Abstract: A method for measuring the actual distance of a human body based on a cornea image and a method for customizing a spectacle frame. The measurement method comprises the following steps: step 1, acquiring a front-view photograph with at least one dark part of eyes, or capturing a frame of a front-view image with at least one dark part of eyes from a video; step 2, detecting and positioning the first dark part; step 3, determining a max horizontal radius Lp of the first dark part; step 4, determining a proportionality factor ? of an actual linear geometric size to a linear size in the photograph or the frame; and step 5, measuring an actual image distance between any two points, and multiplying the actual image distance by the proportionality factor ? to obtain an actual distance between the two corresponding points on human body.
