Labview和matlab在現代光測圖像進行中的應用
摘要
現代光測技術是近年來發展起來的一種新技術，它可用于物體的粗糙度測定、變形測量和振動分析。現代光測技術主要包括全息幹涉、雲紋幹涉和散斑幹涉。
本文基于 LabVIEW 與MATLAB 開發了現代光測數字散斑圖像處理系統，首次把虛拟儀器技術引入現代光測領域。系統基于數字散斑幹涉技術，在LabVIEW 環境下進行圖像采集，并調用MATLAB 實作圖像處理。系統可擴充應用于全息和雲紋幹涉測量。本文的主要研究工作包括：(1)在現代光測領域引入虛拟儀器技術，建立光測虛拟儀器系統，實作圖像的采集和處理；(2)研究空域和頻域的濾波技術，提出處理現代光測圖像的最佳濾波方法，得到高品質的圖像處理結果。
