A multi-spectral face-to-face diagnosis measurement method

Abstract

The invention discloses a multi-spectral face-to-face diagnosis measurement method, which belongs to the field of face-to-face diagnosis information collection in traditional Chinese medicine, specifically: firstly, aiming at the wavelength λ, using structured light with a spatial frequency fx to irradiate a calibration phantom of a known diffuse reflectance image , to obtain the response image of the phantom to the current spatial frequency; then, use the structured light to irradiate the face to be tested, and similarly obtain the response image and diffuse reflectance image; select another structure of spatial frequency fx' under the same wavelength λ Irradiate the calibration phantom and the face to be tested with light again to obtain a new diffuse reflectance image; use at least two diffuse reflectance images to calculate the optical absorption / scattering coefficient pair of the face to be tested at wavelength λ; finally, use The absorption and scattering coefficient pairs corresponding to different wavelengths are used to fit the hemoglobin concentration at each pixel position in the facial tissue to be tested for face-to-face diagnosis. The invention can quantitatively measure the absorption coefficient and hemoglobin concentration of facial tissue by using structured light, and provide richer information.

Description

Technical field [0001] The present invention belongs to the field of traditional Chinese medicine, which is specifically a multi-screen diagnosis measurement method. Background technique [0002] During the existing TCM face consultation, the light-illuminated surface of different wavelengths is usually employed, and the acquisition of facial information is performed by collecting the reflected optical wavelength, the mating pattern identification technology is used, thereby performing the next diagnosis. "Traditional Chinese Medicine Face Treatment System" is 200710045884.2; however, this system cannot obtain quantified hemoglobin information, and hemoglobin information is closely related to tissue blood oxygen, metabolism, etc., a single position of hemoglobin information obtained, The hemoglobin distribution of the entire face can be obtained by facing the facial imaging, which is much greater than the blood-protein information measured by blood tampon.

Problems solved by technology

For example, the "Traditional TCM facial complexion inspection system" with the publication number 200710045884.2; however, this system cannot obtain quantitative hemoglobin information, which is closely related to tissue blood oxygen and metabolism; compared with the single-position hemoglobin information obtained by blood drawing, The hemoglobin distribution of the entire face can be obtained through facial imaging, and the amount of information is much greater than the hemoglobin information measured by blood drawing
