This paper describes the set-up of the image processing system installed at the IPR in Karlsruhe. It will serve for sensor device in the programming by demonstration field. As a first application example, it is used as source for images in the demonstration of a bag packaging task. A detection algorithm that finds positions of infusion bags is presented. It was developed at the Department of Computer Architecture of the University of Malaga, and uses a straight line Hough transform after the application of a Canny filter. Then, the position of the rubber caps of the bags are located by a binarization technique to predicate the orientation of the bag. However, since the computing power is quite limited, the algorithms must have as low complexity as possible.
