Title:
METHOD FOR DETECTING THE POSITION OF THE INTERFACE BETWEEN TWO MEDIA
Document Type and Number:
WIPO Patent Application WO2003060433
Kind Code:
A3
Abstract:
The invention relates to a method for detecting the position of the interface between two media in a container. According to said method, the container is irradiated by light, and the radiation which passes through the container is captured, converted into a video image and evaluated in order to determine the position of the interface in terms of height. The inventive method is characterised in that all of the image information, especially luminosity, colour and intensity of colour, is drawn on in order to process and evaluate the entire video image, optionally after digitalisation.
