“Extremely accurate” number plate cameras
Wednesday, July 25th, 2007Automatic Number Plate recognition gets 1 in 25 read-outs wrong, the Department for Transport reveals.
We discovered last week - thanks to an inadvertent leak from the Home Office - that the whole national network of ANPR cameras will soon be linked in to the police.
So the accuracy of the cameras is pretty vital.
And while 96% is pretty good as a mark in a maths test, it’s less good when it comes to tracking car drivers’ every movement. When you consider that the cameras monitor millions of cars, 4% failure turns into thousands upon thousands of false positives.
