Abstract:

In order to improve fitting legs with the shaping products in women's leg compression treatment, 64 subjects were scanned using the [TC]2 non-contact three-dimensional digital body scanner, each with 160 data. The overall leg collimation was classified into 3 categories by interpolation simulation and cluster analysis, before the thigh and calve were classified according to the difference in frontal and lateral thigh morphologies and the different lateral projection points of the calves. A classification system of leg shapes was established based on the factor analysis method. Based on the above study, the relationship between female leg circumference and corresponding height was obtained, and the female leg shapes were divided into 6 categories and the corresponding leg classification specification table was summarized. This study provides a new method for categorization of leg shape for females, and offers basic data for the design of compression treatment and shaping products in different parts of legs of female.

Key words: three-dimensional digital body scanner, female leg shape, cluster analysis, factor analysis, leg shaping product
