1. A method for locating head side acupuncture points, comprising:
training an acupuncture point identification model based on a head side acupuncture point sample set to obtain a target acupuncture point identification model, wherein the head side acupuncture point sample set comprises a plurality of acupuncture point sample points and a plurality of support sample points in a curve of gallbladder meridian of foot-shaoyang;
inputting a head side image to be identified to the target acupuncture point identification model to obtain a plurality of acupuncture points and a plurality of support points;
fitting the plurality of acupuncture points and the plurality of support points to obtain a fitted curve; and
determining whether the acupuncture points require correction based on the fitted curve, and if yes, correcting the acupuncture points based on the fitted curve to obtain target acupuncture points;
before the training an acupuncture point identification model based on a head side acupuncture point sample set, the method further comprises:
acquiring a plurality of head side sample images, and determining the curve of gallbladder meridian of foot-shaoyang in each of the head side sample images;
marking acupuncture points based on the curve of gallbladder meridian of foot-shaoyang to obtain the plurality of acupuncture point sample points;
segmenting the curve of gallbladder meridian of foot-shaoyang based on inflection points of the curve of gallbladder meridian of foot-shaoyang to obtain a plurality of sub-curves of gallbladder meridian of foot-shaoyang; and
determining, based on a number of the acupuncture point sample points in each of the sub-curves of gallbladder meridian of foot-shaoyang and a curve feature, at least one support sample point inserted to the sub-curve of gallbladder meridian of foot-shaoyang;
wherein the curve feature comprises a curvature variation rate and a curve length; and the determining, based on a number of the acupuncture point sample points in each of the sub-curves of gallbladder meridian of foot-shaoyang and a curve feature, at least one support sample point inserted to the sub-curve of gallbladder meridian of foot-shaoyang comprises:
when the curvature variation rate of the sub-curve of gallbladder meridian of foot-shaoyang is less than or equal to a first threshold, a total number of support sample points and acupuncture point sample points in the sub-curve of gallbladder meridian of foot-shaoyang being a first threshold number, and determining a target number of support sample points inserted to the sub-curve of gallbladder meridian of foot-shaoyang based on the first threshold number and the number of the acupuncture point sample points;
when the curvature variation rate of the sub-curve of gallbladder meridian of foot-shaoyang is greater than the first threshold and the curve length of the sub-curve of gallbladder meridian of foot-shaoyang is less than or equal to a length threshold, the total number of support sample points and acupuncture point sample points in the sub-curve of gallbladder meridian of foot-shaoyang being a second threshold number, and determining a target number of support sample points inserted to the sub-curve of gallbladder meridian of foot-shaoyang based on the second threshold number and the number of the acupuncture point sample points;
when the curvature variation rate of the sub-curve of gallbladder meridian of foot-shaoyang is greater than the first threshold and the curve length of the sub-curve of gallbladder meridian of foot-shaoyang is greater than the length threshold, the total number of support sample points and acupuncture point sample points in the sub-curve of gallbladder meridian of foot-shaoyang being a third threshold number, and determining a target number of support sample points inserted to the sub-curve of gallbladder meridian of foot-shaoyang based on the third threshold number and the number of the acupuncture point sample points; and
inserting the target number of support sample points to the sub-curve of gallbladder meridian of foot-shaoyang;
wherein the first threshold number is less than the second threshold number, and the second threshold number is less than the third threshold number.
