SYSTEM FOR DETECTING OVER AXLE WEIGHT VEHICLE
First Claim
1. An over axle weight vehicle detecting system comprising:
- an axle weight detecting section configured to detect a weight of an axle of a vehicle at a first position on a lane;
a sensor configured to detect a vehicle at a second position set within 8 meters downstream side of the first position to generate a detection signal;
a camera unit configured to take an image of a vehicle in response to the detection signal; and
an over axle weight vehicle candidate extracting section configured to choose a vehicle detected by the sensor at first and a vehicle detected by the sensor at second as candidates of an over axle weight vehicle violating an axle weight regulation when the axle weight exceeds a predetermined value.

Abstract
A technique for recording the front image of vehicles which violate the regulation in the axle weight is desired. In general, the weight of the leading axle cannot be excessively heavy, so that the over weight axle is a second or more rear side axle. And the distance between an axle weight detector and a vehicle detector for taking a vehicle image is normally below 8 meters. Under these conditions, when the over weight axle is detected, the over axle weight vehicle is guessed to be a vehicle being presently detected, a vehicle to be detected next, or next to the next. From the images of those vehicles, vehicles having no possibility to violate the axle weight regulation are eliminated based on a license plate read from the vehicle image or the measured vehicle height. The images being not eliminated are stored as over axle weight vehicle images.
