[0019] The following is a further detailed description of a skin allergy determination system and a skin allergy determination method proposed by the present invention in conjunction with the accompanying drawings and specific embodiments.

[0020] See also Figure 1 , 2 ,in Figure 1 This is a schematic diagram of a contact allergen test paper in a specific embodiment of the present invention. Figure 2 The figure is a schematic diagram of the connection relationship between the image analysis module and the image acquisition module in a specific implementation manner of the present invention.

[0021] In this specific embodiment, a skin allergy determination system is provided, including: a contact allergen test paper 101, having a test surface and an exposed surface, wherein the test surface is used to be attached to the user's skin and is coated with at least two contact chemical allergens, and the exposed surface is provided with identification points 102, corresponding to the positions of the test surface coated with the contact chemical allergens; an image acquisition module 201, used to acquire an image of the user's skin attached with the contact allergen test paper 101, and upload it to a server; an image analysis module 202, connected to the image acquisition module 201, used to analyze the user's skin allergy status regarding contact chemical allergens according to the acquired image.

[0022] In a specific embodiment, the number of the identification points 102 corresponds to the type of contact chemical allergens coated on the test surface. In a specific embodiment, the number of the identification points 102 is 20, and each identification point 102 corresponds to a contact chemical allergen, so a contact allergen test paper 101 can simultaneously perform allergy tests for up to 20 contact chemical allergens. In a specific embodiment, the distance between two adjacent identification points 102 is the same.

[0023] In a specific implementation, the marking points 102 are arranged in a matrix, with equal distances between rows and equal distances between columns.

[0024] In a specific embodiment, the size of the identification point 102 should be small enough so that when the contact allergen test paper 101 is attached, the wound formed on the skin caused by the contact chemical allergen can be obtained without being covered by the identification point 102 of a certain color.

[0025] In a specific embodiment, the contact allergen test paper 101 is transparent, and in addition to the contact chemical allergens, the test surface is also coated with adhesive for the user to attach to the skin for a long time. In a more preferred specific embodiment, the identification point 102 is also transparent, but in a specific embodiment, the identification point 102 has a color difference with the non-identification point of the exposed surface. When the non-identification point of the exposed surface is colorless and transparent, the identification point 102 may be red transparent or green transparent, etc., and has a certain color difference with the non-identification point, and the color difference is large enough so that the image collected when the light conditions are not good can also meet the requirements for image analysis.

[0026] The exposed surface is also provided with a mark 103 for indicating the posting direction of the contact allergen test paper 101. In a specific embodiment, the mark 103 includes Arabic numerals or English letters set at the identification point 102.

[0027] In a specific embodiment, the image acquisition module 201 includes a camera for acquiring images of the user's skin with the contact allergen test paper 101 applied thereto, including images of the skin before application, images of the skin just applied thereto, and images of the skin after application for a certain period of time. All of these can be completed by the user with the help of others. Since images at three different times are collected, the image analysis module 202 obtains more accurate results when determining the user's skin condition parameters, because the image analysis module 202 can combine the images of the skin at three different times to remove some interference items, such as inconspicuous wounds caused by dark skin color.

[0028] It should be noted that when collecting images, the lighting conditions should be kept consistent or similar as much as possible.

[0029] In a specific implementation, the acquired image is transmitted to the image analysis module 202 , and the image analysis module 202 analyzes the image.

[0030] The image analysis module 202 includes: a marker point recognition unit 203, which is used to recognize the marker points and determine the type of contact chemical allergen corresponding to each marker point 102; and a skin condition analysis unit 204, which is used to analyze the user's skin condition at each marker point and obtain user skin condition parameters.

[0031] In a specific implementation, the image acquisition module is set on some mobile terminals, such as tablet computers, mobile phones, etc. These devices are generally provided with cameras, which can be used as image acquisition modules to obtain user skin images. The image analysis module 202 is set in an external server, and a large number of databases are stored in the external server, which can be used by the image analysis module 202 to perform image analysis and obtain user skin condition parameters.

[0032] The image analysis module 202 is arranged in an external server, rather than being arranged together with the image acquisition module on the mobile terminal, which greatly reduces the computing pressure of the mobile terminal and speeds up the image analysis processing.

[0033] In fact, the image analysis module 202 and the image acquisition module can also be set together on the same mobile terminal, and the database related to image analysis is set in an external server. In this case, to perform data analysis on the mobile terminal, it is necessary to call the relevant data in the external server in real time, obtain and download all the data related to image analysis in the entire external server, which takes up a lot of memory.

[0034] In a specific embodiment, the identification point recognition unit 203 needs to use the identification number 103 to determine the contact chemical allergens corresponding to the multiple identification points 102. This is because the appearance of each identification point 102 is consistent, and the user is likely to be irregular in the process of posting the contact allergen test paper 101. Therefore, when the image analysis module 202 analyzes the image, a reference point is required to calibrate the specific position and direction of each identification point 102 in the image. In a specific embodiment, the number of the identification numbers 103 is two. In fact, the number of the identification numbers 103 can be set as needed.

[0035] In a specific implementation, the user skin condition parameter includes at least one of a wound redness and swelling degree parameter, a wound ulceration degree parameter, and a wound size parameter.

[0036] In a specific embodiment, the database includes various databases related to parameters of wounds caused by various allergies.

[0037] The determination of wound redness and swelling parameters can be achieved with the help of a wound redness and swelling database. The database stores relevant data for wound redness and swelling analysis. By searching and comparing the wound redness and swelling in the collected image with the wound redness and swelling database, the wound in the collected image is classified into redness and swelling levels.

[0038] The determination of wound ulceration degree parameters can also be achieved by using the same method with the help of a wound ulceration degree database, which stores relevant data for wound ulceration degree analysis.

[0039] In a specific embodiment, during the image recognition and analysis process, the collected images are first scaled to a preset standard size, and after removing some interference items, such as skin color interference items, using the images collected at multiple time points, the wound condition of the skin under the marking point 102 is analyzed. For example, the wound size is analyzed. When the size of the wound exceeds 1.5m from the marking point, it is determined to be a large wound size; when the size of the wound exceeds 1 to 1.5cm from the marking point, it is determined to be a medium wound size; when the size of the wound exceeds 0.1 to 1cm from the marking point, it is determined to be a small wound size.

[0040] It should be noted that all the acquired images are scaled to a preset standard size, and only the images with the marked points need to be scaled. When acquiring images at different time points, in addition to keeping the light source as consistent as possible, it is also necessary to keep the distance between the image acquisition module and the skin covered with the contact allergen test paper as consistent as possible, so that the scaling of the image before the contact allergen test paper is applied can be omitted.

[0041] In a specific implementation, the image acquisition module is connected to the image analysis module 202 via a network.

[0042] In actual use, a color recognition database, a shape recognition database, and a combination recognition database can also be constructed in an external server. These databases can be used in combination with the image analysis module to perform color analysis, shape analysis, and combination analysis. In this specific implementation, the color recognition database, shape recognition database, and combination recognition database are all databases that can be used for deep learning and can be used for real-time learning. During each analysis, the image analysis module 202 will also store the analyzed image and the results of the analysis in the external server, and the external server will select the corresponding data to update and optimize each database. The results obtained after using the image analysis module 202 for image analysis will become more and more accurate.

[0043] Uploading the analysis results of the image analysis module 202 to the external server also facilitates the sharing of images and analysis results. In this way, if necessary, the entire external server can be opened to qualified hospitals without disclosing the real identity of the user, so that the hospital can conduct statistics on the skin allergies of the people.

[0044] The skin allergy determination system of the present invention has an image recognition function, and can directly capture images of the user's skin covered with the contact allergen test paper 101, and perform image recognition analysis on the captured images to confirm the relevant parameters of the wounds generated on the skin surface during allergies, thereby confirming the final cause and degree of allergies.

[0045] See also Figure 3 , is a flow chart of a method for determining skin allergy in a specific embodiment of the present invention.

[0046] In this specific embodiment, a method for determining skin allergies is provided, comprising the following steps: S31, providing a contact allergen test paper 101, wherein the contact allergen test paper 101 has a test surface and an exposed surface, wherein the test surface is used to be attached to the user's skin and is coated with at least two contact chemical allergens, and the exposed surface is provided with identification points 102 corresponding to the positions of the test surface coated with contact chemical allergens; S32, attaching the contact allergen test paper 101 to the user's skin; S33, collecting an image of the user's skin attached with the contact allergen test paper 101; S34, analyzing the user's skin allergy condition based on the image.

[0047] In a specific embodiment, an image of the skin is collected just after the contact allergen test paper 101 is applied, and an image of the skin is collected after a certain period of time after the contact allergen test paper 101 is applied. Preferably, an image of the skin before the contact allergen test paper 101 is applied is also collected. All of these can be completed by the user with the help of others.

[0048] Since images are collected at three different times, the results obtained when analyzing the user's skin allergy condition are more accurate. This is because the images at three different times can remove some interference factors, such as the wound caused by dark skin color is not obvious.

[0049] In fact, more images may be acquired as needed for image analysis.

[0050] In a specific embodiment, after the contact allergen test paper 101 is applied to the user's skin for a first preset time, an image of the user's skin with the contact allergen test paper 101 applied is collected. In a specific embodiment, the first preset time is 48 hours. The first preset time is long enough to allow the skin to fully react with the contact chemical allergen.

[0051] In a specific embodiment, the exposed surface is also provided with a marking number 103 for indicating the posting direction of the contact allergen test paper 101. When analyzing the user's skin allergy condition based on the image, the following steps are included: determining the type of contact chemical allergen corresponding to each identification point 102 through the marking number 103.

[0052] In a specific embodiment, a variety of image recognition algorithms are used, including color recognition algorithms, shape recognition algorithms, machine learning algorithms, deep learning algorithms, etc., to analyze the condition parameters of the user's skin covered with the contact allergen test paper 101, including at least one of the wound redness and swelling degree parameters, wound ulceration degree parameters, and wound size parameters.

[0053] The method for determining skin allergies of the present invention has an image recognition function, and can directly capture images of the user's skin covered with contact allergen test paper 101, and perform image recognition analysis on the captured images to confirm the relevant parameters of the wounds generated on the skin surface during allergies, thereby confirming the final cause and degree of allergies.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
