| 摘 要： | 对基于ＢＩＣＣ（ＢｉｎａｒｙＩｍａｇｅＣｒｏｓｓ－Ｃｏｒｒｅｌａｔｉｏｎ）算法的ＰＩＶ（ＰａｒｔｉｃｌｅＩｍａｇｅＶｅｌｏｃｉｍｅｔｒｙ）技术的原理进行了较详细的介绍．以封闭的正方形容器内的旋转流场为例，用计算机模拟检验了ＢＩＣＣ算法的可靠性，最后利用ＰＩＶ技术对阀腔内真实流场进行了测量．结果表明，ＢＩＣＣ算法能有效地进行图像粒子的识别，利用该算法可以得到精确的ＰＩＶ测量结果．

| Abstract: | An improved technique of PIV(Particle Image Velocimetry) and its principle based on BICC(Binary Image Cross Correlation) algorithm is described in detail. As an experiment, numerical simulation for the rotation flow within a square area is used to justify the algorithm, and then the real flow field in a valve chamber is measured by the technique. The experiment shows that BICC algorithm is effective for use in PIV and can give accurate results. |
