| 摘 要： | 本文开发了一个新型的粒子图像速度粒度场仪(PIVS)查询系统,提出了一条新的PIVS配对前预处理思路。该查询系统以DPIV粒子图像为处理对象,结合图像处理技术,采用灰度频数统计法及灰度差分法分别获取速度和粒径信息,实现了速度粒度的同场测量,并利用模拟粒子图像对基于灰度差分法查询算法进行了图像检验。检验结果表明,该查询算法能很好的处理各种模拟图像,并且有很高的计算精度及良好的运算效率。

| Abstract: | This paper proposes interrogation algorithm for Particle Image Velocimetry & Sizer (PIVS) and a new preprocessing method of PIVS images before pairing.Combining with image processing technology,interrogation algorithm of Grey-scale Difference Method(GDM) is developed and valued by simulated DPIV auto-correlation images.Using grey-scale statistic method and GDM, velocity vector and particle size are acquired simultaneously.The result shows that the proposed algorithm can process different simula- ted particle images with high accuracy and meet the need for the real time operation. |
