The invention concerns a device and a method for measuring the position and/or orientation of a first element (3) with respect to a second element (2) of a vehicle, on which this first element (3) is mounted in a movable manner, with the aid of an optical measuring system with at least one camera unit (1), whereby at least three references (4,5,6), not laying on a strait line, are provided on one of these elements (3) such that these references (4,5,6),can be perceived by the camera unit (1). Said camera unit (1) is mounted fixed with respect to the other element (4) and the position of said references (4,5,6) is measured with said optical measuring system for successive positions and/or orientations of the element (3) on which these references (4,5,6) are provided.
L'invention concerne un dispositif et un procédé permettant de mesurer la position et/ou l'orientation d'un premier élément (3) par rapport à un second élément (2) d'un véhicule sur lequel ledit premier élément (3) est monté de manière mobile. Les mesures s'effectuent au moyen d'un système de mesure optique comprenant au moins une unité caméra (1), au moins trois repères (4, 5, 6) non alignés étant tracés sur l'un de ces éléments (3), de telle sorte que ces repères (4, 5, 6) puissent être perçus par l'unité caméra (1). L'unité caméra (1) susmentionnée est montée de manière fixe par rapport à l'autre élément (4); la position desdits repères (4, 5, 6) étant mesurée au moyen du système de mesure optique pour les positions et/ou les orientations successives de l'élément (3) sur lequel les repères (4, 5, 6) sont tracés.
