Description

Technical Field

[0001] The present invention relates to the field of intelligent technology of traditional Chinese medicine, and in particular to a tongue diagnosis instrument based on a high-resolution camera and a high-frame-rate camera. Background Art

[0002] Traditional tongue diagnosis relies heavily on the doctor's personal experience and intuitive feelings to interpret changes in the tongue's spirit, color, shape, and posture. This judgment method lacks a unified quantitative standard. Different doctors may have different interpretations of the same tongue image, resulting in subjective and inconsistent diagnostic results.

[0003] For example, when judging tongue color, doctors need to rely on the naked eye to observe the color changes of the tongue, but the tongue color may vary under different light and at different time periods, which brings challenges to accurate judgment.

[0004] Because traditional tongue diagnosis lacks objective and quantitative analysis methods, its diagnostic results are difficult to verify repeatedly. This means that even under the same conditions, different doctors or the same doctor performing tongue diagnosis on the same patient at different times may come to different conclusions.

[0005] In addition, traditional tongue diagnosis mainly focuses on static tongue information, such as the color and shape of the tongue, but ignores dynamic characteristics, such as tongue movement and slight changes in color. These dynamic characteristics are important for comprehensive evaluation of tongue images, but are difficult to be effectively captured and analyzed in traditional tongue diagnosis.

[0006] For example, in certain disease states, the color of the tongue may change slightly as the condition changes. Such changes may be difficult to detect in a timely manner in traditional tongue diagnosis, thus affecting the accuracy and timeliness of the diagnosis.

[0007] With the rapid development of artificial intelligence (AI), modern medical diagnostics are moving towards intelligent and automated methods. However, traditional tongue diagnosis remains reliant on manual judgment, lacking intelligent auxiliary tools and analytical methods. This not only limits the widespread application and further development of tongue diagnosis technology, but also increases the workload and diagnostic difficulty for doctors. For example, when processing large amounts of patient data, traditional tongue diagnosis methods struggle to provide quick and accurate diagnostic results. Intelligent tongue diagnosis devices, however, can achieve rapid and accurate interpretation of tongue images through image recognition and algorithmic analysis. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a tongue diagnosis instrument based on a high-resolution camera and a high-frame rate camera, which realizes a comprehensive, objective and quantitative analysis of tongue images.

[0009] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0020] Furthermore, an industrial computer is fixed inside the housing structure and uses an image processing algorithm to perform real-time analysis and storage of tongue images to obtain a tongue diagnosis report, including:

[0021] Using an image processing algorithm, extracting features related to traditional Chinese medicine tongue diagnosis from the images captured by the high-resolution camera and the high-frame rate camera, including the color, shape, and texture of the tongue;

[0022] Real-time analysis of the extracted features related to TCM tongue diagnosis, including comparison with a preset tongue image database to obtain comparison results;

[0023] Based on the comparison results, the industrial computer generates a tongue diagnosis report, including a description of tongue characteristics, disease diagnosis, and recommended examinations.

[0024] Furthermore, the dual-camera device includes:

[0025] High-resolution camera, through the camera stand and Inch screws are fixed to the bottom metal bracket for collecting images of the tongue surface and tongue base;

[0026] High frame rate camera, through the groove structure of the USB camera bracket and Inch screws are fixed to the sheet metal bracket to capture dynamic tongue images in real time;

[0027] The high-resolution camera and the high-frame-rate camera are connected to the industrial computer via a data cable to achieve synchronous image acquisition and processing.

[0028] Furthermore, the USB camera bracket is fixed to the bottom of the shell structure through the sheet metal bracket.

[0029] Furthermore, the bottom metal bracket supports the industrial computer; the sheet metal bracket supports the camera bracket of the high-resolution camera.

[0030] Furthermore, the support structure further includes:

[0031] The metal bracket behind the camera is provided with a hollow slot for installing the high frame rate camera.

[0032] The above solution of the present invention includes at least the following beneficial effects:

[0033] By using a high-resolution camera, the tongue diagnosis instrument can capture subtle changes in the tongue's texture, color, and shape, providing doctors with richer diagnostic information. A high-frame-rate camera can record dynamic changes in the tongue's surface in real time, such as tongue movement and changes in the thickness of the tongue coating, helping doctors to more accurately judge tongue images and improve the objectivity of diagnosis. Through standardized image acquisition and processing processes, the tongue diagnosis instrument can reduce the impact of human factors on tongue diagnosis results and achieve standardization of tongue diagnosis. At the same time, with the help of advanced image processing technology and algorithms, the tongue diagnosis instrument can perform quantitative analysis of tongue images, such as quantitative evaluation of indicators such as color depth and texture thickness, providing more accurate data support for tongue diagnosis.

[0034] The tongue diagnosis instrument utilizes automated data acquisition and processing technology, enabling rapid collection and analysis of tongue images, shortening the time required for tongue diagnosis. Furthermore, its compact size, ease of operation, and portability make it suitable for use in a variety of environments, enhancing the convenience of tongue diagnosis. The high-frame-rate camera can capture rapid changes in the tongue surface, providing doctors with dynamic information on tongue images. This is valuable for analyzing tongue movement patterns and tongue coating trends, helping doctors gain a more comprehensive understanding of their patients' health.

[0035] The tongue diagnosis instrument uses a diffuse dome light source to ensure even light distribution, avoiding problems such as uneven illumination and poor color reproduction. This design makes the collected tongue images clearer and more realistic, helping doctors to more accurately judge tongue characteristics. The tongue diagnosis instrument's hardware structure, including components such as the camera bracket and sheet metal bracket, is independently designed to ensure the device's stability and durability. Furthermore, through a rational layout and bracket design, the tongue diagnosis instrument achieves efficient collaboration between the dual-camera system, improving the device's overall performance.

[0036] The tongue diagnosis instrument's hardware design takes into account ease of maintenance and upgrades. The modular design of its components facilitates disassembly and replacement. When equipment upgrades or maintenance are required, users can easily complete these operations, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] like Figures 1 to 5 As shown, an embodiment of the present invention proposes a tongue diagnosis instrument based on a high-resolution camera and a high-frame rate camera, comprising:

[0045] The outer shell structure is composed of an upper shell 1, a bottom plate upper cover 2, a bottom plate lower cover 3 and a back plate 7, forming a closed optical path space;

[0046] A dome light source 5 is installed inside the upper shell 1 to provide uniform lighting;

[0047] A light source switch 6 is provided on the surface of the upper shell 1 and is electrically connected to the dome light source 5 for controlling the start and stop of the light and adjusting the brightness;

[0048] The industrial computer 15 is fixed inside the housing structure and realizes real-time analysis and storage of tongue images through image processing algorithms;

[0049] The display screen 4 is fixed to the upper housing 1 and electrically connected to the industrial computer 15;

[0050] A dual-camera device is used to simultaneously capture high-resolution static images of the tongue surface and dynamic images of the tongue body;

[0051] The support structure includes a bottom metal support 10, a sheet metal support 11, a camera rear metal support 9 and a USB camera support 12, which are used to fix the dual-camera device and adjust the angle of the dual-camera device.

[0052] In an embodiment of the present invention, the upper shell 1, the upper cover 2 of the base plate, the lower cover 3 of the base plate and the back plate 7 together constitute a closed optical path space, which effectively prevents interference from external light and ensures the accuracy and stability of tongue image acquisition. The dome light source 5 is installed inside the upper shell 1 to provide uniform lighting conditions and ensure the consistency of light when acquiring images of the tongue surface and tongue base. The light source switch 6 is set on the surface of the upper shell 1 and is electrically connected to the dome light source 5. The doctor or operator can control the start and stop of the light and adjust the brightness by operating the light source switch 6 to adapt to different environments and patient needs.

[0053] The dual-camera system includes a high-resolution camera and a high-frame-rate camera, which are used to capture high-resolution static images of the tongue surface and dynamic images of the tongue body, respectively. The high-resolution camera can capture subtle features of the tongue surface, such as the tongue coating and tongue texture, providing detailed image data for TCM tongue diagnosis. The high-frame-rate camera can capture dynamic changes in the tongue body, such as movement and color changes, in real time, which helps analyze the functional status and possible pathological changes of the tongue. The captured images are transmitted via a data cable to the industrial computer 15, which has a built-in image processing algorithm that can analyze and store tongue images in real time.

[0054] The display screen 4 is fixed to the upper shell 1 and electrically connected to the industrial computer 15 for real-time display of the collected tongue images and analysis results. Doctors or operators can view the tongue images and analysis results through the display screen 4 and perform interactive operations, such as adjusting acquisition parameters, selecting analysis modes, etc. The bracket structure includes a bottom metal bracket 10, a sheet metal bracket 11, a rear metal bracket 9 for the camera, and a USB camera bracket 12, which are used together to fix the dual-camera device and adjust its angle. By adjusting the bracket structure, doctors or operators can adjust the position and angle of the camera to adapt to the tongue position and morphology of different patients, ensuring the accuracy and completeness of image acquisition.

[0055] The combination of high-resolution and high-frame-rate cameras simultaneously captures static features of the tongue surface and dynamic changes in the tongue body, providing more comprehensive and accurate image data for Traditional Chinese Medicine tongue diagnosis. The enclosed optical path and uniform lighting conditions ensure consistent and stable image acquisition, reducing interference from external light and improving diagnostic accuracy. The image processing algorithm built into the industrial computer analyzes tongue images in real time and rapidly delivers diagnostic results, significantly reducing diagnostic time. The display screen displays analysis results in real time, allowing doctors to instantly review and make decisions, further improving diagnostic efficiency. The intelligently designed bracket structure secures the dual-camera assembly and adjusts its angle to accommodate the tongue position and morphology of different patients, enhancing the device's flexibility. The device's overall structure is compact and easy to operate, making it portable and portable, making it suitable for use in various medical settings. By integrating Traditional Chinese Medicine tongue diagnosis with modern technology, the system achieves digitized and objective analysis of tongue images, contributing to the standardization of Traditional Chinese Medicine tongue diagnosis.

[0056] like Figures 1 to 5 As shown, the housing structure further includes:

[0057] The display screen hinge bracket 8 is used to adjust the angle of the display screen 4 .

[0058] In an embodiment of the present invention, the display screen hinge bracket 8 is fixedly connected between the upper shell 1 and the display screen 4, allowing the display screen 4 to be adjusted in angle within a certain range. A doctor or operator can adjust the angle of the display screen 4 manually or electrically as needed to achieve the best visual effect in different usage scenarios. The display screen hinge bracket 8 was designed with structural stability and durability in mind, ensuring that the entire device remains stable without shaking or tilting when the display screen angle is adjusted. Furthermore, the display screen hinge bracket 8 has a certain load-bearing capacity, capable of supporting the weight of the display screen 4 and maintaining stable performance during prolonged use.

[0059] The display hinge bracket 8 allows the doctor or operator to adjust the angle of the display screen according to actual needs, making it more comfortable and convenient to view tongue images and analyze results. This increased flexibility helps reduce eye fatigue and neck discomfort during long-term use, and improves the doctor's work efficiency and job satisfaction. In different usage scenarios, such as changes in patient posture, changes in lighting conditions, etc., the display hinge bracket 8 can help the doctor quickly adjust the angle of the display screen to adapt to different observation needs. This increased adaptability makes the tongue diagnosis instrument more suitable for various complex medical environments and patient conditions, and improves the practicality and application range of the equipment. The display hinge bracket 8 is designed with attention to structural stability and durability to ensure that the entire device can remain stable when adjusting the angle of the display screen. Maintaining this stability helps reduce problems such as image blur or analysis errors caused by shaking or tilting of the equipment, and improves the accuracy and reliability of diagnosis.

[0060] like Figures 1 to 5 As shown, the industrial computer 15 is fixed inside the housing structure and uses an image processing algorithm to perform real-time analysis and storage of tongue images to obtain a tongue diagnosis report, including:

[0061] Using image processing algorithms, extracting features related to TCM tongue diagnosis from the images captured by the high-resolution camera 16 and the high-frame-rate camera 17, including the color, shape, and texture of the tongue;

[0062] Real-time analysis of the extracted features related to TCM tongue diagnosis, including comparison with a preset tongue image database to obtain comparison results;

[0063] Based on the comparison results, the industrial computer 15 generates a tongue diagnosis report, including a description of tongue characteristics, a diagnosis of the disease, and recommended examinations.

[0064] In this embodiment of the present invention, the industrial computer 15 is screwed into the tongue diagnosis instrument's housing to prevent it from falling off or being damaged by movement or vibration during operation. The industrial computer 15 houses a high-performance processor and storage device. When the high-resolution camera 16 and high-frame-rate camera 17 capture tongue images, these image data are transmitted to the industrial computer 15 in real time. The industrial computer 15 then uses pre-installed image processing algorithms to process and analyze the received image data, extracting key information and storing it on its internal storage device. Based on this information, the industrial computer 15 generates a detailed tongue diagnosis report.

[0065] The high-resolution camera 16 captures static, high-definition images of the tongue surface, while the high-frame-rate camera 17 captures dynamic changes in the tongue. After receiving these two types of images, the industrial computer 15 processes them using image processing algorithms (such as edge detection, color space conversion, and texture analysis) to extract features relevant to TCM tongue diagnosis, such as the tongue's color, shape, and texture. The industrial computer 15 contains a built-in knowledge base related to TCM tongue diagnosis and a pre-set tongue image database. After extracting tongue image features, the industrial computer 15 uses these pre-set data and algorithms to perform real-time analysis of the extracted features, including comparisons with the pre-set tongue image database to determine whether the features meet the diagnostic criteria for a specific condition. The industrial computer 15 then compares each extracted tongue image feature with standard tongue images in the pre-set tongue image database. Comparison results are obtained by calculating similarities or applying classification algorithms. These results include the classification of the tongue image features and the likelihood of the condition. Based on these comparison results, the industrial computer 15 uses natural language generation technology to generate a detailed tongue diagnosis report. This report may include a description of tongue characteristics, disease diagnosis, recommended examinations, and other aspects, providing doctors with a comprehensive diagnostic reference.

[0066] Suppose a patient comes to see a doctor. The doctor uses a tongue diagnosis device powered by a high-resolution camera and a high-frame-rate camera to examine their tongue. The high-resolution camera captures a clear image of the patient's tongue, showing a thick, yellowish coating; the high-frame-rate camera, on the other hand, captures the patient's tongue's slight tremors as they speak. After receiving these images, the industrial computer 15 uses an image processing algorithm to extract features such as the tongue's color, shape, and texture, and compares them with a pre-set database of tongue images. The comparison results indicate that the patient's tongue features are consistent with internal damp-heat syndrome. The industrial computer 15 then generates a tongue diagnosis report, indicating that the patient may have internal damp-heat syndrome and recommending further examination and treatment.

[0067] By utilizing image processing algorithms and a pre-set tongue image database, the industrial computer 15 can accurately extract and analyze tongue image features in real time, thereby improving diagnostic accuracy. Compared to traditional manual tongue diagnosis, this method reduces errors caused by subjective judgment. The industrial computer 15 can process and analyze tongue images in real time, generating detailed tongue diagnosis reports, significantly shortening diagnosis time. Doctors can instantly view the report results, make judgments, and formulate treatment plans. By utilizing modern scientific and technological means, the tongue diagnosis instrument achieves digitization and objective analysis of tongue images, helping to promote the objectification and standardization of tongue diagnosis in Traditional Chinese Medicine (TCM). At the same time, the pre-set tongue image database provides doctors with unified diagnostic standards and reference bases. The tongue diagnosis instrument not only improves the accuracy and efficiency of diagnosis, but also provides new technical means and reference bases for clinical diagnosis and treatment in TCM. It helps doctors gain a more comprehensive understanding of the patient's condition and formulate more reasonable treatment plans.

[0068] like Figures 1 to 5 As shown, the dual-camera setup includes:

[0069] High resolution camera 16, through camera bracket 13 and Inch screws 14 are fixed to the bottom metal bracket 10 for collecting images of the tongue surface and tongue base;

[0070] High frame rate camera 17, through the groove structure of USB camera bracket 12 and Inch screws 14 are fixed to the sheet metal bracket 11 to capture the dynamic tongue image in real time;

[0071] The high-resolution camera 16 and the high-frame-rate camera 17 are connected to the industrial computer 15 via a data line to achieve synchronous image acquisition and processing.

[0072] In this embodiment of the present invention, a high-resolution camera 16 is securely fastened to the bottom metal bracket 10 via a camera bracket 13 and inch screws 14, ensuring a stable position and angle during imaging. When the tongue diagnostic device begins operating, the high-resolution camera 16 receives instructions from the industrial computer 15 and begins capturing images of the tongue surface and base. The captured image data is transmitted in real time via a data cable to the industrial computer 15 for subsequent image processing and analysis.

[0073] The high-frame-rate camera 17 is secured to the sheet metal bracket 11 via the grooves in the USB camera bracket 12 and inch screws 14. This design ensures camera stability and facilitates adjustment of the camera's shooting angle. Unlike the high-resolution camera 16, the high-frame-rate camera 17's primary task is to capture dynamic changes in the tongue, such as movement and color changes, in real time. The collected dynamic tongue image data is also transmitted in real time via a data cable to the industrial computer 15 for simultaneous processing and analysis.

[0074] The industrial computer 15 serves as the control center for the entire tongue diagnosis instrument, coordinating the operations of the high-resolution camera 16 and the high-frame-rate camera 17. Through precise time synchronization, the industrial computer 15 ensures high consistency in image acquisition between the two cameras, enabling synchronized image acquisition. The captured image data is processed by the industrial computer 15's image processing algorithm to extract features relevant to Traditional Chinese Medicine tongue diagnosis, such as the tongue's color, shape, texture, and dynamic changes.

[0075] By simultaneously capturing static images of the tongue surface and dynamic images of the tongue body, the dual-camera system provides a more comprehensive and accurate diagnostic basis for Traditional Chinese Medicine tongue diagnosis. Static images can reveal subtle features of the tongue surface, such as the tongue coating and texture, while dynamic images can reveal the functional status and possible pathological changes of the tongue body. The dual-camera system enables simultaneous image acquisition and processing, shortening diagnostic time. Doctors can instantly review and analyze the captured image data, quickly making diagnoses and formulating treatment plans. Compared to traditional manual tongue diagnosis, the dual-camera system reduces the errors caused by subjective judgment. By comparing and analyzing image processing algorithms with a pre-set tongue image database, the dual-camera system can provide more objective and accurate diagnostic results.

[0076] like Figures 1 to 5 As shown, the USB camera bracket 12 is fixed to the bottom of the shell structure through the sheet metal bracket 11.

[0077] In an embodiment of the present invention, the USB camera bracket 12 is designed with specific fixing structures, such as grooves, which are used to connect to the sheet metal bracket 11. The sheet metal bracket 11 is designed with corresponding protrusions, holes or slots based on the fixing structure of the USB camera bracket 12 to ensure that the two can fit tightly and be firmly connected. During the installation process, the fixing structure of the USB camera bracket 12 is aligned with the corresponding position of the sheet metal bracket 11, and the two are fixed together by screws. The sheet metal bracket 11 is fixed by screws and firmly installed at the bottom of the outer shell structure, thereby forming a stable support structure. As an intermediate connecting member, the sheet metal bracket 11 not only fixes the USB camera bracket 12 to the bottom of the outer shell structure, but also plays a supporting and positioning role. It ensures that the USB camera bracket 12 and the high frame rate camera 17 thereon can maintain a stable position and angle to avoid shaking or deviation during shooting. At the same time, the design of the sheet metal bracket 11 also takes into account factors such as heat dissipation and electromagnetic shielding to ensure the normal operation and image quality of the high frame rate camera 17.

[0078] The USB camera bracket 12, sheet metal bracket 11, and bottom shell structure form a complete camera support system. This system not only provides stable support and positioning for the high-frame-rate camera 17, but also works in conjunction with other components (such as the high-resolution camera 16 and industrial computer 15) to realize the tongue diagnosis instrument's various functions. During operation, the various components are connected through data cables, power cables, etc., forming an organic whole, jointly completing tasks such as image acquisition, processing, and analysis.

[0079] As a supporting structure, the sheet metal bracket 11 has sufficient strength and stability to ensure that the USB camera bracket 12 and the high frame rate camera 17 thereon maintain a stable position and angle during the shooting process, avoiding image jitter and blur. By using inch screws to fix the USB camera bracket 12 to the sheet metal bracket 11, the entire installation process is simple and quick. When maintenance or camera replacement is required, the USB camera bracket 12 can be easily removed by loosening the screws, which improves the convenience of maintenance. The design of the USB camera bracket 12 allows it to adapt to different shooting needs by adjusting its position and angle. This flexibility allows the tongue diagnosis instrument to adapt to a wider variety of patients and shooting scenarios, improving its practicality and application range.

[0080] like Figures 1 to 5 As shown, the bottom metal bracket 10 supports the industrial computer 15 ; the sheet metal bracket 11 supports the camera bracket 13 of the high-resolution camera 16 .

[0081] In an embodiment of the present invention, the bottom metal bracket 10 serves as a stable foundation for the entire tongue diagnosis instrument, and its design has sufficient strength and rigidity to withstand the weight of the industrial computer 15 and the vibrations generated during operation. The industrial computer 15 is mounted on the bottom metal bracket 10 by appropriate fixing methods (such as screws) to ensure a close connection and stable support between the two. During operation, the bottom metal bracket 10 provides a stable platform for the industrial computer 15 to ensure its normal operation and high efficiency of data processing. The sheet metal bracket 11 is designed with a specific structure and shape to adapt to and support the camera bracket 13 of the high-resolution camera 16. The camera bracket 13 is mounted on the sheet metal bracket 11 by precise positioning and fixing methods (such as screws, slots, etc.) to ensure that the high-resolution camera 16 can be accurately aligned with the shooting target. The sheet metal bracket 11 not only provides stable support for the camera bracket 13, but also protects the high-resolution camera 16 from interference from the external environment through its structural characteristics (such as rigidity and corrosion resistance).

[0082] The solid support of the bottom metal bracket 10 and the sheet metal bracket 11 ensures the stability of the industrial computer 15 and the high-resolution camera 16 during operation, which helps to reduce equipment damage or data loss caused by vibration or external impact, and improves the reliability and durability of the tongue diagnosis instrument. The precise design and support of the sheet metal bracket 11 ensure that the high-resolution camera 16 can accurately align with the tongue surface for shooting, which helps to obtain clear and accurate tongue images and provide a reliable diagnostic basis for traditional Chinese medicine tongue diagnosis. The support structure design of the bottom metal bracket 10 and the sheet metal bracket 11 takes into account the convenience of maintenance. When maintenance or replacement of equipment is required, the industrial computer 15 or the high-resolution camera 16 can be easily disassembled and installed, reducing maintenance costs and time. The compact design of the bottom metal bracket 10 and the sheet metal bracket 11 makes the overall structure of the tongue diagnosis instrument more compact and reasonable.

[0083] like Figures 1 to 5 As shown, the support structure also includes:

[0084] The metal bracket 9 behind the camera is provided with a hollow slot for mounting the high frame rate camera 17 .

[0085] In an embodiment of the present invention, the camera rear metal bracket 9 is a metal component with a specific shape and structure, and its design takes into account the installation requirements and heat dissipation performance of the high frame rate camera 17. The bracket is provided with hollow grooves, which not only reduce the weight of the bracket, but also provide channels for ventilation and heat dissipation, which helps to maintain the stability of the high frame rate camera 17 during long-term operation. During the installation process, the high frame rate camera 17 is connected to the camera rear metal bracket 9 through the USB camera bracket 12 (or other fixing methods). The USB camera bracket 12 may be fixed to the camera rear metal bracket 9 by a groove structure, screws or other fasteners to ensure that the camera is firmly mounted on the bracket. The camera rear metal bracket 9 is then connected to the bottom of the outer shell structure through the sheet metal bracket 11 to form a complete support structure.

[0086] The design of the rear metal bracket 9 of the camera allows for precise positioning and angle adjustment of the high frame rate camera 17. By adjusting the connection position between the USB camera bracket 12 and the rear metal bracket 9 of the camera, the shooting angle and field of view of the camera can be changed to adapt to different shooting needs. This adjustment mechanism enables the high frame rate camera 17 to accurately capture the dynamic changes of the tongue surface and provide clear image data for traditional Chinese medicine tongue diagnosis. The rear metal bracket 9 of the camera, the USB camera bracket 12, the sheet metal bracket 11 and the bottom of the shell structure together constitute a stable camera support system. This system not only ensures the stable operation of the high frame rate camera 17, but also works in conjunction with other components (such as high-resolution camera 16, industrial computer 15, etc.) to realize the various functions of the tongue diagnosis instrument. During operation, the various components are connected together by data cables, power cables, etc. to form an organic whole, and jointly complete tasks such as image acquisition, processing and analysis.

[0087] The design of the metal bracket 9 at the rear of the camera provides a stable support for the high frame rate camera 17, reducing camera shake and image blur caused by vibration or external impact, which helps to improve the accuracy and reliability of image acquisition and provide a more accurate diagnostic basis for traditional Chinese medicine tongue diagnosis. The hollow groove design on the bracket increases the area for ventilation and heat dissipation, which helps to reduce the temperature of the high frame rate camera 17 during operation. Good heat dissipation performance can extend the service life of the camera and reduce equipment failures and performance degradation caused by overheating. The design of the metal bracket 9 at the rear of the camera takes into account the convenience of installation and flexibility of adjustment. The addition of the metal bracket 9 at the rear of the camera makes the overall structure of the tongue diagnosis instrument more reasonable and compact. It not only provides a stable support for the camera, but also optimizes the heat dissipation performance and installation convenience of the equipment through its structural characteristics, thereby improving the overall performance and reliability of the tongue diagnosis instrument.

[0088] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
