摘要:

本文简述了多级网格迭代的图像变形算法的发展,重点介绍了多级网格迭代算法与图像变形算法匹配进行流场分析的基本原理及计算步骤。对算法的各主要环节进行了详细的讨论,包括相关系数峰值拟合方法,图形变形的速度场插值方法,亚像素点灰度插值方法,数据剔错方法及窗函数的应用。

This paper presents a brief introduction of the iterative multigrid image deformation method which combines iterative multigrid approach and image deformation approach for PIV. Major components of the method are discussed in detail, including correlation peak finding algorithms, interpolation schemes, velocity interpolation schemes, outlier detection schemes and weighting windows.
