[0020] Hereinafter, a preferred embodiment of an intelligent parking lot management system according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0021] FIG. 1 is a block diagram schematically illustrating an intelligent parking lot management system according to an embodiment of the present invention, FIG. 2 is a block diagram illustrating the configuration of an intelligent parking lot management system according to an embodiment of FIG. 1, FIG. 3 is a block diagram illustrating the configuration of a parking monitoring camera of an intelligent parking lot management system according to FIG. 2, and FIG. 4 is an example diagram illustrating the operation process of an intelligent parking lot management system according to an embodiment of FIG. 1.

[0022] As shown in FIGS. 1 to 4, an intelligent parking lot management system according to one embodiment of the present invention may be composed of a parking lot management system unit (100) capable of providing optimal parking information and parking efficiency by analyzing parking spaces and vehicle entry and exit in a parking lot through artificial intelligence-based image analysis.

[0023] The parking lot management system unit (100) can extract empty parking spaces (210, 220) by analyzing an image of the parking lot (200).

[0024] Additionally, when the parking lot management system (100) detects an entry vehicle (300) entering the parking lot (200), it can generate and output parking location information for the extracted empty parking spaces (210, 220) and guidance information for the entry vehicle (300) to move to the empty parking spaces (210, 220).

[0025] To this end, the parking lot management system unit (100) may be configured to include an incoming vehicle recognition camera unit (110), a route guidance monitor (120), a parking monitoring camera unit (130), a control unit (140), a projector unit (150), and an outgoing vehicle recognition camera unit (160).

[0026] The vehicle entry recognition camera unit (110) is installed at the entrance of the parking lot (200) to photograph the front of a vehicle (300) entering the parking lot (200) and transmits the photographed image of the vehicle (300) to the control unit (140).

[0027] Additionally, the vehicle entry recognition camera unit (110) may additionally be provided with a display unit (not shown) that receives and displays license plate information of the vehicle entry (300) recognized by the control unit (140).

[0028] A route guidance monitor (120) is installed at the entrance of the parking lot (200) and at any location in the parking lot (200) so that parking location information of empty parking spaces (210, 220) output from the control unit (140) and guidance information for moving to empty parking spaces (210, 220) are displayed to the entering vehicle (300).

[0029] The parking monitoring camera unit (130) is configured to be installed in the parking lot (200) and to photograph the parking vehicles (310, 310a) and the entire parking space parked in the parking lot (200), and may be composed of a horizontal camera unit (131) that photographs the horizontal parking space and parked vehicles of the parking lot (200), and a vertical camera unit (132) that photographs the vertical parking space and parked vehicles.

[0030] The horizontal camera unit (131) may be composed of a first horizontal camera (131a), a second horizontal camera (131b) to an nth horizontal camera (131c) installed at regular intervals along the horizontal direction of the parking lot (200).

[0031] The vertical camera unit (132) may be composed of a first vertical camera (132a), a second vertical camera (132b) to an nth vertical camera (132c) installed at regular intervals along the vertical direction of the parking lot (200).

[0032] The control unit (140) can detect parked vehicles (310, 310a) and empty parking spaces (210, 220) within the parking lot (200) by analyzing a parking lot image captured by the parking monitoring camera unit (130) through an artificial intelligence-based analysis model.

[0033] Here, the AI-based analysis model learns to classify spaces where vehicles are parked and empty parking spaces in a parking lot from training data including images of a parking lot, images of empty parking spaces, and images of vehicles parked in parking spaces, using a deep learning model based on a Convolutional Neural Network (CNN).

[0034] Here, artificial intelligence-based analysis models can be seen as a type of analysis model created through a method called deep learning among machine learning.

[0035] Therefore, an artificial intelligence-based analysis model may also be used as a deep learning model or a deep learning analysis model.

[0036] Furthermore, machine learning is an application of artificial intelligence that enables complex systems to automatically learn and improve from experience without being explicitly programmed.

[0037] In addition, the accuracy and validity of machine learning models can partially depend on the data used to train them.

[0038] In addition, the AI-based analysis model may perform additional learning based on learning data, such as images of empty parking spaces and images of parked vehicles, additionally received by the control unit (140) from the parking monitoring camera (130).

[0039] In addition, the AI-based analysis model can improve the recognition rate of images captured in real-world environments by pre-training with additional images that have undergone various modifications to the original image, taking into account images that may be captured under various conditions such as lighting, shooting angle, camera shake, composition, photo resolution, rain, and snowfall.

[0040] Additionally, the control unit (140) can generate and store parking management information based on location information of empty parking spaces, such as parking space 1 (210) and parking space 2 (220), detected through an artificial intelligence-based analysis model.

[0041] Additionally, the control unit (140) may extract parking space display information 1 (211) and parking space display information 2 (221) corresponding to the location information of parking space 1 (210) and parking space 2 (220) detected through an artificial intelligence-based analysis model.

[0042] Additionally, the control unit (140) can extract a movement path from the entrance of the parking lot (200) to the detected empty parking space (210, 220) based on each location information.

[0043] Parking management information may include location information of empty parking spaces (210, 220) in a parking lot (200) where there are no parked vehicles (310, 310a), location information of the parking floor (e.g., basement 1st floor, basement 2nd floor, etc.) where the parking space (210, 220) is located, and travel path information to the parking space (210, 220).

[0044] Additionally, the control unit (140) can detect an incoming vehicle (300) entering the parking lot (200) by analyzing a vehicle image captured through the incoming vehicle recognition camera unit (110), and can recognize the license plate information of the detected incoming vehicle (300).

[0045] Additionally, the control unit (140) can generate location information of empty parking spaces (210, 220) based on parking management information and guidance information for moving to the corresponding parking space and output it through a path guidance monitor (120) or a projector unit (150).

[0046] In addition, the control unit (140) may select and provide an optimal parking space based on recognition information of the entering vehicle (300).

[0047] The control unit (140) may select and provide the nearest location information among the empty parking spaces by comparing the recognition information of the entering vehicle (300) with pre-stored vehicle-related information, for example, in the case of an apartment, the building / unit number of the registered vehicle.

[0048] Additionally, the control unit (140) may compare the information of the recognized incoming vehicle (300) with pre-stored vehicle-related information, and if it is determined to be an electric vehicle, it may extract and provide location information around the electric vehicle charger.

[0049] Additionally, the control unit (140) may analyze the parking pattern of the incoming vehicle (300) through an artificial intelligence-based analysis model based on recognition information of the incoming vehicle (300), for example, the parking pattern related to the location where the incoming vehicle (300) is parked when there are many empty parking spaces, and may extract and provide optimal parking location information according to the analyzed parking pattern.

[0050] In addition, the control unit (140) can analyze the usage frequency and usage time of the parking lot (200) through the artificial intelligence-based analysis model based on information related to the entering vehicle (300) and manage it by reflecting it in the parking management information for the entering vehicle (300).

[0051] Additionally, the control unit (140) can analyze the image of the exiting vehicle received through the exiting vehicle recognition camera (160) to recognize the license plate information of the exiting vehicle (320) and calculate and manage parking-related information of the exiting vehicle (320), such as parking location and parking time.

[0052] Additionally, the control unit (140) can analyze an image captured by the parking monitoring camera (130) to determine whether the entering vehicle (300) has been parked in the guided parking space (210, 220) or another parking space, detect parking location information, and match the parking vehicle with the parking location to reflect it in the parking management information for management.

[0053] Additionally, when a new parking space is detected during the process of guiding to a parking space (210, 220), the control unit (140) may guide to the new parking space by reflecting the detected parking space in real time.

[0054] Additionally, the control unit (140) can analyze the current parking status and accumulated parking management information to calculate information related to the fullness rate of the parking lot (200) and transmit the calculated information to the manager terminal (400).

[0055] Additionally, the control unit (140) can analyze the parking time of the parked vehicle (310, 310a) to determine whether it is in a state of not being operated for a long period of time, and generate parking management information based on long-term parking and transmit it to the manager terminal (400).

[0056] The projector unit (150) is installed in the parking lot (200) and operates to display location information of empty parking spaces (210, 220) output from the control unit (140) and a path guidance display (151) for moving to the corresponding parking space on the floor of the parking lot (200), thereby allowing the entering vehicle (300) to move along the path guidance display (151) displayed on the floor.

[0057] The exit vehicle recognition camera unit (160) is installed at the exit of the parking lot (200) to photograph the exit vehicle (320) exiting the parking lot (200), and the image of the photographed exit vehicle (320) can be transmitted to the control unit (140).

[0058] The administrator terminal (400) connects to the parking lot management system unit (100) via a network, receives parking management information from the parking lot management system unit (100), calculates statistical information including period-based statistical information of the parking lot (200) and vehicle-based entry and exit information, and can convert and output the calculated statistical information according to an arbitrary format.

[0059] A parking location guidance terminal (500) is installed in a parking lot (200) or any location, and when a parking location guidance request, for example, a vehicle number, is entered by a user, it can retrieve location information of the vehicle from a parking lot management system (100) connected via a network and display it so that the user can check it.

[0060] Therefore, through AI-based video analysis, optimal parking information and parking efficiency can be provided by analyzing parking spaces and the entry and exit of vehicles in the parking lot.
