[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the embodiments of the present invention.

[0056] When taking care of teeth, there are many types of tooth lesions, including deformity, color change, wear, etc. The development progress of various lesions is different, and the inner side of the teeth is not easy to observe. Even if dental care and medical examinations are performed several times a year, it is impossible to find various adverse changes in various parts of the teeth early, resulting in the user (or patient) being unable to take timely and accurate care of their teeth. Although the prior art uses a camera to shoot the user's teeth, the shooting mode is single. For complex tooth lesion characteristics, it is impossible to obtain the change in the health status of the teeth through simple image comparison, so that the user cannot find tooth damage in time. The following embodiments of the present invention will specifically explain how to take timely and accurate care of the user's teeth.

[0057] See also Figure 1 , Figure 1A data transmission diagram of a dental care system provided in an embodiment of the present invention, wherein the dental care system comprises a medical data platform 1 and at least one collection terminal 2. The number of collection terminals 2 can be configured based on actual needs. For example, corresponding configurations can be made for users with dental care needs so that each user is equipped with a corresponding collection terminal. One or more collection terminals can also be configured based on a single family.

[0058] Each acquisition terminal is used to perform image acquisition tasks for the corresponding terminal user at different health care periods. The image acquisition task is to shoot the terminal user's teeth at multiple angles in different color shooting modes through the acquisition terminal and send it to the outside. The health care period can be freely set based on the terminal user's time. For example, for a terminal user with poor dental health, it can be set to take images of their teeth every half a month, and for a terminal user with good dental health, it can be set to take images of their teeth every one or two months.

[0059] Color shooting modes include cold-tone shooting mode, black-and-white shooting mode, high-definition color mode, enhanced contrast mode, ultraviolet light mode, infrared light mode, etc. The terminal user can obtain diversified image features in different color shooting modes. The tooth images taken from multiple angles can more comprehensively reflect the tooth changes of the terminal user and can be sent to the medical data platform via the Internet. The medical data platform is used to receive the tooth images taken from multiple angles in different color shooting modes for each terminal user, as well as the comparison results of the tooth images in the same color shooting mode in different image acquisition tasks, and output the corresponding terminal user's dental care results.

[0060] The acquisition terminal can be configured as a portable structure, for example, a rod-shaped result including a handle. The portable structure is convenient for the terminal user to carry and implement multi-angle shooting operations of teeth. Different shooting angles are used to shoot the outer side of the teeth, the inner side of the teeth and the occlusal surface of the teeth. By shooting at multiple angles, the actual health status of the teeth can be determined in all directions and the pathological characteristics of the teeth can be discovered in time. Multiple tooth images can be taken at each shooting angle, or a panoramic image can be taken at each shooting angle based on the operation of the terminal user. When shooting the outer side of the teeth, the terminal user's teeth can be exposed as a whole through a mouth opener to obtain a complete outer side image of the teeth, that is, a panoramic image of the outer side of the teeth. The medical data platform can be a cloud platform or a data storage platform built by a local server. After each terminal user's tooth images in different image acquisition tasks are uploaded to the medical data platform, the tooth images of each terminal user are stored accordingly. Corresponding user tags can be established for different terminal users, and dentists can log in to the medical data platform to identify the corresponding terminal users based on the user tags. Dentists can compare and view tooth images of the same color shooting mode in different image acquisition tasks through local devices (such as PC devices, Personal Computers) to determine whether each tooth has a lesion. It can be understood that since dentists do not diagnose dental lesions based on a single tooth image, but rather by comparing tooth images in various color shooting modes in adjacent or multiple image acquisition tasks, the lesion characteristics represented by the teeth are easier to identify in different color shooting modes, thereby improving the accuracy of dental lesion diagnosis.

[0061] It should be noted that the technical solution adopted in the embodiment of the present invention enables each terminal user to be equipped with a corresponding acquisition terminal, which can help the terminal user to regularly learn about the changes and health status of their own teeth, obtain continuous dynamic data on dental health, and make dental care more timely. In different color shooting modes, the image features obtained by comparison are richer, and it is easier to compare the changing features of teeth under different image acquisition tasks. The terminal user or dentist can detect dental lesions in time, making dental care more accurate, and then take corresponding treatment measures.

[0062] After the dentist determines that the terminal user has a tooth lesion, he or she can contact the terminal user by phone to inform him or her, or he or she can write a relevant diagnosis and treatment report and send it to the terminal user's mobile terminal, collection terminal, etc., so as to inform the terminal user of the tooth lesion. There is no specific restriction on the type of terminal device that receives the diagnosis and treatment report.

[0063] The color shooting mode in the image acquisition task can be set to a fixed multiple shooting modes, such as cold tone shooting, color tone shooting, black and white shooting, that is, more image contrast features can be extracted directly through different color shooting modes.

[0064] Of course, the corresponding color shooting mode can also be determined based on the health care items of different terminal users' teeth, that is, the corresponding dental lesions are photographed in different color shooting modes. For example, based on different health care items and corresponding shooting modes, a mode correspondence relationship is obtained. When performing an image acquisition task, an applicable shooting mode is determined based on the current health care item in the mode correspondence relationship. For example, for health care items with fine cracks and uneven changes in teeth, a black and white shooting mode is selected to obtain black and white photos of teeth for the health care item. By comparing the black and white photos of teeth for different image acquisition tasks, the changes in fine cracks and unevenness of teeth can be more accurately obtained. For the color change of teeth, a color shooting mode can be used. After image comparison, the characteristics of the change of the color of the terminal user's teeth over time can be accurately obtained. For health care inspections of plaque and stains, cold tones can be used for shooting. When observing the color change of teeth or small cracks on the surface of teeth, cold tones can provide more image details. Cold tones usually make the white part appear brighter, and make warm-colored tooth problems (such as yellow spots and plaque) more prominent. This can help terminal users or dentists quickly distinguish abnormal lesions on the surface of teeth.

[0065] In order to ensure the accuracy of image comparison for different health care items, in the embodiment of the present invention, a high-definition color mode, an enhanced contrast mode, an ultraviolet light mode, an infrared light mode and a filter mode are also provided. It can clearly display the overall shape, color, surface texture of the teeth and the contrast between the teeth and the surrounding gums, which is convenient for observing the shape, arrangement and gum health of the teeth, and is suitable for routine examinations. In the enhanced contrast mode, the captured tooth image can help highlight the surface details of the teeth, especially in the case of bacterial aggregation, plaque accumulation or early tooth decay, providing a clearer contrast. In the ultraviolet light mode, the active light source is controlled to emit ultraviolet rays, and the photo is taken after ultraviolet irradiation, which can be used to detect the fluorescent reaction of certain bacteria on the tooth surface, helping to find problems such as plaque or tooth decay. Under infrared light, the heat and blood flow changes of the gums can show potential periodontal inflammation or deep lesions, show the thermal distribution of teeth and gums, and help dentists find inflammation after image comparison. The filter mode can be used to emphasize a specific color range. For example, using a yellow filter can reduce the reflection of blue light and make the yellow spots on the teeth more prominent. On the contrary, a blue filter can highlight the white part of the teeth, thereby helping to diagnose changes in deposited pigments on the teeth. Through this implementation strategy, the accuracy of the end-user's dental care results can be effectively improved.

[0066] For example, see Figure 2-1 , Figure 2-1The main structure diagram of the acquisition terminal. The acquisition terminal includes a camera 21, an active light source 22 and a controller. The acquisition terminal is a rod-shaped structure as a whole. The tail of the acquisition terminal is a handle 24, which is convenient for the terminal user to hold when photographing his teeth. The handle is a hollow structure inside, and a controller, battery, circuit board, etc. can be installed. Buttons and indicator lights can also be set on the handle 24. The buttons and indicator lights are connected to the controller. The terminal user triggers the button to perform the image acquisition task (i.e., take a photo). The camera 21 is installed on the external shell of the acquisition terminal. The external shell is round or oval, which is convenient for placement in the mouth of the terminal user. The camera is used to take pictures of the terminal user's teeth based on different color shooting modes when performing image acquisition tasks and output them to the outside. The resolution of the camera can be selected based on actual needs, and it is sufficient to be able to clearly capture the pathological characteristics of the teeth. In order to enable the acquisition terminal to shoot the inner side and occlusal surface of the teeth, the embodiment of the present invention sets a bending section 25 in the middle of the acquisition terminal. The bending section 25 can be set as a hollow bellows structure, which can be bent to different angles by the terminal user. After the bending section 25 is bent, the handle 24 and the plane where the camera 21 is located are at a preset angle, and the inner side of the teeth can be photographed; after the bending section 25 is straightened, the handle 24 is parallel to the plane where the camera 21 is located, and the occlusal surface of the teeth can be photographed. The bending section 25 can also be set as a segmented bending structure, and each segment corresponds to a bending angle. Please refer to Figure 2-2 , Figure 2-2 This is a schematic diagram of the side view structure of the acquisition terminal. After the bending section 25 is bent, the camera 21 can shoot the inner side of the tooth in a positive direction, thereby improving the shooting quality of the tooth image.

[0067] The active light source 22 is arranged on the periphery of the camera 21, and a D65 light source can be selected. The active light source is used to provide the same lighting environment when the camera performs different image acquisition tasks. The same lighting environment includes shooting teeth at the same brightness, and can also be shot at the same color temperature and illumination. As shown in the figure, the active light source of the embodiment of the present invention includes 8 lamp beads, which are arranged in a circular array on the periphery of the camera. This structure can make the active light source emit a spectrum uniformly and continuously to the surroundings, and the illumination is stable, thereby improving the shooting quality of the tooth image and reducing the image difference caused by the lighting environment for different image acquisition tasks. The active light source can also use a multi-color light source, such as an RGB (Red Green Blue) light source. The multi-color light source is used to provide applicable lighting tones in the corresponding color shooting mode, that is, the active light source emits light of corresponding color temperature in different color shooting modes. Light sources of different colors can adapt to the corresponding color shooting mode, enhance the color contrast of teeth, and highlight specific dental problems, such as dental plaque, pigmentation, caries and gum health. The use of a multi-color light source can help improve the accuracy and comprehensiveness of diagnosis, making dental problems easier to be discovered and evaluated.

[0068] Please continue reading Figure 2-2 , since the camera is in a close-up state when shooting teeth, glare may occur due to the fill light of the active light source, in order to further improve the shooting quality of the tooth image. In the embodiment of the present invention, the periphery of the camera is set as a recessed structure, lamp beads are arranged around the camera, and the peripheral structure is designed to be recessed inward, and a metal plate with a convex structure is laid on the recessed surface to form a concave reflective surface 26. The quality of the camera when shooting at a close distance is improved through this combined design. Of course, a lampshade can also be arranged to be installed on the lamp beads, so that the fill light of the lamp beads for shooting is softer, thereby improving the quality of close-up shooting. It can be understood that the recessed structure can help control the reflection path of the light, guide part of the light emitted by the lamp beads to the photographed teeth, and reduce the glare or shadow caused by strong direct light by focusing and evenly distributing the light.

[0069] The controller can be a control board equipped with a single-chip microcomputer or a control board integrated with an embedded system, which can implement control and data transmission. The controller is connected to the camera, and the controller is used to configure different color shooting modes for the camera based on the health care items of the terminal user, and to receive the tooth images taken by the camera and send them to the medical data platform. It should be noted that the various components in the acquisition terminal can be powered by an internal battery or an external power supply, as long as the normal operation of the acquisition terminal can be guaranteed.

[0070] In actual applications, although different image acquisition tasks can have the same illumination through the illumination of active light sources, they will still be affected by the external lighting environment when the image is captured. Based on this, in a specific embodiment, the acquisition terminal also includes a light source sensor 23. The light source sensor 23 is connected to the controller, and the light source sensor is used to obtain the ambient brightness when the image acquisition task is executed, and output it to the controller; the controller is also used to output an enable signal for executing the image acquisition task when the ambient brightness is less than a preset brightness threshold. Of course, the color temperature of the image acquisition task during execution can also be determined by the light source sensor 23. In the same color shooting mode of different image acquisition tasks, the color temperature of the tooth image shooting should be the same, or the difference should be less than the preset value.

[0071] A light source sensor is a device that can detect changes in light intensity and convert light signals into electrical signals. The light source sensor can be used to determine the brightness of the environment in which the terminal user is performing an image acquisition task through the acquisition terminal. When the ambient brightness is greater than or equal to the brightness threshold, it means that the ambient light is strong, which may affect the shooting quality, and the enable signal is stopped from being output, and the image acquisition task cannot be performed normally; on the contrary, when the ambient brightness is less than the brightness threshold, it means that the environment is dark, and shooting is only carried out through active light source fill light. The captured dental image is less affected by the light of the external environment, which can ensure that the external lighting conditions of the acquisition terminal are similar each time it is used, reducing the impact of external lighting conditions on the acquired image. Similarly, when there is a difference in color temperature, the color temperature of the active light source can be adjusted through the controller until the color temperature of the same color shooting mode is the same under different image acquisition tasks. Through brightness and color temperature detection, the end user needs to use the acquisition terminal under specific conditions. For example, each image acquisition task is performed in a dark room with no lights, or in a lightless environment at night. The light source of the captured image comes entirely from the device's own active light source, thereby ensuring that the lighting conditions are consistent each time the image acquisition task is performed, reducing the impact of changes in lighting conditions on the images obtained by multiple captures.

[0072] In actual applications, since the acquisition terminals are mostly prepared with the same appearance structure, it is easy to cause confusion when multiple terminal users use them in the same scene. For example, when there are multiple terminal users in a family, the terminal users and the acquisition terminals are confused, resulting in the captured dental images not corresponding to the terminal users. Based on this, in a specific implementation, the acquisition terminal also includes an interactive component.

[0073] The interactive component is connected to the controller, and the interactive component is used to input the terminal serial number to implement the identity binding of the corresponding terminal user. The interactive component can be an input and output component composed of a numeric keyboard and an LCD screen, or it can be a communication component connected to the terminal user's mobile phone. For example, the controller communicates with the mobile phone through the interactive component, and the controller is controlled by the mobile phone to complete the identity identification and binding operation of the corresponding terminal user. Of course, the interactive component can also be set as a fingerprint sensor, and the terminal user is identified and bound through the fingerprint sensor. The image acquisition task can only be executed when the terminal user passes the identity verification through the fingerprint sensor; otherwise, the identity verification failure prompt is given through the indicator light and other components set on the acquisition terminal. Each acquisition terminal is bound to an identity through the interactive component, which can prevent the terminal user's acquisition terminal from being confused and further improve the accuracy of dental image acquisition. It should be noted that for home users, the interactive component can also be used to identify the terminal users in the family separately to ensure that the collected dental images are collected to the corresponding terminal users.

[0074] When the camera takes pictures of the end user's teeth, it needs to be done by hand. If there is a difference or shaking in the shooting positions held by different image acquisition tasks, it will also cause inaccurate tooth image acquisition and comparison. Based on this, in a specific implementation, the dental care system of the embodiment of the present invention also includes a fixing frame 3.

[0075] The fixing frame 3 is matched with the acquisition terminal 2, that is, each acquisition terminal is equipped with a corresponding fixing frame, which is used to clamp or support the head of the terminal user, and to position it at the corresponding shooting position when the acquisition terminal shoots at different angles. The fixing frame can be set as a head-mounted type, which makes it more convenient; it can also be set as a floor-standing support structure, which makes the fixing frame have better stability; it can also be set as a frame structure that clamps the face of the terminal user, which can support or clamp the head of the terminal user. Positioning structures for shooting at different angles are set on the fixing frame, and shooting at corresponding angles is implemented after each positioning structure fixes the acquisition terminal.

[0076] The fixed frame can ensure that when different image acquisition tasks are executed, the relative position of the acquisition terminal and the teeth is in approximately the same orientation, and avoid problems such as shooting jitter, thereby achieving consistency in multi-angle shooting in different image acquisition tasks.

[0077] For example, see Figure 3-1 and Figure 3-2 , Figure 3-1 The structure of the outer side of the tooth photographed with the aid of a fixed frame is shown. Figure 3-2 The structure for auxiliary photographing of the inner side and the occlusal surface of the teeth via a fixed frame is shown. The fixed frame includes a main support frame 31, a first auxiliary support frame 32 and a second auxiliary support frame 33.

[0078] The main support frame 31 is used to clamp or support the head of the end user. Taking the head-mounted structure as an example, the main support frame 31 includes a headband, an elastic band and a mandibular positioning plate. The headband is connected to the mandibular positioning plate via the elastic band. After the end user puts on the headband, the mandibular positioning plate is pulled to the mandibular position, and the mandibular positioning plate is closely attached to the mandibular position of the end user under the action of the elastic band.

[0079] The first auxiliary bracket 32 ​​is connected to the main support frame 31, and the first auxiliary bracket is used to fix the acquisition terminal at the first shooting position when shooting the outer side of the terminal user's teeth. The first auxiliary bracket can be a metal bracket, and the first auxiliary bracket can be detachably connected to the main support frame. The detachable structure can be a plug-in type or a structure detachable by fasteners.

[0080] The second auxiliary bracket 33 is connected to the main support frame 31, and the second auxiliary bracket is used to fix the acquisition terminal at the second shooting position when shooting the inner side of the terminal user's teeth, and to fix the acquisition terminal at the third shooting position when shooting the occlusal surface of the terminal user's teeth. Since the second auxiliary bracket is required to achieve shooting of the inner side and the occlusal surface of the teeth, the part of the second auxiliary bracket extending to the inside of the oral cavity can be set as a hollow structure to prevent blocking the shooting field of view during shooting. Of course, a third auxiliary bracket can also be set, and the third auxiliary bracket is connected to the main support frame through the same structure. The second auxiliary bracket is used to fix the acquisition terminal when shooting the inner side of the terminal user's teeth, and the third auxiliary bracket is used to fix the acquisition terminal when shooting the occlusal surface of the terminal user's teeth.

[0081] It can be understood that the positioning structure between the first auxiliary bracket, the second auxiliary bracket and the acquisition terminal can be configured according to actual needs. For example, a positioning baffle is set and bent at corresponding positions on the first auxiliary bracket and the second auxiliary bracket to form a positioning baffle for limiting the end of the acquisition terminal. Of course, a magnetic structure can also be used for positioning. The first auxiliary bracket and the second auxiliary bracket are both made of hard plastic, and an iron sheet is set inside. A magnet is set on the acquisition terminal. When performing an image acquisition task, the iron sheet is attracted by the magnet on the acquisition terminal to realize the positioning of the acquisition terminal at different shooting angles.

[0082] Since teeth are distributed over a wide area in the oral cavity, it is cumbersome to take multiple images at each angle. At the same time, there are overlapping areas, and there is redundant processing when performing image comparison based on such tooth images. Based on this, an embodiment of the present invention provides another implementation method of the fixing frame 3. Please refer to Figure 4-1 and Figure 4-2 The fixing frame 3 includes a mouth opening device 41, a crossbeam 42 is provided on the mouth opening device 41, and a positioning groove 43 is provided on the crossbeam 42. The positioning groove 43 is used to cooperate with the positioning protrusion 27 on the acquisition terminal to implement positioning when taking pictures. Figure 2-2 The positioning protrusion 27 is arranged on the back side of the camera 21 , and the positioning protrusion 27 can slide freely along the length direction of the positioning groove 43 .

[0083] like Figure 4-2As shown in , the length direction of the positioning groove 43 is distributed along the width direction of the oral cavity, and the overall structure is a long strip; of course, the positioning groove 43 can also be set to a corresponding arc structure based on the arc distribution characteristics of the teeth. The first panoramic image of the upper teeth and the second panoramic image of the lower teeth can be taken through the positioning groove 43. When the panoramic image is taken, the terminal user holds the acquisition terminal 2, places the positioning protrusion 27 of the acquisition terminal 2 in the positioning groove 43, and closes to one end of the positioning groove 43, presses the shooting button of the acquisition terminal 2 to start shooting, and controls the positioning protrusion 27 to slide along the length direction of the positioning groove 43 until the positioning protrusion 27 slides to the other end of the positioning groove 43 to stop shooting. The image captured by the acquisition terminal 2 during the sliding process is the panoramic image. When shooting the upper teeth of the terminal user, the first panoramic image can be obtained, and the image content contained in the first panoramic image can cover all the upper teeth; similarly, when shooting the lower teeth of the terminal user, the second panoramic image can be obtained, and the image content contained in the second panoramic image can cover all the lower teeth. Likewise, the panoramic image capture of the outer side of the tooth may be implemented based on the interaction between the terminal user and the acquisition terminal to obtain a third panoramic image of the outer side of the tooth.

[0084] It can be understood that when performing image comparison based on panoramic images of different image acquisition tasks, the difference in changes in the entire row of teeth can be quickly and accurately obtained. Compared with the comparison processing of multiple images, the comparison redundancy can be reduced and the efficiency and accuracy of image comparison processing can be improved.

[0085] Based on the same technical concept as the dental care system, the embodiment of the present invention also provides an operation method of the dental care system, wherein the dental care system includes a medical data platform and at least one collection terminal. Figure 5 , Figure 5 The flowchart of the operation method of the dental care system is as follows. The operation method includes:

[0086] S11. Each acquisition terminal executes the image acquisition task of the corresponding terminal user in different health care periods; wherein the image acquisition task includes performing multi-angle shooting of the terminal user's teeth in different color shooting modes based on the terminal user's control, so as to obtain the terminal user's tooth images shot at multiple angles in different color shooting modes, and send them to the outside.

[0087] Specifically, since the acquisition terminal is a portable image acquisition device, the image acquisition task can be performed through the autonomous operation of the terminal user. The image acquisition task includes at least two color shooting modes, such as high-definition color mode and enhanced contrast mode, and the other two color shooting modes can also be selected based on actual needs. Each image acquisition terminal is configured with a unique serial number. Before executing the image acquisition task, identity authentication can be performed through the serial number to obtain the dental image of the corresponding terminal user. The method of sending the dental image to the outside can choose the WiFi network; it can also be transmitted to the terminal user's mobile phone via Bluetooth first, and then sent to the outside through the mobile phone. It can be understood that when transmitting to the mobile phone via Bluetooth, identity authentication can be performed simultaneously, which is convenient for the terminal user to operate, and identity recognition is more intuitive and efficient.

[0088] In actual applications, the inner side and occlusal surface of the teeth need to be photographed in the oral cavity. When photographing in winter or in low temperature scenes, fog will be formed on the camera of the acquisition terminal, making the obtained tooth image less clear. Based on this, a heating element is set around the camera to determine whether there is a risk of fogging before taking the tooth image. When there is a risk of fogging, the heating element is started. When the working time of the heating element or the heating temperature reaches a preset value, the acquisition terminal is placed in the oral cavity to take the tooth image, so as to reduce the fog caused by the temperature difference and improve the clarity of the tooth image.

[0089] The risk of fogging can be determined based on the time when the image acquisition task is executed, or based on the temperature data obtained by the temperature sensor set on the acquisition terminal. For example, when the execution time of the image acquisition task is in winter, it means that there is a risk of fogging; when the temperature data obtained by the temperature sensor is lower than the temperature threshold, it can also be said that there is a risk of fogging. The heating element can be directly arranged around the periphery of the camera, and the periphery of the camera can be heated to a suitable temperature. After heating the periphery of the camera, the temperature difference between the oral cavity and the acquisition terminal can be reduced, and the water vapor in the oral cavity is not easy to adhere to the camera, thereby reducing the impact of fog on the capture of dental images.

[0090] It is understandable that the heating element can be a heating wire or a heating resistor. When the periphery of the camera is set as a recessed structure, the heating element can be set in the recessed structure and placed under the metal plate of the convex structure. Since the camera is located in the middle of the recessed structure, the heat emitted by the heating element can cover the periphery of the camera, thereby effectively reducing the impact of fog on the shooting of dental images.

[0091] S12. Receive dental images of each terminal user in different image acquisition tasks and comparison results of dental images in the same color shooting mode in different image acquisition tasks via the medical data platform, and output dental care results corresponding to the terminal user.

[0092] Specifically, the medical data platform can store the dental images of each terminal user in a corresponding manner, such as implementing corresponding storage for the serial number of the acquisition terminal. When comparing dental images of the same color shooting mode for different image acquisition tasks, it can be implemented by medical personnel to determine the differences in the images uploaded at each time point and to determine the abnormal conditions of the teeth. Before implementing the dental image comparison, each dental image can be marked with information according to preset marking items through the acquisition terminal or the medical data platform, wherein the marking items include the corresponding shooting time of the dental image, and the marking items can also include the identity information of the terminal user, such as the serial number of the acquisition terminal, user name, etc. The information marking can be based on a watermark, for example, after the dental image is shot, mark: March 10, 2024 21:36.

[0093] Considering the huge workload of manually reviewing a large number of images, and the difficulty of manually reviewing images to find various subtle changes on different tooth images in a short period of time, when the embodiment of the present invention actually performs the image comparison work, a computer system is used to perform image comparison analysis. The computer system can identify pixel-level differences for two or more tooth images of the same color shooting mode at different time periods, thereby easily identifying changes such as deformation, color change, and surface wear of teeth in a short period of time. The computer system processes images and analyzes the results, and has the characteristics of high efficiency and accuracy. When the computer system implements image comparison, a convolutional neural network model can be constructed and trained. After the training, when it can accurately implement image recognition, the tooth images of different image acquisition tasks are input into the trained convolutional neural network model, and the comparison results of the tooth images are obtained based on the output results of the convolutional neural network model.

[0094] Exemplarily, step S12 includes sub-steps S12-1 to S12-3, which are specifically described as follows:

[0095] S12-1. Number the teeth of the current terminal user according to the arrangement order of the teeth in the tooth image. Based on the tooth image, each tooth of each terminal user can be numbered in a fixed order, that is, each tooth has a corresponding fixed number. The number can be Arabic numerals or other coding methods, such as numbering based on the type and position of the tooth, which is not specifically limited here.

[0096] S12-2. Obtain the pathological results of the teeth with corresponding numbers according to the image comparison results of the same color shooting mode and the same numbered teeth in different image acquisition tasks. Since each tooth has a corresponding number, the tooth images for different image acquisition tasks can be accurately compared. For example, when performing image comparison of the outer surface of the teeth in two adjacent periodic image acquisition tasks, the target area of ​​each tooth image is extracted based on the number of each tooth. The target area is the image area that only contains the tooth. The two target areas are compared to obtain the pathological results of the teeth with corresponding numbers. The pathological results can be characterized based on actual needs, such as whether the area of ​​dental plaque has become larger, whether there is severe wear, etc.

[0097] Further, sub-step S12-2 is implemented by the following steps. Specifically including:

[0098] In the first step, the image comparison results of each tooth in the same color shooting mode are compared according to multiple preset health items to extract change features to obtain the comparison change value of each health item. Multiple health items include tooth shape change, tooth color change and tooth wear change. Each health item implements health evaluation from different dimensions. Analysis from the dimension of shape change can help identify dental health problems, such as uneven teeth or malocclusion, which may affect oral function and aesthetics. Changes in tooth color usually reflect oral hygiene and eating habits, such as pigmentation or tooth demineralization, which is crucial to judging the health status of teeth. The degree of tooth wear can reveal excessive bite pressure or bad bite habits, and long-term wear may cause tooth sensitivity or damage. Combining these evaluations can help to detect and intervene in potential dental problems early, thereby maintaining overall oral health and function. By extracting change features from the image comparison results, the degree of change of different health items can be quantified, and then the change characteristics of teeth can be accurately analyzed.

[0099] The second step is to generate a health curve for each tooth based on the contrast change value of each health item, where the health curve is a curve showing the contrast change value over time. The health curve provides an intuitive dynamic analysis of oral health by plotting the contrast change value of each tooth's health item (such as shape, color, and wear) over time. These curves show the changes in the health status of the teeth at different time points, helping to identify potential health problems or trends. For example, the shape change curve can reveal whether the teeth have a tendency to deform or become uneven, the color change curve can show whether the teeth have changed color due to pigmentation or other factors, and the wear change curve can reflect the wear process of the teeth and its relationship to occlusal problems.

[0100] The third step is to obtain the pathological results of the corresponding numbered teeth according to the health care curve of each tooth. Through the health care curve obtained by the above analysis, it is possible to observe how the health status of each tooth changes over time, and determine it as the pathological result of the corresponding numbered tooth.

[0101] For example, the above analysis can be used to determine the degree of wear of the upper left molar numbered 1. The wear condition analyzed from each uploaded image can be expressed numerically. A series of numerical values ​​form a wear degree curve that changes along the time axis. Both end users and dentists can intuitively see the changes in the degree of wear of the tooth and intervene in time. This processing method can also help dentists make scientific diagnoses and personalized health care plans. The advantage of this method is that it provides detailed time series data, which helps to evaluate the effectiveness of health care measures, adjust oral care strategies, and thus improve overall oral health.

[0102] S12-3. Obtain dental care results based on the pathological results of all teeth of the current end user. The health status of each tooth, such as tooth decay, gum disease, wear and color change, is analyzed in the above manner, and this information is combined to form a comprehensive health assessment. By evaluating the pathological conditions of all teeth, the strengths and weaknesses of overall oral health can be identified, so as to formulate an effective health care plan.

[0103] Since there are many health care items involved in teeth, when performing image acquisition tasks, corresponding health care items can also be determined based on the age group of the terminal user. Corresponding relationships are established according to different age groups and corresponding health care items. For example, the age group is divided into multiple intervals, each interval corresponds to a dental care set, and the dental care set has multiple health care items to apply to terminal users of different age groups to implement dental care. When implementing the shooting of dental images, based on the age of the current terminal user in the established corresponding relationship, multiple current health care items of the current terminal user are determined, and based on the multiple current health care items, dental image shooting in the corresponding color shooting mode is implemented.

[0104] For example, for children under 12 years old, the risk of dental caries is relatively high, and it is necessary to pay attention to the changing characteristics of dental plaque and implement corresponding health care items in enhanced contrast mode; for adolescents aged 12-18, the occlusion and alignment problems are more prominent, and it is necessary to pay attention to the shape changes of the teeth. Health care items include shape inspection, and each health care item is inspected in high-definition color mode, enhanced contrast mode, and black and white mode. For middle-aged and elderly end users, the probability of gingivitis is higher, and health care items include gum inspection. Multiple health care items can be taken in high-definition color mode, enhanced contrast mode, and infrared light mode. Performing image acquisition tasks in the above manner can improve the accuracy of tooth images for end users of different ages, which is convenient for dentists to compare and refer to.

[0105] When determining the implementation of dental care items, the health care items to be implemented can also be determined based on more personal information of the terminal user, including historical health care records, gender, living habits, etc. The historical health care records show whether the terminal user has caries, orthodontics, etc., and the health care items implemented by the terminal user can be appropriately increased or decreased through the historical health care records; there are also differences in the health care items implemented by different genders. For example, women may experience gum problems during pregnancy, while men are more likely to have periodontal disease, etc., and corresponding health care items and color shooting modes for corresponding health care items can be set accordingly; living habits can be obtained through questionnaires, such as whether to stay up late, eat midnight snacks, etc., and corresponding health care items and color shooting modes are set based on living habits to improve the accuracy of health care items and color shooting mode configuration in image acquisition tasks.

[0106] The technical solution provided in the embodiments of the present invention has at least the following technical effects or advantages:

[0107] Each acquisition terminal performs the image acquisition task of the corresponding terminal user in different health care periods; since the image acquisition task includes multi-angle shooting of the terminal user's teeth in different color shooting modes based on the terminal user's control, the terminal user's tooth images taken at multiple angles in different color shooting modes can be obtained, and the tooth images can be sent to the medical data platform; the medical data platform receives the tooth images taken at multiple angles in different color shooting modes by each terminal user, as well as the comparison results of the tooth images in the same color shooting mode in different image acquisition tasks, and outputs the corresponding terminal user's dental care results. This technical solution enables the terminal user to independently take their tooth images through the acquisition terminal and upload them to the medical data platform. The changing characteristics of the dental health status can be extracted under different color shooting modes, and the accuracy of the dental care results obtained by image comparison is better; at the same time, the terminal user has more flexible time and freer scenes to implement dental care, which can help users to regularly implement health care, discover the trend of dental lesions as early as possible, and take reasonable ways of using and protecting teeth to maintain dental health, so that the user's teeth can receive timely and accurate health care.
