We propose the new PIV image processing method to apply to the cavitation flow field. Two CCD cameras take each image shots of good quality utilizing the difference of the scatter light intensity between the seeding particles and the bubbles. From the image of the seeding particles, the cavitation aspect information such as the void fraction and the cavity boundary is obtained by using the binary process of the light intensity. From both images of the seeding particles and the bubbles, two velocity informations are obtained individually inside or outside area of the cavity by using the cross correlation method and composed into one. For the evaluation of this PIV measurement and processing, the experiment was carried out about the wake vortex cavitation flow behind a wedge. And also, the cavity area and the void fraction map, the vector map and the vorticity map were discussed in detail
