The motion analysis plays an important role in the broad range of applications, such as visual feedback control, scene reconstruction and similar. In this paper the technique for 2D-motion analysis based on displacement vector determination is described. In our approach we have used the device called Fuzzy Pattern Comparator (FPC) and develop the fuzzy algorithm based on novel, cylindrical fuzLy sets of directions. Their introduction made the calculation of displacement vector direction and magnitude quite simple. The method was verfied experimentally and used in final positioning of the robot arm.
