| 摘要 |
The invention concerns a method for detecting foam on a liquid surface (14) in a vessel (10), comprising the steps:
- a) providing a vessel (10), particularly a tube-shaped vessel, which has an upper opening (12) surrounded by a border and which includes an amount of a liquid,
- b) taking at least one image of the liquid surface (14) from the top of the vessel (10) through the opening (12) of the vessel (10) by using an image sensing device (20) providing corresponding image data,
- c) performing an automatic evaluation of said image on the basis of said image data by means of a data processing system (30) using an image evaluation program that is adapted to identify foam specific areas in the image and to provide information about the presence or absence of foam specific areas in the image as a result of the image evaluation. Subject of the invention is also an apparatus for performing the method. |
