Vehicle size identification method, device and system in ETC scene and medium

Abstract

The invention discloses a vehicle size identification method, device and system in an ETC scene, and a medium. The method comprises the steps: obtaining the distance R between vehicles and a radar andthe pitch angles theta of the vehicles through the radar installed at a preset height H; obtaining the heights h of the vehicles according to the preset height H, the distance R and the pitch anglestheta; and classifying the sizes of the vehicles according to the heights h of the vehicles. The vehicle size identification method, device and system in the ETC scene and the medium have the advantages of being easy and convenient to operate, low in cost, capable of classifying the sizes of vehicles and avoiding missing fee deduction and the like.

Description

technical field [0001] The present invention relates to the technical field of ETC, in particular to a vehicle size identification method and device in an ETC scene. Background technique [0002] ETC is a non-parking electronic toll collection system. Although it is convenient, there are still some problems. A typical problem is the situation where a small car follows a big car in front. If it is relatively close to the car, it may cause occlusion, resulting in the small car following the big car not being able to successfully deduct the fee. At present, image recognition is routinely used, combined with deep learning methods to classify vehicles. Although the deep learning method has obvious advantages in target classification, the operation is complex, costly and time-consuming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle size recognition method, device, system and medium in an ETC scene with ea...
