IN THE PIPELINE
1The sewer systems of Europe could soon provide a conduit for more than water and waste. A machine vision 4sewer inspection project has sparked 5interest in using the pipes to lay cables 6for telecommunications traffic. The project, named Inspecting Sewage Systems and Image Analysis by Computer, or Isaac, is part of a larger 10European Commission-backed initiative to promote use of vision technology.
Project coordinator Mark Sawyer explained that the inspection system employs a tractor-mounted CCD matrix 15camera and curved mirrors for imaging inside the pipes, and proprietary software to convert the data into a perspective that humans can interpret. It 19will enable rapid detection of defects in 20pipe walls and could be in operation within 18 months.
“The prospect of using the sewers 23for telecommunications is still evolving”, 24he said. Commercial relationships 25between cable companies and sewer landlords must be negotiated, and the technology to install cables has yet to be developed. “However,” he added, “an accurate survey of the sewer system 30brings it closer.” It’s a concept that could 31well “go down the tubes”.
