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

Embodiment 1

[0050] A method for measuring the actual distance of the human body based on the cornea image, which is the measurement of the parameters of the absent human body, please refer to figure 1 As shown, it includes the following steps:

[0051] Step 1. Obtain a photographed image with dark eyes or capture a frame with dark eyes from a video; there is no limit to the angle of shooting images or videos, as long as the captured images or a certain frame of the video are guaranteed It has the black part of the eye (here the image of the black part of the eye can be approximated as the image of the cornea). However, it should be noted that in this application, it is only necessary to obtain an image or picture with a black eye part in the photographed image or video, but due to the problem of the shooting angle, in a frame captured in the photographed image or video, if If there are two dark eye parts, select the larger one, and the selection process can be completed by a computer or ...

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...
