The pressure field data based on PIV contributes understanding flow field although PIV based pressure field has uncertain because of its boundary condition and assumption of two dimensional flow. Thus we did direct pressure measurement experiment and compared with PIV based pressure field in vortex ring impinging flow field. Focusing on the time span between vortex ring impinging and rebounding, PIV based pressure is match with direct measurement pressure. But focusing on the value of pressure coefficient, PIV based pressure is not match with direct measurement pressure. So if the PIV based pressure is used as quantitative data, it needs more consideration.
