The invention relates to a sheet-of-light imaging method. A first (114) and a second measuring light projection onto a surface of an object (110) to be measured can be unambiguously identified by a camera (106) as the first (114) or second measuring light projection if a supporting device (108) operates the camera (102) and/or the measuring light projectors (102; 104) in such a manner that after every sheet-of-light imaging of the camera (106) either the first (114) or the second measuring light projection is visible for the camera (106). Unambiguous identification allows evaluation by means of one camera (106) of a plurality of measuring light projections that physically overlap and that are not exactly aligned in relation to each other.

Dans le cadre d'un procédé de coupe optique, une première (114) et une second projection de lumière de mesure sur la surface d'un objet à mesurer (110), peuvent être identifiées par une caméra (106) de façon univoque en tant que première (114) et seconde projection de lumière de mesure, en la présence d'un dispositif d'assistance (108) qui fait fonctionner la caméra (102) et/ou les projecteurs de lumières de mesure (102; 104) de sorte qu'à chaque prise de coupe optique de la caméra (106), soit la première (114), soit la seconde projection de lumière de mesure est visible de la caméra (106). La possibilité d'identification univoque permet l'évaluation au moyen d'une caméra (106), de plusieurs projections de lumière de mesure qui se recouvrent dans l'espace et ne sont pas orientées avec exactitude les unes par rapport aux autres.
