Description

Control system and device for exclusive lanes {CONTROL METHOD AND APPARATUS FOR EXCLUSIVE ROAD}

The present invention relates to a technology for cracking down a dedicated lane, and more particularly, to a method and an apparatus for cracking down a dedicated lane for cracking down a vehicle illegally driving a lane.

As the social structure becomes more complex and diverse, the area of activity of the individual gradually expands, while the use of automobiles has increased to facilitate this as the rapid movement is required. In addition, due to the development of logistics, the number of vehicles for delivery increased rapidly.

These days, as the social and economic scale expands and becomes more advanced, the demand for vehicles and transportation has exploded, causing serious traffic problems in large cities.

Due to these problems, a special lane system has been recently implemented to allow only city buses and express buses to be used for public transportation on roads with high traffic demands such as urban areas and highways. Examples of the dedicated lane system include a highway bus lane and a bus lane in the city. In particular, the central lane bus lane has been widely implemented in recent years.

However, when an ordinary passenger car or a motorcycle enters into a lane restricted to a bus as described above, a problem arises in smooth public transportation that was originally intended as a dedicated lane system. For this reason, unmanned cameras are installed on roads where dedicated lane systems are implemented or are frequently monitored by crackdown police to crack down on violating vehicles.

However, in the case of unmanned cameras or crackdown police, it is difficult to monitor violating vehicles only at specific places, and it was difficult to proactively monitor the entire area by a dedicated lane.

In order to solve such a problem, there is a conventional patent application No. 10-2007-007487 in the name of a dedicated lane control system. The patent application technology includes a camera module mounted on a bus that runs a bus lane and photographing a bus lane in front of or behind the bus lane; A controller for controlling driving of the camera module, receiving an image captured by the camera module, checking whether there is a violation vehicle in a bus-only lane, and recognizing a vehicle number of the violation vehicle; Disclosed is a dedicated lane control system using a vehicle number recognition system, comprising: a memory storing a vehicle number recognized by a controller and a photographed image.

The above-described prior arts disclose a technique of detecting an interruption section from an image captured by a camera unit, and detecting and notifying a violation vehicle in the case of an interruption section. Since the captured image from the camera performs vehicle recognition for a wide area including an interruption section, there is a problem in that the processing load is large and the processing speed is slow.

In addition, when the enforcement is performed based on the start or end mark of the dedicated lane, there is a problem that even a vehicle that is in normal operation is cracked down due to misrecognition of the start or end mark.

The present invention provides an apparatus and method for exclusively used vehicle violating enforcement, which enforces the enforcement of the exclusive lane violation vehicle when the current position information when the start or end mark of the exclusive lane is recognized and the previously registered exclusive lane position information correspond. Its purpose is to provide.

<Configuration diagram>

The configuration of a dedicated lane violation vehicle control apparatus according to a preferred embodiment of the present invention will be described with reference to FIG. 1.

The dedicated lane violation vehicle control device includes a control module 100, a memory unit 102, a GPS receiver 104, first to third imaging devices 106 to 110, an ultrasonic distance measuring device 112, and a wireless communication module. It consists of 114.

The control module 100 implements a processing process for cracking down a dedicated lane violation vehicle according to a preferred embodiment of the present invention.

The memory unit 102 stores a variety of information including a processing program of the control module 100, and in particular, stores a mapping table that maps position information according to GPS information about starting and ending points of a dedicated lane.

The GPS receiver 104 receives GPS information under the control of the control module 100.

As illustrated in FIG. 2, the first and second imaging apparatuses 106 and 108 are installed on the front left and right sides of the vehicle, and photograph the road surface and provide the imaging information to the control module 100 accordingly. The imaging information from the first and second imaging apparatuses 106 and 108 is for lane recognition.

As illustrated in FIG. 2, the third imaging device 110 is installed on a lower surface of the front headlight of the vehicle, to capture the front surface of the vehicle, and provide the imaging information accordingly to the control module 100. The imaging information from the third imaging apparatus 110 is for recognizing the violating vehicle. Thus, the present invention enables the license plate recognition without being influenced by the external environment as the third imaging device 110 is installed on the lower surface of the front headlight of the vehicle.

The ultrasonic distance measuring device 112 is installed in the front of the vehicle, as shown in Figure 2, to measure the distance to the vehicle located in the front of the vehicle.

The wireless communication module 114 performs communication with a remote server system through a BMS or CDMA or HSDPA communication network, receives violation information from the control module 100, and transmits the violation information to the remote server system.

<Process>

The operation of the above-described dedicated lane violation vehicle control apparatus will be described in detail with reference to the flowchart of FIG. 3.

The control module 100 receives road surface imaging information from the first and second imaging apparatuses 106 and 108 and detects a start lane in a dedicated lane (step 200).

When the bus dedicated start mark is detected (step 202), the control module 100 receives GPS information through the GPS receiver 104 (step 206).

When the GPS information is received, the control module 100 checks whether the received GPS information and the dedicated lane start position information correspond to each other based on the mapping table provided in the memory 102 (step 208). . If the GPS information and the dedicated lane start position information do not correspond to each other, it is determined that the dedicated lane start pattern recognition error is detected, and the process returns to step 200 and the detection of the dedicated lane start mark is continued.

On the other hand, when the GPS information and the dedicated lane start position information correspond to each other, the control module 100 detects the lane pattern of the dedicated lane from the image capturing information from the third imaging apparatus 110 and based on the lane pattern of the dedicated lane. In step 210, the left or right area up to the predetermined distance is determined as the dedicated lane area, and it is checked whether there is a vehicle other than the bus for the determined dedicated lane area. Here, the dedicated lane lane pattern is divided into a dotted line, a solid line, a solid line, and a double line, and the dotted line indicates a section in which the general vehicle can enter and exit, and the solid line indicates a section in which the general vehicle cannot enter or exit the vehicle. The disconnection indicates a part-time operating section of 7:00 am to 10 am, 5 pm to 9:00 pm, and the double track indicates that it is an entire operating section. Accordingly, the interruption time may be obtained through the lane lane pattern. The dedicated lane area detects a lane pattern with a blue dedicated lane as shown in FIG. 4, and determines an area up to a predetermined distance based on the pattern as a dedicated lane area. Alternatively, when the dedicated lane area has another color such as red on the road, the red area may be determined as the dedicated lane area in the imaging area. The presence or absence of the vehicle other than the bus is performed by recognizing the license plate from the imaging information picked up by the third imaging apparatus 110. Of the vehicle license plates, all of the license plates other than the bus license plate become license plates of the crackdown target vehicle.

When the license plate of the vehicle other than the bus is detected in the dedicated lane area, the control module 100 checks whether the current time corresponds to the interruption time according to the lane pattern.

If the current time corresponds to the enforcement time, the control module 100 measures the distance to the enforcement target vehicle through the ultrasonic distance measuring device 112 (step 216). The reason for measuring the distance to the crackdown target vehicle in this manner will be described with reference to FIG. 5. Referring to FIG. 5, when the dedicated lane is terminated at 20 [M], if the vehicle other than the bus is separated by a distance of 20 [M], the vehicle is a crackdown target. Measure the distance to enable accurate crackdown.

The control module 100 recognizes a vehicle number for a vehicle that is not a bus and receives GPS information when the distance to the crackdown target vehicle is within a crackdown distance, which is a distance to an end point of the dedicated lane (step 218). Location detection is performed, and violation information including vehicle image information, recognized vehicle number, detected current location information, and current time information is generated and transmitted to the remote server (step 220).

During the monitoring of the enforcement subject vehicle, the control module 100 checks whether the lane position of the dedicated lane is changed in the imaging information from the third imaging apparatus 110 (step 222).

When the lane position of the dedicated lane is changed in the image pickup information from the third imaging apparatus 110, the control module 100 changes the dedicated lane area corresponding to the changed lane position of the dedicated lane (S224). That is, when the bus moves to another lane as shown in FIGS. 6 to 8, the control module 100 changes the dedicated lane area to correspond to the lane position of the changed dedicated lane, thereby moving the bus to another lane. Even if it is possible to crack down on vehicles other than the bus entering the dedicated lanes.

In addition, the control module 100 receives road surface imaging information from the first to second imaging apparatuses 106 and 108 and detects the end of the dedicated lane during the monitoring of the control subject vehicle (step 226).

When the bus-only end mark is detected (step 226), the control module 100 receives GPS information through the GPS receiver 104 (step 228).

When the GPS information is received, the control module 100 checks whether the received GPS information and the dedicated lane end location information correspond to each other based on the mapping table provided in the memory 102 (step 230). . If the GPS information and the dedicated lane end location information do not correspond to each other, it is determined that the dedicated lane end pattern recognition error is detected and the process returns to step 210 to continue monitoring the subject vehicle, and the GPS information and the dedicated lane location information correspond to each other. When the exclusive lane according to the present invention terminates the service.
