An algorithm of track recognition in an uniform magnetic field is proposed for the drift straw tube detecting system of solenoidal geometry. The problem solution is given for (x,y) plane perpendicular to the magnetic field. Our algorithms is elaborated on the basis of (1) sequential histogramming method, which is, in fact, a modifications of the Hough transform and (2) a modification of deformable template method following by a special procedure of parameter correction. Being tested on simulated events our method shows satisfactory efficiency and accuracy in determination of particle momenta.
