Feature-based data structure for digital manikin

Abstract

A feature-based data structure of a digital manikin for describing the exterior features of a body comprises a plurality of feature points of the body, a plurality of girth lines, and a plurality of meridian lines. The girth lines pass through the feature points. Each of the meridian lines is formed by connecting the corresponding feature points respectively out of the girth lines. The girth lines of an arm of the body include an arm-hole girth, an elbow girth, and a palm base girth. The arm-hole girth passes through the shoulder end point, the front arm pit, and the rear arm pit. The elbow girth passes through the concave and convex points on the elbow girth. The palm base girth means the location where the size variation of the cross-sectional profile from the fore arm to the palm is the largest. The feature-based data structure for a digital manikin can sorts no-format cloud point data of three-dimensional human body scanning into structuralized data, faithfully describes geometrical shape of a human body in the simplest structure, simplifies human body data substantially, and can be applied to fields such as medical industry, human body measurement and costume manufacturing.

Description

technical field [0001] The invention relates to a characteristic data structure of an electronic mannequin. Background technique [0002] In an era when human values ​​are more valued, the design of products and the environment emphasizes that people are the main body, and human factors engineering and clothing design must be used in human body measurements become the key. Anthropometrics is an important research topic in human factors engineering, and anthropometric data is the most basic and important data for applying human factors engineering to various designs. In the past, our country lacked the anthropometric data belonging to the Chinese people, and most of them used foreign measurement data reluctantly, but this also included differences in body shape and body proportions. Therefore, it is urgent to develop a set of measurement databases belonging to each country. [0003] Anthropometric measurement is an important and complicated work, and only with objective and...

Problems solved by technology

However, the corresponding feature data structures for human arms, palms, legs, and feet are still lacking. Therefore, the inventors are still working hard to establish the feature data structure of the human body, hoping to be able to contribute to human factors engineering and human accounting. Tests have a revolutionary impact
