通过使用标准的粒子图像测速算法的询问窗口被放置在一个结构化的网格和空间分辨率是手动选择。显然，更好的方法是自动选择处理参数，并使它们局部适应接种密度和流动条件。本文介绍了一种自适应空间分辨率方法，并通过使用合成和真实的图像进行性能评估，清楚地显示了该技术的优点。
By using standard particle image velocimetry algorithms the interrogation windows are placed on a structured grid and the spatial resolution is manually chosen. Clearly, a better approach is to choose automatically the processing parameters and to adapt them locally both to the seeding density and flow conditions. An adaptive space resolution method is introduced herein and the performance assessment performed by using both synthetic and real images clearly shows the advantages of the technique.
