论文摘要
我们提出了一个开源MATLAB软件包，标题为“ OpenPiv-Matlab”，用于分析粒子图像速度计（PIV）数据。我们使用其他工具扩展了PIV分析，用于后处理PIV结果，包括从浸入浸水（虚张声势或精简）身体后面的PIV数据中估算Aero/流体动力的估计。本文介绍了包装的详细说明，涵盖了三个主要部分：从成对的图像（OpenPiv-Matlab），基于速度和时间分析工具箱）（空间和时间分析工具箱）的二维组件速度字段，空间和时间流量分析，以及唤醒流量分析以及力流量分析以及力估计（GetWake toolbox）。使用在风隧道中自由飞行的欧洲Starling（\ emph {sturnus fulgaris}）的时间分辨PIV唤醒数据证明了具有各种后处理能力的完整分析。
We present an open-source MATLAB package, entitled OpenPIV-Matlab, for analyzing particle image velocimetry (PIV) data. We extend the PIV analysis with additional tools for post-processing the PIV results including the estimation of aero/hydrodynamic forces from the PIV data of a wake behind an immersed (bluff or streamlined) body. The paper presents a detailed description of the packages, covering the three main parts: generating two-dimensional two component velocity fields from pairs of images (OpenPIV-Matlab), spatial and temporal flow analysis based on the velocity fields (Spatial and Temporal Analysis Toolbox), and wake flow analysis along with the force estimates (getWAKE Toolbox). A complete analysis with a variety of post-processing capabilities is demonstrated using time-resolved PIV wake data of a freely flying European starling (\emph{Sturnus vulgaris}) in a wind tunnel.
