設計一低成本之扁平足測量系統

在台灣扁平足是一個倍受關切的問題；在小兒骨科特別門診裡，每天的門診中總是有大約五至十位的父母因為擔心他們的兒童是否為扁平足而來求診。然而這些病患當中，大多是因為擔心扁平足影響了兒童未來的成長或運動能力，而來請教治療的方針。但過去的檢測方式皆須花費較長的時間或較多的程序，甚至必須照射X光做檢測，相當的繁複與不便，因此如何將檢測扁平足的方式做改善，使其方式改善為簡易、快速且準確度高，並可普及到各醫療院所，供所有人做檢測是一項非常必要的改善。本研究運用低成本的硬體裝置以及Visual Basic軟體程式設計，建構出一套低成本之扁平足測量系統，透過Web cam及綠光LED拍攝出腳底影像，之後經由設計完成的Visual Basic軟體來測量腳底面積及腳底部位深淺程度，並利用足弓指標方式運算出正確的足弓指標值做判斷，目的在於使所有人可以方便、快速及準確的測量出自己是否為扁平足的患者。

Flatfoot is a problem of much concern in Taiwan;5 to 10 parents have to worry about whether their children seeking treatment for flat feet from the daily outpatient special clinic of pediatric orthopedics. However, among these patients, mostly worry about flat feet affect a child's future growth or athletic ability, from consult treatment guidelines. Past detection methods are required to take a long time or more procedures that may require radiation X-ray detection, quite complicated and inconvenient, and therefore how to detect flatfoot way to do to improve, to improve its way to simple, fast and accuracy, and can spread to health care facilities for everyone to do testing is a very necessary improvement. In this study, low-cost hardware devices, as well as Visual Basic software program designed to construct a low-cost measurement of flatfoot, foot images shot through the Web cam and green LED, through the Visual Basic software design is completed to measure the soles of the feet area and the foot part of the degree of difficulty, and the use of arch index to calculate the arch index values to make a judgment, aimed at all convenient, fast and accurate measure of whether patients with flatfoot.
