The invention discloses a detecting method for vehicle converse running on an expressway and an automatic alarm device. The automatic alarm device comprises an image collecting module, a vehicle converse running detecting module, an alarm blinking lamp, a data transmitting device, and a computer; and the image collecting module, the alarm blinking lamp and the data transmitting device are connected with the vehicle converse running detecting module, and the computer is connected with the data transmitting device. In order to improve the accuracy of the converse running detection, not only the previous frame is detected, but also M frames in the recent N frames are randomly selected for synthetic judgment, the converse running is judged only if the converse running is existent in X frames or more than X frames, the converse running alarm is sent, and the histogram feature and Fourier spectrum feature of the vehicle are combined to perform the multi-vehicle matching, so the matching accuracy is improved.
