Particle Image Velocimetry (PIV) offers many advantages for the study of fluid flows. The PIV has two processes, i.e., the image capture with visualization and the image analysis. In order to evaluate the image analysis system for the PIV, the Japanese PIV Standard Project (JPIV) proposed the standard images for PIV. The developed PIV standard images are distributed using the Internet, (http://www.vsj.or. jp/piv/) and CD-R. Using the PIV standard images, the sub-pixel accuracy on the PIV and PTV were evaluated. The accuracy was confirmed to be about 0.2 pixel/interval for both of PIV and PTV.
