Description

Technical Field

[0001] This invention relates to the field of beauty technology, and in particular to a beauty device and method based on thermal infrared analysis. Background Technology

[0002] In the current booming development of the beauty industry, consumers have put forward increasingly stringent requirements for the quality, efficiency and personalization of beauty services. However, traditional beauty equipment and service models have exposed many insurmountable problems, which seriously restrict the further development of the industry.

[0003] From an equipment perspective, traditional beauty instruments generally integrate detection and treatment functions into one unit. Technically, this integrated design makes it difficult to achieve simultaneous detection and treatment in the device's operational logic. For example, with a common instrument combining thermal infrared detection and phototherapy, when the phototherapy program is initiated, its internal circuitry, optical components, and software algorithms are all fully dedicated to the treatment process, leaving the thermal infrared detection module unable to operate simultaneously. In actual beauty salon operations, this limitation is amplified during peak customer traffic. Imagine a beauty salon experiencing a large influx of customers on a weekend. If an integrated beauty instrument is performing a 30-minute phototherapy treatment on one customer, other customers requiring testing must wait, resulting in the thermal infrared scanner and its associated data processing and analysis terminal being idle for an extended period, significantly reducing equipment utilization. This not only prevents the full utilization of the significant initial investment in equipment but also severely impacts the beauty salon's capacity, leading to a substantial decrease in service efficiency and, to some extent, the loss of potential customers.

[0004] Focusing on the beauty service process, beauticians face extremely complex situations in their daily work. Human skin types are diverse, including oily, dry, combination, and sensitive skin, and each customer's beauty needs are different. Some seek firmer skin, others desire to improve dull skin tone, and still others want to solve frequent acne breakouts. However, when faced with numerous customers, beauticians are limited by their energy and professional knowledge, making it difficult to tailor precise and personalized beauty plans for each client. In actual operation of beauty devices, they often have to use general operating parameters and procedures. From a skin physiology perspective, customers with dry, dehydrated skin may have a stratum corneum moisture content of less than 10%, and their skin barrier function is impaired, requiring high-frequency, low-intensity hydration treatments. Conversely, customers with excessive sebum secretion may require low-frequency, high-intensity oil control cleansing and sebaceous gland regulation. However, in the traditional model, both types of customers may use the same frequency and intensity of beauty device operation, such as setting ultrasonic iontophoresis devices to medium frequency and intensity. This clearly fails to meet the needs of different skin conditions, resulting in significantly reduced beauty effects and lower customer satisfaction. To ensure the accuracy of each client's medical records, testing is required before each cosmetic procedure. This process typically takes time, further extending the entire cosmetic service cycle, increasing time costs, reducing the operational efficiency of beauty salons, and limiting the number of customers a salon can serve per unit of time, which seriously hinders business expansion.

[0005] In conclusion, with the increasingly fierce competition in the beauty market, the shortcomings of traditional beauty equipment and service models in terms of efficiency, precision, and personalization have become more and more prominent, and they can no longer meet the urgent needs of beauty salons to improve service quality and enhance market competitiveness. Summary of the Invention

[0006] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0007] A beauty device based on thermal infrared analysis includes a thermal infrared scanner, a data processing and analysis terminal, a beauty parameter storage card, and a beauty instrument, wherein:

[0008] Thermal infrared scanners are used to scan the faces of cosmetic medical personnel, generate thermal infrared images, and send them to a data processing and analysis terminal.

[0009] The data processing and analysis terminal is equipped with a processor and integrated storage, imaging analysis, data analysis, and working parameter generation modules. The processor has several data transmission interfaces, through which the thermal infrared scanner and the beauty parameter storage card interact with the processor. Specifically, the processor uses the thermal infrared images acquired by the thermal infrared scanner to obtain beauty medical parameters through the imaging analysis module, stores the beauty patient's condition information in the storage module, and then uses the working parameter generation module to determine the required type of beauty device and its working parameters based on the beauty medical parameters, generating corresponding data and sending it to the beauty parameter storage card. The processor uses the data analysis module to perform longitudinal comparative analysis of multiple sets of historical beauty data from the same customer to generate skin condition development trends.

[0010] The beauty parameter storage card is used to insert into the data processing and analysis terminal to obtain the corresponding data, and it is also used to insert into the beauty device to send the corresponding data to the beauty device.

[0011] The beauty device reads data from the beauty parameter storage card and pairs with the device type data. If the beauty device type data is successfully paired, it reads the working parameter data from the beauty parameter storage card to drive the beauty treatment on the face of the medical professional. If the beauty device type data pairing fails, a warning is issued.

[0012] Preferably, the beauty device includes an ultrasonic beauty device, a microcurrent beauty device, and a photon skin rejuvenation beauty device.

[0013] Preferably, the cosmetic information stored in the storage module includes basic information of the cosmetic medical personnel, past cosmetic medical parameters, treatment effect records, and scan time.

[0014] Preferably, the imaging analysis module includes:

[0015] The image preprocessing unit is used to perform noise reduction processing on the thermal infrared images sent by the thermal infrared scanner, remove noise in the images, and at the same time perform contrast enhancement processing on the images to make the skin texture and temperature difference features in the images clear and distinguishable.

[0016] The feature extraction unit uses an edge detection algorithm to extract the edge contour of the skin in thermal infrared imaging; it uses a threshold segmentation algorithm to segment different temperature regions in thermal infrared imaging; and it obtains skin temperature distribution features and blood vessel morphology features by calculating the gray value statistical features and texture features of different regions in the image.

[0017] The parameter calculation unit, based on the extracted features and combined with the preset skin physiological model, obtains the skin's moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation status.

[0018] Preferably, the parameter calculation unit calculates the skin's moisture content by analyzing the relationship between skin surface temperature and water evaporation in thermal infrared imaging; the parameter calculation unit derives the skin's oil secretion status through a correlation model between skin temperature and oil secretion in a specific area; the parameter calculation unit calculates collagen content by the correspondence between temperature change characteristics of elastic areas of the skin in thermal infrared imaging and collagen content; the parameter calculation unit calculates skin elasticity by the characteristics of temperature change when the skin is subjected to slight pressure in thermal infrared imaging; and the parameter calculation unit calculates blood circulation status by detecting changes in heat flux in specific areas of the skin in thermal infrared imaging.

[0019] Preferably, the working parameter generation module includes:

[0020] The beauty device type determination unit has a built-in beauty device adaptation rule library, which stores the correspondence between different combinations of beauty and medical parameters and beauty device types. After obtaining the beauty and medical parameters, it comprehensively analyzes the parameters of skin moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation. If the analysis shows that the skin moisture content is low and sebum secretion is normal, it is preferentially determined that an ultrasonic beauty device is suitable; if the analysis shows that the skin sebum secretion is excessive and elasticity is poor, it is preferentially determined that a microcurrent beauty device is suitable; if the analysis shows that the skin tone is dull and there are pigmentation problems, it is preferentially determined that a photon skin rejuvenation beauty device is suitable. Moreover, when multiple parameters meet the applicable conditions of different beauty devices, the determination is made according to the preset priority order.

[0021] The moisture parameter generation unit generates higher infusion frequency parameters and longer working time parameters when it determines that an ultrasonic beauty device is being used and the skin moisture content is lower than a preset threshold, in order to enhance the moisturizing effect; when it determines that a photon skin rejuvenation beauty device is being used and the skin moisture content is low, it generates low energy and multiple irradiation parameters to promote skin water circulation.

[0022] The sebum parameter generation unit generates high-intensity, low-frequency current parameters to regulate sebum secretion when a microcurrent beauty device is used and the condition is characterized by excessive sebum secretion; and generates high-energy, short-duration, single-session irradiation parameters to inhibit sebum secretion when a photon skin rejuvenation beauty device is used and the condition is characterized by excessive sebum secretion.

[0023] The collagen parameter generation unit generates pulse current parameters of specific frequency and intensity when it determines that a microcurrent beauty device is being used and the collagen content is low, thereby stimulating collagen regeneration; and generates specific vibration frequency and intensity parameters when it determines that an ultrasonic beauty device is being used and the collagen content is insufficient, thereby promoting collagen synthesis.

[0024] The elasticity parameter generation unit determines that if a microcurrent beauty device is used and the skin elasticity is poor, it generates a gradually increasing current parameter to enhance muscle contraction and improve elasticity; if an ultrasonic beauty device is used and the skin elasticity is poor, it generates specific waveform and frequency parameters to improve skin elasticity.

[0025] The blood circulation parameter generation unit generates current parameters with specific waveforms to promote blood circulation when it determines that a microcurrent beauty device is being used and poor blood circulation is detected; when it determines that an ultrasound-guided beauty device is being used and blood circulation is insufficient, it generates specific thermal effect parameters to accelerate blood circulation.

[0026] Preferably, the data analysis module includes:

[0027] The data integration unit is used to integrate multiple sets of historical beauty data of the same customer in the storage module, including thermal infrared imaging, beauty medical parameters, treatment effect records, etc. from different periods, and arrange them in chronological order.

[0028] The comparative analysis unit performs a longitudinal comparison of the integrated data to analyze the changing trends of various skin parameters at different times.

[0029] The trend prediction unit, based on the results of comparative analysis, uses time series analysis algorithms to predict the future development trend of skin condition and generate a skin condition development trend report.

[0030] Preferably, the beauty device also includes:

[0031] The data reading module is used to read data from the inserted beauty parameter storage card, including beauty device type data and working parameter data;

[0032] The type matching module matches the read beauty device type data with its own preset beauty device type to determine if they match. If the match is successful, it sends a start signal to the working parameter execution module; if the match is unsuccessful, it sends a trigger signal to the alarm module.

[0033] After receiving the start signal from the type matching module, the working parameter execution module drives the corresponding functional components of the beauty instrument to work according to the read working parameter data, so as to perform beauty treatment on the face of the medical beauty personnel.

[0034] The alarm module, upon receiving a trigger signal from the type pairing module, issues an audible and visual alarm to remind the beautician that the beauty device type data pairing has failed.

[0035] Preferably, the data processing and analysis terminal also includes a display module, which displays the type of beauty device in real time after the working parameter generation module determines the required type of beauty device.

[0036] A beauty method based on the aforementioned beauty device using thermal infrared analysis includes the following steps:

[0037] Initial cosmetic treatment steps: A thermal infrared scanner scans the face of the cosmetic medical practitioner, generating a thermal infrared image and sending it to a data processing and analysis terminal. The processor of the data processing and analysis terminal obtains the cosmetic medical parameters through the imaging analysis module, stores the cosmetic medical practitioner's cosmetic condition information through the storage module, and then determines the required type of beauty device and its working parameters based on the cosmetic medical parameters through the working parameter generation module, sending the data to the beauty parameter storage card. The beauty parameter storage card is inserted into the beauty device, and the beauty device reads the data. If the beauty device type data is successfully matched, the cosmetic treatment is performed on the face of the cosmetic medical practitioner according to the working parameter data. If the beauty device type data is not successfully matched, a warning is issued and the beauty device is replaced.

[0038] Subsequent cosmetic treatment steps: The processor of the data processing and analysis terminal performs longitudinal comparative analysis on multiple sets of historical cosmetic data of the same customer through the data analysis module to generate skin condition development trends; if no adjustment to the treatment plan is required, the cosmetic medical personnel's cosmetic condition information is directly retrieved from the storage module, the working parameter data is sent to the cosmetic parameter storage card, the card is inserted into the beauty device for treatment; if the treatment plan needs to be adjusted, the thermal infrared scanner is restarted to scan the face, the data processing and analysis process in the initial cosmetic treatment steps is repeated, the beauty device type and its working parameters are updated, and then treatment is performed.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] By separating the detection and treatment functions into independent modules, the thermal infrared scanner and data processing and analysis terminal can serve other customers simultaneously while the beauty device is being used for treatment. For example, during peak hours on weekends, traditional equipment may have its detection function idle due to treatments occupying the space. This device can enable multiple groups of customers to undergo detection and treatment at the same time, significantly improving equipment utilization efficiency, avoiding waste of equipment resources, reducing equipment costs for beauty salons, enhancing reception capacity and service efficiency, reducing customer waiting time, increasing customer satisfaction, and enhancing the market competitiveness of beauty salons.

[0041] Addressing the issues of inconsistent beauty solutions and lack of personalized treatment in traditional beauty services, this device uses a thermal infrared scanner and data processing and analysis terminal to accurately acquire various beauty and medical parameters of the customer's skin, such as moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation. Based on these parameters and a beauty device adaptation rule library, the working parameter generation module tailors the appropriate beauty device type and its working parameters for each customer. This achieves truly personalized beauty treatments, significantly improving beauty results and increasing customer satisfaction.

[0042] By integrating, analyzing, and predicting trends in customers' historical beauty data through a data processing and analysis terminal, it is possible to quickly determine whether the treatment plan needs adjustment during subsequent beauty treatments. If no adjustment is needed, the parameters can be directly retrieved for treatment, reducing unnecessary testing steps and shortening the beauty service cycle. If adjustment is required, it can also determine the new beauty device type and operating parameters more accurately and efficiently based on historical and real-time testing data. At the same time, the beauty device type display function and intelligent alarm function reduce beautician operation errors, improve operational accuracy and efficiency, optimize the overall beauty service process, reduce time costs, increase the number of customers served by the beauty salon per unit time, and promote business expansion.

Detailed Implementation

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-4 In this embodiment of the invention, a beauty device based on thermal infrared analysis comprises a thermal infrared scanner 10, a data processing and analysis terminal 20, a beauty parameter storage card 30, and a beauty instrument 40. The thermal infrared scanner 10 is based on thermal radiation imaging technology, which captures thermal radiation signals from the skin surface, converts them into thermal infrared images, and quickly transmits them to the data processing and analysis terminal 20. This detection design can directly provide scanning services for multiple customers without being limited by the time constraints of customer beauty treatments, greatly improving the efficiency of the device.

[0053] The data processing and analysis terminal 20 integrates multiple functional modules. The processor 21 coordinates the work of each module and interacts with the thermal infrared scanner 10 and the beauty parameter storage card 30 via the data transmission interface 26. The storage module 25 is used to store various data of beauty medical personnel for long-term preservation, providing historical evidence for subsequent analysis and treatment. The imaging analysis module 22 processes thermal infrared images, converting them into beauty medical parameters. The working parameter generation module 24 determines the appropriate type of beauty instrument 40 and its working parameters based on these parameters. The data analysis module 23 predicts skin condition trends through analysis of historical data. The display module 27 intuitively displays the type of beauty instrument 40, assisting beauticians in selecting the corresponding beauty instrument 40.

[0054] The beauty parameter storage card 30 can conveniently transfer data between the data processing and analysis terminal 20 and the beauty device 40. After the data processing and analysis terminal 20 completes the parameter calculation and determines the type and working parameters of the beauty device 40, the beauty parameter storage card 30 stores and transmits this data to the beauty device 40 to ensure that the beauty device 40 obtains accurate working instructions.

[0055] As a device that acts directly on the customer's face, the beauty device 40 performs beauty treatments based on the received data. Different types of beauty devices 40, such as ultrasonic beauty devices 40, microcurrent beauty devices 40, and photon skin rejuvenation beauty devices 40, achieve targeted skin care through their unique physical or optical principles.

[0056] The data processing and analysis terminal 20 described above includes the following functional modules:

[0057] Imaging Analysis Module 22: The imaging analysis module 22 consists of an image preprocessing unit 221, a feature extraction unit 222, and a parameter calculation unit 223. The image preprocessing unit 221 first performs noise reduction processing on the thermal infrared imaging to remove noise generated by environmental interference or the device itself during the imaging process. Then, it enhances the image contrast through existing algorithms such as histogram equalization, making details such as skin texture and temperature differences clearer, and providing high-quality image data for subsequent feature extraction.

[0058] The feature extraction unit 222 employs edge detection algorithms, such as the Canny algorithm. The Canny algorithm is an edge detection algorithm widely used in computer vision and image processing. It can accurately extract the edge contour of the skin, providing key information for subsequent skin condition assessment. Using the Canny algorithm, the edge contour of the skin is accurately delineated. The threshold segmentation algorithm is used to separate different temperature regions. By calculating gray value statistical features and texture features, such as gray-level co-occurrence matrix features, key information such as skin temperature distribution features and blood vessel morphology features is obtained. These features are important basis for assessing skin condition.

[0059] The parameter calculation unit 223 analyzes the extracted features in conjunction with a preset skin physiological model; calculates the skin's moisture content by analyzing the relationship between skin surface temperature and water evaporation in thermal infrared imaging; derives the oil secretion status based on a correlation model between skin temperature and oil secretion in a specific area; calculates the collagen content by referring to the correspondence between temperature change characteristics of skin elastic areas and collagen content; calculates skin elasticity by utilizing the temperature change characteristics of skin under slight pressure; and calculates blood circulation status by detecting changes in heat flux in specific areas of the skin, thereby obtaining comprehensive cosmetic medical parameters.

[0060] Working Parameter Generation Module 24: The working parameter generation module 24 is used for the collaborative work of the beauty device type determination unit 241 and various parameter generation units. The beauty device type determination unit 241 has a built-in beauty device 40 adaptation rule library. This rule library is based on a large amount of clinical practice and skin physiology research, and establishes a correspondence between different combinations of beauty medical parameters and beauty device 40 types. After obtaining the beauty medical parameters, this unit comprehensively analyzes parameters such as skin moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation. According to the rules in the rule library, it prioritizes matching the most suitable beauty device 40 type for the customer. For example, for customers with dry and dehydrated skin, the ultrasonic infusion beauty device 40 with highly efficient moisturizing function is preferred; for customers with loose and inelastic skin, the microcurrent beauty device 40 is recommended to stimulate muscle contraction and improve skin firmness. After determining the type of beauty device 40, each parameter generation unit generates corresponding working parameters based on the skin condition and the type of beauty device 40. For example, the moisture parameter generation unit 242 generates parameters for higher infusion frequency and longer working time for the ultrasonic infusion beauty device 40 to enhance the moisturizing effect, and generates parameters for low energy and multiple irradiations for the photon skin rejuvenation beauty device 40 to promote skin water circulation. Similarly, the oil parameter generation unit 243 generates high-intensity, low-frequency current parameters for the microcurrent beauty device 40 to regulate sebum secretion, and generates parameters for high energy and short-duration single irradiations for the photon skin rejuvenation beauty device 40 to inhibit oil secretion. Other parameter generation units follow the same principle to ensure that the beauty device 40 provides personalized beauty treatments to customers in optimal working condition.

[0061] Data Analysis Module 23: Through data integration unit 231, comparative analysis unit 232, and trend prediction unit 233, data analysis module 23 achieves in-depth mining and utilization of customer beauty data. Data integration unit 231 integrates multiple sets of historical beauty data of the same customer in storage module 25, including thermal infrared imaging, beauty medical parameters, treatment effect records, etc. from different periods, in chronological order to form a complete personal beauty data archive;

[0062] The comparative analysis unit 232 performs longitudinal comparisons of the integrated data, providing a detailed analysis of the changing trends of various skin parameters at different times. For example, it compares the changes in skin moisture content before and after multiple treatments, observes fluctuations in sebum secretion in different seasons or treatment stages, understands the increasing or decreasing trends of collagen content over time, analyzes the degree of improvement in skin elasticity during treatment, and monitors changes in blood circulation. Through these comparative analyses, the effectiveness of past cosmetic treatments can be intuitively assessed.

[0063] The trend prediction unit 233, based on the results of comparative analysis, uses time series analysis algorithms, such as the existing ARIMA model. ARIMA, short for Autoregressive Integral Moving Average, is a commonly used predictive model in time series analysis. In your provided beauty equipment technical solution, it is mainly used to predict the future development trend of skin condition. Using the ARIMA model, the future development trend of skin condition is predicted, and a skin condition trend report is generated based on the prediction results, providing a scientific basis for adjusting subsequent beauty treatment plans. For example, if it is predicted that the collagen content of the customer's skin will continue to decline, the treatment plan can be adjusted in advance, adding treatments that stimulate collagen regeneration or adjusting the operating parameters of the beauty device 40.

[0064] Storage Module 25: Storage Module 25 serves as the data warehouse for the entire device, storing basic information about cosmetic medical personnel, such as name, age, gender, and contact information. This information helps establish customer profiles, facilitating customer management and service tracking for beauty salons. Simultaneously, Storage Module 25 also saves past cosmetic medical parameters, including data on skin moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation obtained from each test, providing rich historical data resources for Data Analysis Module 23. Furthermore, treatment effect records and scan times are also stored. Comprehensive analysis of this data allows for a complete understanding of the customer's cosmetic journey and treatment results, providing strong support for developing personalized cosmetic plans.

[0065] Display Module 27: The display module 27 is designed with the ease of use of beauticians in mind. After the working parameter generation module 24 determines the required type of beauty device 40, the display module 27 displays the type of beauty device 40 in a clear and intuitive manner in real time. This function effectively reduces the possibility of beauticians picking the wrong beauty device 40 due to negligence or misjudgment, thus improving the accuracy and efficiency of beauty operations. For example, when the display module 27 displays "Ultrasound induction beauty device 40", the beautician can quickly select the corresponding instrument from the equipment, avoiding affecting the beauty treatment effect or wasting time due to selecting the wrong instrument.

[0066] In the aforementioned beauty device 40 functional modules, the data reading module 41 serves as the data receiving entry point, enabling it to quickly and accurately read data from the inserted beauty parameter storage card 30, including beauty device 40 type data and working parameter data. This data serves as the basis for the instructions for the beauty device 40 to operate.

[0067] The type matching module 42 matches the type data of the beauty device 40 it reads with its own preset type of beauty device 40. If the two match, it means that the beauty device 40 matches the instrument type determined by the data processing and analysis terminal 20, and the type matching module 42 sends a start signal to the working parameter execution module 43. If the matching fails, it means that the beauty device 40 is selected incorrectly, and the type matching module 42 sends a trigger signal to the alarm module 44. This strict type matching mechanism effectively avoids the risk of using the wrong instrument for treatment.

[0068] After receiving the start signal from the type matching module 42, the working parameter execution module 43 drives the corresponding functional components of the beauty device 40 to operate according to the read working parameter data. For example, for the ultrasonic beauty device 40, the working parameter execution module 43 adjusts the frequency, intensity, and working time of the ultrasonic waves according to the working parameter data to better deliver beauty products into the deeper layers of the skin; for the microcurrent beauty device 40, it adjusts the intensity, frequency, and waveform of the current to stimulate skin muscle contraction, thereby improving skin firmness.

[0069] Upon receiving the trigger signal from the type matching module 42, the alarm module 44 immediately issues an audible and visual alarm. Through sound prompts and flashing lights, it quickly attracts the attention of the beautician, reminding them that the type data matching of the beauty device 40 has failed and that the beauty device 40 needs to be replaced promptly, thereby ensuring the safety and effectiveness of the beauty treatment process.

[0070] like Figure 3-4 As shown, based on the above technical solution, the specific beauty process method includes the following steps:

[0071] Step 1, Equipment Initialization: In the actual operation scenario of a beauty salon, the thermal infrared scanner 10, data processing and analysis terminal 20, beauty parameter storage card 30, and beauty device 40 are arranged and connected in a reasonable manner. The data processing and analysis terminal 20 is initialized. The beauty device type determination unit 241 of the working parameter generation module 24 is entered and improved to ensure that it contains the accurate correspondence between different combinations of beauty and medical parameters and the type of beauty device 40. A suitable time series analysis algorithm is preset in the trend prediction unit 233 of the data analysis module 23. At the same time, the display format and content are set in the display module 27 of the data processing and analysis terminal 20 to clearly present the type of beauty device 40.

[0072] Step 1, Initial Cosmetic Treatment Process: When a cosmetic medical professional visits the store for the first time, the staff guides the customer to the thermal infrared scanner 10, keeps the customer still and keeps the face at a suitable distance from the scanner lens, and controls the temperature and humidity of the scanning environment within a preset range. The thermal infrared scanner 10 is activated to scan the customer's face, generate thermal infrared images, and quickly sends the images to the data processing and analysis terminal 20 through the data transmission interface 26.

[0073] The imaging analysis module 22 of the data processing and analysis terminal 20 begins operation. The image preprocessing unit 221 first performs noise reduction processing on the thermal infrared image to remove noise points, and then uses a histogram equalization algorithm to enhance image contrast, making features such as skin texture and temperature differences clearly distinguishable. Next, the feature extraction unit 222 uses an edge detection algorithm to extract the skin edge contour, uses a threshold segmentation algorithm to segment different temperature regions, and calculates the gray value statistical features and texture features of different regions of the image to obtain skin temperature distribution features and blood vessel morphology features. Finally, the parameter calculation unit 223 calculates cosmetic medical parameters such as skin moisture content, sebum secretion, collagen content, skin elasticity, and blood circulation based on the extracted features and a preset skin physiological model.

[0074] The processor 21 stores the acquired cosmetic medical parameters through the storage module 25, recording the cosmetic medical personnel's cosmetic condition information; subsequently, the working parameter generation module 24 starts working based on the cosmetic medical parameters, and the beauty instrument type determination unit 241 comprehensively analyzes the various parameters and, according to the rules of the beauty instrument 40 adaptation rule library, prioritizes determining the required beauty instrument 40 type; after determining the beauty instrument 40 type, each parameter generation unit generates suitable working parameters based on the determined beauty instrument 40 type and skin condition;

[0075] The generated data is sent to the beauty parameter storage card 30, and the beautician inserts the storage card into the beauty device 40. The data reading module 41 of the beauty device 40 reads the data from the storage card, and the type matching module 42 matches the read beauty device 40 type data with its own preset beauty device 40 type. If the match is successful, the working parameter execution module 43 drives the corresponding functional components of the beauty device 40 to perform beauty treatment on the customer's face according to the read working parameter data. If the match is unsuccessful, the alarm module 44 issues an audible and visual alarm to remind the beautician to replace the beauty device 40.

[0076] Step 1, Subsequent Beauty Treatment Process: When the customer returns for subsequent beauty treatments, the data analysis module 23 of the data processing and analysis terminal 20 first integrates multiple sets of historical beauty data of the customer in the storage module 25 and arranges them in chronological order; the comparison and analysis unit 232 performs a longitudinal comparison of the integrated data and analyzes in detail the changing trends of various skin parameters at different times; based on the results of the comparison and analysis, the trend prediction unit 233 uses a preset time series analysis algorithm to predict the future development trend of the skin condition and generates a skin condition development trend report; if the report indicates that no adjustment to the treatment plan is required, the customer's beauty condition information is directly retrieved from the storage module 25, and the working parameter data is sent to the beauty parameter storage card 30, which the customer inserts into the beauty device 40 for treatment; if the treatment plan needs to be adjusted, the thermal infrared scanner 10 is restarted to scan the customer's face, the data processing and analysis process in the initial beauty treatment steps is repeated, the type of beauty device 40 and its working parameters are updated, and then treatment is performed.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
