Measurement of the actual distance of the human body and the method of customizing spectacle frames

Abstract

The invention discloses a method for measuring the actual distance of a human body based on an eye cornea image, which comprises the following steps: Step 1. Acquiring a frontal photographed image with black parts of eyes or intercepting a frame of frontal pictures with dark parts of eyes from a video Step 2, detect and locate the black part of the eye; Step 3, determine the horizontal maximum length of the black part of the eye; Step 4, determine the proportional coefficient between the actual linear geometric size and the linearity of the frontal image; Step 5, measure any two in the photographed image or a frame The actual distance between two points can be obtained by multiplying the actual distance by the proportional coefficient η to obtain the actual distance between the corresponding two points of the human body. The invention also discloses a method for customizing the spectacle frame. The invention measures the maximum lateral length of the dark part of the eye, and then obtains the actual size and the proportional coefficient of the image size, so that the alibi measurement can be performed on any two points in a human body, an image including a human body, or a video, and the data calculation is accurate and widely used.

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...

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.
