The embodiment of the invention relates to the technical field of high-speed detection, and discloses an abnormal vehicle detection method based on a highway, and the method comprises the steps: carrying out the image recognition of vehicle image information, so as to determine the corresponding vehicle type information; performing laser scanning on the corresponding vehicle through a laser identification device to obtain vehicle size information; if yes, an infrared thermal imaging module for starting the second recognition area is controlled to be started, and a thermal imaging image of the corresponding vehicle is obtained through the infrared thermal imaging module; vehicle motion information belonging to the second vehicle type information in the third identification area is acquired, and vehicle motion features are constructed through the vehicle motion information; and inputting the vehicle motion features into an abnormal vehicle identification model for detection to determine whether the vehicle associated with the vehicle motion features is an abnormal vehicle. According to the abnormal vehicle detection method based on the expressway provided by the embodiment of the invention, fine detection of toll evasion vehicles under various different conditions is realized by arranging multiple stages of detection areas in front of the entrance gate.

    本发明实施例涉及高速检测技术领域,公开了一种基于高速公路的异常车辆检测方法,包括:对车辆图像信息进行图像识别以确定相应的车型信息;通过激光识别装置来对相应的车辆进行激光扫描以得到车辆尺寸信息;则控制启动第二识别区域的红外热成像模块启动并通过红外热成像模块来获取相应车辆的热成像图像;获取处于第三识别区域中属于第二车型信息的车辆运动信息,通过车辆运动信息来构建车辆运动特征;将车辆运动特征输入到异常车辆识别模型中来进行检测以确定与车辆运动特征关联的车辆是否为异常车辆。本发明实施例中的基于高速公路的异常车辆检测方法通过在入闸口前设置多级检测区域来实现对多种不同情况的逃费车辆的精细化检测。
