Description

Technical Field

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

[0002] As the beauty industry is booming, consumers are placing increasingly stringent demands on the quality, efficiency, and personalization of beauty services. However, traditional beauty equipment and service models have exposed many difficult-to-overcome problems, seriously restricting the further development of the industry.

[0003] From a device perspective, previous beauty devices generally integrated detection and treatment functions into one device. Technically, this integrated design made it difficult to achieve simultaneous detection and treatment. For example, when a device with both thermal infrared detection and photorejuvenation functions initiates a photorejuvenation treatment, its internal circuitry, optical components, and other hardware resources, as well as its software algorithms, are fully dedicated to the treatment process, preventing the thermal infrared detection module from operating simultaneously. In actual beauty salon operations, this limitation is exacerbated during peak customer traffic. For example, consider a beauty salon experiencing a large number of customers on a weekend. If an integrated beauty device is currently performing a 30-minute photorejuvenation treatment on a single client, other clients requiring testing are forced to wait. This results in the in-store thermal infrared scanner and its accompanying data processing and analysis terminal being idle for extended periods, significantly reducing equipment utilization. This not only hinders the full utilization of the substantial initial investment in equipment, but also severely impacts the salon's customer service capacity, significantly reducing service efficiency and, to a certain extent, causing potential customer loss.

[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. Each customer has unique beauty needs, ranging from firmer skin to improved dull complexion and a desire to address frequent acne. However, beauticians face challenges in tailoring precise, personalized beauty plans for each client due to limited time and expertise. When operating beauty devices, they often rely on generic operating parameters and procedures. From a skin physiology perspective, patients with dry, dehydrated skin may have a stratum corneum moisture content of less than 10%, impairing skin barrier function and requiring high-frequency, low-intensity hydration treatments. Patients with excessive oil secretion, however, may require low-frequency, high-intensity oil-control cleansing and sebaceous gland regulation. Traditionally, however, both types of skin may be operated with the same frequency and intensity beauty device, such as ultrasonic transdermal devices set to medium frequency and intensity. This clearly fails to meet the needs of different skin conditions, significantly compromising beauty results and reducing customer satisfaction. In order to ensure the medical accuracy of each customer, testing is required before each cosmetic treatment. This process usually takes a certain amount of time, further lengthening the entire cosmetic service cycle, increasing time costs, and reducing the operating efficiency of the beauty salon. This limits the number of customers that the beauty salon can serve per unit time, seriously hindering business expansion.

[0005] To sum up, with the increasingly fierce competition in the beauty market, the defects of traditional beauty equipment and service models in terms of efficiency, accuracy and personalization have become increasingly prominent, and can no longer meet the urgent needs of current beauty salons to improve service quality and enhance market competitiveness. Summary of the Invention

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

[0007] A beauty device based on thermal infrared analysis, comprising a thermal infrared scanner, a data processing and analysis terminal, a beauty parameter storage card, and a beauty instrument, wherein: Thermal infrared scanners are used to scan the faces of cosmetic medical personnel, generate thermal infrared images and send them to the data processing and analysis terminal; The data processing and analysis terminal is provided with a processor and a storage module integrated with the processor, an imaging analysis module, a data analysis module, and a working parameter generation module. The processor is provided with several data transmission interfaces, through which the thermal infrared scanner and the beauty parameter storage card respectively exchange data with the processor. The processor obtains beauty medical parameters through the imaging analysis module based on the thermal infrared imaging acquired by the thermal infrared scanner, and stores the beauty condition information of the beauty medical personnel through the storage module. The working parameter generation module then determines the type of beauty instrument required by the beauty medical personnel and its working parameters based on the beauty medical parameters, generates corresponding data, and sends it to the beauty parameter storage card. The processor uses the data analysis module to perform longitudinal comparative analysis on multiple sets of historical beauty data of the same customer to generate skin condition development trends. The beauty parameter storage card is used to be inserted into the data processing and analysis terminal to obtain corresponding data, and is also used to be inserted into the beauty instrument to send corresponding data to the beauty instrument; The beauty instrument is used to read the data from the beauty parameter storage card and perform pairing based on the beauty instrument type data. If the beauty instrument type data is paired successfully, it is driven by reading the working parameter data in the beauty parameter storage card to perform beauty treatment on the face of the beauty medical staff; if the beauty instrument type data is paired unsuccessfully, a warning is issued.

[0008] Preferably, the beauty device includes an ultrasonic infusion beauty device, a microcurrent beauty device and a photon rejuvenation beauty device.

After obtaining the beauty medical parameters, the unit comprehensively analyzes the skin's moisture content parameters, oil secretion parameters, collagen content parameters, skin elasticity parameters, and blood circulation parameters. If the analysis shows that the skin's moisture content is low and oil secretion is normal, the unit will prioritize the use of an ultrasonic induction beauty instrument. If the analysis shows that the skin's oil secretion is strong and its elasticity is poor, the unit will prioritize the use of a microcurrent beauty instrument. If the analysis shows that the skin has dull skin or pigmentation problems, the unit will prioritize the use of a photorejuvenation beauty instrument. When multiple parameters meet the applicable conditions of different beauty instruments, the unit will determine the appropriateness according to the preset priority order. The moisture parameter generation unit generates parameters for higher frequency and longer operating time to enhance the hydration effect when it determines that an ultrasonic infusion beauty device is being used and the skin moisture content is below a preset threshold. It also generates parameters for low energy and multiple irradiations to promote skin water circulation when it determines that a photorejuvenation beauty device is being used and the skin moisture content is low. The oil parameter generation unit generates high-intensity, low-frequency current parameters to regulate sebaceous gland secretion when a microcurrent beauty device is used and oil secretion is excessive. It also generates high-energy, short-duration single irradiation parameters to suppress oil secretion when a photorejuvenation beauty device is used and oil secretion is excessive. The collagen parameter generation unit generates pulse current parameters of specific frequency and intensity to stimulate collagen regeneration when a microcurrent beauty device is used and the collagen content is low. It also generates specific vibration frequency and intensity parameters to promote collagen synthesis when an ultrasonic infusion beauty device is used and the collagen content is insufficient. The elasticity parameter generation unit generates current parameters with gradually increasing intensity if it is determined that a microcurrent beauty device is used and the skin has poor elasticity, thereby enhancing muscle contraction and improving elasticity. If it is determined that an ultrasonic infusion beauty device is used and the skin has poor elasticity, it generates specific waveform and frequency parameters to improve skin elasticity. The blood circulation parameter generation unit generates current parameters with specific waveforms to promote blood circulation when it is determined that a microcurrent beauty device is used and poor blood circulation is detected; and generates specific thermal effect parameters to speed up blood circulation when it is determined that an ultrasonic induction beauty device is used and blood circulation is insufficient.

[0013] Preferably, the data analysis module includes: 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. at different periods, and arrange them in chronological order; The comparative analysis unit conducts longitudinal comparison of the integrated data and analyzes the changing trends of various skin parameters in different periods; The trend prediction unit, based on the results of comparative analysis, uses time series analysis algorithms to predict the future development trend of skin conditions and generate a skin condition development trend report.

[0014] Preferably, the beauty instrument further comprises: A data reading module is used to read the data in the inserted beauty parameter storage card, including the beauty instrument type data and working parameter data; The type matching module matches the read beauty instrument type data with its own preset beauty instrument type to determine whether they are consistent; 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; The working parameter execution module, after receiving the start signal from the type matching module, drives the corresponding functional components of the beauty instrument to work according to the read working parameter data, and performs beauty treatment on the face of the beauty medical staff; The alarm module, after receiving the trigger signal from the type matching module, issues an audible and visual alarm to remind the beautician that the beauty instrument type data matching is unsuccessful.

[0015] Preferably, the data processing and analysis terminal further comprises a display module, and after the working parameter generation module determines the required beauty instrument type, the display module displays the beauty instrument type in real time.

[0016] A beauty method based on the above-mentioned beauty device based on thermal infrared analysis comprises the following steps: Initial cosmetic treatment steps: A thermal infrared scanner scans the cosmetic practitioner's face, generates a thermal infrared image, and sends it to a data processing and analysis terminal. The processor of the data processing and analysis terminal obtains cosmetic medical parameters through an imaging analysis module, stores the cosmetic practitioner's cosmetic condition information through a storage module, and then determines the cosmetic medical device type and its operating parameters required by the cosmetic medical device based on the cosmetic medical parameters through an operating parameter generation module, and sends the data to a cosmetic parameter storage card. The cosmetic parameter storage card is inserted into the beauty device, which reads the data. If the beauty device type data is successfully matched, the cosmetic treatment is performed on the cosmetic practitioner's face based on the operating parameter data. If the beauty device type data is unsuccessful, a warning is issued and the beauty device is replaced. Subsequent beauty treatment steps: The processor of the data processing and analysis terminal conducts longitudinal comparative analysis on multiple sets of historical beauty data of the same customer through the data analysis module to generate skin condition development trends; if there is no need to adjust the treatment plan, directly retrieve the beauty condition information of the beauty medical staff from the storage module, send the working parameter data to the beauty parameter storage card, and insert the card into the beauty instrument for treatment; if the treatment plan needs to be adjusted, restart the thermal infrared scanner to scan the face, repeat the data processing and analysis process in the initial beauty treatment steps, and update the beauty instrument type and its working parameters before performing treatment.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 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 during the beauty instrument treatment. For example, on weekends when there is a large customer flow, traditional equipment may be idle due to treatment, while the detection function is idle. This device can realize simultaneous detection and treatment for multiple groups of customers, significantly improving equipment utilization efficiency, avoiding equipment resource waste, reducing equipment investment costs of beauty salons, improving reception capacity and service efficiency, reducing customer waiting time, improving customer satisfaction, and enhancing the market competitiveness of beauty salons. To address the uneven beauty solutions and lack of personalized treatment in traditional beauty services, a thermal infrared scanner and data processing and analysis terminal are used to accurately obtain a variety of beauty and medical parameters such as the customer's skin moisture content, oil secretion, collagen content, skin elasticity, and blood circulation. The operating parameter generation module uses these parameters, combined with a beauty instrument adaptation rule library, to tailor the appropriate beauty instrument type and operating parameters for each customer, achieving truly personalized beauty treatments, significantly improving beauty results, and increasing customer satisfaction. By integrating, analyzing and predicting the trends of customers' historical beauty data through the data processing and analysis terminal, it is possible to quickly determine whether the treatment plan needs to be adjusted in subsequent beauty treatments. If no adjustment is required, the parameters can be directly called up for treatment, reducing unnecessary testing steps and shortening the beauty service cycle. If adjustment is required, the new beauty instrument type and working parameters can be determined more accurately and efficiently based on historical data and real-time detection data. At the same time, the beauty instrument type display function and intelligent alarm function can reduce beautician's operating errors, improve operational accuracy and efficiency, optimize the overall beauty service process, reduce time costs, increase the number of customers served by beauty salons per unit time, and promote business expansion.

DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 In an embodiment of the present 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, based on thermal radiation imaging technology, 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 to multiple customers without being restricted by the time of the customer's beauty treatment, greatly improving the efficiency of the device. 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 cosmetic medical personnel over a long period of time, providing a historical basis for subsequent analysis and treatment. The imaging analysis module 22 processes thermal infrared images and converts them into cosmetic medical parameters. The operating parameter generation module 24 determines the appropriate type and operating parameters of the beauty device 40 based on these parameters. The data analysis module 23 predicts the development trend of skin conditions by analyzing historical data. The display module 27 intuitively displays the types of beauty devices 40, assisting beauticians in selecting the appropriate beauty device 40. The beauty parameter storage card 30 can conveniently transfer data between the data processing and analysis terminal 20 and the beauty instrument 40. After the data processing and analysis terminal 20 completes parameter calculation and determines the type and working parameters of the beauty instrument 40, the beauty parameter storage card 30 stores and transmits these data to the beauty instrument 40, ensuring that the beauty instrument 40 receives accurate working instructions. The beauty device 40 is a device that acts directly on the customer's face and performs beauty treatment based on the received data. Different types of beauty devices 40, such as ultrasonic introduction beauty devices 40, microcurrent beauty devices 40 and photon rejuvenation beauty devices 40, achieve targeted skin care through their own unique physical or optical principles.

[0024] The functional modules of the data processing and analysis terminal 20 include the following functional modules: 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 image to remove noise caused by environmental interference or the device itself during the imaging process. It then enhances the image contrast through existing algorithms such as histogram equalization, making details such as skin texture and temperature differences clearer, providing high-quality image data for subsequent feature extraction. The feature extraction unit 222 uses an edge detection algorithm, 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. The Canny algorithm is used to accurately outline the edge contour of the skin, and the threshold segmentation algorithm is used to separate different temperature areas. By calculating grayscale value statistical features and texture features, such as gray level co-occurrence matrix features, key information such as skin temperature distribution characteristics and blood vessel morphology characteristics are obtained. These features are important basis for assessing skin condition. The parameter calculation unit 223 analyzes the extracted features in combination with a preset skin physiological model; calculates the moisture content of the skin by analyzing the relationship between the skin surface temperature and water evaporation in thermal infrared imaging; derives the oil secretion situation based on a correlation model between the skin temperature and oil secretion in a specific area; calculates the collagen content by referring to the corresponding relationship between the temperature change characteristics and the collagen content in the elastic area of ​​the skin; calculates the skin elasticity by using the temperature change characteristics of the skin when it is subjected to slight pressure; and calculates the blood circulation status by detecting the heat flux changes in a specific area of ​​the skin, thereby obtaining comprehensive cosmetic and medical parameters.

[0025] Working Parameter Generation Module 24: Working Parameter Generation Module 24 is responsible for the coordinated operation of the beauty device type determination unit 241 and the various parameter generation units. The beauty device type determination unit 241 includes a built-in beauty device 40 adaptation rule base. This rule base, based on extensive clinical practice and skin physiology research, establishes a correspondence between different combinations of cosmetic and medical parameters and types of beauty devices 40. After obtaining the cosmetic and medical parameters, this unit conducts a comprehensive analysis of parameters such as skin moisture content, oil secretion, collagen content, skin elasticity, and blood circulation. Based on the rules in the rule base, it prioritizes 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 its efficient hydration function is preferred; for customers with sagging and inelastic skin, a 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 operating parameters based on the skin condition and the type of beauty device 40. For dehydrated skin, the moisture parameter generation unit 242 generates parameters for a higher frequency and longer operating time for the ultrasonic infusion beauty device 40 to enhance the hydration effect. It also generates parameters for low energy, multiple irradiations for the photorejuvenation beauty device 40 to promote skin water circulation. For excessive oil secretion, the oil parameter generation unit 243 generates parameters for high intensity, low frequency current for the microcurrent beauty device 40 to regulate sebaceous gland secretion. It also generates parameters for high energy, short single irradiation for the photorejuvenation beauty device 40 to suppress oil secretion. The other parameter generation units operate in the same manner, ensuring that the beauty device 40 operates optimally to provide personalized beauty treatments to customers.

[0026] Data Analysis Module 23: The data analysis module 23 implements in-depth mining and utilization of customer beauty data through the data integration unit 231, comparative analysis unit 232, and trend prediction unit 233. The data integration unit 231 integrates multiple sets of historical beauty data of the same customer from the 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; The comparative analysis unit 232 performs a longitudinal comparison of the integrated data, analyzing in detail the changing trends of various skin parameters over time. For example, it can compare the changes in skin moisture content before and after multiple treatments, observe the fluctuations in oil secretion in different seasons or treatment stages, understand the growth or decrease trend of collagen content over time, analyze the improvement in skin elasticity during treatment, and monitor changes in blood circulation. Through these comparative analyses, the effectiveness of previous cosmetic treatments can be intuitively evaluated. Based on the results of the comparative analysis, trend prediction unit 233 applies a time series analysis algorithm, such as the existing ARIMA model. The ARIMA model, short for the Autoregressive Integrated Moving Average model, is a commonly used prediction model in time series analysis. In your proposed beauty device technical solution, this model is primarily used to predict future trends in skin conditions. Using the ARIMA model, future trends in skin conditions are predicted. Based on the predicted results, a skin condition trend report is generated, providing a scientific basis for adjusting subsequent beauty treatment plans. For example, if a patient's skin collagen content is predicted to continue to decline, the treatment plan can be adjusted in advance, including treatments that stimulate collagen regeneration or adjusting the operating parameters of the beauty device 40.

[0027] Storage module 25: The storage module 25 is the data warehouse of the entire device, which is used to store the basic information of beauty medical personnel, such as name, age, gender, contact information, etc. This information helps to establish customer files and facilitates customer management and service tracking of beauty salons; at the same time, the storage module 25 also saves past beauty medical parameters, including skin moisture content, oil secretion, collagen content, skin elasticity and blood circulation status obtained from each test, providing rich historical data resources for the data analysis module 23; in addition, treatment effect records and scanning time and other information are also stored therein. Through comprehensive analysis of these data, the customer's beauty history and treatment effects can be fully understood, providing strong support for the formulation of personalized beauty plans.

[0028] Display Module 27: The design of display module 27 fully considers the beautician's operational convenience. After the working parameter generation module 24 determines the type of beauty device 40 required, display module 27 displays the type of beauty device 40 in real time in an intuitive and clear manner. This function effectively reduces the possibility of beauticians accidentally or misjudging the wrong beauty device 40, thereby improving the accuracy and efficiency of beauty treatments. For example, when display module 27 displays "Ultrasound Transduction Beauty Device 40," the beautician can quickly select the corresponding device from the equipment, avoiding the impact of selecting the wrong device and wasting time on the beauty treatment.

[0029] In the above-mentioned beauty instrument 40 functional module, the data reading module 41 serves as the data receiving entrance, which can quickly and accurately read the data in the inserted beauty parameter storage card 30, including the beauty instrument 40 type data and working parameter data, which are the instruction basis for the beauty instrument 40 to work.

[0030] The type matching module 42 matches the read type data of the beauty instrument 40 with its own preset type of beauty instrument 40. If the two are consistent, it means that the beauty instrument 40 is consistent with 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 match is unsuccessful, it indicates that the beauty instrument 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.

[0031] After receiving the activation signal from the type matching module 42, the operating parameter execution module 43 activates the corresponding functional components of the beauty device 40 based on the read operating parameter data. For example, for an ultrasonic beauty device 40, the operating parameter execution module 43 adjusts the frequency, intensity, and operating time of the ultrasound waves based on the operating parameter data to better deliver the beauty product deep into the skin. For a microcurrent beauty device 40, the operating parameter execution module 43 adjusts the intensity, frequency, and waveform of the current to stimulate skin muscle contraction and achieve the effect of improving skin firmness.

[0032] Upon receiving the trigger signal from the type matching module 42, the alarm module 44 immediately issues an audible and visual alarm. The audible prompt and flashing light quickly draw the beautician's attention, reminding them that the type data matching of the beauty device 40 is unsuccessful and that the beauty device 40 needs to be replaced in a timely manner, thereby ensuring the safety and effectiveness of the beauty treatment process.

[0033] like Figure 3-4 As shown, based on the above technical solution, a specific beauty process method is implemented, including the following steps: Step 1, equipment initialization: In the actual operation scenario of the beauty salon, the thermal infrared scanner 10, the data processing and analysis terminal 20, the beauty parameter storage card 30 and the beauty instrument 40 are reasonably arranged and connected, the data processing and analysis terminal 20 is initialized and set, and the beauty instrument 40 adaptation rule library is entered and improved in the beauty instrument type determination unit 241 of the working parameter generation module 24 to ensure that it contains the accurate correspondence between different beauty medical parameter combinations and the types of beauty instruments 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 instrument 40. Step 1, initial cosmetic treatment process: When a cosmetic medical practitioner first arrives at the clinic, the staff guides the patient to the thermal infrared scanner 10, instructs the patient to remain still and maintain a suitable distance between the patient's face and the scanner lens, and controls the temperature and humidity of the scanning environment within a preset range. The thermal infrared scanner 10 then activates and scans the patient's face, generating a thermal infrared image. The image is then quickly transmitted to the data processing and analysis terminal 20 via the data transmission interface 26; 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 discernible. Next, the feature extraction unit 222 uses an edge detection algorithm to extract skin edge contours, uses a threshold segmentation algorithm to segment different temperature regions, and calculates the grayscale value statistical features and texture features of different image regions to obtain skin temperature distribution features and vascular morphology features. Finally, the parameter calculation unit 223 uses the extracted features and combines them with a preset skin physiological model to calculate cosmetic and medical parameters such as skin moisture content, oil secretion, collagen content, skin elasticity, and blood circulation status. 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. The beauty instrument type determination unit 241 comprehensively analyzes the various parameters and prioritizes the required beauty instrument 40 type according to the rules of the beauty instrument 40 adaptation rule library. After the type of beauty instrument 40 is determined, each parameter generation unit generates appropriate working parameters based on the determined beauty instrument 40 type and skin condition. The generated data is sent to the beauty parameter storage card 30, and the beautician inserts the storage card into the beauty instrument 40; the data reading module 41 of the beauty instrument 40 reads the data in the storage card, and the type matching module 42 matches the read beauty instrument 40 type data with its own preset beauty instrument 40 type. If the match is successful, the working parameter execution module 43 drives the corresponding functional components of the beauty instrument 40 according to the read working parameter data to perform beauty treatment on the customer's face; if the match is unsuccessful, the alarm module 44 emits an audible and visual alarm to remind the beautician to replace the beauty instrument 40. Step 1, subsequent beauty treatment process: When the customer comes to the store for beauty treatment later, the data analysis module 23 of the data processing and analysis terminal 20 first integrates the multiple sets of historical beauty data of the customer in the storage module 25 and arranges them in chronological order; the comparative analysis unit 232 performs a longitudinal comparison on the integrated data and analyzes in detail the changing trends of various skin parameters in different periods; based on the results of the comparative analysis, the trend prediction unit 233 uses a preset time series analysis algorithm to predict the future development trend of the skin condition and generate a skin condition development trend report; if the report shows that there is no need to adjust the treatment plan, 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, and the customer inserts the card into the beauty instrument 40 for treatment; if the treatment plan needs to be adjusted, the thermal infrared scanner 10 is restarted to scan the customer's face, and the data processing and analysis process in the initial beauty treatment step is repeated, and the type of beauty instrument 40 and its working parameters are updated before treatment.

[0034] 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 embodied 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 illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
