The main server 200 has its own data server 210 for storing the image data obtained through the Ministry of Education and the vehicle inquiry network 220, the police correction data server 230 and each field system 100.

The photographing unit 120 is placed on the rotating unit 130 to tilt the photographing lens at a predetermined angle or to track and rotate the position. Of course, the rotating unit 130 is commanded to move and rotate so that the vehicle model and the car number of the violating vehicle can be checked according to the instructions of the image processor 151 and the processor 152.

The local controller 150 drives the image processor 151 and the amplifier 153 operated by the processor 152, and the amplifier 153 is configured to be applied to the audio unit 140 and the audio unit 140. Is composed of a voice output unit 141, such as a speaker, and a microphone 142 that listens to local sounds and sends an amplified signal to the amplifier 153.

A third process (S3) of storing still images at minute intervals when the vehicle enters the vehicle, and

When the set time (5 minutes) elapses, it is determined that the parking stop is in violation and performs a fourth process (S4) of recognizing the license plate from the image including the initial entry image and transmitting the license plate to the server;

The main server recognizes the license plate from the 5-minute elapsed image sent by the enforcement officer (S11),

Querying the vehicle with the recognized license plate (S12); And

Based on the data of the inquiry vehicle, a process of preparing an illegal parking violation notice (S13) is performed. The process of recognizing the license plate (S4) or the process of recognizing the license plate in the image taken by the enforcement officer (S11) includes the step of identifying the vehicle model and license plate in the final image (S11-1); Loading the captured image as a sampling image for a minute when recognition is difficult because another vehicle is covered in front of the license plate (S11-2); The process of repeating the sampling image load until the license plate can be confirmed (S11-3) is sequentially performed. 10 shows that the process (S11) is carried out in the main server, but this shows the process of checking the license plate by receiving the image of the site enforcement personnel, itself in the process (S4) of the field system for automatic crackdown of the present invention. Recognize the license plate to immediately perform the process (S12) of the main server.

The present invention configured as described above is installed in the support rod (for example, telephone pole or high building) for each monitoring area, and this is shown as a field system in FIG. 4 for convenience.

In the field system 100, the laser is emitted through the light emitting unit 111 constituting the laser unit 110, and the emitted laser is reflected by the vehicle and received by the light receiving unit 112. The light received by the light receiver 112 is sent to the distance extractor 113 through the receiver 112-1. The principle of distance extraction is to measure the time from the end of the vehicle (T1) to the detection of the other stage (T2), and measure the speed (whether the movement of the animal (the approach for illegal parking)). This technique was used for speeding. However, the present invention sends a frame image divided through the frame division unit 151-1 in association with the photographing unit 120 to the frame processing unit 151-2 for processing. In this case, the frame processing unit 151-2 also functions to capture the correct image even at night by linking the flash unit 151-3 to operate the flash for the captured image. The laser unit 111 corresponds to a characteristic part of the present invention that not only recognizes whether the vehicle enters a parking area but also detects an edge of the vehicle to obtain a perfect image by complementing the image of the photographing unit to obtain an accurate image. . That is, in the present invention, the image processor 151 extracts the edge portion of the vehicle by adding the image signal through the photographing unit 120 and the light signal through the laser unit 110 (Q1 and Q2). Then, the horizontal and vertical edges of the vehicle are extracted (Q3). Based on the extracted edge, the vehicle recognizes the model and license plate and sends the image to the main server 200 (Q4). Of course, the process of sending to the main server 200 is a general Internet process sent through the Internet network 4 via the wireless transmission device 8 via the LAN card 7 under the control of the processor 152 of the local control unit 150. Since it is carried out through the detailed description thereof will be omitted. Of course, it is also possible to select from other wired and wireless methods that can perform the Internet.

In this case, the recognized vehicle may be checked based on the data of the vehicle which has been corrected as shown in FIG. 8.

In addition, the present invention can be advantageously used for parking stops. By using the laser unit 111 to determine whether the vehicle has entered, there is no need to install a separate loop sensor on the floor to recognize whether the vehicle has been previously entered, so it is possible to easily crack down on any vehicle in violation of the parking lot, By focusing on the edges of the vehicle and analyzing them with existing images, it is possible to drastically reduce the error of crackdown by identifying the correct model with the noise of the vehicle, such as shadows and lights, removed.

To this end, the laser transmits three-dimensional distance data at speeds of up to three meters per second (but not limited to), to accurately determine whether a vehicle is entering or entering an area where parking is prohibited. The meaning of grasping here means driving the laser unit 110 and the photographing unit 120 to recognize and capture an image for control.

The present invention for controlling illegal parking starts using the field system 100 installed in the corresponding area as shown in FIG. 4 to start the parking stop recognition and image recording of the target through the laser unit 110 and the photographing unit 120. This is because it is possible to crack down if it is simple to stop within 1-2 minutes or at least 5 minutes to deliberately stop for 5 minutes.

Therefore, the processor 152 constituting the field system 100 commands the operation of the laser unit 111 and the photographing unit 120 through the image processor 151. Then shooting starts (S1). The start of photographing means that the image processing unit 151 processes the image in accordance with a standardized format and stores the image in the storage medium 154 under the control of the processor 152.

Then, it is determined whether there is a moving object and a vehicle among the captured images (S2). In this case, identifying the moving object is to determine whether the vehicle is moving or a person is moving. Of course, if necessary, such as a thief, such as overhanging the garbage, unauthorized waste, unauthorized pissing, etc. can be determined depending on the setting.

When the determined image is determined to be a vehicle, the processor 152 continues to count the stopping time of the target vehicle while continuing to photograph the parking stop area as before (S31). While counting, the video at the time is divided and stored separately for each minute (set time) (S32). While repeating this, the process (S3) is performed to check whether the set time (for example, 5 minutes) has passed (S33).

After the set time has passed (the processor 152 recognizes it using its own timer), the image is taken over time, the license plate is recognized from the image taken per minute, and there is an obstacle in front of or behind the vehicle, making it difficult to recognize. The license plate can be recognized on the basis of the image of the initial entry. After the recognition, the processor 152 transmits the data and video to the wireless transmission device 8 such as netspot via the LAN card 7, and the wireless transmission device 8 transmits the main server 200 through the Internet network 4. (S4) (of course, you can also use a dedicated line or other Internet communication network).

This process may be taken by the enforcement officer bar, in this case, just transfer the shooting video to the main server (200). Then, the main server 200 distinguishes the license plates based on the images so as to recognize them (the principle of recognizing the license plates is to extract the license plate parts attached to the front and rear sides of the vehicle based on the photographed image, and to grasp the characters based on the images) License plate recognition) To determine the correct vehicle number (S11).

Through the vehicle number identified through the image processing (license plate recognition) of the enforcement personnel or license plate recognition image through the field system, the main server 200 connects the vehicle inquiry network 220 to determine the owner and address of the vehicle ( S12). An illegal parking violation violation notice is prepared based on the identified track (S13). In this case, if the vehicle is an invincible or stolen vehicle, the police department data server 230 is notified of the data.

As described above, the present invention grasps the vehicle through the laser unit and the photographing unit, so that it is possible not only to control the speed, but also to accurately stop the vehicle.

In addition, the present invention is to determine whether the illegal parking vehicle enters the field system, which improves the efficiency of crackdown by enabling the identification of the number of vehicles even when there is an obstacle in front of the vehicle.

In addition, the present invention is to check whether or not a violation of parking stops per minute, so that after a set time (for example, 5 minutes), automatically take a video and check the number from the captured video, so it is fair in the area where the present invention is installed Accurate crackdowns will continue to be available throughout the year, contributing to cracking down on illegal parking on the road, and contributing to securing revenue from illegal parking.

Of course, it can be processed by the main server by receiving the data of the general parking enforcement officers, it is convenient to use the existing enforcement officers with the enforcement data until the on-site system is complete.
