摘要

本文研究旨在於開發一套低成本、易操作、速度快、掃描精度高的逆向雷射掃描系統，運用自製開發系統移動平臺、雷射掃描系統及開發之量測軟體，將腳底置於系統機臺上，利用雷射光源自下面投射至腳底上，透過CCD攝影機作連續擷取影像，藉此來拍攝腳底資訊上的座標資訊。
本設備可擷取腳底圖面資料，以短時間掃描和高準確性計算點位座標，掃描出各種腳底曲面資料，之後可輸出做客製化的足弓墊、鞋墊、鞋底等產品項目。運用影像三角測量技術量測座標資訊，並結合光學技術與開發的雷射掃描模組，最終達成低成本、高穩定性與速度快的腳底逆向雷射掃描系統。

This research aimed to develop a low cost, easy to operate, fast, and high precision reverse laser scanning system. System in this research utilized a self-developed and self-manufactured system moving platform, a laser scanning system, and self-developed measuring software. Coordinate data of the soles of feet were captured by placing the feet on the machine, projecting laser light onto the soles from underneath, and then using the CCD camera to take a series of photos.
The equipment is capable of capturing graphical data of the soles of feet. It can perform quick scan and calculate coordinates with high precision in order to generate various information of the curved surfaces of the soles of feet. The information can then be exported and used in producing customized foot-arch pads, insoles, soles of shoes, and other products. Thus, a low-cost, stable, and fast reverse laser scanning system was realized by utilizing image triangulation technique to measure coordinates and by integrating optical technology with a self-developed laser scanning module.
