Development and Application of Image-base Plantar Measurement System

Abstract

The foot pain affects daily life function about 14-4b2% of adults over the age of 45 years old, since feet bear all the weight of the body. The most foot problems come from a great impact on the human body. It affects not only bone structures, but also the organs. Plantar information can be checked through the plantar pressure and arch index. The plantar pressure distribution is related to the walking balance, while the arch index can understand the foot bone structure. The paper aims to develop a system of plantar self-detection which is economical and easy to carry and operate. The system has built up two parts: one is the image capture equipment; another is the data analysis software. The portable scanning platforms can obtain high-resolution image, scanning work area is 216x356mm which the resolution is 1200dpi image. It only needs 10 seconds, using the wireless transmission to the plantar image through the pad for data analysis, calculated the plantar pressure distribution and arch index. The whole system price is less than one-tenth of the market selling pressure pad, providing a general system which is designed for plantar self-detection.
