Vehicle type classification within traffic flow - comparing vehicle silhouette with patterns stored in memory

摘要

The method determines the distance between the passing vehicle and the detectors and the height of each vehicle is calculated. A number of successive measurements are performed for each passing vehicle. The silhouette of a vehicle found from a number of measurements is compared with patterns of silhouettes stored in a memory so that the type of the vehicle can be determined. USE/ADVANTAGE - Improved classification of types of vehicle passing measuring point, even with several lanes of traffic.
