[0040] When the ultra-wide-angle image acquisition device 2 transmits the oncoming vehicle information on the passage to the control module in the form of a video stream, the license plate recognition module 31 and the trajectory module in the control module respectively recognize the image information in the video stream, so as to determine the front license plate information, the rear license plate information and the driving trajectory information of the oncoming vehicle, so as to accurately capture abnormal behaviors such as vehicle following caused by vehicles closely following and vehicles reversing into the parking lot.

[0041] Further, the control module further includes an alarm module 33.
