The invention concerns a method for determining the trajectory of a point of a moving object provided with markers, which comprises: acquiring (32) a scatter diagram, by means of a motion capture system, at a plurality of successive moments in time; selecting (56), from the acquired diagrams, points belonging to a trajectory of a given marker; and in which the selection of a subsequent point of the trajectory at a moment in time t+1 comprises: estimating the coordinates of the subsequent point, by means of an extrapolation function taking as argument the coordinates of a plurality of preceding points of the trajectory; identifying the point in the diagram acquired at the moment in time t+1 in which the measured coordinates are closest to the estimated coordinates, and adding the point identified in this way to the sequence of points of the trajectory. |
