The main advances and drawbacks of modern information technologies of tracer images processing are considered. A new method of evaluation of tracer images produced by 2d – PIV systems is proposed. The method is based on iterative building of reconstructed image on basis of the first frame in sequenced pare and finding the optimal assignment of node displacement from minimum divergence condition between reconstructed image and the second frame. The influence of different approaches within the viewing method on the accuracy of final result is explored. The perfection ways of information technology of tracer images processing is outlined.
