摘要
本文在对两种传统PIV算法进行深入分析的基础上 ,融合了它们的优点而发展了一种新的速度提取算法—预估搜索法 ,并给出了算法的具体实现步骤。人工及真实图像实验均表明该法具有求解速度快。
Based on the thorough analysis of two conventional PIV algorithm,a new velocity extracting methods called “Preestimate Searching Algorithm” is presented in this paper which combines the superiorities of the two conventional PIV algorithms and provides the realization procedure of this new algorithm.Both the synthetic images and real PIV images experiments show that the new algorithm has the advantages of high precision and fast computing speed.
