Abstract
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur zeitaufgelösten (möglichst echzeitfähigen) Analyse von Transferfilmen beim Kontakt zweier unterschiedlicher Oberflächen. Um ein Verfahren zu schaffen, das eine vollflächige Abbildung des jeweiligen Transferfilms ermöglicht, und das weitestgehend automatisierbar ist, wird im Rahmen der Erfindung vorgeschlagen, dass • eine photographische Kamera so platziert wird, dass sie auf den Ort des Kontaktes zwischen zwei Oberflächen, die sogenannte Laufspur, gerichtet ist, • während des Betriebs in der gewünschten zeitlichen Auflösung mit der Kamera Bilder aufgenommen werden, • für jedes aufgenommene Bild ein Weißabgleich zur rechnerischen Normalisierung von Farbe und Helligkeit erfolgt und das Bild entsprechend korrigiert wird, • für jedes aufgenommene Bild der Grauwert im Bereich der Laufspur sowie in einem Referenzbereich außerhalb der Laufspur bestimmt wird, • der anhand der Grauwerte der Aufbau bzw. Abbau des Transferfilms über die Zeit in einer Auswerteeinheit ermittelt wird.
(EN) The invention relates to a method and a device for a time-resolved analysis (optimally with real-time capability) of transfer films during the contacting of two different surfaces. To provide a method that allows the imaging of the entire surface of the relevant transfer film and that can be automated to the greatest extent, according to the invention: • a photographic camera is placed such that it is directed onto the site of contact (contact area) between two surfaces • during operation images are captured with the camera with the desired time resolution • a white balance is carried out for each image in order to arithmetically standardize the colour and luminance, and the image is corrected accordingly, • for each image captured, the grey-scale value is determined in the region of the contact area and in a reference region outside the contact area, • the build-up and breakdown of the transfer film is determined over time in an evaluation unit, on the basis of the grey-scale values.
(FR) L'invention concerne un procédé et un dispositif d'analyse à résolution temporelle de films de transfert lors du contact entre deux surfaces différentes. L'invention vise à proposer une analyse qualitative et/ou quantitative à résolution temporelle (de préférence appropriée au temps réel) de films de transfert qui permette une représentation de la totalité de la surface du film de transfert concerné, qui s'accompagne d'une demande réduite en investissement et entretien, et qui puisse être en grande partie automatisée. À cet effet, • un appareil photo est placé de telle manière qu'il est orienté sur l'emplacement de contact entre deux surfaces, ladite voie de roulement, • des images sont prises par l'appareil pendant le fonctionnement à la résolution temporelle souhaitée, • un équilibrage des blancs est effectué pour chaque image prise pour la normalisation numérique de la couleur et de la luminosité, et l'image est corrigée en conséquence, • la valeur de gris dans la zone de la voie de roulement ainsi que dans une zone de référence hors de la voie de roulement est déterminée pour chaque image prise, • l'élaboration ou la décomposition du film de transfert dans le temps est déterminée dans une unité d'évaluation. L'invention propose pour la première fois une analyse de la valeur de gris ou de la luminosité qui permet de détecter le film de transfert non seulement sur certaines parties mais sur toute la surface, et qui présente une résolution temporelle (jusqu'à une aptitude à l'utilisation en temps réel) sans que l'essai ou le fonctionnement soit perturbé par l'intermittence. Le procédé peut ainsi être également utilisé en association avec un essai ou un fonctionnement.
