[0002] Traditional cosmetic safety assessments mainly rely on animal experiments and clinical trial data, with limited sample sizes, which make it difficult to fully reflect actual consumer usage. The antioxidant response of cosmetics is a dynamic process that is affected by the characteristics of the cosmetics themselves, as well as by the user's skin condition, environmental factors, and other factors. Traditional static statistical models are difficult to describe this complex dynamic relationship. Cosmetic antioxidants should differ significantly among different users, and some people are more sensitive to specific ingredients or doses of multiple cosmetics used in combination.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] The traditional method of testing the antioxidant capacity of cosmetics is mainly to add various chemicals, solubilizers and extraction solutions to the samples to be tested. However, these methods change or destroy the original chemical formula of the cosmetics. Therefore, the traditional detection methods cannot be used to test cosmetic samples. In addition, the traditional methods only use detection agents that are sensitive to one type of active oxygen or active nitrogen, and cannot comprehensively evaluate the antioxidant capacity of cosmetics.

[0018] In view of this, the purpose of the present invention is to provide a human quantitative evaluation method and application for the antioxidant efficacy of various cosmetics, so as to achieve accurate and rapid detection of skin quality.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1 Abnormal skin information: a type of skin surface feature that is inconsistent with the statistical properties of the skin at a long spatial scale. In particular, it refers to features that are formed due to significant changes in external skin contact within a smaller spatial range (such as rosacea, dermatitis, rashes, blackheads, etc.).

[0021] Multi-source input superposition model and its function: A method of superimposing and correcting the test records of multiple cosmetics to achieve skin quality (abnormal information) detection.

[0022] This embodiment takes into account the limitations of spatial detection and allergy sensor detection, and performs skin quality detection under the superposition of multi-source input signals such as ultraviolet sensors, air quality sensors, and photosensors. The superposition between the two is achieved based on the cosmetic position coordinates, and the position deviation value range is fully considered during the superposition process. Specifically, this embodiment includes constructing a skin detection correction model using the distribution of cosmetic position deviation values, and using the skin abnormality information detected by the allergy sensor to correct the skin abnormality information detected by the perception sensor, and obtaining a perception record by superimposing the two. The skin detection method consists of two parts: multi-source input superposition abnormal information detection and superposition weight calculation. Therefore, the present invention provides a human quantitative evaluation system for the antioxidant efficacy of cosmetics, including: a sample position unit, an information acquisition unit, a sample position deviation value calculation unit, a skin abnormality information identification unit, a weighted formula generation unit, and a skin abnormality information superposition unit.

[0023] The information collection unit includes an allergy sensor information collection unit and a perception sensor data collection unit.

[0024] The allergy sensor information acquisition unit is used to collect cosmetic status data (such as cream, water, and lotion) through the allergy sensor, and to detect the vertical sliding characteristics of cosmetics along the skin and the changes in the cosmetic status in real time; the perception sensor data acquisition unit is used to collect the original skin bare face information during the cosmetics application process through the infrared sensor, and to collect the skin makeup image data during the cosmetics application process through the camera, and send the records obtained from the above two to the skin abnormality information recognition unit.

[0025] The skin abnormality information recognition unit includes a response-based skin abnormality information recognition model and a spatial skin abnormality information recognition model.

[0026] The response-based skin abnormality information recognition model is used to perform feature detection on cosmetic ingredient data to obtain skin abnormality information along the cosmetic application range with application site data. The response-based skin abnormality information recognition model includes a cluster analysis model, a perturbation observer detection model, and a threshold-based detection method.

[0027] The spatial skin abnormality information recognition model includes an information analysis unit and a data superposition unit; wherein the information analysis unit includes an infrared sensor information analysis unit and a camera information analysis unit. The camera information analysis unit performs grayscale, noise reduction, binarization and other denoising and feature space-based clustering analysis and segmentation processing on the skin makeup image data collected by the camera to obtain a depth image with skin abnormality information. The infrared sensor information analysis unit performs noise reduction, image pixel segmentation, image pixel clustering and other processing on the original skin makeup information collected by the infrared sensor to obtain free radical data antioxidant capacity information containing skin abnormality information. The data superposition unit determines whether the infrared sensor information analysis unit and the camera information analysis unit both output information containing skin abnormality information, so as to select different superposition models, and then output the final spatial skin abnormality information with application site data.

[0028] The visual skin abnormality information recognition model, the infrared sensor skin abnormality information recognition model, and the superposition model described in this embodiment are not limited to the above methods.

[0029] The sample position deviation value calculation unit takes the tracking system deviation value and the fluorescence intensity analysis system deviation value as input, obtains the sample tracking deviation value (expressed by standard deviation σ) by superposition calculation of the deviation values, and inputs the sample tracking deviation value into the weighted formula generation unit.

[0030] The weighted formula generation unit is used to construct a weighted formula using the sample tracking information deviation value (σ) as input (the weighted formula described below is only an example).

[0031] The skin abnormality information superposition unit is used to judge whether the cosmetics cover the position area corresponding to the spatial skin abnormality information based on the evaluated cosmetic position (here is the application order of the cosmetics mentioned below) and the spatial skin abnormality information with the application site data. If it is judged that it does not cover, the spatial skin abnormality information is output; if it is judged that it covers, the input multi-source detected skin abnormality information (i.e., the spatial skin abnormality information with the application site data and the skin abnormality information along the cosmetic application range with the application site data) is weighted using a weighting formula to obtain the superimposed skin abnormality information with the application site data.

[0032] The above is an introduction to the various parts of the skin quality detection system. The following is a detailed introduction to the corresponding methods of the described skin quality detection system: First, two global coordinate systems are established, namely the human body coordinate system (X, Y, Z) and the sample coordinate system (x, y, z). The right-handed coordinate system, i.e., the sample coordinate system, is established with the point where the sample touches the human body as the origin, the cosmetic application range as the positive range of the x-axis, and the vertical upward as the positive range of the z-axis.

[0033] The ordinates of the human body coordinate system (X, Y, Z) and the sample coordinate system (x, y, z) are the same, that is, Z = z. The coordinate transformation of the abnormal information in the sample coordinate system and the human body coordinate system is as follows: Assume that the coordinates of the abnormal information in the sample coordinate system are (x1, y1, z1) and the coordinates in the human body coordinate system are (X1, Y1, Z1). The transformation matrix between the sample coordinate system and the human body coordinate system is: ,but , Z1=z1.

[0034] in, , .

[0035] R is the rotation matrix, and T is the coordinate of the origin of the sample coordinate system in the human body coordinate system.

[0036] Step 1: When cosmetics are applied normally, the allergy sensor starts to collect cosmetic attribute data, which includes but is not limited to application status data, ingredient data, etc.; the perception sensor collects skin data of body parts, among which the infrared sensor collects the original skin information during the cosmetics application process, and the camera collects the skin makeup image data during the cosmetics application process as the input of the skin abnormality information recognition unit.

[0037] Step 2: After the skin abnormality information recognition unit collects the information input by the information collection unit, it processes the cosmetics attribute data based on the corresponding skin abnormality information recognition model to obtain abnormal information. Specifically, firstly, an abnormal information threshold is set, and then whether it is abnormal information is determined based on whether the z-axis acceleration of the cosmetics input by the allergy sensor is greater than the abnormal information threshold. The length l1 and depth z of the abnormal information along the central axis of the sample are calculated to obtain an image of the skin abnormality information along the central axis of the sample; wherein, in the image of the skin abnormality information along the central axis of the sample, in the sample coordinate system, the x-axis is the cosmetics application range, the z-axis is the vertical range, and the xz coordinate system is the spatial coordinate, that is, what is obtained is the depth of the abnormal information along the cosmetics application range.

[0038] Among them, the depth z of each point along the x range of skin abnormality information can be regarded as the formula f(x,y) of the horizontal and vertical coordinates (x,y). Here, the coordinates are fixed to the center of the skin where the cosmetic sample is connected, so its vertical coordinate is zero, that is, y=0. The horizontal coordinate of point M is x1, and the depth is z1, then z1=f(x1,0).

[0039] The spatial skin abnormality information recognition model includes an information parsing unit and a data superposition unit.

[0040] After receiving the skin data of the body part sent in step 1, the information analysis unit processes the original skin information, including: first performing image pixel denoising, image pixel segmentation and other denoising, using a clustering model to perform clustering analysis on the denoised original skin information, and obtaining free radical data antioxidant capacity information with skin abnormality information as input to the data superposition unit. The denoised skin image is segmented using a segmentation model to obtain a depth image containing skin abnormality information as input to the data superposition unit.

[0041] The data superposition unit determines whether the infrared sensor information analysis unit and the camera information analysis unit in step 2 have both output information containing skin abnormality information, which is divided into three situations: 1. When only the infrared sensor information analysis unit outputs information containing skin abnormality information, the bounding box is fitted on the antioxidant capacity information of the free radical data containing skin abnormality information to obtain the abnormal information and use it as the spatial detection of skin abnormality information.

[0042] 2. Only the camera information analysis unit outputs the information containing skin abnormality information. The convolutional neural network model is used to perform feature detection on the depth image containing skin abnormality information to obtain the abnormal information and use it as the spatial detection of skin abnormality information.

[0043] 3. When both the infrared sensor information analysis unit and the camera information analysis unit output information containing skin abnormality information, the data are first synchronized in time to obtain the infrared sensor antioxidant capacity information and camera data after feature detection at the same time; then spatial synchronization is performed to convert the antioxidant capacity information into the image coordinate system to achieve spatial data matching between the infrared sensor and the camera; then the sensor data are superimposed to obtain superimposed data; finally, the superimposed data is fitted with a bounding box to obtain abnormal information and use it as spatial detection of skin abnormality information.

[0044] The depth z of each point in the spatially detected skin abnormality information is a formula corresponding to the horizontal and vertical coordinates, that is, z=g(x,y).

[0045] Step 3: While the allergy sensor is collecting information, the sample position unit is also collecting information and calculating the sample application site data in real time. The sample application site data can be calculated through the center position, the mean value of the cosmetic color, the current sensed by the cosmetic skin, etc. Specifically, the data of the cosmetic center application site is first collected in real time through the GPS tracking system, and the cosmetic application thickness θ, the center color mean β, etc. are collected in real time through the fluorescence intensity analysis system. Then, the cosmetic coverage area ψ is calculated by formula (1), and then the sample position is calculated based on the cosmetic coverage area ψ and the cosmetic center application site data.

[0046] Evaluate the order of applying cosmetics based on the sample application site data.

[0047] Step 4: The deviation of the fluorescence intensity analysis system conforms to the normal distribution with a mean of 0 and a standard deviation of σ1, and the deviation of the tracking system conforms to the normal distribution with a mean of 0 and a standard deviation of σ2. In the process of calculating the sample position, it is assumed that the deviation of the fluorescence intensity analysis system and the tracking system are independent of each other. The deviation of the sample position is calculated by superimposing the deviation of the fluorescence intensity analysis system and the deviation of the tracking system. Therefore, the deviation of the sample position also conforms to the normal distribution with a mean of 0 and a standard deviation of σ.

[0048] Step 5: Construct a superposition model weighting formula based on the sample position deviation value output from step 4 (the superposition model weighting formula shown below is for example only).

[0049] Step 6: Determine whether the cosmetics cover the position area corresponding to the spatial skin abnormality information according to the position corresponding to the spatial skin abnormality information output in step 2 and the cosmetics application order output in step 3.

[0050] If the cosmetics do not cover the location area corresponding to the spatial skin abnormality information, the spatial detected skin abnormality information is output. If the cosmetics cover the location area corresponding to the spatial skin abnormality information, the different skin abnormality information output in step 3 is superimposed and weighted by using the superposition model weighting formula output in step 5 to obtain the superimposed skin abnormality information.

[0051] The superposition model weighted formula is: The sample skin area deviation σ and sample temperature and humidity B output in step 4 are used as input to construct the weight value formula, and the weight value ξ of the superimposed weighted formula is calculated according to the weight value formula y and 1-ξ y (where ξ y is the weight value of skin abnormality information along the cosmetic application range, 1-ξ y is the weight value of spatial skin abnormality information).

[0052] ; According to the calculated weight value β of the superposition weighted formula, the abnormal information obtained in step 2 is extended along the y-axis range. In the section where the abnormal information covers the vertical x-axis range of point M, the coordinates of point M are (x1,0,z1) and the coordinates of point N are (x1,y2,z2). .

[0053] The depth of each point of skin abnormality information is the formula of the horizontal and vertical coordinates corresponding to the point, that is, z=f(x,y).

[0054] According to the weight value, the weighted formula of the superposition model is constructed as shown in formula (1): ; The coordinates described in the above formula are all in the sample coordinate system. g(x,y) is the depth of each coordinate point of the visually detected skin abnormality information, f(x,y) is the depth of each coordinate point of the response detected skin abnormality information, and (x,y,z) is the coordinate of the superimposed skin abnormality information.

[0064] When the skin data of a body part includes original skin information without makeup and skin image data with makeup, the steps described in this embodiment: performing feature detection on the skin data of the body part to obtain spatial skin abnormality information with makeup part data specifically include: The original bare-face information and the skin with makeup image data are denoised respectively; feature detection is performed on the denoised original bare-face information based on the spatial skin abnormality information detection model to obtain a first record; feature detection is performed on the denoised skin with makeup image data based on the spatial skin abnormality information detection model to obtain a second record.
