The invention relates to the technical field of intelligent traffic, in particular to a tunnel overtemperature vehicle identification method and system, and the method comprises the steps: collecting tunnel vehicle photos to generate a tunnel vehicle photo data set, dividing the tunnel vehicle photo data set into a training set and a verification set according to the proportion of 7: 3, and generating corresponding label files; establishing a vehicle identification model; training a vehicle identification model based on the collected tunnel vehicle photo data set, and calculating a loss function until the loss function value converges to a preset value to obtain a trained vehicle identification model; according to the method, the vehicle related information, namely the vehicle license plate data and the vehicle type, can be identified by adopting the deep learning algorithm according to the vehicle picture information captured by the checkpoint capture camera, and the overtemperature vehicle is early warned and reported, so that the early warning efficiency is improved. And support is provided for safe operation of the tunnel.

    本发明涉及智能交通技术领域,具体涉及隧道超温车辆识别方法及系统,包括步骤:采集隧道车辆照片以生成隧道车辆照片数据集,隧道车辆照片数据集按照7:3的比例分为训练集和验证集,并生成对应的标签文件;建立车辆识别模型;基于采集到的隧道车辆照片数据集对车辆识别模型进行训练,并计算损失函数,直至损失函数值收敛至预设值,以得到训练好的车辆识别模型;利用训练好的车辆识别模型对待识别的隧道车辆照片进行识别,以得到识别结果,本发明方法能够根据卡口抓拍相机抓拍的车辆图片信息,采用深度学习算法识别车辆相关信息,即车辆车牌数据、车辆类型,并将超温的车辆进行预警上报,为隧道的安全运营提供支持。
