Scientists Invent Undetectable Speed Detector
http://www.thenewspaper.com/news/03/343.asp
Scientists Invent Undetectable Speed Detector Military technology is used to create a visually based speed measurement device. University of Florida researchers believe they have outwitted the makers of radar detectors and other speed detection countermeasures. Using a $5 million grant from the Air Force, they've developed software that can use live video camera footage to recognize objects and measure their speed. It does so by calculating the distance a car moves in a series of photos compared to a fixed object -- such as a light pole -- in the background. Because the system is entirely passive, unlike conventional laser and radar speed guns, it cannot be detected. "If it can view the object moving, that's all it needs. The computer figures out everything else," said Warren Dixon, University of Florida assistant professor of mechanical and aerospace engineering. "We're trying to use both regular and infrared cameras, so night or adverse weather conditions don't present a problem." The system is similar to the SPECS speed averaging cameras in use in the UK and Australia. The latter system uses multiple cameras to calculate a car's speed over a known, fixed distance. The researchers believe they can create a device has two big advantages over SPECS -- it would be entirely mobile and it would work with a single camera. The military continues to be interested in potential applications for the software. Additional details on their research will be published in the latest issue of IEEE's Transactions on Robotics and Automation. |

Undetectable camera enforcement systems have existed for over a century. The question is not can the government monitor every driver's speed, the question is will the people let the government monitor every driver's speed. -- John Carr ) |

It is electronic, it has some sort of signature that can be detected. Not economical to detect at the present time is more accurate. > "If it can view the object moving, that's all it needs.

If there is no greater evidence that the speeding ticket industry is profitable, it's the existance of this project. Seriously, if it was about safety, it wouldn't take any special gizmos to convict people. Just a dash camera on the cop's car showing the ticketed driver driving unsafely. We only need the gizmos because the violation isn't about safety, it's about going faster than an arbitary number on a sign. |

This isn't new. Cops here have been using helicopters with observers that
measure time a vehicle passes between two painted lines of known distance to measure speed for decades.

At the risk of sounding like judy, that's why I favor jailing speeders. Make it start costing these towns money instead of making them money and watch the speed traps dry up. |

It is a good idea. |
