Definitions

  • a number of objects are provided with said marking means, where the objects 20 are monitored for uncontrolled displacement.
  • False markers can eventually appear if there are many bright objects in an image, which 10 the camera apprehends as a reflex mark. False markers can be filtrated in most of the cases by means of that the measuring system contains information concerning the shape of each mark. The false markers, which eventually remain after the filtration, are no problem since they are in fact stationary. Varying strong sunlight may cause problem through dazzling the system, but by means of appropriate camera location, such problems can be eliminated. 15

Abstract

L'invention concerne un système de surveillance (10, 20) permettant de surveiller au moins un objet fixe, mais déplaçable, à l'intérieur d'un volume, cette objet comprenant au moins un élément de marquage (13, 13a-13d, 23) sous la forme d'un dispositif de génération de lumière ou de réflexion. Ce système comprend au moins une unité d'enregistrement optique (11, 21) permettant d'enregistrer une image d'au moins une partie du volume contenant ledit objet pourvu d'au moins un élément de marquage (13, 13a-13d, 23), un dispositif de transformation de l'image en une représentation numérique de cette même image, un élément (14) de comparaison de la représentation numérique avec un ensemble de données stockées, et un dispositif de génération d'un signal en présence d'un écart lors de la comparaison entre la représentation numérique et l'ensemble de données stockées. L'ensemble de données stocké comprend au moins une valeur de coordonnée stationnaire bidimensionnelle destinée au positionnement initial de l'élément de marquage (13, 13a-13d, 23), le système possédant un élément d'extraction d'au moins une valeur de coordonnée stationnaire, laquelle est une valeur de coordonnée bidimensionnelle, de la représentation numérique destinée à l'élément de marquage, l'élément de comparaison (14) comparant cette valeur de coordonnée bidimensionnelle extraite à la valeur de coordonnée stationnaire stockée.
