Multilane free-flow electronic toll collection method based on accurate position match

A multilane free-flow electronic toll collection method based on accurate position match is characterized in that electronic tag positioning and vehicle position detected results are matched to achieve multilane free-flow electronic toll collection. The method comprises the following steps: 1, obtaining vehicle-mounted electronic tag positions, vehicle positions and vehicle images to perform electronic on-stream toll collection; 2, accurately matching the vehicle-mounted electronic tag positions and the vehicle positions to distinguish legal vehicles and illegal vehicles; and 3, performing background data processing, storing images, license numbers and illegal passing records of the illegal vehicles to be used as the basis of toll collection. By accurately matching the vehicle detected results and electronic tag positioning results, the judgment of the legal vehicles and the illegal vehicles is achieved, and accordingly the multilane free-flow electronic toll collection is achieved.
