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 three-dimensional coordinates based skin state comprehensive evaluation method using a projection integral function, and belongs to the technical field of cross fusion of skin science and system science. The evaluation method comprises: firstly, establishing three-dimensional coordinates of an index position set, a test part set and a fuzzy evaluation set; secondly, for evaluation standards given by field experts, proposing the projection integral function to perform interpolation integral operation on test data of a test part, performing secondary interpolation integral on a projection index dimension, and expressing progressive uncertainty of a skin state evaluation grade by adopting fuzzy membership degree; and finally, calculating and determining the skin state comprehensive evaluation grade through a fuzzy matrix. According to the method, a determining result can reflect a skin state comprehensively and objectively, so that the comprehensiveness of evaluation is improved and the objective accuracy of the result is improved; and reference significance is provided for the use of testers to products such as cosmetics and the like.
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 ...
