Description

Technical Field

[0001] The present invention belongs to the technical field of tongue image collection, and in particular relates to a multimodal tongue image collection system and device combined with millimeter wave radar. Background Art

[0002] Tongue diagnosis instruments adhere to the principles of Traditional Chinese Medicine (TCM) and utilize modern technology to extract and process tongue image characteristics, achieving objective and quantifiable results. Technological advancements, particularly in image processing, machine learning, and artificial intelligence, have significantly advanced tongue and facial diagnosis. This tongue image acquisition solution utilizes a fixed light source and a closed acquisition environment, integrating numerous key technologies in optics, image acquisition and processing, and image recognition.

[0003] Millimeter-wave radar detects targets by emitting electromagnetic waves and receiving reflected electromagnetic waves. Its operating principle is similar to that of echolocation by bats or dolphins, but it uses electromagnetic waves instead of sound waves. Millimeter-wave radar can accurately capture cardiac shock waves, respiratory waves, and body movement waves by scanning the human body surface at high speed. The waveforms are complete and detailed. This allows accurate calculation of the patient's heart rate and respiratory rate, with a displacement resolution of 0.02mm and a heart rate detection range exceeding 165 beats. Furthermore, AI data mining can be used to analyze heart rate variability (HRV), respiratory variability (BRV), and apnea.

[0004] Among existing technical solutions, patent inventions related to Traditional Chinese Medicine tongue diagnosis are emerging in large numbers, primarily focusing on optimizing the device and intelligently upgrading the collection method of tongue diagnosis instruments. One patent invention, particularly close to this solution, utilizes a multimodal model to combine tongue images collected by the tongue diagnosis instrument with preliminary diagnostic information from the doctor, constructing a multimodal tongue diagnosis model that integrates image and text data, further improving the accuracy and practicality of tongue diagnosis.

[0005] At the same time, the application of millimeter-wave radar in human body status monitoring has become quite mature. By collecting chest signals and conducting in-depth analysis of echo data, it can accurately extract breathing and heartbeat signals. Related patented inventions such as the main feature breathing and heart rate detection method and system have been widely used in the field of health monitoring.

[0006] However, it is worth noting that although TCM tongue diagnosis and millimeter-wave radar technology have made significant progress in their respective fields, the two technologies have not been effectively integrated in the existing technology. Due to the lack of integration, the information obtained by TCM tongue diagnosis and millimeter-wave radar is in an isolated state and cannot form a comprehensive health monitoring system, resulting in one-sided diagnostic information, affecting the accuracy and completeness of the diagnosis, and unable to provide patients with more accurate and comprehensive personalized treatment plans. To this end, a multimodal tongue image acquisition system and device combined with millimeter-wave radar is proposed. Summary of the Invention

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] like Figure 1 As shown, a multimodal tongue image acquisition device combined with millimeter wave radar includes:

[0043] A housing assembly, comprising a housing front cover 2, a housing body 6 and a housing rear cover 8, for accommodating and protecting components installed therein;

[0044] A power transformer 10 is used to provide power to the tongue image collection device;

[0045] The elliptical inner container 5 is arranged inside the outer shell assembly, and the surface of the elliptical inner container is evenly covered with LED light sources;

[0046] A diffuser 3 is provided in front of the LED light source to reduce the reflection on the tongue surface caused by direct light;

[0047] A camera 4 is provided inside the tongue image acquisition device and is used to acquire tongue images. The camera 4 has high-definition imaging capabilities and is equipped with an aperture adjustment and a filter to ensure that the image brightness is moderate and the color is accurate;

[0048] As can be seen from the above, the camera device 4 in the tongue diagnosis instrument is mainly responsible for collecting and processing the patient's tongue image. The camera can be one or more. When working, the fixed light source needs to cooperate with the camera to ensure that the color of the collected image is as standard and uniform as possible;

[0049] The camera works as follows:

[0050] The device's lens first focuses and captures light from the tongue, adjusting the amount of incoming light through the aperture to ensure moderate image brightness. Meanwhile, the filter removes unnecessary infrared light to improve the color accuracy of the image. These light signals are then received by an image sensor (such as a CMOS or CCD) and converted into electrical signals. The sensor converts the light signals into processable electrical signals through line-by-line reading or charge transfer. These electrical signals are amplified and filtered to remove noise and enhance signal quality. Subsequently, an analog-to-digital converter converts the analog signals into digital signals for further digital processing. In the digital signal processing stage, denoising algorithms such as median filtering and Gaussian filtering are used to remove noise from the image, while color correction adjusts the image's color temperature, contrast, and saturation to ensure the color of the tongue is accurate. Finally, the image is converted into a common format, such as JPEG or PNG, for easy storage and transmission.

[0051] The processed image data is temporarily stored in the buffer area of ​​the control circuit and then transmitted to the control circuit or external device through a data interface (such as SPI, I2C or USB) for more in-depth study and recording.

[0052] A millimeter-wave radar module 9 is installed on the tongue image acquisition device to monitor the patient's physiological signs;

[0053] As can be seen from the above, the millimeter wave radar module 9 is installed in an appropriate position of the tongue diagnosis instrument, such as near the chest or abdomen when the patient is sitting, to ensure that physiological signs such as heartbeat and breathing can be accurately monitored;

[0054] The working principle of millimeter wave radar is as follows:

[0055] First, the radar transmits millimeter-wave signals in a specific frequency band (e.g., 60 GHz). When these signals encounter the target (e.g., the human chest), they generate reflected electromagnetic waves. The reflected signals are demodulated with the transmitted signals and then processed through a series of signal processing steps, including amplification, filtering, and analog-to-digital conversion (ADC), to obtain echo demodulated signal data. The microcontroller unit (MCU) accurately calculates the amplitude, frequency, and phase of these echo signals, thereby achieving measurement of target parameters (including sleep quality, breathing, turning over, body movement, etc.) and scene assessment.

[0056] Specifically, the radar transmits a linear frequency modulated continuous wave in the frequency band of 57.5 to 63.5 GHz to collect radar echoes reflected from the surface of the human chest. These echoes are sampled after mixing and low-pass filtering to obtain intermediate frequency sampling data containing respiratory and heartbeat micro-motion information. By performing fast Fourier transform (FFT) on these intermediate frequency sampling data, the radial distance of the human chest relative to the radar can be determined, and the phase signal corresponding to the chest position can be further extracted. In order to improve the accuracy and reliability of the signal, an improved phase difference enhancement method is used to suppress the interference of respiratory harmonics in the phase signal on the extraction of heartbeat signals, as well as the interference of low-frequency noise on the extraction of respiratory signals. Finally, a Gaussian smoothing filter method is used to extract a respiratory signal without waveform distortion from the phase signal, and a low-order finite impulse response (FIR) filter is used to extract a heartbeat signal without rate distortion from the phase signal. In addition, a time domain peak search algorithm is used to analyze the respiratory and heartbeat signals to calculate the accurate respiratory rate and heart rate. The millimeter wave radar workflow is shown in the figure below. Figure 2 As shown;

[0057] It should be noted that the millimeter wave radar module 9 is installed at an appropriate position of the tongue diagnosis instrument, such as the base of the tongue diagnosis instrument, near the chest or abdomen when the patient is sitting, so as to ensure accurate monitoring of physiological signs such as heartbeat and breathing;

[0058] The millimeter wave radar interface is set up by designing a matching interface circuit according to the communication method of the millimeter wave radar module, such as SPI, I2C or UART, to ensure that the built-in computer motherboard 11 can accurately read the respiratory and heart rate data output by the radar module.

[0059] A heat dissipation copper plate 7 is provided inside the tongue image acquisition device and is used to dissipate heat generated by the LED light source, the camera device 4, and the power transformer 10;

[0060] Computer motherboard 11, used to control the operation of the camera device 4 and the millimeter wave radar module 9, and process the collected data;

[0061] Specifically, the processed image data is temporarily stored in the buffer area of ​​the built-in computer motherboard 11 and then transmitted to other external devices such as computers or mobile phones by using a data interface or wireless transmission for more in-depth research and recording;

[0062] It should be noted that the computer motherboard 11 may be selected from, for example, an i5-8250u processor, an 8GB hard drive, a 256GB solid-state drive, etc.;

[0063] The computer communication interface is set as: a communication interface designed for connecting a computer to an external display device, such as an HDMI interface. The HDMI interface can be plug-and-play, facilitating data transmission;

[0064] Through the above settings, the computer motherboard 11 has multiple I / O interfaces that can be used to connect to devices such as cameras and millimeter-wave radars, and has sufficient processing power to control the data acquisition process.

[0065] A face shield 1 is made of sponge material and is used to reduce the discomfort of the person being photographed during the acquisition process;

[0066] The outer shell assembly, the elliptical inner shell 5, the soft light cover 3, the camera device 4, the millimeter wave radar module 9, the heat dissipation copper plate 7, and the face baffle 1 are fixed and connected by screws or plastic adhesives to ensure the structural stability of the device.

[0067] The present invention further specifically describes that the camera device 4 also includes an image processing module, which adopts an image enhancement algorithm. The image enhancement algorithm is used to pre-process the collected tongue image by denoising, color correction and edge enhancement to improve image quality and diagnostic accuracy. The millimeter wave radar module 9 also includes an environmental perception module for real-time monitoring of changes in the surrounding environment, such as temperature, humidity, and human movement, and automatically adjusting radar parameters according to environmental changes to improve monitoring accuracy and stability.

[0068] It should be noted that the power supply of this device is designed to provide stable and reliable power for each module of the tongue diagnosis instrument. The power management circuit is designed to ensure that the camera, millimeter wave radar, computer motherboard 11, etc. can obtain appropriate voltage and current when working. An external power adapter can be used for power supply, and voltage stabilization, filtering and other links are added to the circuit to ensure power quality. The internal connection structure diagram is shown in the figure. Figure 3 shown.

[0069] The present invention further specifically describes that the tongue image collection device also includes software development of the computer motherboard 11, and the software development of the computer motherboard 11 includes:

[0070] An initialization program for configuring the parameters of the camera device 4 and the millimeter-wave radar module 9 to put the device into a standby state. The parameters of the millimeter-wave radar module 9 are resolution, frame rate, and detection mode.

[0071] It should be noted that after the built-in computer motherboard 11 is powered on or reset, an initialization program is executed to configure the parameters of each interface, such as the resolution and frame rate of the camera, the detection mode of the millimeter wave radar, etc., so that the device enters the standby state and is ready to receive acquisition instructions;

[0072] A data acquisition control program is used to detect the acquisition status in real time, trigger the camera device 4 to capture tongue images, and activate the millimeter-wave radar module 9 to collect physiological sign data. The data acquisition control program has a data synchronization function and must be controlled within the same time period to ensure that the data collected by the camera device and the millimeter-wave radar module are consistent on the time axis.

[0073] As can be seen from the above, since there may be delays in data transmission, it is necessary to set up a data cache area inside the computer motherboard to temporarily store the collected image data and respiratory heart rate data in the cache area.

[0074] A data upload program, which uses a data transmission protocol and compression algorithm to quickly upload the collected image data and physiological sign data to a computer or cloud server;

[0075] As can be seen from the above, the image data and respiratory heart rate data in the buffer area are packaged in a certain format, such as adding data header, data length, check code and other information, and then the data packet is sent to the cloud through the wireless network. During the transmission process, the sub-packet transmission method can be used to improve the reliability of the transmission, and the integrity of the data is checked after each transmission. If there is an error, it is resent. The working process diagram of the computer motherboard 11 is shown as follows Figure 4 As shown;

[0076] In summary, by integrating the high-definition camera device 4 and the millimeter-wave radar module 9, the present invention can simultaneously collect tongue images and the patient's physiological sign data, realizing the synchronous collection of multimodal data and significantly improving the comprehensiveness and accuracy of data collection;

[0077] The aperture adjustment, optical filter, and image enhancement algorithm in the image processing module of the camera device 4 effectively reduce tongue reflections caused by direct light, improving image quality and diagnostic accuracy. The environmental perception function of the millimeter-wave radar module 9 can monitor changes in the surrounding environment in real time, such as temperature, humidity, and human movement, and automatically adjust radar parameters based on environmental changes, thereby improving monitoring accuracy and stability, allowing the acquisition device to maintain optimal working conditions in different environments.

[0078] The facial shield 1 is made of sponge material, which can reduce the discomfort of the person being photographed during the acquisition process and improve the user's comfort and acceptance; the data acquisition control program has a data synchronization function, which ensures that the data collected by the camera device 4 and the millimeter wave radar module 9 remain consistent on the timeline, providing doctors with more accurate and reliable diagnostic basis.

[0082] A data storage and management program, which uses a distributed storage architecture and efficient data indexing technology to classify, store, and manage received data; the data storage and management program provides data backup and recovery functions to ensure data security and reliability;

[0083] A data analysis and display program is developed on the tongue diagnosis instrument's computer motherboard to provide it with image data analysis capabilities. The data analysis and display program uses image processing and data analysis algorithms to extract and classify tongue image features from received image data; it also performs statistical analysis on physiological sign data and calculates parameters such as mean values ​​and standard deviations. The program can also intuitively display analysis results in the form of charts, reports, etc., providing doctors with comprehensive diagnostic references.

[0084] The present invention further specifically details that the data receiving program also has data integrity checking and error retransmission functions to ensure the integrity and accuracy of the received data.

The data analysis and display program also includes an intelligent diagnosis module. The intelligent diagnosis module is used to automatically provide preliminary diagnostic suggestions or early warning information based on tongue characteristics and physiological sign data, providing doctors with more convenient and efficient diagnostic support.

[0085] Through the above technical solution, the data storage and management program adopts a distributed storage architecture and efficient data indexing technology, which not only improves the efficiency of data storage and management, but also provides data backup and recovery functions, ensuring data security and reliability. At the same time, the program also provides data access permission control and data encryption functions, effectively protecting patients' privacy and data security.

[0086] The intelligent diagnosis module in the data analysis and presentation program can automatically provide preliminary diagnostic suggestions or early warning information based on tongue characteristics and physiological sign data, providing doctors with more convenient and efficient diagnostic support. This not only improves the accuracy and efficiency of diagnosis, but also reduces the workload of doctors.

[0087] This invention combines modern scientific and technological means with traditional Chinese medicine tongue diagnosis, promoting the modernization and intelligent development of Chinese medicine diagnostic technology. By collecting and analyzing multimodal data, it provides a more objective and scientific basis for Chinese medicine diagnosis, helping to improve the overall diagnosis and treatment level and competitiveness of Chinese medicine.
