Light can be emitted to the user's face from both sides to generate cross-polarized light on the skin to be tested to obtain polarized light photos. In other embodiments, the polarized light source 143 can also be a strip shape arranged along the horizontal direction, or two or more other numbers of polarized light sources that are separately arranged, and after emitting light to the face, it is placed on the skin to be tested. Produces cross-polarized light. Based on the polarized light source 143, the polarized light photos taken are clearer, and the superficial layer of the skin can be observed, and the reflection on the skin surface can be filtered out, so that the spots on the skin surface are clearly visible, and the area and distribution of sensitive parts of the face can be displayed. Usually, polarized light can be used The photo detects one or more of the foregoing.

Different photos are taken under the three light sources 14, photos of different attributes can be obtained, and the shooting sequence is not limited. The processing unit is used to analyze the photos of sunlight, UV light, and polarized light to obtain the skin to be tested. index of.

Therefore, the skin measurement system facilitates comprehensive analysis of the user's skin characteristics to be tested, and obtains accurate skin characteristics, so as to provide accurate skin care guidelines for the user. In other embodiments, the UV light source and the white glass slide can also be omitted, and only the sunlight photos and polarized light photos obtained by shooting are analyzed to obtain the corresponding indicators of the skin to be tested.

Further, the skin measuring system also includes a prompting unit, which is used to issue guidelines or contraindications for the use of cosmetics according to the indicators obtained by the processing unit. Since the characteristics of the skin to be tested have been fully measured, instructions on which cosmetics to use and which cosmetics cannot be used can be made based on the characteristics, as well as the ingredients and functions of commonly used cosmetics.

Preferably, the prompting information issued by the prompting unit such as guidelines for use and contraindications for use can be displayed on the display screen 13, allowing the user to directly observe, or the prompting unit can send relevant data indicators of skin characteristics, guidelines for use, Use contraindications, etc. are sent to the user's mobile phone and other terminals to receive them, and are saved and collected by the user after being acquired, so as to facilitate the subsequent targeted selection of cosmetics.

The processing unit can be integrated in the smart cosmetic mirror to process the obtained indicators of the skin to be tested. The processing unit can also be set on the server. The smart makeup mirror communicates with the server through the communication module to realize data transmission. The image collected by the skin measurement system can be sent to the server for analysis through the communication module, and the obtained skin indicators are then sent to the smart makeup mirror. or displayed on the user's smart terminal.

By presetting the photo database of different skin types under the above three kinds of light, and the skin texture algorithm established based on the analysis of the photo database, according to the analysis of sunlight photos, UV light photos, and polarized light photos, the skin to be tested can be obtained. index.

When taking the photos above for skin testing, you can choose the quick test, which only tests one direction of the front of the face, or you can choose the full test, and choose several directions for each light to test after shooting, such as the front, left, and right of the face. direction. No matter which direction, the testing process is the same, and the photos are taken under three kinds of light.

Preferably, during the shooting process, the image acquisition unit can judge the distance position of the user relative to the camera 15 according to the obtained photo of the user in front of the lens, and intelligently remind the user to approach or stay away from the camera 15 so that the face is at an appropriate distance, and a more complete picture can be captured. The collected images can be previewed on the display screen. At the same time, according to the captured user’s actions in front of the lens, the user can be reminded to look directly at the camera lens 15 or rotate to a specified angle, and to remind the user to close their eyes and capture the position of the eyelids. images for testing and analysis.
