More Information
Summary:The skin detection method comprises the steps that first polarized light and second polarized light are alternately emitted through a light source to irradiate skin, corresponding images are collected, and the polarization directions of the first polarized light and the second polarized light are different; pixel information of the image is extracted; carrying out downsampling processing on the pixel information, and obtaining a difference matrix of the pixel information; the difference value matrix is subjected to visual conversion, and a skin thermodynamic diagram is obtained; compared with an existing PPGI living body skin detection method, the method has the advantages that the reflected light on the surface of the skin is filtered out through polarization, deeper and more accurate information is provided for analysis, and therefore the accuracy and real-time performance of living body skin detection and physiological monitoring are improved. 本发明公开了基于多光谱偏振光的皮肤检测方法及装置，包括：通过光源交替发射第一偏振光和第二偏振光照射皮肤，采集对应图像，其中所述
