Description

Off-road parking management system using mobile vehicle tracking and its method

The present invention relates to an off-road parking management system and a method for tracking a moving vehicle, and more particularly, a parking management server for a plurality of vehicles at the same time, the vehicle is connected to the vehicle number immediately before the vehicles enter the off-road parking area. The present invention relates to an off-vehicle parking management system and a method for tracking an off-vehicle parking management system to enable integrated control of an off-road parking management area by performing real-time tracking through moving, entering, parking, and exiting.

In general, the off-road parking lot refers to a parking space or a parking facility in a vacant lot with no roof outside the road, unlike a street parking lot that allows parking by placing a parking compartment on the road. When conducting projects for industrial complex development projects, urban redevelopment projects, urban railroad construction projects, and other complex projects, more than a certain number of off-street parking lots should be installed. In addition, the manager can receive parking fees from the person who parks the car in the parking lot.

By the way, such off-street parking lot is small and small because it is installed in the open ground outside the road surface. Therefore, most of the manned parking management system where the parking officer manages the vehicle parking time and collects the fee, but it is difficult to manage the parking officer's meals or toilets for personal use, and the spatial management of the personnel in charge of the management area size is difficult. Existed.

On the other hand, when the off-street parking lot is operated as an unmanned parking management system, each control facility and unmanned payment machine must be provided for each parking lot, so it costs a lot for installation and maintenance. There was a difficulty in introducing an unmanned parking management system with high initial investment cost.

In addition, an entrance control parking circuit breaker is installed at the entrance of the parking lot, and an entrance control parking circuit breaker is installed at the exit, and a parking blocker is detected at the entrance bottom of each parking circuit breaker by detecting a vehicle approaching or entering the parking lot. An entrance detection loop sensor is installed in a landfill, while an exit detection loop sensor is detected at the exit bottom of each parking breaker to detect a vehicle entering or exiting the parking lot and to drive the parking breaker to the closed state again. Should be landfilled. Accordingly, the installation work for connecting the entrance detection loop sensor or the entrance detection loop sensor to the floor and connecting the breaker or the controller is complicated. When the parking breaker is installed adjacent to the roadside, the entrance detection loop sensor or the entrance detection loop sensor is complicated. It was difficult to install the roof sensor on the side of the road. Accordingly, when the parking blocker was installed inside the parking lot from the side of the road, there was a problem in that the parking lot utilization area was reduced.

In order to control the operation of each field facility in the parking management server 70, the control signal output from the parking management server 70 may be transmitted to each field facility. In addition, the hub may have a function of supplying driving power to each field facility.

First, the license plate number camera 10 is described, the license plate number camera 10 is a high-quality license plate license plate immediately before a vehicle entering the parking area 100 of the off-road parking lot passes through the parking blocker (40). Shooting, and transmits the photographed vehicle license plate image to the vehicle number recognition module 71 of the parking management server (70).

The vehicle number recognition module 71 is configured to recognize the vehicle number by analyzing the received license plate image. The vehicle number recognition module 71 is illustrated as being mounted in the parking management server 70 in the present embodiment, but is mounted in the vehicle number recognition camera 10 or independently configured to manage the parking management server 70 through a network. It may also be connected to.

The vehicle number recognition module 71 recognizes the vehicle number as described above, and at the same time, the position calculation module 72 analyzes the image of the vehicle in which the vehicle license plate is photographed, detects the position of the vehicle, and detects the vehicle of the detected vehicle. The number is stored in the database 80 as a new record in association with the location information.

Such a vehicle identification camera 10 is a narrow angle as shown by the A in Figure 2, unlike the wide-angle omnidirectional camera that can shoot a large area to increase the recognition rate of the vehicle number for the vehicle entering the parking lot entrance. It is preferable to configure a camera capable of shooting in high quality.

The omnidirectional tracking camera 20 transmits the parking zone image photographing all the parking zones 100 in the parking lot to the vehicle tracking module 73 of the parking management server 70, as indicated by C in FIG. 2.

The vehicle tracking module 73 extracts the vehicle as a moving object from the parking area image received from the omnidirectional tracking camera 20, and continuously tracks the movement, parking, and entrance of the extracted moving object. The vehicle tracking module 73 is illustrated as being mounted in the parking management server 70 in this embodiment, but is mounted in the omnidirectional tracking camera 20 or independently configured to be connected to the parking management server 70 through a network. It may be.

In the illustrated embodiment, an entrance control parking blocker and an entrance control parking blocker are shown as one example.

The entrance control parking blocker is lowered in the horizontal direction and kept closed so that the vehicle cannot enter or exit, but the parking is set at a position where the vehicle number of the vehicle can be checked when the vehicle approaches the parking entrance to park the off-street parking lot. When the vehicle number is recognized while passing through the breaker open position, the vehicle is rotated upward and operated in an open state so that the vehicle can pass through, and the vehicle is outside the operating range of the access control parking breaker, that is, the entrance control parking breaker is closed. When it is determined that the vehicle has passed through the closed position of the parking blocker, which is set in a position that does not collide with the vehicle, the vehicle descends to the horizontal direction again and operates to control the entry of the next vehicle.

Similarly, the entrance control parking blocker stops the vehicle approaching the parking lot entrance once it is confirmed that the parking fee has been settled when passing through the parking blocker open position so that the vehicle can pass through. If it is determined that the parking blocker closed position is set in a position outside the operation range of the entrance control parking blocker, it is closed to operate again to control the entry of the next vehicle.

To this end, it is necessary to detect whether the vehicle has approached the parking breaker opening position set at a predetermined position on the entrance side of the parking blocker and whether the vehicle has passed the parking breaker closing position set at the predetermined position on the entry side. In the present invention, whether the vehicle has reached the parking breaker open position and the parking breaker closed position is analyzed by a non-contact method by analyzing an image taken in stereo by a stereo camera.

The stereo camera employed in the present invention comprises a stereo camera in which two cameras are arranged in parallel, extracting a vehicle that is a moving object from image signals simultaneously captured by the two cameras, and extracting the moving object according to binocular disparity. It is made to obtain location information.

The stereo camera 30 is to detect the position of the vehicle to detect whether the vehicle approaching the parking blocker 40 has reached the parking breaker open position or closed position, including a laser range finder and distance measurement It may be replaced by a range finder of other means.

On the other hand, unmanned parking fee calculator 50 may be installed as a field facility. When the unmanned parking fee calculator 50 enters the vehicle number, the vehicle number is transmitted to the charge settlement module 74 of the parking management server 70, and the charge settlement module 74 analyzes the parking time of the vehicle. The parking fee corresponding to the parking time is transmitted to the unmanned parking fee checker 50 and displayed, and the parking fee can be settled by cash or a card through the unmanned parking fee checker 50. Parking fee payment information performed by the user is stored in the database 80 in association with the vehicle number.

In addition, as another embodiment for calculating the parking fee, the unmanned parking fee calculator 50 is provided with a monitor that displays an image of the parking area photographed by the omnidirectional tracking camera 20, the monitor is formed of a touch panel For vehicles that appear in the parking area image displayed on the monitor, vehicle numbers may be superimposed as described above. Thus, when the driver touches his vehicle while checking the vehicle number of his vehicle in the image of the monitor instead of inputting his vehicle number through the keypad of the driverless parking fare calculator 50 to set the parking fee, the driver touches his vehicle. The vehicle number may be transmitted to the charge settlement module 74 of the parking management server 70 to perform the charge settlement operation.

Meanwhile, the vehicle number recognition module 71 provided in the parking management server 70 extracts the vehicle number from the high-quality license plate image received from the vehicle number recognition camera 10 and stores the vehicle number in the database 80 as described below. Connect with location information and save.

In addition, the position calculation module 72 analyzes the image information received from the vehicle number recognition camera 10 and the omnidirectional tracking camera 20 to extract the vehicle as a moving object, calculate the position of the vehicle, and then recognize the vehicle number. In connection with the vehicle number recognized by the module 71 and stored in the database (80).

The position calculation module 72 determines the position of the vehicle using, for example, a relative coordinate system. That is, the specific point of the parking area is designated as the coordinate origin, and the road surface meeting with the coordinate origin is centered on the X axis plane and the road surface passing through the coordinate origin, and the plane parallel to the vehicle driving direction is defined as the Z axis plane and the coordinate origin. A three-dimensional coordinate system in meters in which the Y axis plane is a plane perpendicular to the road driving direction and orthogonal to the vehicle driving direction can be used.

The actual coordinate system setting method determines the point where the camera system is installed in the parking area drawing as the reference point, and determines the point where the reference point meets the road surface as the coordinate origin (X = 0, Y = 0, Z = 0) of the 3D coordinate system. The virtual plane corresponding to the road surface is orthogonal to the X axis plane and the X axis plane of the three-dimensional coordinate system, and the virtual plane parallel to the road driving direction is the Z axis plane, and the plane perpendicular to the X axis plane and orthogonal to the Z axis plane. The 3D coordinate system is determined by defining the Y-axis plane.

The unit of the 3D coordinate system may use a meter, and when the position of the installed camera is displayed in the drawing, each camera coordinate is determined. The direction in which the camera is installed is the camera's view vector (x, y, z), and the vehicle position shown in the image is the relative position value of the camera as the relative position value of the vehicle, Can be converted to world coordinate system.

Here, all the

cameras

10, 20, and 30 are determined at the time of initial installation, and the vehicle number recognition camera 10 is a fixed camera, and a recognition area for vehicle number recognition is determined after installation.

In addition, if the intersection of the view vector and the road surface of the vehicle identification camera 10 is obtained, the position of the vehicle recognized by the vehicle number is determined.

Next, the tracking operation of the vehicle that the vehicle tracking module 73 enters, moves, stops or passes through the parking area will be described.

2 is a view showing a state of extracting and tracking a vehicle entering and exiting an off-road parking lot as a moving object according to the present invention, and the vehicle number recognition camera 10 and the stereo camera 30 may photograph the entrance to the parking lot in front. Is installed at a predetermined position, the omnidirectional tracking camera 20 is installed at a position capable of shooting the parking area 100 as a whole. The omnidirectional tracking camera 20 is operated by an object tracking method, and can detect up to 240 meters on both sides of 120 meters each way, but only one example is installed in the illustrated example, but the parking area is wide or curved. If it is impossible to photograph the entire parking area with a dog, a plurality of vehicles are installed so that the entire parking area can be photographed.

First, when the vehicle approaches the parking blocker 40 from the outside of the parking area 100 to park in the parking area 100, the vehicle number recognition camera 10 photographs the license plate of the vehicle approaching vehicle number recognition Transmitting to the module 71, the vehicle number recognition module 71 analyzes the received license plate image to recognize the vehicle number, the position calculation module 72 analyzes the image of the vehicle in which the license plate is photographed Detects the location of the vehicle, stores the detected vehicle number in association with the location information in the database 80, and displays the parking area 100 on the monitor 90, as shown in FIG. Display the vehicle number superimposed on the vehicle.

Subsequently, when the vehicle passing through the parking blocker 40 enters the parking lot, the vehicle is captured by the omnidirectional tracking camera 20 immediately before passing through the parking blocker 40, and the vehicle image is captured by the vehicle tracking module 73. The vehicle is extracted as a moving object. In this case, when there are several vehicles, they are extracted as different moving objects.

The information of the mobile object extracted by the vehicle tracking module 73 is transmitted to the position calculation module 72 so that the position of the mobile object is analyzed for each mobile object, and a new record is recorded in the database 80 together with the identifier (sequence code). Is stored as.

In addition, the vehicle entering the parking area 100 is taken by the vehicle number recognition camera 10 immediately before passing through the parking blocker 40, the license plate image is transmitted to the vehicle number recognition module 71, the vehicle The number recognition module 71 recognizes the vehicle number from the license plate image and stores the vehicle number in the database 80. Also, the location calculation module 72 analyzes the vehicle position from the license plate image and includes the vehicle number. While storing in 80, the screen displayed on the monitor 90 displays the vehicle number of the corresponding vehicle as the vehicle moves and overlaps with the corresponding vehicle.

Thereafter, the location information of the moving object extracted by the vehicle tracking module 73 is compared with the location information of the vehicle having the vehicle number recognized by the vehicle number recognition module 71, and the vehicle number having the matching location information. And logically connect the moving object, and since the vehicle number is logically connected as described above among the images photographed by the omnidirectional tracking camera 20, the recognized vehicle number is connected and the movement is tracked by connecting with the recognized vehicle number. It is displayed on the monitor 90.

In addition, when the vehicle entering the parking zone 100 is detected as described above, the tracking camera omnidirectionally from the time when the vehicle enters the parking blocker 40 to the time when the vehicle enters the parking zone 100 through the parking blocker 40. The video photographed at 20 may be extracted and stored in the database 80 as a video.

By tracking the movement of the vehicle as a moving object connected to the vehicle number until the vehicle starts entering and exits the parking zone, the vehicle may park in a blind spot where the vehicle number is not visible in the parking zone, If the vehicle number is not visible or the vehicle number is artificially obscured, it is possible to accurately detect whether the vehicle is parked, and the video may be used as evidence in case of a dispute about parking time or parking.

In addition, the parking management server 70 displays an image transmitted from the vehicle number recognition camera 10, the omnidirectional tracking camera 20, or the stereo camera 30, such as entering, moving, stopping, and entering the vehicle. A monitor 90 may be provided to allow a manager to visually check the situation. The vehicle displayed on the monitor 90 may include a vehicle number recognized by the vehicle number recognition module 71 as shown in FIG. 2. By connecting the corresponding vehicle number is displayed to be superimposed can facilitate the parking control of the vehicle.

When the vehicle is approached to the entrance control side open position of the parking circuit breaker 40, the parking circuit breaker control module 75 searches the database 80 to check whether the vehicle is a vehicle having paid parking fee, and pays the parking fee. If the vehicle is confirmed is controlled to open the parking blocker 40 to exit, and if the vehicle has not paid the parking fee can be guided to pay the parking fee without opening the parking blocker (40). In addition, even if the vehicle has paid the parking fee, if the vehicle is determined to be an additional parking fee after a predetermined time elapses after the payment of the parking fee, the vehicle may be guided to pay an additional parking fee.

The database 80 stores the parking information in association with the vehicle number, starting with the vehicle approaching the entrance-side parking circuit breaker 40 and leaving until the vehicle exits the exit-side parking circuit breaker 40. For example, the parking information may include a vehicle number, a parking breaker entry time, a parking breaker leaving time, parking fee, parking fee calculation, etc., and may store a video photographed by the omnidirectional tracking camera 20.

3 is a flowchart illustrating an entry control operation of a parking circuit breaker according to the present invention.

The vehicle number recognition camera 10 may always detect the vehicle entering the parking blocker 40 from the outside by photographing the direction of the parking blocker 40 in the parking area 100 at all times.

In addition, the omnidirectional tracking camera 20 always displays the entire parking area 100 including the outer entrance of the parking blocker 40 and displays it on the monitor 90.

If it is determined that the vehicle approaches the entrance of the parking blocker 40, the vehicle number recognition camera 10 photographs the license plate, and transmits the photographed license plate image to the license plate recognition module 71, the vehicle number. Is recognized and stored in the database 80 as a new record.

In addition, the omnidirectional tracking camera 20 extracts the newly displayed moving object, calculates location information, and stores the location information in the database 80.

In this case, when it is determined that the location information of the vehicle having the vehicle number photographed and extracted by the vehicle number recognition camera 10 and the location information of the moving object photographed and extracted by the omnidirectional tracking camera 20 are determined to be the same, the omnidirectional tracking camera Logically connect the vehicle number taken by the vehicle number recognition camera 10 to the mobile object extracted in 20 to be stored in the database 80 by logically connecting the mobile number extracted from the vehicle number recognition camera 10, and then when the mobile object moves in the omnidirectional tracking camera 20. Logically connect and track the vehicle number every time.

Furthermore, the image captured by the omnidirectional tracking camera 20 is transmitted to the monitor 90 and displayed. In particular, a vehicle in which the vehicle number is logically connected by the above operation is displayed on the screen as shown in FIG. 2. Vehicle supervision can be facilitated by being superimposed on the vehicle, and the vehicle number superimposition display continues throughout the process of entering, moving, parking and leaving the vehicle.

On the other hand, when the vehicle recognizes the vehicle number as described above approaches the parking blocker 40 from the outside analyzes the stereo image transmitted from the stereo camera 30 to determine whether or not reached to the entrance control side open position of the parking blocker. , When it is determined that the entrance control side opening position of the parking circuit breaker is reached, the parking circuit breaker control module 75 controls the parking circuit breaker 40 to be opened, and analyzes the stereo image transmitted from the stereo camera 30 to park the vehicle. It is determined whether the vehicle passing the breaker 40 reaches the entrance control side closed position of the parking blocker, and if it is determined that the vehicle has reached the entrance control side closed position of the parking circuit breaker 40, the parking circuit breaker control module 75 The parking blocker 40 is controlled to be closed.

Subsequently, the vehicle entering the parking area 100 is tracked until the vehicle moves to an arbitrary parking surface and parks. If the vehicle is parked on an arbitrary parking surface, the database 80 stores the parking surface information. The database also stores time information when the vehicle has passed through the parking blocker 40.

If the parking vehicle intends to leave, the parking fee payment is paid directly to the unmanned parking fee payment device 50 or the parking manager before the vehicle is parked in the parking surface or before reaching the opening position on the exit control side of the parking blocker 40. It can be settled by other methods, and the settlement is stored in the database 80 in connection with the vehicle number.
