Method for measuring actual distance of human body and customizing spectacle frame

Abstract

The invention discloses a method for measuring actual distance of a human body based on a cornea image. The method comprises the following steps: (1) acquiring a front photo image with an eye black part or capturing a frame of front picture with the eye black part from a video; (2) detecting and positioning the eye black part; (3) determining the transverse maximum length of the eye black part; (4) determining the proportionality coefficient of an actual linear geometric size and the front image linearity; and (5) measuring actual distance between any two points in the photo image or a frame of picture, and multiplying the actual distance by the proportionality coefficient eta to obtain actual distance between two corresponding points of the human body. The invention also discloses a method for customizing a spectacle frame. In the invention, the transverse maximum length of the eye black part is measured to acquire the proportionality coefficient of an actual size and an image size, and thus absent measurement of any two points of the human body and an image or video comprising the human body can be carried out; and the data calculation is accurate, and the application is wide.

Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a method for measuring the actual distance of a human body based on the cornea, and customizing spectacle frames according to the method for measuring the actual distance of the human body. Background technique [0002] When customizing clothes or glasses, etc., it is necessary to actually measure the distance between two corresponding points on the human body. Taking glasses as an example, the glasses are mainly composed of lenses and frames. Spectacle frames also need to be customized according to different facial structures such as interpupillary distance, nose bridge height and width, and the distance from the top of the cornea to the plane of the top of the ear. Existing spectacle frames are mass-produced by the factory according to common parameters, and customization cannot be realized. The customized solution must be that the spectacle wearer goes to the opti...

AI Technical Summary

Problems solved by technology

Existing spectacle frames are mass-produced by the factory according to common parameters, and customization cannot be realized. The customized solution must be that the spectacle wearer goes to the optician shop or optician center to complete the selection of spectacle frame size parameters and manual adjustment according to his own feeling. It takes a lot of time for the lens maker, and manual measurement sometimes causes parameter errors, and the adjusted frame makes the final glasses uncomfortable to wear.
