By comparing the measured size of the monitored object with a modeled, perspective size of the monitored object at the same object position, one of the visual obstacles is concluded.
- the image processing method is based on the fact that the monitoring object is assigned to a class, for example persons, of whom a middle one belongs or usual size is known and based on this size, the modeled, perspective size is determined.

- each point of the monitored area, ie the surveillance scene is assigned a real, three-dimensional object point in the surveillance area.
- the advantage of the image processing device can be seen in the high significance, since after a positive recognition of a partial area of the monitored object and a non-recognition of further partial areas of the monitored object, the last-mentioned partial areas must be covered.
- the depth map there is an advantage in that the
- Depth card can also be calibrated in monitoring areas where almost no floor surface of the monitoring area can be seen.

Abstract
Dans le but de décharger le personnel de surveillance et d'améliorer la qualité de la surveillance, des procédés de traitement d'image qui évaluent les données vidéo enregistrées par l'intermédiaire d'un traitement d'image numérique ont été proposés. Dans les procédés habituels, des objets de surveillance en mouvement sont séparés de l'arrière plan essentiellement statique, suivis au cours du temps et une alarme est déclenchée en cas de mouvements pertinents. Toutefois, les données vidéo ne montrent d'abord qu'une représentation en deux dimensions des zones de surveillance. Une poursuite de l'objet de surveillance au cours du temps - également appelée trajectoire - ne fournit donc, sans autre évaluation, aucune conclusion sur le déplacement effectif de l'objet de surveillance dans la zone de surveillance. L'invention concerne un dispositif de traitement d'image 13 pour un système de surveillance vidéo permettant de surveiller une zone de surveillance 1, qui peut présenter au moins un objet de surveillance 2 et a moins une géométrie de couverture 3, avec un module de détection 15 qui est conçu pour détecter un objet de surveillance 2, la détection de l'objet de surveillance 2 ayant lieu sur la base d'une quantité de détecteurs de zone partielle 7 a - e qui détectent les différentes zones partielles de l'objet de surveillance 2 et, la quantité de détecteurs de zone partielle 7 a - e étant subdivisée, lors de la détection de l'objet de surveillance 2, en une quantité positive 8 de détecteurs de zone partielle qui ont reconnu la zone partielle associée de l'objet de surveillance 2 et en une quantité négative 9 de détecteurs de zone partielle qui n'ont pas reconnu la zone partielle associée de l'objet de surveillance 2. Le dispositif de traitement d'image comprend également un module d'étalonnage 16, 17 qui est conçu pour étalonner, sur la base d'un objet de surveillance détecté 2 avec une quantité négative 8, une carte de profondeur et/ou une géométrie de couverture pour la zone de surveillance 1.
