Single-foot standing test method and device

Abstract

The invention provides a single-foot standing test method and device. The invention belongs to the field of single-foot standing tests, and particularly relates to a method and a device for realizingan automatic, standardized and intelligent single-foot standing test by using a machine vision technology. According to the invention, the camera and the machine vision are used to carry out rule judgment and score measurement of a single-foot standing test; the limitation that a traditional single-foot standing test technology cannot carry out intelligent test is broken through, the camera and machine vision technology is introduced into the single-foot standing test method and device, the intelligence of single-foot standing test is achieved, the efficiency of single-foot standing test is improved, and the precision of single-foot standing score measurement is improved. Particularly, the method and the corresponding device work in a non-contact mode, the personal safety problem caused bythe fact that a traditional single-foot standing test device or instrument needs to work in an electrified mode is solved, and the safety of a tester in the single-foot standing test process is guaranteed.

Description

technical field [0001] The invention belongs to the field of one-leg standing test, and in particular relates to a method and a device for realizing automatic, standardized and intelligent one-leg standing test by using machine vision technology. Background technique [0002] The single-leg standing test, also known as the single-leg standing test, analyzes the core stability of the tester by recording the body balance time, and evaluates the tester's ability to control the balance of the body. It is an important physical quality indicator. The single-leg standing test requires the tester to close their eyes, open their hands, stand upright with their legs together, with their toes facing forward, and then lift one foot off the ground to start timing; in more demanding test scenarios, the calf where the foot needs to be off the ground is lifted Stand parallel to the floor and start timing when the raised shin is parallel to the floor. Most of the performance measurement of ...

AI Technical Summary

Problems solved by technology

The timing starts when one of the tester’s feet is off the ground, and the electronic device or device cannot judge whether the foot is really lifted or placed on other objects; in the scenario where the raised calf is required to be parallel to the ground to be timed, it cannot Determine if the raised calf is parallel to the ground

Electronic measuring equipment or devices can’t even judge whether the tester’s posture is standard, whether the tester’s eyes are closed or not, it still needs to rely on manual judgment, and different measurement personnel have inconsistent performance calculation standards due to inconsistent subjective standards for judging personnel posture, and the final measured results are inconsistent

[0005] The common problems of the above single-leg standing test methods and devices are that they cannot effectively judge whether the posture in the test process is standard or not, and the standardization of posture must rely on manual judgment. The automation and intelligence of the test are low, and the test efficiency is low. Big

In particular, the single-leg standing equipment or device based on electronic measurement needs to work with electricity, which poses certain dangers to the personal safety of testers.
