Abstract

Les modes de réalisation de la présente invention concernent le domaine de la détection automobile. La présente invention concerne un dispositif et un procédé d'étalonnage. Le dispositif d'étalonnage comprend un support, un appareil d'affichage et un appareil de projection de lumière, le support étant utilisé pour supporter et monter l'appareil d'affichage et l'appareil de projection de lumière ; l'appareil d'affichage est muni d'une extrémité de montage et d'une extrémité libre, qui sont situées à l'opposé l'une de l'autre, l'extrémité de montage étant reliée au support, et l'extrémité libre étant mobile par rapport à l'extrémité de montage ; et l'appareil de projection de lumière est utilisé pour projeter de la lumière sur un élément d'affichage flexible afin de former un motif défini, de manière à faciliter l'étalonnage d'un capteur destiné à être détecté sur un véhicule à détecter, le motif défini du dispositif d'étalonnage, qui est utilisé pour étalonner ledit véhicule, n'est pas formé au moyen d'une impression à l'encre, mais plutôt au moyen de l'appareil de projection de lumière qui projette de la lumière sur l'élément d'affichage flexible. Par conséquent, le dispositif d'étalonnage fourni dans les modes de réalisation de la présente invention peut prévenir efficacement l'inconvénient de l'effet d'affichage d'un motif défini qui peut être déformé par l'influence de l'environnement et du temps dans un environnement à haute température et humide.
