PROSPECT is an ENTICE TTN (European Technology Transfer Node Activities) result concerning an automatic inspection system for carpets. Using digital signal processing (DSP) and vision systems, combined with High Performance Computing and Network (HPCN) techniques, the carpet can be inspected automatically for faults on the production line. Inspecting visually several thousands of meters of carpet a day is tiring and prone to human error. The key to the system is the use of powerful but inexpensive computing technology to analyze the image of the carpet. The system must be able to process the images quickly in order to keep up with the speed of the carpet as it comes off the production line. Linking together several similar components achieves this. The test system can easily be expanded by the addition of more processors, to bring more algorithms to bear and to handle the full set of user requirements.
A study was undertaken, which showed how, by the use of HPCN techniques, it would be possible to extend the test system to cover the whole width of any carpet moving at higher speeds, and to detect all the types of faults required. If the PROSPECT product is developed to detect all faults, the system could be sold for a minimum of 300 000 Euros per system. This would easily be recovered as productivity could be raised by 20-30%.
