Sorting and packaging of apples by means of digital image processing
(details) |
In the process of packaging high quality apples the proper placement of the fruit in the tray is critical (i.e. the most appealing side should face towards the customer, all stalks should face into the same direction). Currently this sorting is done manually, at an additional cost of about 36 Euro (500 Schillings) per ton of apples. The automation of this process should result in a significant cost reduction. The first step of the packaging process rotates the apple so that its symmetry axis is vertical with either stalk or bloom facing upwards. This is done mechanically. The next step determines the position of the most appealing side of the apple (i.e. the horizontal angle) and decides whether stalk or bloom is facing upwards (the vertical angle). This is done by digital image processing. The apple is rotated by 360 degrees. A digital camera captures a sequence of images at different orientations and the image processing software measures fruit quality and vertical orientation in real-time. In the last step, a robot brings the apple to its ideal position and puts it into the tray. Partnerlist: Schuster Messtechnik |

Route Tracer
(details) |
During an exhibition time of 5 months the whole internet as seen from one internet node should be visualized. The visitors can interact with the scene in the following ways: free 3D navigation, guided navigation (following the node links) and virtually send email (the user will fly behind an email package following a route from sender node to the recipient node). Since the number of expected nodes exceeds the limit of rendering performance multiresolution analysis must be employed. A spatially immersive display is used to let the visitors experience the wideness of the internet. |
