The invention relates to a method for selecting measured eye position data which is suitable for further processing, from a stream of measured data associated with at least one eye. Said data relate to a proband. The data stream is supplied by an eye position measuring device within a certain time interval. The measured data are initially stored. Individual data from the data stream which occur within a predetermined window range are then combined to form clusters. Each cluster is allocated to a group respectively, the first group having the cluster with the temporally first measuring data and the remaining clusters being allocated to further groups according to the chronological order of the measured data. Finally, the group containing the most measured data is selected as suitable for further processing. The invention also relates to a device for carrying out the inventive method.

L'invention concerne un procédé permettant de sélectionner les données de mesure, relatives à la position des yeux d'un patient et appropriées au traitement ultérieur, dans une série de données de mesure associée à au moins un oeil et fournie par un instrument de mesure de la position de l'oeil dans un certain intervalle de temps. Les données de mesure sont d'abord mémorisées puis les données de mesure individuelles de la série, situées dans une zone fenêtre prédéterminée, sont regroupées en ensembles. Ensuite, chaque ensemble est associé à un groupe, le premier groupe présentant l'ensemble ayant chronologiquement la première date de mesure et les autres ensembles sont affectés aux autres groupes selon l'ordre chronologique des données de mesure. Enfin, le groupe choisi comme groupe approprié au traitement ultérieur est celui qui contient la plupart des données de mesure. L'invention concerne également un dispositif permettant de mettre en oeuvre le procédé selon l'invention.
