Foot Shape Parameter Extraction and Classification of Male College Students Based on Three-Dimensional Scanning
The extraction and classification of foot features plays an important role in improving the fit and comfort of shoes.In order to accurately grasp the three-dimensional characteristics of young male college students'foot shapes,437 young male college students were tested by 3D laser foot scanners,and 19 original measurement indicators such as foot length,metatarsophalange circumference and arch height were statistically analyzed and factored,and K-means cluster analysis was used to achieve foot subdivision.The experimental results show that the height dimension of the foot shape has a large vari-ation and the length dimension has a small variation.Four principal components were extracted by factor analysis:length characteristic factor,width characteristic factor,height characteristic factor and other characteristic factor.According to the factor weight value,three variables of foot length,metatarsophalangeal circumference and arch height were extracted for K-means clustering analysis.The foot types of young male college students are divided into 7 categories,namely,short thin low arch type,long middle low arch type,short thin high arch type,long fat low arch type,short thin middle arch type,long fat high arch type,middle fat high arch type.The experimental results can provide a theoretical basis for shoemaking enterprises to produce comfortable shoes.
