| 摘 要： | 本文应用数字图象处理技术，判读流场示综粒子迹线照片．从而给出瞬时二维流场速度分布，为了保证足够的信息量，即迹线条款，图象处理技术中除必须有自动识别单条迹线位置、大小、方向的能力外，还必须有判别出多条迹线粘连的能力，最后由流场速度分布可以得到流函数等其它物理量。

| Abstract: | In this paper a more extensive application of image processing technigues onrecognizing particle track images and reconstructing the velocity distribution have been developed:(1)recognizing the position,length and direction of every single track image automatically;(2)seperating the adhesion and intersection between track images,so that the velocity vectors could been increased in a frame;(3)obtaining the stream function using the velocityvectors in a flow field. |
