CA 2421354

Device for monitoring a lift door (12, 13, 14, 15) with a sensor (9) for detecting three- dimensional image information (16). The device comprises processing equipment designed in such a manner that the image information of detected images can be evaluated in order to recognise a deviation between the two images and thus to enable monitoring of the lift door (12, 13, 14, 15). The sensor (9) is a three- dimensional semiconductor sensor for detecting three-dimensional image information. It comprises a fight source (10) which is mounted in the region of the lift door (12, 13, 14, 15), which is to be monitored, in such a manner that the lift door (12, 13, 14, 15) is disposed at least partly in the illuminated region (17) of the light source (10). In addition, the sensor (9) comprises a sensor group (11) which is mounted in the region of the lift door (12, 13, 14, 15), which is to be monitored, in such a manner that it receives reflected light.

Dispositif de contrôle de porte de chargement basculante (12, 13, 14, 15) avec un capteur (9) pour détecter les données d'images tridimensionnelles (16). Le dispositif comprend un équipement de traitement conçu de manière à permettre d'évaluer les données d'images des images détectées afin de reconnaître une déviation entre les deux images et de permettre ainsi le contrôle de la porte de chargement basculante (12, 13, 14, 15). Le capteur (9) est un capteur à semi-conducteur tridimensionnel permettant de détecter des données d'images tridimensionnelles. Il comprend une source lumineuse (10) qui est montée dans la région de la porte de chargement basculante (12, 13, 14, 15), qui doit être contrôlée, de manière à ce que la porte de chargement basculante (12, 13, 14, 15) soit disposée au moins partiellement dans la région éclairée (17) de la source lumineuse (10). De plus, le capteur (9) comprend un groupe de capteurs (11) qui est monté dans la région de la porte de chargement basculante (12, 13, 14, 15), qui doit être contrôlée de manière à recevoir la lumière reflétée.
