Description

Breast volume measuring tool and method
Technical Field
The invention relates to the technical field of measuring accessories, in particular to a breast volume measuring tool and a breast volume measuring method.
Background
Most women wear a wrong size brassiere due to the measurement system recommended by manufacturers of bra at the time of purchase, which employs a combination of maximum chest diameter and maximum frame size diameter, rather than the actual chest volume that the brassiere will accommodate. In the clothing industry, the chest volume factor is closely related to the comfort of clothes, and only if the contour lines of the cups and the volume capable of being accommodated are matched with the breasts of a human body, the bra can give consideration to both comfort and beauty. The society has long been dedicated to find a convenient, fast, accurate and repeatable breast-shape volume measurement method, but because of the particularity of the shape structure and position of the breast, and the female breast is a dynamic body which changes about 10% -20% per month, the accurate and fast measurement of the breast-shape volume is still a problem at present.
The existing chest volume measurement is mainly divided into two types of mechanical measurement and digital measurement. The mechanical measurement refers to a technical means of directly measuring a human body by means of traditional manual and self-made tools and the like, the measurement mode is a contact type, and the measurement mode mainly comprises an empirical formula method, a Grossman-Roudner mold measurement method, a chest mold measurement method, a drainage volume measurement method and the like; the digital measurement refers to a technical means of operating and converting the obtained human body data through computer technology, and the measurement mode is non-contact, and mainly includes a 3D modeling method, a CT measurement method, an MRI measurement method and the like.
The empirical formula method is used for obtaining the volume of the breast by measuring the distance between straight lines or arcs between anatomical mark points on the surface of the breast and substituting the measured parameters into a formula.
The Grossman-Roudner mold measurement method is characterized in that a cone rolled by a transparent plastic sheet covers the chest, scales overlapped with each other on the edge of the plastic sheet are read to obtain volume data, although the method is convenient, the breast is not a regular cone, and the breast is compressed to a certain degree during measurement, so that the final data is influenced to a certain degree, and the accuracy is poor.
The chest mold measuring method is characterized in that a chest mold is manufactured by covering the chest of a testee with a material, and the mold is filled with water or sand after forming to calculate the capacity of the chest mold.
The displacement volume measurement method is to immerse the breast directly into a container filled with water, and estimate the volume of the specimen by calculating the volume or weight of the water displaced by the specimen, and the measurement method usually adopts a lying position or a kneeling position, so that not only the operation is complicated and the comfort level is low, but also part of testees may immerse the chest wall into the water too much, thereby causing great measurement errors.
The 3D modeling method needs to synthesize images with different angles, define the boundary of the breast and then calculate the volume of the breast, but the breast is a soft tissue organ, so the boundary is fuzzy, and the measurement cost is high and the time consumption is long.
CT measurements mainly introduce images into the relevant software to build a breast model to calculate volume, but with significant radiation.
Although the MRI measurement has high accuracy and repeatability, the measurement posture is uncomfortable and takes a long time, the scanning and the calculation take 68.0 +/-14.1 minutes and are expensive, and the MRI measurement is not suitable for dynamic chest volume measurement.
Therefore, how to conveniently, rapidly and accurately measure the chest volume and provide reliable chest volume parameters for the underwear industry is a problem to be solved urgently by those skilled in the art.
