The invention provides a method and a device for monitoring the abnormal behavior of a motor vehicle on an expressway. The method comprises the following steps of dividing and setting a monitoring area; decoding two paths of split-screen video image streams of a holographic high-definition video cameras into a single-frame image; performing deblurring and background refreshing processing on the image; detecting the motor vehicle, and tracking the motor vehicle; analyzing the driving behavior of the motor vehicle in the image; rotating a high-definition dome camera to the position of the motor vehicle to capture an image; identifying the license plate number of the motor vehicle in the image, combining the identified license plate number of the motor vehicle and the abnormal behavior of the motor vehicle into a warning statement for field playing, and simultaneously giving an alarm. According to the method and the device, the abnormal behavior of the motor vehicle on various rapid expressways is automatically identified for accurate detection and capturing of images, data and the like, and the warning statement is wirelessly transmitted and broadcast through a loudspeaker on the spot to timely prompt a driver to normally drive the motor vehicle, so that the occurrence of a fatal traffic accident can be effectively avoided, and the life and property safety of people is protected.
