状扫描和区域搜索辨识条纹顺序的方法研究

本文提出了一种自动辨识条纹顺序的方法。它使用简化的Otsu算法获得阈值，然后在45°的范围内对干涉条纹的位置进行搜索，最后由区域搜索技术辨识不同的条纹。实验结果表明，本方法能可靠地获得近似45°到90°的干涉条纹顺序。

A method for automatically identifying the order of fringe pattern traces is presented. It uses the simplified Otsu algorithm for obtaining the threshold, the angular scan in the range of 45° for searching the trace positions, and the zone search technique for identifying different traces. Experimental results show that the proposed method may reliably obtain the order of fringe pattern traces orientating from almost 45° to 90°.
