Abstract
Description
The present invention relates to an oral scanner for dental use, and more particularly, to an oral scanner capable of acquiring accurate three-dimensional image data by photographing an object to be imaged at different viewing angles through two or more optical paths.
The oral scanner is a device for acquiring a three-dimensional image in the oral cavity of a dentist or the like. In accordance with a three-dimensional image acquisition method, there is a confocal method, optical coherence tomography, stereo vision method, and triangulation method.
Since the oral scanner must be inserted into the oral cavity, the size miniaturization technique is very important.
Hereinafter, an example of a conventional oral scanner will be described with reference to FIG.
1, a conventional oral scanner has an optical path in which light emitted from a
However, in the case of the above-described conventional oral scanner, a single light beam is irradiated in the same direction with respect to the target through the
SUMMARY OF THE INVENTION It is an object of the present invention to provide an oral scanner capable of acquiring accurate three-dimensional image data by photographing an object to be imaged at two or more viewing angles by forming two or more optical paths in the oral scanner .
According to an aspect of the present invention, there is provided an image pickup apparatus including at least two light sources, a same number of optical systems corresponding one-to-one with the light sources, a same number of image pickup elements corresponding one- Wherein the light emitted from each of the light sources includes a plurality of light paths each having an optical path corresponding to each of the corresponding optical systems, one point of an object to be imaged, each corresponding optical system, Scanner.
The projector may further include a plurality of projectors for irradiating light emitted from each of the light sources to the respective optical systems. Preferably, each of the projectors converts the light emitted from each of the light sources into pattern light.
The optical path may have a plurality of optical paths reflected at a point of the object to be imaged, and the housing may be provided with a lens that focuses on one point of the object to be imaged between each of the projectors and each of the optical systems .
A first optical fiber which connects the respective light sources and the respective optical systems and a second optical fiber which connects the optical systems and the respective imaging elements to each other. At this time, the housing may be formed with a corrugated portion that surrounds the plurality of first optical fibers and the plurality of second optical fibers.
And a processing unit for digitizing the images photographed by the plurality of image pickup devices.
And a wireless communication unit for wirelessly transmitting data of the processing unit to the outside.
According to the present invention described above, it is possible to take an image of an object to be imaged through two or more light paths, and capture an image of the object with two or more viewing angles.
Further, according to the present invention, two or more optical paths can be flexibly implemented using optical fibers, and the size of the oral scanner can be reduced.
In addition, according to the present invention, since three-dimensional image analysis is easily performed when photographing is performed with a plurality of viewing angles, the processing time of three-dimensional data can be saved.
FIG. 1 is a schematic diagram showing a process of acquiring a three-dimensional image by a conventional oral scanner,
2 is a schematic diagram schematically showing an embodiment of an oral scanner having a plurality of lenses according to the present invention,
3 is a schematic view schematically showing another embodiment of an oral scanner having a plurality of lenses according to the present invention, and Fig.
4 is a view showing an example of a housing to which the embodiment of FIG. 3 is applied.
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. The shape and the size of the elements in the drawings may be exaggerated for clarity and the same elements are denoted by the same reference numerals in the drawings.
And throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between. Also, when a component is referred to as being "comprising" or "comprising", it is to be understood that this does not exclude other components, unless the context otherwise requires, do.
