Visual skin wrinkle assessment method and system

Abstract

The invention discloses a visual skin wrinkle assessment method and system and belongs to the field of skin detection technology. The method comprises the steps that an image collection device is adopted to shoot face images associated to the same face, and a dermatoscope sends the face images into a cloud server; the cloud server obtains unit normal vectors of all pixel points through photometricstereo processing and obtains surface depth information of all the pixel points through processing to form a face stereo image of the face; and then a pre-trained formed skin wrinkle assessment modelis adopted to make a judgment on the face stereo image so as to obtain skin wrinkle assessment results corresponding to different face positions in the face stereo image, the skin wrinkle assessmentresults are associated to corresponding face positions in a display template to form graphical wrinkle assessment results, and the graphical wrinkle assessment results are output. The visual skin wrinkle assessment method and system have the advantages that a user can view the wrinkle assessment results of different face positions in the face stereo image more directly in a user terminal and thenadopt pertinent skin care.

Description

technical field [0001] The invention relates to the technical field of skin detection, in particular to a visual skin wrinkle evaluation method and system. Background technique [0002] With the improvement of people's quality of life, more and more people, especially women, begin to pay attention to their own skin conditions, and more and more skin care products for skin conditions also occupy a very important position in the market.

Problems solved by technology

[0004] In the current market, although there are some skin detection devices, such as skin detectors, etc., the price of these skin detection devices is relatively expensive, and the operation is very complicated, which is not suitable for users to use at home.

At the same time, the detection principle of these skin detection equipment is usually only through the sensory data collected by some sensors for plane data processing, and will not involve the problem of three-dimensional facial reconstruction, so it will be better for oily skin, skin dehydration and other skin conditions. detection effect, but the detection effect for the skin condition of facial skin wrinkles is not good, which cannot meet the needs of users
