Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CCTV illegal parking control system,

The present invention relates to a CCTV illegal parking regulation system by tracking a moving vehicle, and more particularly, to a system for controlling a CCTV illegal parking system by tracking moving vehicles, moving vehicles, The present invention relates to a CCTV illegal parking control system by tracking a moving vehicle so that a vehicle can be controlled even if the vehicle is parked in a blind spot by covering an adjacent vehicle or an obstacle.

As the number of vehicles moving on the road increases, the roads do not increase relative to the increase in the number of vehicles traveling on the road. Therefore, the width of the roads becomes relatively narrow and traffic congestion occurs. Especially, The vehicles that are parked regularly narrow the width of the roads to obstruct the smooth flow of the vehicle, thereby increasing traffic congestion and causing traffic accidents. Therefore, the administrative agency in the jurisdiction may visit the illegal driving car site directly to arrange for the issuance of stickers, or install a CCTV camera in the area where the illegal driving accident occurs.

Conventional CCTV illegal parking control system is composed of a combination of a parking detection camera that monitors illegal parking prohibited areas and a camera that can operate pan and tilt with a zoom lens for car number recognition and extended shooting. Detects and enforces a parked vehicle in the area.

Detecting whether a vehicle has entered an illegal park area, a pseudo-range camera uses a camera with a short focal length to detect a wide range of vehicles from the maximum sensing distance to the minimum sensing distance. As described above, a diaphragm-sensing camera using a camera having a short focal length is unable to recognize the vehicle number because the subject is small and distorted due to the image input to the wide sensing area.

Thus, in the conventional CCTV illegal parking regulation system, when the vehicle enters the illegal parking prohibition area, it is determined that the vehicle enters the input image of the parking detection camera and the vehicle is stopped for a certain period of time. , The number-recognizing operation is performed on the first shot image obtained by zooming-in, the two-shot image is taken after zooming out, and the interrupting operation is started.

When the intermittent vehicle exceeds the allowable time limit without moving from the same position, the intermittent camera rotates and captures three images for interrupted completion and four images of the zoomed out image, and terminates the interrupted operation.

In this way, a series of enforcement procedures that manage the elapsed time of the vehicle after detecting the entry of the vehicle and complete the enforcement is performed by analyzing the image transmitted from each sensing camera by the enforcement server, And progress of interception is carried out.

Usually, one CCTV illegal parking control system can detect up to 200 meters in front of and 100 meters in front of the one-way parking area. In the middle of it, there are two cameras for detecting the front and back of the parking lot and one camera for controlling the zoom lens pan tilt camera. In the case of a crossroad, it consists of 4 cars for detection of vehicles entering the 4-way parking area and 1 for intermittent cameras.

There are three operating modes of the conventional CCTV illegal parking control system: a manual intermittent mode, a semi-automatic intermittent mode, and a fully automatic intermittent mode without an intermittent operation.

Thus, in the case of the conventional CCTV illegal parking control system, the intermittent camera zooms in by recognizing the number after a predetermined time has elapsed after the vehicle is stopped for parking, so that when the vehicle enters the blind spot and is parked, There was a problem.

In other cases, there is a problem that when the driver parks in the prohibited parking area and the license plate camera is deliberately zoomed in before zooming in, the control can not be interrupted.

As shown in FIG. 1, the CCTV illegal parking interception system according to the present invention includes a car number recognition camera 10, a omnidirectional tracking camera 20 for tracking a moving vehicle, an intermittent camera 30, And the disconnection server 40 is connected to an Ethernet 50 constituting a communication path for information communication.

A video signal photographed by each of the cameras 10, 20 and 30 is transmitted to the Ethernet 50 via the hub 50 and a hub (not shown) between the Ethernet 50 and the cameras 10, 20, 50 to the illegal parking intermittent server 40 or to transmit the control signal output from the illegal parking intermittent server 40 to each of the cameras 10, 20 and 30. In addition, the hub may have a function of supplying driving power to each of the cameras 10, 20, and 30.

First, the car number recognition camera 10 will be described. The car number recognition camera 10 photographs the license plates before entering the illegal parking intermittent area for all lanes capable of entering the illegal parking intermittent area, And transmits the image of the license plate to the car number recognition module 60.

The car number recognition module 60 analyzes the car license plate image to recognize the car number and transmits the recognized car number to the illegal parking restriction server 40 via the Ethernet 50. [ The car number recognition module 60 may be mounted in the car number recognition camera 10 or may be installed in the intermittent server 40 or may be installed independently.

When the control server 40 receives the vehicle number recognized as described above, the position calculation module 42 analyzes the vehicle license plate image to detect the position of the vehicle in which the vehicle license plate is photographed, And stores the number in the database 46 in association with the location information.

It is preferable that the car number recognition camera 10 is composed of a high quality camera so as to increase the recognition rate of the car number for the moving vehicle in the multi lane. It is preferable to install one each.

The omnidirectional tracking camera 20 transmits an image of the illegally parked intermittent intermittent area to the vehicle tracking module 70.

The vehicle tracking module 70 extracts a moving object or a vehicle from the image received from the vehicle tracking module 70, thereby continuously tracking movement, parking, and advancement of the vehicle. The vehicle tracking module 70 may be mounted in the omnidirectional tracking camera 20 or may be mounted in the intermittent server 40 or independently installed.

The omnidirectional tracking camera 20 is capable of capturing an image of 360 degrees in one direction by capturing a plurality of cameras simultaneously at the same time. For example, four cameras are arranged at an angle of 90 degrees, .

The image captured by the omnidirectional tracking camera 20 includes a plurality of vehicles so that the vehicle tracking module 70 can simultaneously track the movement of various vehicles at the same time.

The intermittent camera 30 receives the control signal from the illegal parking intermittent server 40 and photographs the intermittent vehicle that exceeds the allowable time limit for the intermittent vehicle. The intermittent information is photographed and transmitted to the illegal parking intermittent server 40 through the Ethernet 50 and stored in the database 46 so as to be utilized as intermittent information.

The intermittent camera 30 includes a so-called PTZ camera having a function of rotating the camera, a function of adjusting the vertical angle, and a function of zooming in / zooming out. As shown in FIG. 3, It is preferable to photograph the front or whole exterior of the vehicle or to photograph the vehicle together with the surrounding environment including the vehicle to be intercepted.

2 is a view showing an installation state of a camera system according to the present invention and shows that a car number recognition camera 10, an omnidirectional tracking camera 20 and an intermittent camera 30 are installed at a predetermined height in a fixed post 100 . In particular, the cameras may be mounted on a fixed bar connected to the fixed post 100 in a cantilevered manner in a horizontal direction so as to facilitate capturing a surveillance area.

On the other hand, the position calculation module 42 provided in the illegal parking intermittent server 40 analyzes the image information received from the car number recognition camera 10 and the omnidirectional tracking camera 20 to extract the vehicle as a moving object, And stores it in the database 46 in connection with the vehicle number recognized by the vehicle number recognition module 60. [

The position calculation module 42 determines the position of the vehicle using, for example, a relative coordinate system. That is, a specific point of the parking monitoring area is defined as a coordinate origin, a road surface which is centered on the coordinate origin is defined as an X-axis plane, a plane perpendicular to the road surface passing through the origin of coordinate, Dimensional coordinate system in which the plane perpendicular to the road surface passing through the vehicle and running perpendicular to the vehicle running direction is the Y axis plane.

The method of setting the actual coordinate system is based on the point where the fixed post 100 for installing the camera system is installed in the parking monitoring area drawing as a reference point, and the point and the road surface meet to set the coordinate point of the three-dimensional coordinate system (X = 0, Y = 0, Z = 0), and the virtual plane corresponding to the road surface is defined as the X-axis plane of the three-dimensional coordinate system, the virtual plane orthogonal to the X-axis plane and parallel to the road running direction is defined as the Z- A three-dimensional coordinate system is determined by defining a plane orthogonal to the Z-axis plane and a Y-axis plane.

The unit of the three-dimensional coordinate system can be a meter, and when the position of the installed camera is displayed on the drawing, each camera coordinate is determined. The direction of the installed camera is the view vector (x, y, z) of the camera. If the distance between the camera and the vehicle is found, the relative position of the vehicle It can be converted to an absolute coordinate system.

Here, all the cameras 10, 20, and 30 are determined at the time of initial installation, and the car number recognition camera 10 is set as a fixed camera, and a recognition lane interval for car number recognition is determined after installation.

When the intersection of the view vector of the car number recognition camera 10 and the road surface is obtained, the position of the vehicle whose car number is recognized is determined.

The following describes the procedures for entering, moving, parking or passing through the parking surveillance area, and tracking the vehicles entering.

First, when the vehicle enters the parking monitoring area, it is photographed by the tracking camera 20, and the vehicle image is transmitted to the vehicle tracking module 70 so that the vehicle is extracted as a moving object. In this case, if there are several cars, they are extracted as different moving objects.

In addition, the entry vehicle is photographed by the car number recognition camera 10, and the car number plate image is transmitted to the car number recognition module 60. The car number recognized by the car number recognition module 60 is transmitted to the intermittent server 40, and the position calculation module 42 of the control server 40 analyzes the vehicle position from the license plate image and stores the analyzed vehicle position in the database 46.

Then, the control server 40 compares the position information of the vehicle having the vehicle number recognized by the vehicle number recognition module 60 and the position information of the moving object extracted by the vehicle tracking module 70, When the vehicle having the position information is logically connected to the moving object and the recognized vehicle is logically linked with the vehicle number as described above among the images photographed by the tracking camera 20, Thereby tracking the movement.

When the interception server 40 tracks the moving position of the moving object extracted from the images photographed by the tracking camera 20 and it is determined that the vehicle being traced is moving in the prohibited area, , It is judged whether or not the time limit is exceeded.

At this time, if the vehicle is parked on the road beyond the allowable time limit, the intermittent Gamera 30 is driven to acquire the intermittent image.

As shown in FIG. 3, the intermittent image includes a vehicle license plate photograph (FIG. 3 (a)) extracted from an image photographed by the vehicle identification camera 10, an illegal parking area 3 (b)), a license plate photograph (FIG. 3 (c)) photographed on a driving car, and a surrounding photograph including an illegal driving vehicle so that the illegal parking position can be confirmed (FIG. 3 (d)) may be acquired and stored in the database 46. The intermittent video information includes a photographing time as well known.

In addition, if the illicit parking vehicle is detected as described above, the moving picture photographed by the tracking camera 20 is extracted from the time when the illegally parked vehicle starts to enter the parking monitoring area to the time when the illegal parking vehicle enters the parking monitoring area, ). ≪ / RTI >

By tracing the movement of the vehicle as a moving object associated with the vehicle number until the vehicle begins to enter the parking monitoring area, the vehicle can be parked in a blind spot where the vehicle number is not visible in the parking monitoring area, Even if the vehicle number is not visible by the vehicle or the vehicle number is displayed, it is possible to accurately detect whether the vehicle is illegally parked.

When the intermittent driving vehicle 40 stores the intermittent image of the illegally parked vehicle, the illegally parked vehicle travels from the time when the illegal driving vehicle enters the parking monitoring zone to recognize the vehicle number, And the image transmitted from the mobile terminal 20 may be stored as a moving image in the database 46. The moving picture may be used as interception evidence data if the vehicle number is not confirmed in the intermittent video.

In addition, the control server 40 displays an image transmitted from the car number identification camera 10, the omnidirectional tracking camera 20 or the intermittent camera 30, and detects the state of entry, movement, (Not shown) for allowing the manager to visually confirm the vehicle number, and a vehicle number recognized by the vehicle number recognition module 60 is connected to the vehicle displayed on the monitor, And can be stored in the database 46 so that it can be used as evidence for controversy about the illegality of illegal parking.
