Human body upper limb zone shape classification method based on main component analysis and layered clustering

Abstract

The invention relates to a human body upper limb zone shape classification method based on main component analysis and layered clustering. The method includes: collecting human body data to build a human body database; preliminarily selecting human body part data related to upper limb zone shapes, and determining basic variables according to the linear dependence of the rest human body part data and the human body part data related to the upper limb zone shapes; using a main component analysis method to select variables representing the upper limb zone shapes from the basic variables; using alayered clustering method to further determine arm anteversion angle, upper arm circumference and shoulder length to serve as the variables for representing the upper limb zone shapes; classifying theupper limb zone shapes according to the arm anteversion angle, the upper arm circumference and the shoulder length. By the method, the upper limb zone shapes can be directly and effectively classified.

Description

technical field [0001] The invention relates to the technical field of clothing structure design, in particular to a method for classifying the shape of human upper limbs based on principal component analysis and hierarchical clustering. Background technique [0002] The sleeve is the clothing structure that covers the upper limbs (that is, the upper limbs of the human body and its related parts), and is an important part of the clothing. Whether its structure is reasonable or not plays a decisive role in the overall effect of the clothing. The shape of the upper limbs is an important factor affecting the structure of the sleeves, and meeting the shape and movement needs of the upper limbs is the first prerequisite for the design of the sleeves. Therefore, the correct evaluation of the shape of the upper limb belt is helpful to improve the design of the sleeve model structure, and at the same time, it is also conducive to the development of functional protective gear coverin...

AI Technical Summary

Problems solved by technology

[0003] In the current research on the structural design of clothing and related functional protective gear, the upper limb shape is mainly studied through a few indicators such as total arm length, upper arm circumference, and arm inclination angle, and the shoulder and armpit, which are closely related to the upper limb, are not involved. The influence of human body parts on the shape of the upper limbs cannot directly, effectively and comprehensively express the shape of the upper limbs
