Title
(DE) FÜLLVOLUMEN-MESSUNG
(EN) FILL VOLUME MEASUREMENT
(FR) MESURE DE VOLUME DE REMPLISSAGE
Abstract
(DE) Die Erfindung betrifft ein Mess-System zur Bestimmung eines Füllvolumens eines Füllgutes (4) in einem Behälter (3). Hierzu umfasst das Mess-System eine 3D-Kamera (2) und ein Radar-basiertes Füllstandsmessgerät (1). Die 3D- Kamera (2) dient dazu, um zunächst zumindest ein 3D-Bild ([pi,j]) von zumindest einem Teilbereich des leeren Behälter-Inneren aufzunehmen. Anhand der 3D-Bilder ([pi,j]) wird einen Datensatz bzw. ein digitales Raum- Model erstellt, mittels welchem zumindest diesem Teilbereich die Geometrie des leeren Behälter-Inneren repräsentiert wird. Zur Erstellung des erforderlichen, dreidimensionalen Oberflächen- bzw. Füllstands-Profils (L(a, ꞵ)) basiert das Füllstandsmessgerät (1) auf einem digitalen Strahlformungsprinzip, wie beispielsweise dem MIMO-Prinzip. Somit kann anhand des Datensatzes, der die Geometrie im Behälter-Inneren wiederspiegelt und anhand des Füllstands-Profils (L(a, ꞵ)) das Füllvolumen im Behälter (3) bestimmt werden.
(EN) The invention relates to a measuring system for determining a fill volume of a filling material (4) in a container (3). For this purpose, the measuring system comprises a 3D camera (2) and a radar-based fill-level measuring device (1). The 3D camera (2) is used to first capture at least one 3D image ([pi,j]) of at least one portion of the empty container interior. On the basis of the 3D images ([pi,j]), a data set or a digital spatial model is created which represents the geometry of at least this portion of the empty container interior. In order to create the required three-dimensional surface or fill-level profile (L(a, ꞵ)), the fill-level measuring device (1) is based on a digital beam forming principle, such as the MIMO principle. Therefore, the fill volume in the container (3) can be determined on the basis of the data set reflecting the geometry in the container interior, and on the basis of the fill-level profile (L(a, ꞵ)).
(FR) L'invention se rapporte à un système de mesure permettant de déterminer un volume de remplissage d'un matériau de remplissage (4) dans un récipient (3). À cet effet, le système de mesure comprend une caméra 3D (2) et un dispositif de mesure de niveau de remplissage radar (1). La caméra 3D (2) est utilisée pour capturer d'abord au moins une image 3D ([pi,j]) d'au moins une partie de l'intérieur du récipient vide. En fonction des images 3D ([pi,j]), un ensemble de données ou un modèle spatial numérique, qui représente la géométrie d'au moins cette partie de l'intérieur du récipient vide, est créé. Afin de créer le profil tridimensionnel requis de surface ou de niveau de remplissage (L(a, ꞵ)), le dispositif de mesure de niveau de remplissage (1) est fondé sur un principe de formation de faisceau numérique, tel que le principe MIMO. Ainsi, le volume de remplissage dans le récipient (3) peut être déterminé en fonction de l'ensemble de données reflétant la géométrie dans l'intérieur du récipient, et en fonction du profil de niveau de remplissage (L(a, ꞵ)).
