The OPERA experiment, designed to perform the first observation of ν_μ→ν_τ oscillations in appearance mode through the detection of the τ leptons produced in ν_τ charged current interactions, has collected data from 2008 to 2012. In the present paper, the procedure developed to detect τ particle decays, occurring over distances of the order of 1 mm from the neutrino interaction point, is described in detail. The results of its application to the search for charmed hadrons are then presented as
