摘要
現今消費者選購鞋時，往往不斷試穿，方能找到一雙適合個人腳形的鞋，又常常買回家後發現並不適合個人腳形。故選鞋前如果能先量測個人的腳型尺寸，對選購鞋有極大幫助。數位化時代來臨，數位量測科技不斷進步，得以幫助足形量測。傳統全足形量測利用石膏繃帶，不但費工耗時，而且容易使患者感到不舒適。目前數位式的量測系統主要來自國外，3D足型量測設備價格昂貴，於國內無法使足形量測普及化。本論文研究目的為開發一套低成本「3D全足形量測系統」，運用「線雷射」掃瞄技術，結合格雷碼(Gary Code)進行位置定位，再經數位攝影機拍攝的影像，經過分析處理，完成點雲資料建立，最終完成受測者之全足形三維資料之量測。本研究開發之機台，其所使用的電子元件與材料，皆取自一般市面，主結構由鋁擠、鋁板、以及強化玻璃作結合，待測物直接放置於平台上量測。 機台尺寸為840×400×350 mm，可量測最大範圍為500×180×150 mm，單程掃瞄時間少於20秒，X軸、Y軸、Z軸方向量測解析度約為1 mm。

A Consumer wants to choose a pair of shoes that fits his foot shape. However, a consumer often discovers that shoes do not fit well with his foot. To solve this problem, this research aims to develop a "3D whole foot shape measurement system". We use line Laser scanning technology and Gray Code to locate position. Images taken from webcams are processed to create three-dimensional models, As a result, foot models are built. With the advance of the digital measuring technology, the process of measuring can be speeded up. In the past, whole foot shape measurement requires the use of plaster bandages. This requires a lot of time and makes a patient feel comfortable. The existing 3D whole foot shape measurement equipments are expensive. As a result, it is difficult to promote foot shape measurement in Taiwan. The goal of this study is to develop a low-cost line laser scanning system to measure whole foot shape. The equipments used in this research project three laser lines on the glass surface, and then captured by three webcam. The captured images are analyzed using laser Gray Code to determine the stroke position. Image distortion in each taken images are corrected to build three-dimensional models. The electronic compartments of the measuring equipment used in this study are commodity hardware available in the general market. The equipment consists of aluminum extrusion, aluminum, and tempered glass for binding. The analyte can be placed directly on the platform. The dimensions of this machine are 840 × 400 × 350 mm. Its maximum measuring size are 500 × 180 × 150 mm. The one-way scan time is less than 20 seconds. The measurement resolutions of X-, Y-, and Z- axis are 1mm.
