Description
Technical Field
The invention relates to the technical field of image scanning, in particular to a chromatic-aberration-free image scanning, displaying and illuminating system.
Background
The information-based era has come, and the traditional manual operation mode is gradually replaced by the information-based application, such as the establishment of a model of a denture and the subsequent manufacturing of the denture, wherein each step needs to be manually completed by a dentist and a professional dental technician, and the clothes are sampled, compared and manufactured subsequently, and the manual work and experience accumulation are also needed, moreover, shoes can be designed in the united states, sampled in asia and then sent back to the united states for confirmation, and the manual work and the confirmation of a physical sample generate the limitation on distance, time and efficiency.
Taking the fabrication of the artificial teeth as an example, the fabrication of the artificial teeth in the prior art is that firstly, a dentist carries out the modeling of a dental model and the artificial color matching of a color card or a toothed plate in a clinic manually, then the dental model is conveyed to a dental skill in a logistics way, and the information of the color card or the toothed plate after color matching is informed to the dental skill; then, carrying out artificial sculpturing and glazing of the false teeth by a dental technician, and then conveying the manufactured false teeth to a dental office in a logistics mode; in the processes, the logistics are repeated to increase the difficulty of remote or transnational operation, the dental model modeling needs manual work, the dental model color matching needs manual work, the artificial tooth sculpturing and the glazing color are needed, and all the manual work of professional technicians is required, so that the mass production is difficult.
If the camera is used to capture images of teeth in the oral cavity, and then the display screen is used to display images, the color matching of the dental model is performed, and the problem of serious chromatic aberration is caused because the spectrum of the ambient light captured by the camera is inconsistent with that of the display screen. In addition, if the material circulation of the dental model or the dental prosthesis is to be avoided, the dental model image can be transmitted to the dental skill, then the display screen is used for representing the image to replace the solid dental model, and then the dental technician carries out sculpturing and glazing according to the tooth information on the display screen, but at the moment, if the ambient light of the dental prosthesis workbench is inconsistent with the display screen displaying the dental model, the spectrum of the ambient light and the spectrum of the display screen displaying the dental model are inconsistent, and the serious chromatic aberration problem is caused again.
Because the fabrication of the artificial tooth, except that the three-dimensional shape of the artificial tooth will affect the occlusion function, whether the color of the artificial tooth is compatible with other healthy teeth in the oral cavity or not is an aesthetic factor which must be considered, if an electronic device is used for image capture, a display screen is used for image generation, and an illumination light source is used for assisting the artificial tooth working platform to process the artificial tooth, if the color difference problem between devices is not overcome, each stage of the fabrication of the artificial tooth has serious color distortion factors, which causes the maximum difficult problems of the artificial tooth to achieve long-distance span, international span, informatization, automation and intelligent production.

As shown in fig. 3A to 3C, the important technical features of the present embodiment are therefore: the image scanner 10, the display screen 20 and the illumination light source 30 respectively have a first light emission spectrum 41, a second light emission spectrum 42 and a third light emission spectrum 43; the first light-emitting spectrum 41, the second light-emitting spectrum 42 and the third light-emitting spectrum 43 are all white lights composed of a plurality of wavelength bands with peak wavelengths, and the first light-emitting spectrum 41, the second light-emitting spectrum 42 and the third light-emitting spectrum 43 all have the same characteristics or the same characteristic curves, so that the image scanner 10, the display screen 20 and the illumination light source 30 can have a common standard spectrum to achieve elimination of chromatic aberration between the devices.
The peak wavelength bands of the first emission spectrum 41, the second emission spectrum 42, or the third emission spectrum 43 may be three-color spectra composed of the same red (R), green (G), and blue (B) color separations.

As shown in fig. 4A and 4B, the image scanner 10 includes: an optoelectronic imaging system 110; a plurality of first light sources 120; and a control module 130. The image scanner 10, which may be a hand-held device, is mainly used to perform oral treatment with a dental prosthesis, so that the manufactured dental prosthesis can match with other healthy teeth in the oral cavity of a patient in terms of color, and thus the image scanner 10 can be used to perform image scanning on the teeth in the oral cavity of the patient and complete 2D or 3D sampling.
The photo imaging system 110 mainly includes a Complementary Metal Oxide Semiconductor (CMOS) or a Charge Coupled Device (CCD) as a photoelectric conversion device. After the optical imaging system 110 performs optical imaging on the teeth in the oral cavity, the optical signal is converted into an electrical signal by the photoelectric conversion element, so as to perform subsequent transmission, image operation and the like; the electrophotographic imaging system 110 may include an imaging optical system for imaging.
As shown in fig. 5, 6A and 6B, the first light source 120 may be a ring-shaped first light source 121, a flat-plate-shaped first light source 122 or a curved-surface-shaped first light source 123. In addition, the first light source 120 can also be designed as a shielding light source 124, which includes: a shield 125; and a plastic element 126.
The shield 125 is in the form of a conventional oxygen mask having an annular wall that is opaque and has a reflective surface 125a on the inside, and a skirt portion of the shield 125 has a mask opening 125b to facilitate covering and covering the periphery of the patient's mouth.
The plastic element 126, which may be an elongated cylindrical body, is formed on the top of the shield 125 and extends into the shield 125, and has a combination through hole 126a, and the plurality of first light sources 120 are formed on the outer surface of the plastic element 126 and project the first light spectrum toward the reflective surface 125a inside the shield 125.
The combination through hole 126a is configured to allow the electrophotographic imaging system 110 to be inserted therein, and when the first light spectrums of the plurality of first light sources 120 are projected on the reflective surface 125a inside the shield 125, the first light spectrums are reflected again and projected on the teeth of the patient, so that the electrophotographic imaging system 110 can take images under the illumination of the first light spectrums.
The first light source 120 is designed to have a first light emission spectrum 41 of white light composed of a plurality of wavelength bands with peak wavelengths, and the first light source 120 is disposed at the periphery of the photoelectric image capturing system 110, and the first light emission spectrum 41 is used as a standard spectrum, so that the photoelectric image capturing system 110 can be supplemented with light, the image scanner 10 can obtain clear images, and standard image capturing images can be established under the standard spectrum.
As shown in fig. 7A and 7B, the control module 130 mainly controls the optoelectronic imaging system 110 to capture a plurality of monochromatic images with different colors according to time-sequence color separation; that is, the control module 130 captures images of only a single color of different colors at different time points in time sequence; for example, monochrome images of red (R), green (G) and blue (B) can be captured in time sequence for the dental prosthesis; or capturing the monochromatic images of red (R), green (G), blue (B) and yellow (Y) according to the time sequence; or capturing monochrome images of red (R), green (G), blue (B), cyan (C), magenta (M) and yellow (Y) in time sequence.
The first light source 120 is composed of a plurality of pixel units (pixels) 130, each pixel unit 140 is composed of a plurality of color separation pixel units (sub-pixels) 150, and each color separation pixel unit 150 is formed by a solid light source 151, a wavelength conversion material 152 such as phosphor or quantum dots, and a color filter 153 for separating the three, four or six colors, so that the first light source 120 can emit and generate a three, four or six color spectrum.
In order to effectively perform monochromatic image capturing according to a time sequence, the control module 130 may illuminate the solid-state light sources 151 of the plurality of first light sources 120 according to a time sequence color separation, that is, only illuminate the solid-state light source 151 corresponding to one color separation color filter 153 at each time, so that the optoelectronic image capturing system 110 may capture a plurality of monochromatic images of different colors according to a time sequence color separation.
Alternatively, a liquid crystal control unit 154 may be further disposed between each color filter 153 and the corresponding solid-state light source 151, at this time, all the solid-state light sources 151 are turned on, but the control module 130 controls the liquid crystal control unit 154 to turn on or off according to the time sequence color separation, so that the optoelectronic image capturing and imaging system 110 can capture a plurality of monochromatic images of different colors according to the time sequence color separation.
The display screen 20 is mainly used to display the dental image obtained by the image scanner 10 on the display screen 20 again, and the patient and the dentist can make communication and adjustment on the color, brightness, etc. of the dental prosthesis before the dental prosthesis is manufactured by the display screen 20.
In order to avoid the device color difference between the image displayed on the display screen 20 and the image captured by the image scanner 10, the light emission of the display screen 20 is very important, and therefore the display screen 20 of the present embodiment is designed to have the second light emission spectrum 42 when the image is displayed on the display screen 20.
The second light-emitting spectrum 42 is also the second light-emitting spectrum 42 of the white light composed of a plurality of wavelength bands with peak wavelengths, and the second light-emitting spectrum 42 and the first light-emitting spectrum 41 have the same characteristics, so that the problem of device color difference between the display screen 20 and the image scanner 10 can be solved under the same standard spectrum condition.
When a dental technician intends to make a dental prosthesis, the illumination light source 30 must first grasp an image of a tooth in the oral cavity of a patient as a template before the dental prosthesis can be made, and a place where the dental technician makes the dental prosthesis and a dental office of a dentist are not located at the same place.
In the case where the patient cannot be seen face-to-face or in person, the dental technician can present the image obtained by the image scanner 10 at the dental technician's site on the display screen 20 of the dental institute 300 as a template for creating a dental prosthesis, and the display screen 20 of the dental institute 300 is identical to the display screen 20 at the dental technician's site and has the same second light emission spectrum 42.
When manufacturing a denture, it is usually necessary to copy the dental image template presented by the display screen 20 and to manufacture the denture on the denture work platform; if there is a device color difference between the display screen 20 and the illumination light source 30 of the dental prosthesis working platform, the dental technician will misjudge the color, and thus the color of the dental prosthesis will be distorted.
Therefore, the lighting source 30 of the dental prosthesis working platform is designed such that the lighting source 30 has the third light emitting spectrum 43, the third light emitting spectrum 43 is also the third light emitting spectrum 43 of white light composed of a plurality of wavelength bands of peak wavelengths, and the third light emitting spectrum 43 and the second light emitting spectrum 42 have the same characteristics, so that the problem of device color difference between the display screen 20 and the lighting source 30 can be solved under the same standard spectrum condition.
While the foregoing embodiments have been described in a specific embodiment, the present invention is not limited to the specific embodiments, but rather to the specific embodiments, which are disclosed and illustrated herein, it will be appreciated by those skilled in the art that various modifications and variations may be made without departing from the spirit of the invention.
