PTV (Particle Tracking Velocimetry) has been limitedly used for the measurements of flow fields because there have been interpolation data loss which is inevitable to PTV in principle. In this paper, a hybrid PTV algorithm which eliminates interpolation data losses has been constructed by using an affine transformation. In order to evaluate the performances of the constructed hybrid PIV algorithm, an artificial image test was made using the Green-Taylor vortex data. The constructed algorithm was tested on the experimental images of the wake flow (Re = 5,300) of a rectangular body (6cm × 3cm), through which its excellence was demonstrated.
