[0003] The tongue surface collector can collect the user's tongue surface image and facial image for subsequent diagnosis and treatment analysis. The higher the color restoration of the patient's facial image, the more accurate the diagnosis. Therefore, in order to improve the image quality, it is inevitable to use high-brightness and high-color rendering index LED lights for fill light. However, during the fill light process, the LED light is strong, which will cause a "dazzling" feeling to the user and make the user feel uncomfortable. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] First, as Figures 1 to 3 As shown, the embodiment of the present application provides an image acquisition device for medical consultation, including a shell 1, which is provided with a chamber for accommodating the user's face; also including a camera system 2, which is fixed in the shell 1 and can determine the position of the user's eyes; also including a light source 3, which is used to emit light to fill in the user's face, so that the tongue surface image and facial image of the user are acquired clearer; also including a shading system, including a shading member 4, which is located above the light source 3; the shading member 4 is provided with an opaque area 41 corresponding to the position of the eyes, and the opaque area 41 can block light; in this way, when the light emitted by the light source 3 passes through the shading member 4, the opaque area 41 It plays the role of blocking light, so that the light irradiated to the user's face at the position of the eyes is shielded, reducing the user's glare and improving the user's comfort during tongue and face examination; and the other facial areas except the position of the eyes are illuminated, thereby playing the effect of fill light, improving the clarity of the acquired user's facial image and tongue and face images. After the fill light, the camera system 2 is also used to collect the user's facial images and tongue and face images of other areas except the blocked areas of the eyes after the fill light, so that clearer facial images and tongue and face images can be collected, which is convenient for the subsequent analysis of the user's facial images and tongue and face images, making the analysis results more accurate, and playing the role of assisting medical staff in diagnosis.

[0032] Optionally, the medical consultation image includes a facial image and a tongue image of the user; of course, it may also include images of other limbs, such as an image of the palm, and the like.

[0033] Optionally, the image acquisition device for medical consultation may also include a facial image processing system, which can analyze the user's facial information to assist medical staff in medical consultation; of course, the facial image processing system can also upload the user's facial image to the cloud for analysis and processing by the cloud.

[0034] like Figure 3 As shown, optionally, the opaque area 41 can be a rectangle to shield the light from shining on both eyes; it can also be two spaced squares; each square shields the light from shining on the eyes; of course, it can also be two circles; of course, the opaque area 41 can also be a ring-shaped ring, and the corresponding number of rings can be opened according to different ages, genders, and pupil distances.

[0035] Optionally, the opaque area 41 blocking light may absorb the light from the light source 3, that is, the shading member 4 may be transparent and can transmit light when no power is supplied, such as a transparent liquid crystal panel; the transparent liquid crystal panel may locally generate a black area, namely the opaque area 41, and the black area can absorb light, while other areas can transmit light; or the transparent liquid crystal panel may completely generate black areas, thereby reducing the amount of light irradiating the user's eyes; the opaque area 41 blocking light may also completely shield the light from the light source 3, that is, the shading member 4 itself is opaque, such as an opaque liquid crystal panel, and may locally generate a black area, namely the opaque area 41. Since black light is not dazzling, the generated black area can reduce the glare to the user, and other areas of the liquid crystal panel except the black area can generate white light to achieve a fill light effect on the user's face; of course, the opaque liquid crystal panel may also display all black.

[0036] Optionally, the image of the opaque area 41 projected onto the lens 8 will be magnified so as to completely cover the positions of the user's eyes, and the proportional relationship between the area of ​​the opaque area 41 and the area of ​​the coverage area generated by projecting onto the user's eyes can be pre-calculated.

[0037] Optionally, the position of the user's eyes can be determined by the camera system 2 or the image processing unit 5, that is, the camera system 2 can include a camera 21 and an image processing unit 5, the camera 21 captures the user's facial image, and the image processing unit 5 can analyze the position of the user's eyes; of course, the camera system 2 can also include only the camera 21, and the image acquisition device for medical consultation includes the image processing unit 5, the camera 21 is used to obtain the user's facial image, and the image processing unit 5 on the shell 1 is used to analyze the image to obtain the position of the eyes.

[0038] Optionally, the light source 3 may be a projection light source.

[0039] Optionally, determining the position of the user's eyes also includes determining the size between the user's eyes. If the opaque area 41 is two areas that respectively block the user's eyes, the distance between the two opaque areas 41 can be adjusted according to the size between the eyes.

[0040] Optionally, after fill light, the tongue surface image captured by the camera system 2 includes at least two images, namely the front and back of the tongue. Of course, more images can also be captured; the camera system 2 captures at least one facial image.

[0041] Optionally, the image acquisition device for medical consultation in the embodiment of the present application may also acquire and analyze the palm of the user, and of course, may also acquire and analyze other parts of the body.

[0042] like Figure 1 and2 As shown, as an embodiment, the shading member 4 includes a display panel, and the shading system also includes a panel controller 6 and a panel driver 7. The display panel is horizontally arranged above the light source 3, so that the light source 3 can be irradiated onto the display panel. The panel controller 6 and the panel driver 7 both interact with the display panel signal. In this way, after the panel controller 6 receives the position information of the user's eyes, it controls the panel driver 7, and the panel driver 7 causes the display panel to form an opaque area 41 corresponding to the position of the eyes, thereby blocking the light irradiated to the user's eyes and reducing the glare problem.

[0043] Optionally, the signal interaction is performed through an electrical connection, and the interactive signal is, for example, an electrical signal.

[0044] like Figure 1 As shown, optionally, the panel controller 6 and the panel driver 7 are both fixed on the housing 1 .

[0045] like Figure 1 As shown, optionally, the image processing unit 5 is also fixed on the housing 1 and interacts with the camera 21 and the panel controller 6 respectively in signal communication.

[0046] Optionally, the display panel may change the opaque area 41 in real time according to the position of both eyes, that is, when the user's head moves, the opaque area 41 also changes accordingly, thereby realizing the function of dynamically changing the occlusion area.

[0047] Optionally, the display panel can be a liquid crystal panel or an OLED (Organic Light-Emitting Diode, organic electric laser display) panel. If it is a liquid crystal panel, it includes a liquid crystal layer, a transparent conductive layer, a polarizer and other parts. When there is no electric field, the liquid crystal molecules are in a twisted state, and the liquid crystal layer cannot transmit light. After the light source 3 passes through the liquid crystal layer, polarized light will be generated, causing the light to be unable to pass through the polarizer, thereby appearing black, and black can absorb light, and, in the absence of an electric field, the light from the light source 3 cannot pass through the liquid crystal panel, thereby forming an opaque area 41. Therefore, when the light source 3 irradiates the liquid crystal panel, the liquid crystal panel can block the light source 3, and the blocked light source 3 can avoid directly irradiating the user's eyes, thereby improving the user's comfort; and the light not blocked by the liquid crystal panel can irradiate the user's face, achieving the effect of fill light.

[0048] In addition, when a liquid crystal panel is used, the traditional backlight layer can be eliminated and can be directly replaced by the light source 3 on the housing 1, thereby reducing the production cost; of course, a backlight layer can also be added.

[0049] Optionally, the regional light control technology can be used to make the liquid crystal panel partially black, that is, to locally generate an opaque area 41, so that the panel controller 6 can determine the area size of the black display area of ​​the liquid crystal panel through the panel driver 7 according to the position of the user's eyes and the distance between the two eyes. In addition, the panel controller 6 can also control the panel driver 7 to enable the liquid crystal panel to change the size of the black display area in real time, so as to monitor the position of the user's eyes in real time.

[0050] Optionally, the camera system 2 can capture the user's face in real time, and determine the position of the user's eyes and the distance between the eyes in real time through the image processing unit 5; the panel controller 6 can control the panel driver 7 to adjust the size of the opaque area 41 of the display panel in real time according to the user's face captured in real time by the camera system 2.

[0051] Optionally, the display panel can also be an OLED panel, which includes multiple pixels, each of which can emit light independently. When the pixels are turned off, the OLED panel forms an opaque area 41, which is used to block all light, or turns off some pixels to partially block light.

[0052] Optionally, the panel controller 6 may control the panel driver 7 to turn off pixels of the OLED panel.

[0053] like Figure 2 As shown, as an embodiment, a lens 8 is provided on the bottom wall of the chamber, and the lens 8 is arranged toward the user's face. The light at the position of the eyes blocked by the shading member 4 cannot be irradiated to the eyes of the user, and the light in other areas can be irradiated to the user's face through the lens 8. At the same time, the lens 8 generally has a focusing structure. Therefore, during the focusing process, the size of the fill light area and the area of ​​the opaque area 41 can also be adjusted.

[0054] like Figure 1 and 2 As shown, as an embodiment, a first lens 9 is further provided above the light source 3, and the first lens 9 is located between the light source 3 and the shading member 4. The first lens 9 can make the light source be installed in a specified direction and stroke to emit toward the shading member 4. The first lens 9 is also used to collect the light from the light source 3, so that the light is more evenly irradiated on the shading member 4, so as to better fill in the light and improve the final analysis results of the facial image and the tongue surface image; at the same time, the opaque area 41 on the shading member 4 can also form a sharp contrast with the light passing through, so as to improve the anti-glare effect.

[0055] like Figure 1 and 2 As shown, as an implementation mode, a focusing bowl 11 is provided below the light source 3, and the focusing bowl 11 is used to narrow the light-emitting angle of the light source 3, thereby improving the brightness of the light source 3 and reducing the power of the light source 3.

[0056] like Figure 1 and 2 As shown, the image acquisition device for medical consultation also includes a reflector 12, which is tilted and located above the shading member 4. It can change the propagation path of light and reflect the light and the opaque area 41 onto the lens 8, and irradiate the user's face through the lens 8, thereby achieving the effect of reducing light glare in the image acquisition device for medical consultation.

[0057] Optionally, the reflector 12 may be fixed on the housing 1 ; or connected via a frame inside the housing 1 .

[0058] like Figure 2 As shown, optionally, a frame can be provided in the housing 1, and parts such as the light source 3, the focusing bowl 11, and the shading member 4 can be fixed on the frame.

[0059] like Figure 1 and 2 As shown, optionally, a second lens 10 can be further arranged between the reflector 12 and the shading member 4. The second lens 10 can cause the light source and the opaque area 41 to be emitted toward the reflector 12 in a specified direction; at the same time, the light passing through the shading member 4 can also be further converged to increase the brightness of the light, thereby further making the facial image and tongue surface image acquired by the camera 21 clearer, facilitating subsequent analysis and making the analysis results more accurate.

[0060] like Figure 1 and 2 As shown, as an embodiment, the camera system 2 includes a camera 21 connected to the shell 1, and the camera 21 is used to obtain the user image; the image acquisition device for medical consultation also includes an image processing unit 5 connected to the shell 1, and the image processing unit 5 is used to analyze the user image and determine the position of the user's eyes, so that the shading member 4 can generate an opaque area 41 corresponding to the position of the eyes.

[0061] Optionally, the camera 21 can obtain a facial image of the user and analyze the positions of the user's eyes through the image processing unit 5 .

[0062] Optionally, after fill light, the camera 21 can be tilted slightly downward so that the camera 21 only captures images below the eyes.

[0063] like Figure 1As shown, as an embodiment, the image acquisition device for medical consultation also includes a tongue and face diagnosis processing system 13. The tongue and face diagnosis processing system 13 interacts with the camera system 2 in signals. The tongue and face diagnosis processing system 13 can obtain the user's tongue and face images taken by the camera system 2 and analyze the tongue and face information, so as to assist medical staff in medical consultation; of course, the tongue and face diagnosis processing system 13 can also transmit the user's tongue and face images taken by the camera system 2 to the cloud server, which will be analyzed by the cloud server to assist medical staff in medical consultation.

[0064] like Figure 2 As shown, as an embodiment, the camera system includes a camera 21 connected to the shell 1, and the camera 21 is used to obtain the user image in real time after the light source 3 is started; the image acquisition device for medical consultation includes an image processing unit 5, and the image processing unit 5 is used to analyze the obtained user image in real time and determine the position of the user's eyes. The user image is obtained in real time by the camera 21, and the image processing unit 5 determines the position of the user's eyes in real time, so that the shading system can adjust the area of ​​the opaque region 41 in real time according to the real-time determined position of the user's eyes, so that the shading member 4 can dynamically generate the opaque region 41 to block the light irradiated to the eyes.

[0065] Optionally, acquiring the user image in real time may be acquiring the user's facial image in real time.

[0066] Optionally, since the camera system 2 will capture multiple tongue surface images, such as the front and back, the user's head will move during the capture process, and the position of the eyes will also move. Therefore, by determining the position of the user's eyes in real time, the shading member 4 can dynamically generate an opaque area 41.

[0067] like Figure 2 As shown, optionally, a heat sink 14 is further provided in the housing 1 to dissipate heat for parts in the housing 1 .

[0068] As an implementation mode, before the shading system is started, the camera system 2 first obtains an image of the user, which may be a facial image of the user, to determine the position of the user's eyes.

[0069] When using the image acquisition device for medical consultation, the user can place the face in the cavity of the shell 1 and take an image through the camera 21. At this time, the shading system and the light source 3 are not started; the image processing unit 5 obtains the user's facial image and analyzes the position of the user's eyes. The panel controller 6 receives the user's eye position information and controls the control panel driver 7 to control the shading member 4 to generate an opaque area 41 corresponding to the user's eye position. At this time, the light source 3 is started, and the light emitted by the light source 3 is increased in brightness through the focusing bowl 11, and the light is collected through the first lens 9 to make the light irradiated on the shading member 4 more uniform. The opaque area 41 on the shading member 4 can absorb or block the light, and the light in other areas can pass through the shading member 4. The light or the light emitted by the shading member 4 (such as using an opaque liquid crystal panel or an O liquid crystal panel) is irradiated onto the reflector 12 through the second lens 10, and the reflector 12 reflects the light and the opaque area 41 to the lens 8, and then irradiates the user's face through the lens 8 for fill light. At this time, the user's eyes will be blocked or absorbed by the opaque area 41 of the shading member 4, so that the light cannot be irradiated to the user's eyes, thereby reducing the user's glare. After fill light on the face, the camera 21 can collect facial images and tongue images again, and the tongue and face diagnosis processing system 13 and the facial image processing system can analyze the user's tongue and facial information, or the cloud can analyze the user's tongue and face to assist medical staff in conducting consultations.

[0070] Optionally, if the opaque area 41 is discontinuous, that is, two discontinuous opaque areas 41 are generated, the panel driver 7 can directly cause the display panel to generate corresponding opaque areas 41 according to the information of the position of the user's eyes; if the opaque area 41 is a complete rectangle, the panel driver 7 can cause the display panel to generate corresponding opaque areas 41 according to the information of the position of the user's eyes.

[0071] Based on the image acquisition device for medical consultation of any of the above embodiments, a second aspect of the embodiments of the present application further provides an image acquisition method for medical consultation, which includes steps S1 to S3.

[0072] Step S1: Acquire the user image captured in real time by the camera system 2;

[0073] Step S2: determining the opaque area 41 of the shading member 4; wherein the position of the opaque area 41 in the shading member 4 is related to the image position of the eye area of ​​the user in the user image; the opaque area 41 is used to block light, so that the light emitted by the light source 3 passes through the shading member 4 and irradiates other areas of the user's face except the eye area;

[0074] Step S3: Control the camera system 2 to collect the user's medical consultation images.

[0075] The above method may be executed by a control device of the shading member 4. For example, if the shading member 4 includes a display panel, and the display panel interacts with the panel controller 6 and the panel driver 7, the above method may be executed by the panel controller 7.

[0076] Exemplarily, the user image is used to determine the opaque area 41 of the shading member 4. For example, the image content of the user image includes the eye area of ​​the user. The image position of the eye area in the user image is related to the position of the opaque area 41 in the shading member 4. The so-called correlation means that the position of the opaque area 41 in the shading member 4 changes as the image position of the eye area changes. Specifically, the eye area can be identified from the user image, and the image position of the eye area in the user image can be determined, and then the position of the opaque area 41 in the shading member 4 is set accordingly. Among them, the mapping relationship between the image position of the eye area and the position of the opaque area 41 in the shading member 4 can be pre-calibrated, and this application will not expand on this. And, the specific setting method of the opaque area 41 can refer to the above embodiment.

[0077] The consultation image is used to obtain the diagnosis and treatment information of the user. For example, the consultation image may include but is not limited to the user's facial image, tongue image, etc. The tongue image, for example, includes but is not limited to the front and back images of the tongue. Optionally, the user image and the consultation image may be the same image. Optionally, the user image and the consultation image may be different images. For example, the user image is first captured to adjust the position of the opaque area 41 of the shading member 4 so that the shading member 4 blocks the light in the user's eye area. Then the user's consultation image is captured.

[0078] As an example, after obtaining the real-time collected user image, if the light source 3 is not turned on, the light source 3 can be kept turned off first, and after the position of the opaque area 41 is determined and the opaque area 41 is controlled to reach an opaque state, the light source 3 is turned on and the consultation image is collected. This situation is often applicable to when the user first starts using the consultation image acquisition device.

[0079] In addition, during the process of collecting medical consultation images, actions such as shaking the head or shaking the head will cause the position of the user's head in the chamber to change. In order to make the position of the opaque area 41 adapt to the change of the user's head position, in one example, the camera system 2 can periodically collect user images, so that when the user's head position changes, the position of the opaque area 41 can be adjusted in time to ensure the shading effect of the eye area.
