The paper describes a special algorithm for reconstructing the tracks of charged particles in the central part of the track system of the SPD experiment being built at the NICA collider. The program consists of a procedure for searching for track candidates in a two-dimensional space, followed by adding information about the longitudinal component of the track. The track parameters were estimated using a Kalman filter, which takes into account energy losses and multiple scattering during the passage of a charged particle through a substance. The program demonstrated high efficiency of track reconstruction and was added to the SPD experiment software. Keywords: SPD experiment, Hough transform, track reconstruction, Kalman filter, Monte Carlo simulation.
