This paper is development of Surface Flow PIV for velocity measurement of surface flow. The new Velocity measurement method for surface flow using video-taped images is presented. Velocity distributions are calculated by the correlation method after the transformation of images to the non-distorted ones. The method to transform oblique-angled images to normal ones as well as its accuracy is discussed in detail. In this study, we carried out velocity measurement of an ocean current velocity distribution of saemangeum sea-wall model using Surface Flow PIV.
