the two-dimensional code (17), having a white light source (5) of the camera (1) illuminate the code (17), having the camera (1) capture an image (18) of the code (17), and having an arithmetic unit (6) read data encrypted in the code (17) from the image (18) of the code (17).
