    摘要: The invention relates to a method for the optical three-dimensional measurement of a dental object, wherein a first region of the dental object is measured using a first optical three-dimensional measurement method, wherein the first optical three-dimensional measurement method is based on a triangulation method and on a fringe projection method. According to the invention, a powdering occurs at least on the first region, wherein first image data are generated. Using a less precise, second optical three-dimensional measurement method, a second region of the dental object is subsequently measured without previous powdering, wherein second image data are generated. Afterwards, the first image data are combined with the second image data to form an overlapping three-dimensional exposure.

    摘要: A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.

    摘要: The invention relates to a measuring device and a method based on a confocal microscopy principle. The inventive device comprises a light source (1), a diaphragm unit (3) for limiting a beam, an imagine optical system (4) for focusing the light (5) which is irradiated by said source on a measurable object (6) and passes through said diaphragm unit. Said device also comprises an optical system (10) for receiving the light (5) reflected from the object and passing through said optical system or another diaphragm unit disposed in an observation beam (7) and an image receiver (10) which is provided with at least two radiation-sensitive sensor elements (13, 14) (pixel). Said invention is characterised in that, in order to obtain the image of an altitude information-containing measurement, the device is also provided with means (11) for modifying the beam optical path length disposed between the light source (1) and/or the image receiver (10), on one side, and the object (6) on the other and the optical distance (d) of a focal point is modifiable in a predetermined manner. In addition, said intention makes it possible to influence the dependence of an accumulation of charges (Q13, Q14) in at least two sensor elements (13, 14) on the light intensity of the observation beam (7) during the exposure time in such a way that a correlation associated with the optical distance (d) of an image plane can be carried out by the imagine optical system (4), thereby making it possible to reconstitute the altitude co-ordinate (zs) of the object by distributing the intensity values obtained during the exposure time from at least two sensor elements (13, 14).

    摘要: A blank for producing a formed dental part has closely toleranced reference faces being arranged at one end of a blank member lying opposite a retainer projection. The reference faces comprise two surfaces lying opposite one another that have a defined spacing from one another with close tolerances. The surfaces are advantageously formed by a reference part with a cylindrical cross section that is secured onto the blank member.
