This new video system is not likely to have that problem. All it seems to be is simply knowing the frame rate, having the math needed to do pattern identification so it can "see" the car and identify it in each frame, and then calculating how much it moves from one frame to the next. If you know the geometry of everything's location you can calculate the speed of the moving object, the car. You'd have to have a very accurate clock to control the frame rate, be able to accurately id the edge-center-some point on the car, etc to make it accurate enough for enforcement because you would only be doing the measuring over a very very short distance, so very small errors in measurement of the inputs would make the output inaccurate. If this was done here in AZ in the summer when the air is so hot it distorts the view of what you see from the heat waves and literally can make things seem to shimmer, that kind of shimmer could completely screw up the measurement. If you could do the measurement 100 times you might be able to average it out, but if you only have a couple frames to do the measuring in it's going to be hard to do. The "shimmer" might introduce a 10% error of it's own. Not likely to be good enough in court.
Like most of these things, I suspect the announcement of this "research" greatly hypes their actual success at accomplishing their goal. -- New service to compete with paypal Get $25 pre-registration bonus by following this link www.greenzap.com-25smackers4u
