Wind medium seed tracing method for indicating sub-hectometer level flow characteristics and wind medium seed preparation method

The invention discloses a wind medium seed tracing method for indicating sub-hectometer level flow characteristics and a wind medium seed preparation method. According to the flow field measurement technology provided by the invention, two-dimensional or three-dimensional measurement of the flow field at the sub-hectometer level can be realized; on a large flow field measurement scale, the flow field is traced by using seeds of natural plants propagating along with wind, and two-dimensional or three-dimensional flow field vector data of an observed area is obtained by means of illumination of a corresponding large-scale flow field area, continuous image acquisition of a camera, post-processing and reconstruction calculation of acquired images and the like. 本发明公开了一种指示亚百米级别流动特征的风媒介种子示踪方法及风媒介种子制备方法。本发明所提出的流场测量技术可以实现对流场在亚百米级别上的二维或三维测量；在大的流场测量尺度上，利用自然植物的随风传播的种子，对流场进行示踪，依托对相应大尺度流场区域的照明及摄相机的连续图像采集，对所采集图像的后处理及重构计算等，从而获得所观测区域的二维或三维流场矢量数据。
