Abstract:	本論文將中國文化大學實體模擬實驗室之三維雷射掃描平台系統精進，量測文化大學後山之風力發電機葉片，獲取葉片3D外型，分析其剖面翼型效率，提升風機系統效益。利用逆向工程方式，使用非接觸式三角量測法，配合系統光學尺定位精度改良，加強平台移動準直度，提升影像掃描取像率及系統性能，並降低3D實體量測誤差及成本使其進入產業界更具競爭力。本平台系統依設計自製一長行程線性量測平台，其包含3米移動機構、光學尺、3D取像攝影機和單線雷射、PID控制器、直流無刷馬達及傳動等四項次系統。本量測系統特色為：配合完整的馬達傳動和PID光機電控制整合介面，可快速掃描量測0.5米至2米複合材料之風機葉片，搭配單線雷射頭和非接觸式光學探頭取像，利用NI LabVIEW將影像光學探頭所擷取影像二值化、細線化技術處理及曲面資料補償，最後利用曲面擬合得到葉片三維外型。在電腦中將葉片切取剖面，可透過軟體計算葉片各部位之空氣動力，獲得風力發電機所需性能數據，將重建完成之葉片外型與葉片資料做比對，可以提出葉片外型性能改善方案，提升風力發電機發電效率。 This thesis is aimed to improve the performance and efficiency of three-dimensional laser scanning platform system by cheap components and high accuracy laser Doppler displacement meter (LDDM). A full-scale three-dimensional profile measurement system with an innovative optical setup for measuring the geometric shape of large wind-turbine blades in high accuracy is included in this thesis With reverse Engineering analysis, we have improved the non-contact triangulation measurement method with Optical scale. Through making a better linear positioning accuracy to achieve, better 3D image pixel and system performance, with less 3D measurement costs, this system presents a better competitive strength in industry. This system is based on a self-made long stroke linear measurement platform including 3 meter movement mechanism, optical scale, 3D image capture camera, single-line laser, PID controller, brushless DC motor and transmission system. The characteristic of this measuring system contains: Completely optical and electrical motor drive and PID control integration interface, which expedite the scan measurements of 0.5 to 2 m composite wind turbine blades, with single line laser head and non-contact optical sensor to capture images, we use LabVIEW image optical probe to achieve the captured image thresholding, thinning and to regulate surface data. Finally, the shape of three-dimensional curved blades and determined. We then make the blades and calculate aerodynamic through the various parts of the software to get the wind turbine performance data.
