- the scope of application extends to the recording of digital dental impressions and jaw impressions, the assistance with the diagnosis, the monitoring of dental treatments as well as the reliable control of inserted implants.
- the scope of application extends to the recording of digital dental impressions and jaw impressions, the assistance with the diagnosis, the monitoring of dental treatments as well as the reliable control of inserted implants.
- Industrial engineering for example in the field of endoscopy, can generally be stereometrically measured objects that are difficult to access.
- a major disadvantage of known devices is that the recording devices (hand-held scanner), which penetrate to the objects to be imaged, usually unwieldy, bulky and
- the object of the invention is therefore to provide a device for
- This object is achieved in a device of the type mentioned in that a camera and / or a projector is arranged in the receiving area / are and that of
- Angle between 10 ° and 40 ° relative to the handle portion is inclined.
- FIG. 1 shows an embodiment of a handpiece for the invention from the side
- FIG. 2 shows the handpiece of Fig. 1 in plan view
- Fig. 3 shows the handpiece of Fig. 1 from the front
- FIGS. 1 to 3 shows the handpiece of FIGS. 1 to 3 in oblique view
- Fig. 5 is a partial exploded view of a
- FIG. 6 shows a longitudinal section through the embodiment of FIG.
- FIG. 7 shows a detail of FIG. 6,
- Fig. 8 is a section through the device along the line VIII-VIII and
- FIG. 9 shows a detail of an embodiment of a projector.
- a preferred embodiment of a device 1 for three-dimensional recording of objects 10, in particular teeth is shown, which has a receiving area 2 and a handle portion 3. Between receiving area 2 and handle area 3, a central area 5 is arranged in the illustrated embodiment. Since the central region 5 has smaller outer dimensions than the receiving region 2, the
- Receiving area 2 is a substantially conical
- At the front end 4 of the receiving area 2 is rounded.
- the receiving area 2 has a central axis 7, the
- the angle between the central axis 7 and the central axis 8 is according to the invention between 10 ° and 40 °, said angle ⁇ in the illustrated embodiment (with a central region 5) divided into two angles ß and ⁇ , wherein the angle ß between the central axis 7 of the receiving part 2 and the central axis 9 of the central region 5 and the angle ⁇ between the central axis 9 of the central region 5 and the
- the angle ⁇ is preferably between 3 ° and 15 ° and the angle ⁇ between 7 ° and 25 °.
- the length of the mounting area is preferably between 10 and 60 mm, since within these limits both a good
- an opening 12 (Fig. 5) is arranged in the receiving part 2, which is closed by a disc 13.
- a projector 14 in particular a Random pattern, directed to the object 10 and with a
- Camera system 15 images of the object 10 are recorded.
- the receiving area 2 is thus opposite the handle area 3 by an angle ⁇ between 10 ° and 40 ° counter to the
- FIGS. 5 to 8 show an embodiment of the invention in which the projector 14 emits a light beam 23 with a light source.
- the light beam 23 passes through one or more shown in Fig. 9 transparent support 36, 37, for example, slides on which one after a
- Random arranged pattern is arranged.
- the pattern preferably consists of substantially randomly distributed, possibly irregularly shaped dots and / or lines, which are subsequently projected onto the object 10, for example a tooth.
- a deflection mirror 26 which deflects a portion 23a of the light beam 23, in the embodiment of Fig. 7 the lowest part, to a first mirror 27, which directs the light on the object 10 subsequently.
- Embodiment of FIG. 7 the middle part, meets directly on a second mirror 28, from which the light is also directed to the object 10.
- the deflection mirror 26 is preferably a plane mirror, but could also be a convex or concave curved mirror if required.
- the two mirrors 27 and 28 are preferably biaxially convexly curved mirrors with identical or different radii of curvature in the two axes, with which the respective portion of the radiation beam 23 can be scattered more strongly as required.
- the arrangement and curvature of the deflecting mirror 26 and the first mirror 27 is so chosen that the part 23a of the light beam 23 in the image plane of the drawing has an opening angle ⁇ of about 30 °.
- the arrangement and curvature of the second mirror 28 is chosen by way of example so that the part 23b of the light beam 23 in the
- Image plane of the drawing has an opening angle ⁇ of about 25 °.
- the opening angle of the parts 23a, 23b of the light beam 23 in the direction normal to the image plane of the drawing can, by suitable curvature of the mirrors 27, 28 be equal to or different from the respective opening angle ⁇ , ⁇ lying in the image plane.
- a camera system 15 is arranged, which consists in the illustrated embodiment of two cameras 32, which stereoscopic images for
- the two optical axes 29, 30 of the mirrors 27, 28 span a plane ⁇ , the two cameras 32, more precisely their lenses 33, lying symmetrically on both sides of this plane ⁇ .
- the camera system 15 with the mirrors 26, 27 and their optical axes 29, 30 in a plane ⁇ which is a very precise image recording and thus
- Incisors can occur, can be avoided very reliably.
- a diaphragm 34 is disposed in the area above the deflection mirror 26, which blocks a third part 23c of the light beam 23 so that it does not cause unwanted reflections in the optics 33 of the cameras 32.
- the diaphragm 34 may also be omitted or arranged or shaped differently.
- All the mirrors 26, 27, 28, the diaphragm 34 and optionally also the camera system 15 can be adjustably fastened to corresponding holders 31 so that, if required, simple adjustment and / or calibration of the individual components is possible.
- all or even a portion of the components described above may be mounted and preset on a carrier system which may then be inserted into a recorder. The case of the
- Device 1 preferably consists of two housing halves 16, 17, which are designed mirror-symmetrically, whereby the
- illustrated inventive arrangement is a very compact and slim design possible, which for example can be very well integrated into a handpiece for three-dimensional recording of teeth.
- Projection and recording technique in an angled handpiece 1 incorporate, which is very slim and through the kink
- FIG. 9 schematically shows an embodiment of the invention in which two transparent carriers 36, 37,
- the pattern may consist essentially of randomly distributed, if necessary
- the light passes in the illustrated embodiment first through a lens 35, then through the two carriers 36, 37, and subsequently through a symbolically through a lens 38th
- the projector 14 of FIG. 9 can be used, for example, in a device shown in FIGS. 5 to 8, in which the light beam 23 is directed onto an object 10 via two mirrors 27 and 28. Since the light travels different distances, depending on whether it is either over the
- Deflection mirror 26 and the mirror 27 or the mirror 28 encounters the object 10, in the projection of the present on a support pattern on the object 10 blurring of one or the other or both projections can arise.
- Mirror 26, 27, 28 is not very large up to the object 10, for example, only a single carrier could be used, which either has stepped portions offset or indeed just but correspondingly strongly inclined to compensate for the path difference on average.
- a single carrier could be used, which is coated on different areas or sections respectively on the front and on the back with a pattern. The thickness of the carrier material then determines the
- FIG. 9 shows an oblique position of the carriers 36, 37 with respect to the propagation direction of the light, ie that the carriers 36, 37 are not exactly at right angles to the propagation direction of the light.
- This embodiment of the invention is dan advantageous when the projector 14 and its optical
- Cameras 32 is aligned.
- the arrangement of the projector 14 in the angled transition region between the receiving area 2, in which the cameras are 32, and the central area 5 is particularly advantageous because in this way the
- Recording area 2 can be kept relatively short, which significantly improves the handling of the handpiece 1. Due to the inclination of the carrier 36, 37 can through the
