在二维 PIV的图像处理中 ,本文从互相关技术出发 ,建立了相应的连续两幅图像之间的粒子对应方法 ,提出了误对应速度向量的判断和消除准则。通过粒子的标定、粒子的对应、误对应粒子速度向量的判断和消除等步骤建立了相应的二维射流的 PIV图像处理方法。利用日本可视化协会 (VSJ)提供的二维射流标准图像的处理 ,可以发现本文建立的方法是切实可行的 In the two-dimensional PIV image processing, this paper sets out the corresponding particle correspondence method between two consecutive images based on the cross-correlation technique and puts forward the judgment and elimination criteria of the mismatch velocity vector. The corresponding PIV image processing methods of two-dimensional jets are established through the steps of particle calibration, particle correspondence, and mistaken correspondence of particle velocity vectors. Using the two-dimensional jet standard image processing provided by Japan Visualization Association (VSJ), we found that the method established in this paper is feasible
