Foot measurements from 2D digital images

Abstract

Foot measurements play an important role in the design of comfortable footwear products. This study proposed a non-invasive and efficient means to obtain foot measurements from 2D digital foot images. The hardware of the proposed image-based measuring system was easy to set up and the developed measuring system was tested for 9 foot measurements with ten male subjects who were also manually measured. The comparison between foot measurements from the image-based and the traditionally manual measured systems showed that there were no significant differences between two systems on 8 out of 9 foot measurements. The errors on foot measurements from the image-based system were also analyzed and discussed. The proposed image-based system under further improvements may be applied into the online sales of shoes, especially customized shoes.
