The invention relates to a device for monitoring a lift area by means of a 3D semiconductor sensor (79) for acquiring three-dimensional image information. Said semiconductor sensor (79) comprises a light source which is mounted in such a way that the lift area to be monitored is located in the region illuminated by the light source, a sensor group which is mounted in such a way that it receives reflected light, and a processing chip for converting the electrical signals into image information. Said device is also provided with a processing unit (80) which is connected to the semiconductor sensor (79) in order to supply three-dimensional image information. Said processing unit (80) processes the image information in order to obtain state information which represents the state of the lift area to be monitored.
L'invention concerne un dispositif pour surveiller une zone d'un ascenseur au moyen d'un capteur 3-D à semi-conducteurs (79) qui sert à acquérir des informations d'images tridimensionnelles. Ledit capteur à semi-conducteurs (79) présente: une source lumineuse, montée de manière à ce que la zone d'ascenseur à surveiller se trouve dans la zone éclairée par la source lumineuse; un groupe capteur, monté de sorte qu'il reçoit la lumière réfléchie; et une puce de traitement servant à convertir les signaux électriques en informations d'images. Le dispositif selon l'invention présente en outre une unité de traitement (80) qui est raccordée au capteur à semi-conducteurs (79) pour mettre à disposition les informations d'images tridimensionnelles. Cette unité de traitement (80) traite les informations d'images pour permettre l'acquisition d'informations d'état qui représentent l'état de la zone d'ascenseur à surveiller.
