Method and device for measuring ring size

Abstract

The invention discloses a ring hand inch measurement method comprising the following steps that a finger to be measured selected by a user is received and the shape of the finger to be measured is determined; if the finger to be measured is selected to be the thumb, the finger to be measured is vertically and laterally pressed on a hard plane according to the determined shape of the finger to be measured to measure the width of the maximum knuckle, wherein the maximum knuckle is the knuckle closest to the nail; and if the selected finger to be measured is not the thumb, the corresponding measurement mode is selected according to the determined shape of the finger to be measured. According to the method, the limitation, the complexity and low effectiveness of the hand inch measurement flow in the conventional technology can be solved, and ring hand inch measurement is completed through digital equipment so that the measurement flow can be simplified, and the method has application universality, usability, efficiency and flexibility. The invention also discloses a ring hand inch measurement device.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a method and device for measuring the size of a ring. Background technique [0002] In the prior art, a tool for professionally measuring the size of a ring, that is, a model ring marked with a size number is used to try it on, so as to determine the size of the finger suitable for wearing the ring. Among them, hand-inch refers to the different numbers of rings due to different diameters. In China, the numbers under the Hong Kong ring measurement standard are generally adopted. In addition, there are different measurement standards in Europe, the United States, Japan and other countries, referred to as Oudu and Meidu. , day, etc. If there is no special tool for measuring hand size, the general method is to measure the circumference of the finger where the ring is worn, then get the inner diameter of the ring, and then convert it into ring size.

Problems solved by technology

[0003] The disadvantages of the above method are: professional tools for measuring the size of the ring are required, and professional tools are not convenient to carry around at any time; the method of circumference conversion requires soft materials as auxiliary measuring tools, such as thread or paper, although they are easy to obtain. But it increases the cumbersomeness and error of measurement; in the end, any method cannot realize the operation of measuring hand size only with the digital equipment used in daily life.
