Description

TECHNICAL FIELD [0001] The present invention relates to a system for detecting an intersection traffic violation vehicle,

The present invention relates to an intersection traffic violation vehicle control system, and more particularly, to an intersection traffic violation vehicle control system for ignoring a signal at an intersection and entering an intersection, The present invention relates to a method of controlling a traffic violation vehicle.

As society develops, urbanization and living standards improve, the number of cars is rapidly increasing every year. As a result, severe traffic congestion is occurring in cities as well as small and medium-sized cities, and economic losses are increasing every year.

In order to improve the traffic congestion, a variety of methods have been attempted through the establishment of roads and improvement of the traffic signal system. However, since it is not feasible to open a new road in the city, proper control of traffic flow This is recognized as an important method every week.

Meanwhile, the above-described traffic signal system provides an effect that the traffic flow can be smoothly performed when the driver operates the vehicle while observing the traffic signal properly.

However, when we look at our traffic situation, we can often witness traffic signals are ignored if the traffic flow stagnates. Particularly, in the case of vehicles passing through an intersection, it is difficult to enter the intersection without knowing clearly that even if the straight ahead and left turn signals are received normally and the vehicle enters the intersection, the vehicle can not get out of the intersection during the signal period. However, I can often see so-called tail-waders, who are already pushing back in front of cars and pushing into the intersection, even though the signal has changed, but the cars in the other direction are moving in the same direction There is a problem in that it can not be performed.

In this way, by entering the intersection with the tail at the intersection, the average delay time is lengthened, the driving speed is decreased, the fuel cost is increased to weaken the competitiveness of the country, and if the intentionally entering the tail at the intersection, , It is possible to install a warning sign such as "prohibition of entry at the crossroads" in the congested intersection so that the driver confirms it and does not enter the intersection when the congestion is congested .

Also, more aggressively, traffic police officers are concentrated in the traffic congestion time to control the intersection tail wagons. However, in this case, it is not easy for the police officers to control and control the numerous intersections, There is a problem in that it is inefficient and difficult to actively interfere.

Therefore, it is urgent to develop a system that can control traffic violation vehicles that enter traffic through intersection by ignoring traffic signals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

1 and 2, an intersection traffic violation vehicle enforcement system 100 according to a first embodiment of the present invention includes an entrance vehicle detection sensor 110, an entrance vehicle photographing apparatus 120, An intermittent vehicle identification number camera 140, a control unit 150, and a storage unit 160. The control unit 150 includes a control unit 150,

Here, in the first embodiment of the present invention, the intersection is a four-way intersection 10, for example. The intersection 10 is provided with a pedestrian crosswalk 11 each of which can be divided by the pedestrian crosswalk 11 into a rectangular intercepting area 12 of the intersection 10. A stop line (13) is provided adjacent to the crosswalk (11).

In the vicinity of the intersection 10, an intersection vehicle signal lamp 183 for controlling the traffic flow of the vehicles is provided, and the operation of the intersection vehicle signal lamp 183 is controlled by the signal controller 181.

The incoming vehicle detection sensor 110 includes a plurality of first to fourth geomagnetic sensors 111, 112, 113, 114 installed adjacent to a stop line 13 of the road and embedded in the bottom of the road. The geomagnetic sensors 111, 112, 113 and 114 are provided for individually detecting the entry of vehicles, which are driven for each lane of the road, into the intersection 10, and are preferably installed between the stop line 13 and the pedestrian crosswalk 11 . When the pedestrian crossing pedestrian 11 is not present in the intersection 10 (for example, when a pedestrian or the like is installed), the pedestrian crossing is installed between the stopping line 13 and the intermittent area 12 in the intersection 10. The plurality of geomagnetic sensors 111, 112, 113, and 114 detect the entry of the vehicle through the change of the magnetic force by the vehicle made of metal when the vehicle comes in. In this way, the geomagnetic sensors 111, 112, 113, and 114 detect the entry of the vehicle, and the sensed information is transmitted to the controller 150. Here, each of the geomagnetic sensors 111, 112, 113, and 114 has its own installed location information. Accordingly, when detecting the vehicle, the geomagnetic sensors 111, 112, 113 and 114 transmit the location information (identification information) to the controller 150 together with the vehicle detection information. Therefore, in the case of, for example, a four-way intersection, the control unit 150 accurately recognizes which lane the vehicle has entered into the intermittent area 12 of the intersection 10, (120).

The entrance vehicle photographing apparatus 120 includes first and second entry vehicle number recognition cameras 121 and 123 for photographing a vehicle entering the intermittent area 12 in the intersection 10 in the direction opposite to each other, And first and second pan tilting drivers 122 and 124 for pan tilting driving the first and second entering vehicle number recognition cameras 121 and 123, respectively.

When the geomagnetic sensors 111, 112, 113 and 114 detect the entrance of the vehicle, the first and second entry vehicle number recognition cameras 121 and 123 take a detection area on the basis of the sensed signal, .

The first and second entering vehicle number recognition cameras 121 and 123 are driven by the first and second fan tilting driving units 122 and 124 in a pan tilting mode so that when changing the display signal of the intersection vehicle signal lamp 183 The first and second entry vehicle number recognition cameras 121 and 123 are controlled by the first and second entry vehicle number recognition cameras 121 and 123 so that the vehicles entering from the validated present lane can be photographed by the first and second entry vehicle number recognition cameras 121 and 123, do. For this, the first and second fan tilting drivers 122 and 124 are controlled by the controller 150 and are driven and controlled in conjunction with the control signal of the traffic signal 181.

The optical area photographing apparatus 130 photographs the entire intermittent area 12 of the intersection 10 in the intermittent area 12, that is, the substantially quadrangular intermittent area 12 defined by the respective pedestrian crosswalk 11 in the case of a four- . In the optical area photographing apparatus 130, all the vehicles entering the intermittent area 12 in the intersection in opposite directions are photographed so as to be contained in one image frame. Accordingly, a plurality of entry vehicles photographed by each of the first and second entry vehicle number recognition cameras 121 and 123 can be tracked and monitored independently within one frame. For this, the control unit 150 assigns an identification number (ID) to each entry vehicle photographed by the entrance vehicle photographing apparatus 120 upon entering the intersection 10, It is possible to continuously track the vehicle-specific movement until it passes over the intersection 10 and passes through the device 130. [

As described above, the optical area photographing device 130 photographs the entire area of the intersection 10 and distinguishes the entry vehicles by objects and tracks the movement. Thus, it can be confirmed that the vehicle passes straight ahead, leftward, or rightward.

The intermittent confirmation number recognition camera 140 is a device for acquiring the vehicle number by interrupting the vehicle staying in the intermittent area 12 in the intersection 10 in a state where the traffic signal for passing the intersection is changed, will be. It is preferable that the intermittent confirmation number recognition camera 140 is a so-called speed dome camera installed so as to locate and photograph a traffic violating vehicle located in the intermittent area 12. [ Therefore, the speed dome camera receives the position information of the entering vehicles located in the intermittent zone 12 in the non-valid state of the intersection 10 through the optical zone photographing apparatus 130, and based on the received position information, Obtain the vehicle number by shooting the traffic violation vehicle that is staying.

The traffic-infringing vehicle photographing image and the car number information captured and obtained by the intermittent confirmation number recognition camera 140 are transmitted to the controller 150.

The control unit 150 stores the traffic-infringing vehicle photographing image and the vehicle number acquired and transmitted by the intermittent confirmation number recognition camera 140 in the storage unit 160. More preferably, The vehicle determined as the offending vehicle matches the photographed image information photographed when the vehicle enters the intermittent area 12 of the intersection 10 and stores it together in the storage unit 160. [

In addition, the optical area photographing apparatus 130 can photograph the intersection vehicle signal lamp 183 of the intersection 10 together so that it can be used as evidence data at a later time. That is, the vehicle number of the illegal traffic vehicle is photographed and recognized in the intermittent confirmation number recognition camera 140, and at the same time, the traffic illegal vehicle and the intersection traffic light 183 appear in the image frame together By photographing, it becomes possible to obtain evidence for interception and processing of the vehicle having the traffic violation. These pieces of evidence data are separately stored in the storage unit 160 and managed.

The control unit 150 receives the traffic control signal from the traffic signal 181 of the intersection 10 and drives and controls the first and second pan tilt driving units 122 and 124 in conjunction with the traffic control signal , And controls the first and second entry vehicle number recognition cameras 121 and 123 to take a position (posture) capable of photographing the vehicles in the lane corresponding to the effective presentation time.

When the entrance of the vehicle is sensed by the geomagnetic sensors 111, 112, 113 and 114, the control unit 150 independently controls the first and second incoming vehicle number recognition cameras 121 and 123 to photograph the area where the detection signal is generated , The vehicle number of the vehicle entering the intermittent area 12 of the intersection 10 can be recognized.

The control unit 150 stores the information obtained in response to a predetermined control signal, that is, the traffic violation vehicle interception information, in the storage unit 260, on the request of the remote server 20, To the remote server (20). Therefore, the remote server 20 can receive the interception information for the traffic violation interrupting vehicle in each of the intersections at various places, and collectively process the information.

It is also possible to transmit the control signal to the control unit 150 from the remote server 20 to the transmission / reception unit 170, for example, the photographing direction and the photographing operation signal for the first and second entering vehicle number recognition cameras 121 and 123 have. Therefore, the remote server 20 can request and obtain the required intersection information.

The method of controlling the vehicle using the intersection traffic violation vehicle enforcement system according to the first embodiment of the present invention having the above-described configuration will be described in detail below.

Referring to FIGS. 1, 2 and 3, the incoming vehicle detection sensor 110 detects a vehicle entering the intersection 10 (S10).

If the vehicle is detected in step S10, the controller 150 determines whether the time when the vehicle is detected is a day or a night (S11).

If it is determined in the step S11 that it is night, the control unit 150 controls the illumination device 190 to be driven in conjunction with the photographing operation of the entrance vehicle photographing apparatus 120 so that the lighting operation is performed (S12) .

Then, the control unit 150 selectively drives the first or second entry vehicle number recognition cameras 121 and 123 so as to photograph the area where the vehicle is sensed and photographs the vehicle, thereby capturing the entry vehicle (S13).

The control unit 150 checks whether the vehicle number of the vehicle is recognized from the photographed image (S14). If not, the control unit 150 generates a time code for each vehicle based on the shooting time (S15).

If the vehicle number is recognized in step S14, the control unit 150 assigns a unique identification number (ID) to each vehicle and matches the vehicle ID for each vehicle (S16).

The control unit 150 controls the optical range photographing apparatus 130 to photograph the entire intermittent area 12 of the intersection 10 in one image frame, ) In accordance with the identified identification number (time code) (S17).

As described above, the intersection entry vehicle is photographed, the vehicle number is recognized, and the process of continuously tracking the movement in the intermittent area 12 for each entered vehicle is performed.

Meanwhile, during the above-described operation, the controller 150 determines whether the state of the intersection vehicle signal lamp 183 is valid or not (S18). If the state of the intersection vehicle signal lamp 183 is not valid, (S19). That is, in the step S19, the control unit 150 determines that the vehicles staying in or entering the intermittent control area 12 of the intersection are the traffic violation vehicles, that is, the tail water vehicles, And obtains the vehicle number of the offending vehicle by photographing the offending vehicle by using the inter-vehicle identification number recognition camera 140. [ The positional value of the offending vehicle is determined by taking the tracking position value tracked in the photographing frame of the optical range photographing apparatus 130 and confirming it, It is possible to secure the vehicle number of the offending vehicle after controlling and adjusting itself.

That is, the image frame for the entire area photographed by the optical region photographing apparatus 130 and the photographed image data photographed by the entrance vehicle photographing apparatus 120 are also matched and acquired and stored in the storage unit 160 (S20) .

On the other hand, if it is determined in step S18 that the state of the vehicle signal lamp is in the effective display state, the control unit 150 extinguishes all the acquired data (S21).

If it is determined that the display signal of the vehicle signal lamp 183 has been shifted to the other side (S22), the controller 150 switches the display signal to the transition signal position shifted in the photographing direction of the incoming vehicle photographing apparatus 120 (S23). In other words, the control unit 150 drives and controls the first and second fan tilting drivers 122 and 124 to switch the shooting direction of the first and second entry vehicle number recognition cameras 121 and 123, So that the user can take a picture of the entering vehicle.

Then, the side where the traffic signal is switched continuously detects the incoming vehicles, recognizes the numbers, tracks them, and interrupts the traffic violating vehicle.

As described above, as described above, the entrance vehicles in the intersection 10 are photographed to recognize the number, the position of the recognized vehicles is tracked by object, and the traffic violation vehicle, that is, It is possible to precisely control the tail water vehicle. In other words, the position of the tail water vehicle can be precisely detected by comparing the effective display state of the vehicle from the entry point of the vehicle to the time of exiting the intersection, and it is possible to quickly ascertain the position of the tail water vehicle, Thus, it is possible to effectively perform the interception of the tail waggle illegal vehicle at the intersection.

4 and 5, an intersection traffic violation vehicle enforcement system 200 according to a second embodiment of the present invention includes an entrance vehicle detection sensor 210, an advanced vehicle detection sensor 210 ' A photographing apparatus 220, an optical area photographing apparatus 230 for photographing the entire state of an intersection, a vehicle number recognizing camera 240 for determining intermittency, a control unit 250, and a storage unit 260.

In Figs. 4 and 5, the same reference numerals are given to the same components as those described in Figs. 1 and 2 above.

The incoming vehicle detection sensor 210 includes a plurality of first to fourth geomagnetic sensors 211, 212, 213, 214 installed adjacent to a stop line 13 of the road and embedded in the bottom of the road. The geomagnetic sensors 211, 212, 213 and 214 are for sensing the entrance of vehicles into each intersection 10 for each lane of the road and are preferably installed between the stop line 13 and the pedestrian crosswalk 11 . When the pedestrian crossing pedestrian 11 is not present in the intersection 10 (for example, when a pedestrian or the like is installed), the pedestrian crossing is installed between the stopping line 13 and the intermittent area 12 in the intersection 10. The plurality of geomagnetic sensors 211, 212, 213, and 214 detect the entry of the vehicle through the change of the magnetic force by the vehicle made of metal when the vehicle comes in. The geomagnetic sensors 211, 212, 213, and 214 detect the entry of the vehicle, and the sensed information is transmitted to the controller 250. Here, the geomagnetic sensors 211, 212, 213, and 214 each have their own installed location information, and therefore, when detecting the vehicle, the geomagnetic sensors 211 and 212, and the location information (identification information) are transmitted to the controller 250 together with the vehicle detection information. Accordingly, in the case of a four-way intersection, for example, the control unit 250 accurately recognizes which lane the vehicle has entered into the intermittent area 12 of the intersection 10, It is possible to control the display unit 220.

The outgoing vehicle detection sensor 210 'senses a vehicle departing from the intersection 10 in the intermittent area 12 of the intersection 10 and includes first to fourth geomagnetic sensors 211', 212 ', 213' 214 '. As shown in FIG. 5, the geomagnetic sensors 211 ', 212', 213 ', and 214' are located on the lane adjacent to the pedestrian crosswalk 11 of the intersection 10, Thereby sensing the vehicle leaving the intersection 10. The advanced vehicle detection information sensed by the plurality of geomagnetic sensors 211 ', 212', 213 ', 214' is transmitted to the controller 250. Then, the (control unit) drives and controls the intermittent confirmation vehicle number recognition camera 240 so as to photograph the area where the advanced vehicle is sensed, that is, trekking control to photograph the advanced vehicle and recognize the vehicle number. Accordingly, the control unit 250 cancels the data corresponding to the recognized vehicle number.

The entrance vehicle photographing apparatus 220 includes first and second entry vehicle number recognition cameras 221 and 223 for photographing a vehicle entering the intermittent area 12 in the intersection 10 in the direction opposite to each other, And first and second pan tilting drivers 222 and 224 for pan tilting driving the first and second entering vehicle number recognition cameras 221 and 223.

When the first and second entry vehicle number recognition cameras 221 and 223 detect the entry of the vehicle by the geomagnetic sensors 211, 212, 213 and 214, the first and second entry vehicle number recognition cameras 221 and 223 photograph the detection area based on the sensed signal, .

The first and second entering vehicle number recognition cameras 221 and 223 are driven by the first and second fan tilting driving units 222 and 224 in a pan tilting mode to change the display signal of the intersection traffic light 183 The first and second entering vehicle number recognizing cameras 221 and 223 are controlled by the first and second entering vehicle number recognizing cameras 221 and 223 so that the first and second entering vehicle number recognizing cameras 221 and 223 can take a picture do. The first and second fan tilting drivers 222 and 224 are controlled by the controller 250 and are driven and controlled in conjunction with the control signal of the traffic signal 181. [

The optical area photographing apparatus 230 photographs the entire intermittent area 12 of the substantially rectangular four angles divided by the pedestrian crosswalk 11 in the intermittent area 12 of the intersection 10, . In the optical region photographing apparatus 230, all the vehicles entering the intermittent region 12 in the intersection from the opposite directions are photographed so as to be included in one image frame. Accordingly, a plurality of entry vehicles photographed by the first and second entry vehicle number recognition cameras 221 and 223 can be tracked and monitored independently within one frame, respectively. For this, the control unit 250 assigns an identification number (ID) to each entry vehicle photographed at the entry vehicle photographing apparatus 220 upon entering the intersection 10 and recognized as a number, and the assigned identification number (ID) It is possible to continue to track the vehicle-specific movement until it passes over the intersection 10,

As described above, the optical area photographing device 230 photographs the entire area of the intersection 10 and distinguishes the entry vehicles by objects and tracks the movement, so that it can be confirmed that the vehicle passes straight ahead, leftward, and rightward.

The intermittent confirmation number recognition camera 240 obtains the vehicle number by interrupting the vehicle staying in the intermittent area 12 in the intersection 10 in a state where the traffic signal for passing the intersection is changed, that is, It is preferable that the intermittent confirmation number recognition camera 240 is a so-called speed dome camera which is installed to be traced so as to locate and photograph a traffic violating vehicle located in the intermittent area 12. [ Therefore, the speed dome camera receives the position information of the entering vehicles located in the intermittent zone 12 in the non-valid state of the intersection 10 through the optical zone photographing apparatus 230, Obtain the vehicle number by photographing the traffic violation vehicle that is staying.

The traffic-infringing vehicle photographing image and the vehicle number information captured and obtained by the intermittent confirmation number recognition camera 240 are transmitted to the control unit 250. [

In addition, the intermittent confirmation number recognition camera 240 receives the advanced vehicle detection signal from the advanced vehicle detection sensor 210 'and is tracked and driven so as to acquire the vehicle number of the advanced vehicle by photographing the corresponding position, And obtains the vehicle number, and the obtained entry vehicle number is transmitted to the control unit 250. [

The control unit 250 stores the traffic-infringing vehicle photographing image and the vehicle number obtained in the disconnection confirmation number recognition camera 240 and the vehicle number in the storage unit 260. More preferably, The vehicle determined as the offending vehicle matches the photographed image information photographed upon entry into the intermittent area 12 of the intersection 10 and stores the information together in the storage unit 260. [ In addition, the control unit 250 reduces the amount of processing data by destroying data corresponding to the advanced vehicle number acquired based on the information detected by the advanced vehicle detection sensor 210 '.

In addition, the optical area photographing device 230 can photograph the intersection vehicle signal lamp 183 of the intersection 10 together so that it can be used as evidence data at a later time. That is, the vehicle number of the illegal traffic vehicle is photographed and recognized in the intermittent confirmation number recognition camera 240, and at the same time, the traffic illegal vehicle and the intersection traffic light 183 are displayed together in the image frame By photographing, it is possible to obtain evidence for interception and processing of illegal traffic vehicles. These pieces of evidence data are separately stored and managed in the storage unit 260.

When the entrance of the vehicle is detected by the geomagnetism sensors 211, 212, 213, and 214, the control unit 250 controls the first and second entering vehicle number recognition cameras 221 and 223 to independently photograph the area where the detection signal is generated , The vehicle number of the vehicle entering the intermittent area 12 of the intersection 10 can be recognized.

The control unit 250 stores the information obtained in response to a predetermined control signal, that is, the traffic violation vehicle interception information, in the storage unit 260, when the remote server 20 requests it, and the transmission / reception unit 170 To the remote server (20). Therefore, the remote server 20 can receive the interception information for the traffic violation interrupting vehicle in each of the intersections at various places, and collectively process the information.

4, 5 and 6, the entrance vehicle detection sensor 110 detects a vehicle entering the intersection 10 (S30).

If the vehicle is detected in step 210, the controller 250 determines whether the time when the vehicle is detected is a day or a night (S31).

If it is determined in the step S31 that it is nighttime, the control unit 250 controls the lighting device 290 to be turned on in conjunction with the photographing operation of the entrance vehicle photographing apparatus 220 and the optical area photographing apparatus 230, (S32).

In step S33, the control unit 250 selectively drives and controls the first or second entry vehicle number recognition cameras 221 and 223 so as to photograph the area where the vehicle is sensed and photograph the vehicle.

The control unit 250 checks whether the vehicle number of the vehicle is recognized from the photographed image (S34). If not, the control unit 250 generates a time code for each vehicle based on the shooting time (S35).

If the vehicle number is recognized in step S34, the control unit 250 assigns a unique identification number (ID) to each vehicle, and performs matching on a vehicle-by-vehicle basis (S36).

On the other hand, if it is determined in step S40 that the state of the vehicle signal lamp is an effective display state, the control unit 20150 extinguishes all data acquired for the advanced vehicle (S43).

When it is confirmed that the present signal is changed and the present signal of the vehicle signal lamp 183 is transferred to the other side (S44), the controller 250 turns the signal to the position of the present signal transitioned to the photographing direction of the entering vehicle photographing apparatus 220 (S45). In other words, the control unit 250 drives and controls the first and second fan tilting drivers 222 and 224 to switch the shooting direction of the first and second entry vehicle number recognition cameras 221 and 223, So that the user can take a picture of the entering vehicle.

Then, the side where the traffic signal is switched continuously detects the incoming vehicles, recognizes the numbers, tracks them, and interrupts the traffic violating vehicle.

As described above, as described above, the entrance vehicles in the intersection 10 are photographed to recognize the number, the position of the recognized vehicles is tracked by object, and the traffic violation vehicle, that is, It is possible to precisely control the tail water vehicle. That is, it is possible to acquire advanced vehicle information while tracking the position from the entry point of the vehicle to the exit of the intersection, and to locate the tail water vehicle on the basis of the effective display state, Of course, it is also possible to obtain the evidence of the traffic violation based on the information of the vehicle which is not detected by the advanced vehicle detection sensor 210 'even when the present state is not valid. Therefore, Can be performed.

In addition, it is possible to accurately confirm the direction of the entry vehicle through the advance vehicle detection information at the advanced vehicle detection sensor 210 ', so that not only the interception of the tail water vehicle but also the interception of the illegal straight vehicle, .
