Abstract

L'invention part d'un dispositif de mesure d'éloignement (10), et plus particulièrement d'un dispositif de mesure d'éloignement manuel, comportant une unité de mesure d'éloignement (12) prévue pour saisir au moins une valeur de mesure d'éloignement dans au moins un sens de mesure (24). Il est proposé d'avoir au moins une unité de formation de groupes (34) prévue pour associer une valeur de mesure d'éloignement à l'un d'au moins deux groupes de valeurs de mesures. L'invention propose par ailleurs un procédé de mesure d'éloignement selon lequel des données de mesures d'éloignement de l'unité de mesure d'éloignement et/ou des données d'orientation d'une unité de détection d'orientation et/ou de données de position absolue d'une unité de détection de valeur absolue sont transmises à une unité de visualisation. Plus particulièrement, une valeur de l'éloignement mesuré peut être associée à un groupe de valeurs de mesures.
