Description

Technology Field

[0001] The present invention relates to a dual-edge type on-street parking management system capable of managing illegal parking in multiple parking lines using a single camera system, and more specifically, to a dual-edge type on-street parking management system capable of managing illegal parking in multiple parking lines using a single camera system, wherein when a first edge terminal monitoring a parking space detects the entry of a vehicle, a second edge terminal identifies the license plate through image analysis, thereby improving the license plate recognition precision and illegal parking management efficiency for a wide parking area. Background Technology

[0003] Recently, the use of on-street parking along roadsides has been increasing to address the shortage of parking spaces in cities. While on-street parking has the advantage of utilizing idle road space without the need to construct separate parking buildings, it presents many challenges in collecting parking fees and managing illegal parking due to frequent vehicle traffic and the difficulty of stationing management personnel.

[0004] Existing on-street parking management systems primarily relied on methods where on-site managers personally patrolled with terminals to check for parking, or installed geomagnetic sensors or cameras at each parking space to determine the presence of a vehicle. However, methods relying on human resources have limitations, such as high labor costs and difficulties in real-time response, while the approach of installing individual equipment for each space suffers from the disadvantage of incurring excessive initial installation and maintenance costs.

[0005] To address these issues, video analysis technologies utilizing high-resolution cameras are being introduced. However, managing extensive on-street parking areas with a single camera leads to a surge in data processing load when recognizing multiple vehicles simultaneously. In particular, the method of transmitting all video footage to a central server for analysis in real time consumes massive network bandwidth and causes bottlenecks where recognition speeds degrade depending on the server's processing performance. Furthermore, the computational structure of existing systems is inefficient for tasks beyond simple vehicle presence detection, such as detecting illegal parking outside parking lines or performing sophisticated license plate recognition.

[0006] Therefore, there is a growing need for edge computing technology that performs primary analysis at camera terminals in the field; however, edge terminals capable of performing high-performance computations are expensive, making it economically burdensome to apply them to all cameras. Accordingly, there is a need for a technical alternative that improves efficiency by hierarchically configuring relatively low-spec and high-spec devices to distribute data processing and precisely analyzing only specific images at the time when a parking event occurs.

[0051] FIG. 1 illustrates the configuration of a roadside parking management system that performs a dual-edge type roadside parking management method for managing illegal parking in a plurality of parking areas according to an embodiment of the present invention.

[0052] A dual-edge type roadside parking management method for managing illegal parking in a plurality of parking areas, performed by a roadside parking management system comprising one or more memories and one or more processors according to an embodiment of the present invention, wherein the roadside parking management system comprises: a first edge terminal receiving a first image capturing a shooting area including a plurality of parking areas; and a second edge terminal receiving a second image capturing a shooting area including a plurality of parking areas and a driving lane adjacent to a parking area; and wherein the roadside parking management method comprises: a parking status information derivation step by which the first edge terminal derives parking status information including whether a vehicle is parked in each of the plurality of parking areas and a parking start time for the corresponding parking area based on the first image; and a parking status information transmission step by which the first edge terminal transmits parking status information for the corresponding parked vehicle to the second edge terminal when the vehicle parked in the parking area has started parking. The method may include: a vehicle number identification step in which the vehicle number of the parked vehicle is identified in a second image in which the parked vehicle is captured, based on parking status information for the parked vehicle, by the second edge terminal; and an integrated information transmission step in which integrated information including parking status information for the parked vehicle and the vehicle number is transmitted to an external server by the second edge terminal.

[0053] In addition, according to one embodiment of the present invention, the vehicle number identification step can identify the vehicle number of the parked vehicle in the second image within a time interval predetermined for the parking start time, based on the parking start time of the parked vehicle derived from the first image.

[0055] In one embodiment of the present invention, the roadside parking management system (1) performing the dual-edge type roadside parking management method may include a first edge terminal (10) and a second edge terminal (11).

[0056] The first edge terminal (10) and the second edge terminal (11) are each computing readable recording media comprising one or more processors and one or more memories, and may each be connected to the first camera and the second camera via wired or wireless connections.

[0057] In one embodiment of the present invention, the first edge terminal (10) includes a parking status information extraction unit (12) and a parking status information transmission unit (13), and corresponds to a computing device that checks whether each of the plurality of parking areas monitored by the first image is parked based on a first image received from a first camera.

[0058] In one embodiment of the present invention, the second edge terminal (11) includes a vehicle number identification unit (14) and an integrated information transmission unit (15), and corresponds to a computing device that identifies the vehicle number of a parked vehicle based on a second image received from a second camera and parking status information transmitted by the first edge terminal.

[0060] In addition, the above-mentioned roadside parking management system (1), preferably the second edge terminal (11), is connected to communicate with an external device or external system such as the server (2) shown in FIG. 1, and can transmit data generated within the above-mentioned roadside parking management system (1) to the external device or external system via a wired or wireless network.

[0062] Specifically, the first edge terminal (10) may correspond to a computing device comprising one or more memories and one or more processors that receives a first image collected in real time from a camera installed to photograph a plurality of parking areas and constantly monitors whether a vehicle is present within the parking area. The first edge terminal (10) may capture a vehicle that enters and stops within a specific parking area for each of the plurality of parking areas and generate parking status information including a parking area number, whether it is parked, and a parking start time.

[0064] The second edge terminal (11) may correspond to a computing device comprising one or more memories and one or more processors, which receives a second image collected in real time from a camera installed to photograph a plurality of parking areas, stores a portion of the second image within the second edge terminal (11), and identifies a vehicle number on the stored second image only when called by the first edge terminal (10). The second edge terminal (11) may identify the vehicle number of a parked vehicle in a vehicle number identification area to be described later, and transmit it to a server together with parking status information generated by the first edge terminal (10).

[0066] Each component included in the above-mentioned roadside parking management system (1) can perform each step of the above-mentioned dual-edge roadside parking management method.

[0068] The above parking status information derivation unit (12) is controlled by the first edge terminal and can perform a parking status information derivation step (S1). Specifically, the parking status information derivation unit (12) compares the coordinate values ​​of each parking area set within the first image with the location of an identified parking vehicle object, and if the parking vehicle enters a specific parking area among a plurality of parking areas and remains stationary without moving for more than a preset threshold time, it determines this as a parking state, records the time at which it is determined to be a parking state as the parking start time, and can derive parking status information including the parking area number where the parking vehicle is parked, the parking start time, and whether it is parked.

[0070] The above parking status information transmission unit (13) is controlled by the first edge terminal and can perform a parking status information transmission step (S2). Specifically, the parking status information transmission unit (13) can convert the parking status information derived from the parking status information derivation unit (12) into a data packet suitable for a wired / wireless communication protocol and transmit it to the second edge terminal (11). This serves as a trigger signal for the second edge terminal (11) to perform the vehicle number identification step (S3) and the integrated information transmission step (S4) that are subsequently performed, and through the information included in the parking status information, the second edge terminal (11) can accurately secure the parking area number and time where the parking event occurred and limit the analysis range of the vehicle number.

[0072] The above vehicle number identification unit (14) is controlled by the second edge terminal and can perform a vehicle number identification step (S3). Specifically, the vehicle number identification unit (14) can select a frame based on the time of the parking start time included in the parking status information received through the parking status information transmission step (S2), among the second images stored in the second edge terminal (11). In the selected frames of the second images, the license plate of the parked vehicle is detected in the vehicle number identification area corresponding to the parking area number included in the parking status information, and the vehicle number can be identified through character recognition operations.

[0074] The integrated information transmission unit (15) is controlled by the second edge terminal and can perform the integrated information transmission step (S4). Specifically, the vehicle number identified in the vehicle number identification step (S3) and the parking status information derived in the parking status information derivation step (S1) can be combined to generate integrated information and transmitted to an external server (2). That is, the integrated information may include one or more of a parking area number, a parking start time, a parking status, and a vehicle number.

[0075] Even if vehicle number identification fails, the server (2) can support administrator verification by transmitting video information based on the parking start time or an identification failure flag.

[0077] In addition, according to one embodiment of the present invention, the first edge terminal transmits a first image to the server, the second edge terminal transmits a second image to the server, and the server can stream the first image and the second image in real time to an administrator.

[0078] A roadside parking management system (1) according to one embodiment of the present invention can provide a real-time streaming function so that a manager can visually check the situation at the site from the outside and respond immediately.

[0079] Specifically, the first edge terminal (10) and the second edge terminal (11) can each convert the collected first video and second video into data for streaming and transmit it to an external server (2). The server (2) relays each received video data in real time through an interface of a manager's terminal or a control system, thereby allowing the manager to simultaneously monitor the overall situation of the entire parking area (first video) and the detailed situation of the area for identifying the license plate of a specific vehicle (second video). In particular, if an unexpected situation occurs where license plate identification is not smooth at the license plate identification unit (14), the manager can directly check the license plate or confirm whether it is illegal parking through the second video streamed in real time and issue a remote instruction.

[0081] FIG. 2 illustrates embodiments of a system implementing a dual-edge type roadside parking management method according to one embodiment of the present invention.

[0082] As illustrated in FIG. 2, the roadside parking management system of the present invention can be physically implemented in various forms of edge terminals, and can be flexibly applied depending on the type of camera and the configuration of the existing roadside parking monitoring system. Specifically, the first edge terminal (10) and the second edge terminal (11) may be configured as separate hardware independent of the camera that performs the video recording function, or may be implemented by being integrated as a software module or embedded form inside the camera.

[0084] FIG. 2(a) illustrates an embodiment in which the first edge terminal (10) and the second edge terminal (11) included in the roadside parking management system (1) each have a configuration of an artificial intelligence camera integrated with a camera that receives a first image and a second image.

[0085] In this case, the first edge terminal (10) and the second edge terminal (11) may each be intelligent AI cameras capable of performing an image analysis function for the first image and the second image, respectively, as well as performing an image shooting function that collects images necessary for each terminal to perform the image analysis function. That is, image analysis is performed simultaneously with image shooting at each of the first edge terminal (10) and the second edge terminal (11), and data generated from each terminal can be transmitted to an external server (2), etc.

[0087] FIG. 2(b) illustrates an embodiment in which a first camera generating a first image and a second camera generating a second image are physically connected to a roadside parking management system (1).

[0088] The first camera and the second camera each transmit the captured first and second images through a network or a dedicated line, and the first edge terminal (10) and the second edge terminal (11) located inside the roadside parking management system (1) each receive the first and second images and perform analysis suitable for their respective purposes. This is effective when attempting to perform the functions described in the present invention by connecting the system without replacing the already installed general cameras.

[0089] At this time, the first camera and the second camera may be IP cameras, and the roadside parking management system (1) may include a decoder that decodes a compressed video signal received through a network, and the decoder may perform the role of the first edge terminal (10) and the second edge terminal (11) to process video analysis. In addition, the first camera and the second camera may be HD-SDI (High Definition Serial Digital Interface) cameras, and the roadside parking management system (1) may be implemented in the form of a video server that converts and processes high-definition uncompressed signals into digital data and perform the functions of the first edge terminal (10) and the second edge terminal (11).

[0091] In one embodiment of the present invention, the first camera and the second camera may be implemented as a single camera. As shown in FIG. 2(c), a single camera (integrated camera) is configured to simultaneously photograph a parking area and a lane, and the camera transmits images to the first edge and the second edge, respectively, and the first edge performs an analysis of the parking area in the image and the second edge performs an analysis of the lane.

[0092] In this case, the integrated camera can simultaneously collect a first image and a second image through one or more lenses and transmit them to a first edge terminal and a second edge terminal, respectively. That is, the functions of the first camera and the second camera, which existed separately in FIG. 2(b), are implemented within a single integrated camera. This allows for the simultaneous generation of a first image and a second image captured at different angles of view or for different purposes within a single device, and transmits them to respective edge processing modules so that parking status determination and license plate identification can be performed in parallel.

[0094] FIG. 3 illustrates the steps of performing a dual-edge type roadside parking management method according to one embodiment of the present invention.

[0096] Referring to FIG. 3, the dual-edge roadside parking management method comprises a parking status information derivation step (S1), a parking status information transmission step (S2), a vehicle number identification step (S3), and an integrated information transmission step (S4). As described above, the parking status information derivation step (S1) and the parking status information transmission step (S2) can be performed through the first edge terminal (10), and the vehicle number identification step (S3) and the integrated information transmission step (S4) can be performed through the second edge terminal (11).

[0098] In the above parking status information derivation step (S1), the first edge terminal can determine the parking status of each parking area in real time based on the first image captured of a plurality of parking areas and derive parking status information.

[0099] Specifically, in the parking status information derivation step (S1), regarding a specific parking area among a plurality of parking areas captured in the first image, if a parking vehicle that has entered from outside the parking area remains stationary inside the parking area for a set time (preferably when there is a change in position less than a set standard), the first edge terminal (10) determines that the parking area is occupied by the parking vehicle, determines the parking status as a parked state, and records the time when the parking status is determined as the parking start time.

[0100] At this time, in order to determine whether the parked vehicle occupies the parking area, the first edge terminal may select and perform a method such as comparing the location coordinates of the center point or bottom ground surface of the parked vehicle object with the coordinate range of the parking area, and calculating and comparing the degree of overlap between the area of ​​the bounding box, which is the outline of the parked vehicle, and the area of ​​the parking area.

[0101] Based on the above process, the first edge terminal can generate parking status information including the parking area number where the parked vehicle is parked, whether it is parked, and the parking start time.

[0102] That is, the first edge terminal (10) monitors the received first image in real time, and if it is determined that a specific parking area included in the first image is in a parked state, it can generate parking status information for the corresponding parking area.

[0104] In the above parking status information transmission step (S2), the first edge terminal (10) transmits the parking status information generated in the above parking status information derivation step (S1) to the second edge terminal (11), and this may serve as a trigger to perform the image analysis function of the second edge terminal (11).

[0105] That is, the first edge terminal transmits data only when an event occurs in which a parked vehicle is parked in a parking area and the parking status is determined to be in a parked state, i.e., when parking status information is generated, thereby controlling the second edge terminal so that it does not perform vehicle number identification operations at all times, but performs vehicle number identification operations only when the parked vehicle is parked in a parking area.

[0107] In the above vehicle number identification step (S3), the second edge terminal (11) can extract the vehicle number of the parked vehicle from the second image stored in the second edge terminal (11) based on the parking status information received through the parking status information transmission step (S2).

[0108] First, in the vehicle number identification step (S3), the second edge terminal (11) stores a portion of the received second image, and when the parking status information is transmitted, the second image can be extracted from the stored second image for a preset time interval based on the parking start time included in the parking status information.

[0109] This allows for the identification of license plates only during time intervals within the second video stored in the second edge terminal where the parked vehicle is highly likely to have existed, thereby preventing the consumption of unnecessary computational resources that would occur when examining all video footage of all time periods, and ensuring data reliability by preventing a situation where the license plate of another vehicle in motion is mistakenly identified as the license plate of a vehicle parked in the corresponding parking area regardless of the parking event.

[0110] Next, the second edge terminal (11) can derive a pre-set vehicle number identification area corresponding to a location based on the parking area number included in the received parking status information in the second image of the extracted pre-set time interval, and can identify the vehicle number of a parked vehicle by applying an artificial intelligence-based character recognition model to the vehicle number identification area. At this time, the artificial intelligence-based character recognition model utilizes deep learning-based optical character recognition (OCR) technology to accurately extract the number plate number within the second image as text data even in various shooting environments such as shadows or light reflections.

[0112] In other words, unlike the first edge terminal which monitors and analyzes the video (first video) received in real time, the second edge terminal does not analyze the received video in real time but only stores a portion of it, and can perform analysis on the stored second video only when it receives a signal from the first edge terminal, that is, when it receives parking status information.

[0114] In the above integrated information transmission step (S4), the second edge terminal (11) can generate integrated information by combining the parking status information generated in the preceding parking status information derivation step (S1) and the vehicle number of the parked vehicle identified in the vehicle number identification step (S3), and transmit the said integrated information to an external system. The external system, such as a server (2), can record the received integrated information to calculate parking fees or provide real-time parking status information to an administrator.

[0115] Even if license plate identification fails, the identification failure status can be transmitted along with partial video data at that point in time, enabling the administrator to verify it directly afterwards.

[0116] Additionally, the above integrated information may be directly transmitted from the second edge terminal (11) to an external server (2) depending on the network configuration environment of the system, or alternatively, it may be implemented in an indirect transmission method in which the second edge terminal (11) transmits the generated integrated information to the first edge terminal (10), and then the first edge terminal (10) collects it and transmits it to the server (2).

[0118] FIG. 4 illustrates the arrangement of a first camera, a second camera, and a plurality of parking areas for collecting a first image and a second image according to an embodiment of the present invention.

[0119] According to one embodiment of the present invention, the first image is an image of a plurality of parking areas arranged according to the driving direction of a vehicle driving in a driving lane in an outer area of ​​a driving lane, and the second image may be an image of one or more driving lanes adjacent to the plurality of parking areas captured by the first image.

[0121] Referring to FIG. 4, the road parking management system may place a first camera and a second camera at specific locations to efficiently manage a plurality of parking areas (1, 2, and 3 in FIG. 4) arranged continuously along the driving direction of a vehicle traveling on the road. The plurality of parking areas are located in the outer area of ​​the driving lane, and each parking area may be composed of an independent section sized to be occupied by one vehicle.

[0123] The first camera can generate a first image by capturing a shooting area that includes a plurality of parking areas. The first camera may be positioned to view the parking status of each parking area from above or to capture the entire parking surface from the side. The first image generated thereby can be analyzed by a first edge terminal and utilized as data to determine the presence or absence of a parked vehicle and its parking location.

[0124] That is, the first camera can be set to a field of view that facilitates the collection of visual data that can accurately determine the parking status of the entire multiple parking area in real time.

[0126] The second camera is positioned spaced apart from the first camera and can generate the second image by capturing a shooting area that includes a plurality of parking areas and one or more driving lanes adjacent thereto. The second camera can be positioned at an angle that effectively captures the front or rear of a vehicle entering a parking area from a driving lane or exiting a parking area from a driving lane. The second image generated thereby can be analyzed by a second edge terminal and utilized as data to identify the license plate number of a parked vehicle.

[0127] At this time, the second image may be generated as an image with a higher resolution than the first image in order to precisely identify the vehicle number.

[0129] Such camera arrangement enables the separate collection of images for determining parking status (first image) and for license plate recognition (second image) within a single system, and by having different viewpoints and resolutions, it can reduce errors in image analysis that occur during the process of managing multiple parking zones simultaneously.

[0131] FIG. 5 illustrates the process of deriving parking status information by a first edge terminal according to an embodiment of the present invention.

[0133] As illustrated in FIG. 5, the first edge terminal (10) can generate parking status information based on a first image received from a first camera.

[0134] Specifically, as illustrated in the example in FIG. 5, when a parked vehicle enters from outside to inside parking area 1, the first edge terminal identifies the object of the parked vehicle within the first image, and if it is determined that the parked vehicle has entered and stopped within parking area 1, the first edge terminal can derive parking status information by recording the corresponding time point t=10 as the parking start time.

[0135] The parking status information derived at this time may include a parking area number (parking area number: 1), a parking start time (parking start time: 10), and a parking status (parking status: parked), as illustrated in the lower right corner of FIG. 5. When the parking status information is generated, the first edge terminal may perform a parking status information transmission step (S2) to transmit the derived information to the second edge terminal.

[0137] FIG. 6 illustrates the process of identifying a vehicle number and transmitting integrated information to an external server by a second edge terminal according to an embodiment of the present invention.

[0138] According to one embodiment of the present invention, the integrated information transmission step may transmit an image of a time interval for a pre-set time interval for the parking start time in the second image to an external server based on the parking start time of the parking vehicle derived from the first image when the vehicle number of the parking vehicle is not identified in the vehicle number identification step.

[0140] As illustrated in FIG. 6(a), the second edge terminal can identify the license plate number of a parked vehicle within a second image stored in the second edge terminal based on the parking status information received from the first edge terminal. As shown in the example of FIG. 6(a), when the parking start time derived from the first edge terminal is t=10, the second edge terminal can extract images before and after the corresponding time point, i.e., images at t=6, 8, and 12, according to a preset time interval among the second images stored internally, and derive the license plate number 1234 of the parked vehicle based on the extracted images.

[0142] Referring to FIG. 6(b), the second edge terminal can generate integrated information by combining the identified vehicle number and parking status information. The integrated information may be configured in the form of a data table containing the vehicle number and parking start time of the vehicle occupying the corresponding area for each parking area number. The second edge terminal transmits the integrated information generated in this way to an external server (2), and the server (2) records the received data in a database so that it can be used as basic data for an administrator to check the real-time parking status or settle fees.

[0144] Meanwhile, an exceptional situation may occur in which the vehicle number is not properly identified during the vehicle number identification step (S3) due to insufficient illumination or obscuring of the license plate. In this case, during the integrated information transmission step (S4) of the present invention, the second edge terminal does not merely send an identification failure flag to an external server, but can also transmit the second video data itself to the server for a preset time interval (t=8~t=12) set around the parking start time (t=10), as illustrated in FIG. 7 (a). The server provides the received video interval to the administrator terminal, and the administrator can fill the operational gap of the system by visually checking the streamed or recorded video and directly inputting the license plate.

[0145] That is, according to one embodiment of the present invention, if vehicle number identification fails, the image at that time is transmitted to a server so that an administrator can verify it afterwards, thereby preventing the omission of illegal parking.

[0147] FIG. 7 illustrates the process of identifying a vehicle number in a vehicle number identification area that includes an image of a time interval set based on the parking start time according to one embodiment of the present invention.

[0148] According to one embodiment of the present invention, the second edge terminal stores a vehicle number identification area in a driving lane for identifying the vehicle number of a parked vehicle parked in each of a plurality of parking areas, and the vehicle number identification step can identify the vehicle number of the parked vehicle in the vehicle number identification area corresponding to the parking area of ​​the parked vehicle identified in the first image in the second image.

[0150] Figure 7 specifically explains the vehicle number identification step of Figure 6 (a) described above.

[0151] Referring to FIG. 7(a), the second edge terminal of the present invention can temporarily store the received second image in internal memory using a time window method. Specifically, the second edge terminal does not permanently store the entire received second image, but temporarily retains only the second image for a predetermined period of time (e.g., the last 10 minutes) in memory, and when new data comes in, deletes the oldest data and continuously stores and manages the second image in its latest state for a certain period of time.

[0152] When the parking start time t=10 of a parked vehicle in a specific parking area is transmitted from the first edge terminal, the second edge terminal can extract only the images corresponding to the preset time interval t=8~t=12 before and after the parking start time from the second images stored in advance and set them as analysis targets for vehicle number identification.

[0154] Referring to FIG. 7(b), the second edge terminal may have a license plate identification area corresponding to each of the multiple parking areas (1, 2, 3) pre-set. The license plate identification area is a type of Region of Interest (ROI) set to include a part of the driving lane within the second image, and may correspond to a coordinate range on the image where the license plate (preferably the license plate) of a parked vehicle entering a specific parking area is likely to be physically located.

[0155] The second edge terminal can identify the parking area number included in the parking status information received from the first edge terminal in the vehicle number identification step (S3), and instead of analyzing the entire frame image of the second image extracted for the preset time interval, it can perform vehicle number identification only within a specific vehicle number identification area corresponding to the parking area number.

[0156] In the example of FIG. 7(b), a parked vehicle enters and is parked in parking area 1, and the first edge terminal stores the parking area number of the parking status information as 1 and transmits it to the second edge terminal. The second edge terminal does not search the entire area of ​​the frame image in each frame image of the stored second image, but rather confirms that the parking area number of the received parking status information is 1 and attempts to identify the vehicle number using only the 'vehicle number identification area of ​​parking area 1' which is mapped to parking area 1 and is pre-configured.

[0157] At this time, other vehicles passing through adjacent driving lanes or identification areas corresponding to the second or third parking areas may be excluded from the analysis. This method can be effective in blocking interference phenomena where the license plate of an unrelated vehicle in motion is mistakenly identified as belonging to a parked vehicle.

[0158] That is, according to one embodiment of the present invention, a vehicle number identification area is pre-set to facilitate vehicle number identification for each parking area, thereby enabling the effect of precisely identifying the vehicle numbers of parked vehicles in multiple parking areas.

[0160] In this way, by combining temporal filtering through the parking start time and spatial filtering through the license plate identification area, the roadside parking management system of the present invention can accurately extract information about a target vehicle that has generated a specific parking event and transmit it to a server, even in an environment where many vehicles move frequently.

[0162] FIG. 8 illustrates a vehicle number identification process performed in the nearest driving lane according to one embodiment of the present invention.

[0163] According to one embodiment of the present invention, the vehicle number identification step may include: a first vehicle number identification step for identifying a vehicle number in the nearest driving lane closest to the parking area among one or more driving lanes captured in the second image; and a second vehicle number identification step for identifying a vehicle number in a driving lane located opposite to the parking area in the nearest driving lane when the vehicle number is not identified in the nearest driving lane.

[0165] The above vehicle number identification step (S3) may attempt to identify the vehicle number by dividing the vehicle number identification area described above according to the driving lane in order to more accurately identify the vehicle number of the parked vehicle.

[0166] The second edge terminal (11) may have a vehicle number identification area pre-set for each of the adjacent driving lane, which is physically in contact with the boundary line of the parking area and is a lane through which a parked vehicle directly enters or passes for parking, and a vehicle adjacent driving lane, which is positioned parallel to the adjacent driving lane and is separated from the parking area by one lane. Each of the adjacent driving lane and the vehicle adjacent driving lane has a vehicle number identification area pre-set for each of the multiple parking areas, and the second edge terminal may perform a first vehicle number identification step of searching for a vehicle number identification area within the adjacent driving lane corresponding to a specific parking area where a parked vehicle is parked, and may perform a second vehicle number identification step of searching for a vehicle number identification area within the vehicle adjacent driving lane corresponding to the parking area according to the result of the first vehicle number identification step.

[0167] That is, the second edge terminal can perform vehicle number identification step by step by setting a vehicle number identification area for each driving lane through which a vehicle passes to park in a parking area.

[0169] In the first vehicle number identification step above, the second edge terminal (11) can perform vehicle number identification based on the nearest driving lane that the parked vehicle must pass just before it reduces speed to park and fully enters the parking area.

[0170] Specifically, the second edge terminal (11) can derive a stored vehicle number identification area within the nearest driving lane associated with the parking area corresponding to the parking area number based on the parking area number included in the parking status information received from the first edge terminal (10), and attempt to identify the vehicle number for the said vehicle number identification area.

[0172] The above second vehicle number identification step may be performed if a valid vehicle number is not obtained in the above first vehicle number identification step.

[0173] If another large vehicle is driving in the nearest driving lane and temporarily obscures the license plate of the parked vehicle, or if the license plate (preferably the vehicle number) is photographed blurry and cannot be identified within the area of ​​the said nearest driving lane due to the sudden entry of the vehicle, the second edge terminal (11) can extend the vehicle number identification range to a pre-set vehicle number identification area within the vehicle-adjacent driving lane. The second edge terminal (11) can derive a pre-stored vehicle number identification area within the vehicle-adjacent driving lane associated with the said parking area and perform vehicle number identification for the said vehicle number identification area.

[0175] Through such a hierarchical identification structure, the roadside parking management system of the present invention can accurately identify and generate vehicles that have triggered specific parking events without missing them, even in complex road environments where multiple vehicles are moving.

[0177] The example in FIG. 8 illustrates an embodiment of the first vehicle number identification step.

[0178] Referring to FIG. 8, when a parked vehicle with license plate number '1234' enters parking area 1, the second edge terminal (11) first performs a first license plate identification step to identify the license plate number for the license plate identification area A1, which is mapped to the first parking area (1) within the nearest driving lane. At this time, when the vehicle passes through area A1 and the license plate is clearly captured, the license plate number can be identified immediately and the license plate identification step can be terminated.

[0179] However, if vehicle number identification fails in area A1, the second edge terminal (11) can immediately switch to the second vehicle number identification step and perform vehicle number identification in area A3, which is mapped to parking area 1 within the adjacent driving lane.

[0180] In this way, by operating multiple identification zones (A1-A3, A2-A4, etc.) along lanes for each parking area, it is possible to achieve the effect of securing vehicle license plates at any point along the entry route.

[0182] FIG. 9 illustrates the process of identifying vehicle numbers in a first adjacent identification area and a second adjacent identification area within a vehicle adjacent driving lane according to an embodiment of the present invention.

[0183] According to one embodiment of the present invention, the first vehicle number identification step identifies a vehicle number in a vehicle number identification area corresponding to a parking area of ​​a parked vehicle set in the nearest driving lane, and the second vehicle number identification step can identify a vehicle number in an area comprising: a first adjacent identification area corresponding to a vehicle number identification area corresponding to a parking area of ​​a parked vehicle set in the nearest driving lane; and another second adjacent identification area adjacent to the first adjacent identification area.

[0184] In addition, according to one embodiment of the present invention, the second adjacent identification area may correspond to a vehicle number identification area located in a direction opposite to the driving direction of the vehicle in the adjacent driving lane, based on the first adjacent identification area.

[0186] Referring to FIG. 9, the second edge terminal sets an extended identification range in the adjacent driving lane in preparation for cases where identification in the nearest driving lane is difficult. Specifically, the area on the adjacent driving lane corresponding to parking area 1 can be subdivided into a first adjacent identification area (A3) and a second adjacent identification area (A4).

[0188] The first adjacent identification area is a vehicle number identification area within the adjacent driving lane corresponding to the parking area, and if the second edge terminal fails to identify the vehicle number in the vehicle number identification area within the closest driving lane, it can perform vehicle number identification in the first adjacent identification area.

[0190] The second adjacent identification area may correspond to the direction opposite to the driving direction of the parked vehicle (preferably the driving lane) based on the first adjacent identification area, that is, the area immediately before the vehicle enters the first adjacent identification area.

[0191] For example, due to the nature of on-street parking, vehicles frequently change lanes in advance or approach diagonally to enter the parking area; therefore, by additionally including the second adjacent identification area—which is the zone preceding the driving direction—in the analysis range, more video frames for license plate identification can be secured.

[0193] Referring to the example in Fig. 9, a vehicle with license plate number '1234' is moving from the adjacent driving lane to enter parking area 1. At this time, if the license plate number cannot be identified in the license plate identification area (A1) of the closest driving lane due to obscuration or interference by other driving vehicles, the second edge terminal expands the analysis range to the adjacent driving lane.

[0194] The second edge terminal can analyze together the first adjacent identification area (A3) within the vehicle-adjacent driving lane corresponding to parking area 1, and the second adjacent identification area (A4) located on the opposite side of the driving direction relative to the first adjacent identification area (A3) and not corresponding to parking area 1. In particular, as illustrated in FIG. 9, since the point at which a parked vehicle passes through area A4 is a section where the license plate is exposed relatively directly toward the camera lens, a clearer license plate image can be obtained than in area A3.

[0195] In other words, the second edge terminal can reduce the consumption of unnecessary computational resources by gradually expanding the search range for vehicle license plate identification, while minimizing recognition failures caused by obstructed visibility due to obstacles or steep entry angles.

[0197] According to one embodiment of the present invention, by operating a plurality of identification areas linked to the driving direction within the adjacent driving lane, the system can maximize reliability by providing continuous number identification opportunities from the time of approach to the time of entry.

[0199] FIG. 10 illustrates a process for determining normal parking of a vehicle through the calculation of a union area and an intersection area according to an embodiment of the present invention, and FIG. 11 illustrates a process for determining abnormal parking of a vehicle through the calculation of a union area and an intersection area according to an embodiment of the present invention.

[0200] According to one embodiment of the present invention, the step of deriving parking status information comprises: a step of calculating a union area by subtracting the overlapping area from the sum of the areas of the parking area and the parking vehicle in the first image when a parking vehicle is identified in the parking area in the first image; and a step of calculating an intersection area, which is the area where the parking area and the parking vehicle overlap in the first image; and if the area value obtained by subtracting the intersection area from the union area is greater than or equal to a preset standard, it can be determined that the parking vehicle is not properly parked in the parking area.

[0202] Referring to FIG. 10(a), in the parking state information derivation step (S1), the first edge terminal can identify a vehicle object that has entered the parking area through the first image. The memory of the first edge terminal may have an area corresponding to each parking area stored in advance, or may calculate an area corresponding to each parking area based on the first image, and may compare the bounding box or pixel mask area of ​​the parked vehicle object extracted from the image captured by the camera with the area of ​​the parking area in real time.

[0203] Through this, the first edge terminal can check whether the parked vehicle has landed accurately within the designated area or whether abnormal parking outside the normal parking range has occurred.

[0205] Specifically, referring to FIG. 10(b), the first edge terminal can calculate the union area, which is the size of the total outer area occupied by the two areas, by adding the area of ​​the parking area and the area of ​​the parked vehicle (preferably the area of ​​the bounding box or pixel mask of the parked vehicle) and then subtracting the area of ​​the part where the two areas overlap. Next, the intersection area, which is the size of the area where the parking area and the area of ​​the parked vehicle overlap on the first image, can be calculated.

[0206] Finally, the first edge terminal can calculate an area value by subtracting the intersection area from the previously calculated union area and compare it with a preset reference value to determine whether parking is normal.

[0207] In this case, the area value obtained by subtracting the intersection area from the corresponding union area has the same meaning as the sum of the area of ​​empty space not occupied by parked vehicles within the parking area and the area of ​​parked vehicles protruding beyond the boundary of the parking area, such as onto driving lanes.

[0209] When comparing Fig. 10 (b) and Fig. 11 (b) to examine the specific determination process, in the example of Fig. 10 (b), the parked vehicle is parked normally within the parking area in a manner that is almost identical to the guideline, so the difference between the union area and the intersection area is very small. That is, since the area, which is the sum of the empty space not occupied by the vehicle and the space protruding outside the area, is calculated to be less than the preset standard value, the road parking management system (1) determines this as a normal parking state.

[0210] On the other hand, referring to (a) and (b) of FIG. 11, it shows a situation where a parked vehicle is parked at an angle, significantly deviating from the boundary line of the parking area, and occupies only a part of the parking area. In this case, compared to the example in FIG. 10, the overlapping area between the parking area and the parked vehicle is drastically reduced, so the intersection area decreases, while the union area, which is the entire outline occupied by the two areas, increases significantly. Consequently, the area value obtained by subtracting the intersection area from the union area is calculated to be higher than a preset reference value, and the first edge terminal determines based on this that the parked vehicle has performed abnormal parking.

[0212] For example, in cases where a vehicle is parked by partially overlapping the parking area rather than fully entering it to avoid settling parking fees or to disrupt the system's detection, the area value calculated by subtracting the intersection area from the union area may be calculated as a very high value. Accordingly, if the area value exceeds a preset standard, the first edge terminal may perform the process of transmitting data flags indicating abnormal parking status within the parking status information to the second edge terminal and an external server. Upon receiving this, the server can provide the location of the parking area identified as abnormal parking and video information at that time to the manager terminal in the form of a real-time alarm, thereby supporting the manager in immediately assessing the situation on-site and taking prompt follow-up measures such as providing guidance on moving the vehicle, requesting towing, or imposing surcharges.

[0214] Through the configuration illustrated in FIGS. 10 and 11, the present invention can block attempts at illegal parking that are difficult to identify by simple location coordinate comparison alone. That is, the significance lies in preventing unnecessary fee disputes by ensuring fairness in parking management through area values, by proving the act of a vehicle intentionally parking across the boundary of a parking space to avoid detection by sensors.

[0216] FIG. 12 illustrates the process of deriving parking fee information for a parked vehicle by a server according to an embodiment of the present invention.

[0217] According to one embodiment of the present invention, the server may be configured to derive information regarding the parking fee for the parking vehicle based on the integrated information, the parking start time of the parking vehicle, and fee information for the parking area where the parking vehicle is parked.

[0219] Referring to FIG. 12, the server (2) can receive integrated information (parking area number, parking start time, vehicle number, etc.) transmitted in real time from the second edge terminal and record it in a database. The server (2) can calculate the total parking time by comparing the system's current time with the parking start time, and can automatically calculate the parking fee by applying a fee policy set for the corresponding parking area (e.g., 1,000 won per 10 minutes).

[0221] As shown in the example of FIG. 12, assuming the current time is 11:00, for a vehicle parked in parking area number 1 (vehicle number 1234), the parking start time included in the parking status information is 10:00. The server (2) subtracts the parking start time (10:00) from the current time (11:00) to derive a total parking time of 60 minutes. If the fee information for the area is 1,000 won per 10 minutes, the server (2) can calculate a parking fee of 6,000 won and display it on the administrator screen or record it as an unpaid fee for the vehicle.

[0222] For the vehicle parked in parking area number 2 (vehicle number 6789), the parking start time included in the parking status information is 10:30. Calculated in the same way, a total parking time of 30 minutes is derived based on the current time (11:00). When applying the fee policy (1,000 won per 10 minutes), the server (2) derives a parking fee of 3,000 won in real time.

[0224] The server (2) can perform functions such as providing real-time sales status to the administrator based on the derived fee information, or supporting users to prepay fees through a mobile app in the future.

[0226] FIG. 13 schematically illustrates the internal configuration of a computing device according to one embodiment of the present invention.

[0227] The roadside parking management system illustrated in FIG. 1 described above may include the components of the computing device (11000) illustrated in FIG. 13.

[0228] As illustrated in FIG. 13, the computing device (11000) may include at least one processor (11100), memory (11200), peripheral interface (11300), input / output subsystem (I / O subsystem) (11400), power circuit (11500), and communication circuit (11600). In this case, the computing device (11000) may correspond to the roadside parking management system illustrated in FIG. 1.

[0229] The memory (11200) may include, for example, high-speed random access memory, a magnetic disk, SRAM, DRAM, ROM, flash memory, or non-volatile memory. The memory (11200) may include software modules, instruction sets, or various other data required for the operation of the computing device (11000).

[0230] At this time, access to memory (11200) from other components, such as the processor (11100) or peripheral device interface (11300), can be controlled by the processor (11100).

[0231] The peripheral device interface (11300) can connect input and / or output peripheral devices of the computing device (11000) to the processor (11100) and memory (11200). The processor (11100) can perform various functions for the computing device (11000) and process data by executing software modules or instruction sets stored in the memory (11200).

[0232] The input / output subsystem can connect various input / output peripherals to the peripheral interface (11300). For example, the input / output subsystem may include a controller for connecting peripherals such as a monitor, keyboard, mouse, printer, or, if necessary, a touchscreen or sensor to the peripheral interface (11300). According to another aspect, input / output peripherals may be connected to the peripheral interface (11300) without passing through the input / output subsystem.

[0233] The power circuit (11500) can supply power to all or part of the components of the terminal. For example, the power circuit (11500) may include one or more power sources such as a power management system, a battery or alternating current (AC), a charging system, a power failure detection circuit, a power converter or inverter, a power status indicator, or any other components for power generation, management, and distribution.

[0234] The communication circuit (11600) can enable communication with another computing device using at least one external port.
