PROCESS FOR THE TRAJECTOGRAPHY OF OBJECTS AND DEVICE FOR PERFORMING THIS PROCESS

The invention relates to a process for obtaining trajectories of moving objects, by optimizing at least one criterion from the physics of the phenomenon observed and comprising the following stages: a stage of recording signals (10), a stage (11) of extracting given parts of the signals, a stage (12) of subdividing the group of parts of the signals previously extracted into classes, each class representing a potential trajectory, a stage (13, 14) of selecting a subset of classes satisfying constraints linked with the observed network type, a stage (15) of selecting from among the classes representing the potential trajectories those satisfying the constraints, so as to obtain "real" trajectories of the objects. The invention also relates to a device for performing this process.
