As shown in FIG. 1, the field system 10 installed in a specific enforcement section of the illegal intrusion vehicle detection system by tracking a moving vehicle according to the present invention includes a tracking camera 11, a vehicle number recognition camera 12, It consists of a vehicle tracking server 13 , a violation information database 14 , and a network access point 15 .

First, the tracking camera 11 serves to transmit an image of the cut-in intermittent section and the lane next to it to the tracking server 13 . In particular, the tracking camera 11 is installed at a position where image information can be secured by photographing a vehicle traveling between the starting point and the ending point of the interception control section and in the next lane of the intermittent section, and depending on the length of the intermittent section, 1 A large or a plurality of tracking cameras may be installed. As the tracking camera 11, an omnidirectional camera or a dome camera may be employed.

The vehicle number recognition camera 12 is mainly installed in a position that can clearly photograph the front of the vehicle that is out of the end point of the cut-in intermittent section. This is to prepare for the case where the vehicle number of the vehicle driving by cutting in from the next lane of the cut-in enforcement section is not recognized, making the vehicle in violation of the cut-in as a moving object and tracking it before and after leaving the cut-in enforcement section. This is to use as evidence by clearly photographing the license plate number and driver of the breaking-in violation vehicle in a location where there is no interference by the vehicle.

The vehicle tracking server 13 detects the movement of the driving vehicle from the image received from the tracking camera 11, extracts each of the driving vehicles as a moving object, and also extracts and analyzes the license plate from the front of the driving vehicle. After recognizing the vehicle number, as shown in FIG. 2, the recognized vehicle number is connected with the corresponding moving object, and the moving object proceeds until the moving object leaves the image, that is, until it leaves the intervening control section. Executes an operation to trace the path.

As shown in FIG. 3 in the process of performing the operation of tracking the progress path of the moving object in the vehicle tracking server 13, when vehicles are slowing down or standing still in the intervention section, from the next lane to the cut-in section. When a vehicle that cuts in is detected, it is judged as a vehicle that violates the violation, for example, a tag of 'violation' is linked to the vehicle to track the progress path until it leaves the interference enforcement section, and the video at that time is recorded in the violation information database ( 14) is saved.

The vehicle tracking server 13 is equipped with AI tracking software to extract the moving object and the vehicle number from the image of the tracking camera 11 by AI deep learning, thereby increasing the tracking rate of the moving object and the recognition rate of the vehicle number.

In addition, the tracking camera 11 and the license plate recognition camera 12 can transmit an RTSP (Real Time Streaming Protocol) image to receive the captured image from the tracking camera 11 and the license plate recognition camera 12 The vehicle tracking server 13 is configured to recognize and store the vehicle number of the breaking-in violation vehicle, the breaking-in violation time, the violation location, and the tracking image in real time.

In addition to this, the tracking camera 11 is composed of a so-called PTZ camera with a function of rotating the camera, a function of adjusting the vertical angle, and a function of zooming in/out. It is designed to clearly provide the infringing vehicle and the place of violation by photographing the front or the entire exterior of the vehicle or taking a picture with the surrounding environment, including the breaking vehicle.

The vehicle tracking server 13 as described above analyzes the image received from the tracking camera 11 and extracts it as a moving object for the driving vehicles, and extracts and analyzes the license plates of the driving vehicles from the image. After recognizing the vehicle number, the recognized vehicle number is linked with the corresponding moving object and the location is tracked until the moving object is out of the image. creates a new record and stores the vehicle number, the time of breaking in violation, the location of the violation, and the tracking image.

The license plate recognition camera 12 preferably employs a high-definition camera in order to increase the recognition rate of the license plate number, and it is also preferable to employ a camera with an integrated infrared light to enable night photography.

In the above embodiment, the moving object is extracted from the image information photographed by the tracking camera 11 and the vehicle number can also be recognized. An example has been described in which the license plate number of the breaking-in violation vehicle can be photographed again to provide more clear evidence, but the present invention is not limited thereto. Of course, the camera 11 can be implemented as a single tracking camera by employing a high-quality and high-performance camera.

On the other hand, as described above, the vehicle tracking server 13 transmits the information on the breaking-in violation vehicle stored in the violation information database 14 to the remote central control system 20 in real time or periodically through the network to control it. It is made so that the history can be saved and searched.

To this end, the central control system 20 receives and processes violation information from the on-site system 10 installed in the cut-in crackdown section across the country, so the tracking camera 11 and the vehicle of each on-site system 10 By assigning a unique ID to each number recognition camera 12, it is possible to specify the violation position of the breaking-in violation vehicle.
