Dataset for Generating Controlled Gust Pertubations Using VortexRing

These data characterize the spatial and temporal evolution of a vortex ring, used here as a well controlled gust to perturb freely flying insects. In order to get this data, we first seeded the flow using fog particles for flow visualization and then used high-speed cameras to record the flow images for a long time. The images were then processed to get the position of the fog in each frames. Similarly, we used high-speed cameras to obtain kinematics of freely flying insects in controlled environment.

本数据集表征了涡环（vortex ring）的时空演化过程，本研究中将其作为可控阵风以扰动自由飞行的昆虫。为获取该数据集，我们首先通过雾粒对流场进行播种以实现流动可视化，随后使用高速摄像机长时间记录流场图像。随后对采集到的图像进行处理，以提取每帧图像中雾粒的位置信息。类似地，我们通过高速摄像机记录了可控环境下自由飞行昆虫的运动学参数。更多细节请参阅ReadMe.txt文件。
