Embodiment 1
[0102] Step 1. Construct a three-dimensional skin condition comprehensive evaluation system;
[0103] Select eight test indicators of water content, water loss, oil, melanin MI, skin color IAT, gloss, elasticity R2, and roughness Rz to form the index position set, and form the test index element d in turn 1 , d 2 … d 8 , then the indicator position set is x 1 ,x 2 …x 8 , constituting the x input of the three-dimensional skin state comprehensive evaluation system. Select the forehead, left eye corner, left cheek, and chin to form the test site set, and form the test site y in turn 1 ,y 2 ,y 3 ,y 4 , constituting the y input of the three-dimensional skin state comprehensive evaluation system.

The invention discloses a skin state comprehensive evaluation method based on a projection integral function based on three-dimensional coordinates, and belongs to the engineering technical field of cross-integration of skin science and system science. The evaluation method first establishes the three-dimensional coordinates of the index position set, the test part set, and the fuzzy evaluation set. According to the evaluation criteria given by the experts in the field, a projection integral function is proposed to perform interpolation and integration calculations on the test data of the test parts, and project them on the index dimension to perform The quadratic interpolation integral uses the fuzzy membership degree to express the progressive uncertainty of the evaluation level of the skin state, and finally calculates and determines the comprehensive evaluation level of the skin state through the fuzzy matrix. The judging result of the invention can comprehensively and objectively reflect the skin state, improves the comprehensiveness of evaluation, and improves the objective accuracy of the result; it provides reference significance for testers to use cosmetics and other products.
Description
technical field [0001] The invention relates to a multi-indicator and multi-part skin condition comprehensive evaluation method, which belongs to the engineering technical field of cross-integration of skin science and system science, specifically, it is the basis for in-depth study of skin index test data characteristics and evaluation criteria in the field First, the test data of various parts of the skin and various indicators are processed and calculated by constructing a projection integral function, and a comprehensive and effective evaluation method that can reflect the state of the skin is explored. Background technique [0002] With the gradual improvement of human living standards, after solving the basic problems of food, clothing, housing and transportation, people are paying more and more attention to their health and beauty. As the outermost protective film covering the body, the skin plays the role of resisting bacteria and regulating body temperature, and it ...
