Description

Traffic Regulations System and Control Method by Image Processing {Traffic Regulations System and Control Method by Image Processing}

The present invention relates to a device and a control method for cracking down on traffic law violation vehicles. In particular, accidents are generated through real-time images transmitted from central control and monitoring stations as well as traffic law violations such as dedicated lane violations, speed violations, and traffic signal violations. The present invention relates to a traffic regulatory violation enforcement device and a control method thereof, which facilitates the flow of traffic by detecting various traffic information such as traffic volume, and permits unmanned enforcement of traffic violation violation vehicles.

As vehicles are recognized as essential means of today, the number of vehicles is rapidly increasing, and the safety and speed of transportation are not reaching their original purpose due to chronic delay and traffic accidents caused by the increase of vehicles. The main cause of traffic accidents is the violation of the driver's traffic laws, so it is essential to crack down on the driver's violation of the traffic laws.

Currently, the enforcement of traffic violations is operated by a system in which traffic police detects a vehicle that violates an intersection or a crosswalk signal, and issues a violation notice. There is a lot of work, and a large number of people are needed to detect violations. In addition, when drivers do not have enforcement police, many drivers ignore traffic laws and cause accidents.

It is also possible to use an unmanned enforcement device to crack down on traffic laws. The unmanned enforcement device cuts the road surface and recognizes the presence of the vehicle through means such as a loop detector to detect traffic signal violations, speed violations, and dedicated lane violations. The device differs in each processor and system for each broken down item such as traffic signal violation, speed violation, dedicated lane violation, etc., and is equipped with a processor corresponding to the broken down item for each installation site, and accordingly, The device is installed and processed.

Each traffic signal violation enforcement device, speed violation enforcement device, dedicated lane violation control device, etc. are individually installed by one system for each item, and the devices required for each area are installed and used. As such, the conventional unmanned enforcement devices have a functionally independent state, meaning that a separate device exists according to one purpose, such as traffic signal violation or speed violation escape vehicle detection. These unmanned enforcement devices will also handle multiple cameras on their respective processors.

According to the conventional unmanned enforcement device, if a violation vehicle is detected through the recorded image of the vehicle traveling at a certain speed over a certain speed such as a speed violation, there is no problem, but after the vehicle enters the control point, In the case of traffic signal violations and dedicated lane violations that must satisfy the conditions of the violation, many problems have been raised with conventional apparatuses that photograph simple points.

The present invention in order to solve the above problems in a road with a signal such as an intersection, crosswalk, etc. dedicated lane violations, speed violations, traffic signal violations by taking a picture of the violation of the vehicle to the offender to the offender By eliminating the application of violations, the seizure of traffic violation vehicles can be operated as an unmanned enforcement device to reduce the waste of manpower. In addition, traffic information such as traffic volume and traffic accidents as well as traffic law violations can be delivered to the central control and monitoring centers to induce smooth traffic flow, and accurate detection of traffic law violations and traffic information can be detected using these images. I did it.
