Abstract
Pseudocolor image processing and characteristic pattern method were applied to PIV system for improving PIV accuracy in this paper. Characteristic pattern of the PIV images is extracted and is used as image cognition. However, this method generated false velocity vectors due to analogy of characteristic pattern of PIV images. As a new method, it is proposed to calculate the velocity vectors from the correlation of characteristic pattern of pseudocolor PIV images. It is found that pseudocolor image processing and characteristic pattern method are effective in PIV system.
