Description

Technology Field

[0001] The present invention relates to a vehicle inflow analysis system, and more specifically, to a vehicle inflow analysis system capable of efficiently processing information on the entry and exit of vehicles. Background Technology

[0003] In order to minimize traffic congestion and induce rational traffic flow in a road network built within a limited spatial area, it is necessary to collect and analyze traffic information.

[0004] Such traffic information is collected and analyzed in real time and can be utilized to control traffic signals within the road network in real time, or for traffic management and control by administrative personnel. Furthermore, the collection and analysis of traffic data over a specific period can facilitate the reconstruction of the road network and the reorganization of the signal system.

[0005] Accordingly, various technologies for the collection and analysis of traffic information have been developed and are being used. In this regard, Korean Registered Patent Publication No. 10-1995813, "Image-based traffic information provision system and method," and No. 10-1297321, "Traffic volume survey equipment having a traffic information collection function," have been disclosed.

[0006] However, conventional traffic information collection and analysis technologies had the disadvantage that, as information was collected and analyzed only in terms of basic traffic volume or vehicle type data, it was impossible to generate derivative traffic information tailored to various analysis situations arising from real-world road conditions or the construction or modification of buildings and infrastructure.

[0007] Furthermore, with the recent advancement of mobile communication technology, various value-added services are being provided, including not only basic communication services but also transportation-related services.

[0008] Currently, a representative method for acquiring road traffic information is generally used, which involves installing measuring devices such as CCTVs (Closed Circuit Televisions) around roads to measure the location and speed of vehicles.

[0009] In addition, other methods for obtaining road traffic information include obtaining road traffic information by measuring the speed of vehicles using speed measuring devices installed on the road, or obtaining road traffic information by measuring the speed of vehicles on the road using loop detectors installed on the road.

[0010] However, since this method requires installing a specific measuring instrument on every road under surveillance, it incurs significant equipment costs and management personnel, making it practically difficult to obtain traffic information for all road sections nationwide.

[0011] To address the aforementioned problems, a method for obtaining road traffic information using mobile communication networks has recently been provided.

[0012] For example, a mobile terminal equipped with a built-in GPS (Global Positioning System) receiver can decode a GPS signal received in real time, acquire GPS data from the decoded signal, and provide the acquired GPS data to a server that provides a specific traffic information service through a mobile communication network.

[0013] The traffic information providing server can obtain specific traffic information through the analysis of received GPS data and provide the obtained traffic information to the mobile terminal via a mobile communication network.

[0014] However, the method of providing traffic information using GPS receivers faced some difficulties in activating the service because the number of mobile terminals equipped with built-in GPS receivers was limited.

[0015] Another conventional method for providing road traffic information was a method for providing road traffic information characterized by analyzing road traffic information of the area where the mobile terminal is located using charging data (CDR: Charging Data Record) of a mobile terminal whose call has ended in a mobile communication network (Korean Published Patent No. 2005-0100121, Korean Published Patent No. 2007-0006386). That is, the above method can calculate the movement speed of the mobile terminal by using the location information of the first connected base station and the base station connected at the end of the call, and the time information of the connection to the base station, which are included in the charging data of a specific mobile terminal.

[0016] In addition, the above-described method can calculate the route and travel speed of each road section through periodic location estimation of the mobile terminal as an auxiliary means.

[0017] However, the method of obtaining traffic information using the aforementioned billing data has a problem in that traffic information cannot be obtained in areas where no call is set, that is, areas where call data does not exist, because billing data can only be obtained when a call is set on the mobile terminal. Therefore, there was an urgent need for the development of technology regarding a vehicle inflow analysis system that can resolve the above problem. The problem to be solved

[0019] The present invention is designed to solve the above-mentioned problems and aims to provide a vehicle inflow analysis system capable of efficiently processing vehicle inflow and outflow information. means of solving the problem

[0022] Here, the above-mentioned vehicle information may include one or more pieces of information among CCTV number, time of occurrence, location name, region name, vehicle number, duration of stay, and movement path.

[0023] In addition, the aforementioned related agency databases may include the Tax Department database, the National Police Agency database, the Ministry of Environment database, and the Korea Environment Corporation database.

[0024] In addition, the vehicle inflow analysis system according to an embodiment of the present invention may further include an external environment analysis unit that collects one or more external environment information among weather, event information, stock price information, and oil price information.

[0025] In addition, the above analysis unit can preprocess the collected data using a Hadoop-based analysis module that processes the data in a distributed manner.

[0026] In addition, the vehicle inflow analysis system according to an embodiment of the present invention further includes a manager server that views collected, extracted, statistical, analyzed, and stored information linked with a data collection unit, a data input unit, an analysis unit, and a problem vehicle recognition unit of the vehicle inflow analysis system, and the manager server can graph and quantify the information transmitted from the data collection unit, the data input unit, the analysis unit, and the problem vehicle recognition unit to display it.

In describing the present invention, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0039] Hereinafter, a vehicle inflow analysis system (1) according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

[0041] First, FIG. 1 is a configuration diagram of a vehicle inflow analysis system according to an embodiment of the present invention, FIG. 2 is a block diagram of a data collection unit, FIG. 3 is a block diagram of an analysis unit, FIG. 4 is a block diagram of an external environment analysis unit, and FIG. 5 is a block diagram of a related organization database.

[0042] Referring to FIGS. 1 to 5, a vehicle inflow analysis system (1) according to an embodiment of the present invention may include a data collection unit (100), a data input unit (200), an analysis unit (300), and a problem vehicle recognition unit (400).

[0043] First, the data collection unit (100) can collect data regarding images or video of vehicles entering and exiting from at least one CCTV (Closed Circuit Television) (110).

[0044] Specifically, the data collection unit (100) can collect shooting data regarding images or videos from a plurality of CCTVs (110) installed on the road, and at this time, inside the CCTV (110), a GPS module (111) in which location information of the CCTV (110) is recorded and a control module (112) that controls the pixels, quality, and degree of enlargement and reduction of images and videos of vehicles entering and exiting may be installed.

[0045] Additionally, a recording module (113) for storing collected image or video data may be installed inside the CCTV (110), and the recording module (113) may transmit data related to the image or video stored to the data input unit (200), analysis unit (300), and problem vehicle recognition unit (400) described later.

[0046] Meanwhile, the data collection unit (100) is disclosed in the form of a CCTV (110), which is the most desirable form for effectively extracting data of vehicles traveling on the road, but this is not necessarily limited to any video collection device capable of collecting video or images, such as a personal black box or camcorder installed in a vehicle.

[0047] Additionally, the above CCTV (110) may be constructed to be arranged horizontally and vertically along the length of the road for the extraction of more accurate image and video information, and at this time, the above CCTV (110) may be spaced apart from each other at a certain interval, and may be configured to be adjustable in angle based on a connecting part fixed and installed on the roadside.

[0048] To this end, the CCTV (110) may include a rotary motor or an axis motor provided at the bottom of the CCTV (110) to control the angle and shooting radius of the CCTV (110), but this is only a preferred embodiment and may include any mechanical means capable of varying and changing the angle of the CCTV (110).

[0049] Through this, the data collection unit (100) according to the embodiment of the present invention has the advantage of improving the accuracy of the object recognition rate by collecting images and videos from various viewpoints using a plurality of CCTVs (110) and detecting an object, i.e., a vehicle, from multiple angles, which may be identified as only one scene.

[0050] In summary, the vehicle inflow analysis system (1) according to an embodiment of the present invention has the advantage of being able to interpret object images more precisely based on video or images input through a plurality of CCTVs (110).

[0051] In addition, the data input unit (200) can extract incoming and outgoing vehicle information from the image collected through the data collection unit (100).

[0052] Here, the vehicle entry / exit information may include one or more pieces of information among CCTV number, time of occurrence, location name, region name, vehicle number, vehicle speed, duration of stay, and movement path.

[0053] More specifically, the above CCTV information may refer to information of software built into the CCTV (110), and the location name may literally refer to the installation location of the CCTV (110).

[0054] That is, it refers to the location information of the CCTV (110) extracted through the GPS module (111) built inside the CCTV (110).

[0055] Additionally, the regional name refers to the area where the CCTV (110) is installed in the same manner as the above-mentioned installation location, and the information regarding the time of occurrence is the time information of the image or video in which a vehicle entering or exiting the location of the CCTV (110) is recorded, and the vehicle information may refer to the vehicle number, direction of travel, and speed of the vehicle collected through the CCTV (110).

[0056] However, the aforementioned vehicle entry and exit information is a type of data used to determine the status of vehicles entering or exiting, and is not necessarily limited to the specified range.

[0057] In addition, based on the image or video of the vehicle, the method for object detection in vehicle data may be configured based on the RefineDet program used to detect objects present in the collected video.

[0058] More specifically, the RefineDet program can be configured through a combination of ARM (Anchor refine module) and ODM (Object detection module) modules. First, the ARM can perform the role of boxing objects present in video or images collected through the CCTV (110) and adjusting the positions of these boxes.

[0059] In addition, the above ODM is a module that extracts features necessary for object detection within an input area through the above ARM, learns an offset for each pixel position included within the input area, and can extract features necessary for object detection within a dynamic input area to which the offset is applied.

[0060] However, the object extraction method using the RefineDet program described above is merely one type of object extraction method used to operate the present invention and is not necessarily limited to any interpretation and computation extraction program used to extract regions of interest and data based on vehicle image data.

[0061] In addition, the analysis unit (300) can statistically analyze and store the status of vehicle entry and exit by specific location using the vehicle entry and exit information, and generate vehicle entry and exit status data by specific location.

[0062] To this end, the analysis unit (300) can preprocess and process the collected data using a Hadoop module-based data analysis module that processes the collected data in a distributed manner. For example, information related to vehicles, location names, region names, etc., can be processed by distributing it to the first analysis module (310), and information regarding vehicle traffic volume and the number of vehicles entering and exiting can be processed by distributing it to the second analysis module (320).

[0063] Through this, the vehicle inflow analysis system (1) according to the embodiment of the present invention has the advantage of reducing the burden on the analysis unit (300) and reducing errors that occur during the calculation process due to data overload by distributing the processed data through multiple analysis modules (310, 320) rather than a single analysis module.

[0064] Additionally, the problem vehicle recognition unit (400) can determine whether a vehicle is a problem vehicle by matching the extracted inflow / outflow vehicle information with the relevant agency database (500), and the relevant agency database (500) may include the tax department database (510), the police department database (520), the Ministry of Environment database (530), and the Korea Environment Corporation database (540).

[0065] Specifically, the above-mentioned related agency database (500) is linked with the previously described data collection unit (100), data input unit (200), and analysis unit (300), and based on vehicle data collected, analyzed, and stored through each device, namely vehicle number and image data, it searches and analyzes data such as whether the owner of the vehicle clearly exists (search for stolen vehicles), whether there are unpaid fees (tolls, taxes, and insurance premiums), and whether the vehicle has undergone inspection, and can be operated to send MMS text messages or mail to a stored address to a personal terminal owned by the vehicle owner through a related agency terminal linked to the related agency database (500).

[0066] Through this, the vehicle inflow analysis system (1) according to the embodiment of the present invention is linked with a related agency database (500) and has the advantage of being able to efficiently manage problematic vehicles and owners based on data of passing vehicles.

[0067] Meanwhile, the data collection unit (100), data input unit (200), analysis unit (300), and problem vehicle recognition unit (400) described above may preferably use a wireless communication network such as wireless LAN, Bluetooth, or Wi-Fi, but this is merely a preferred embodiment and may include all means for communication between the data collection unit (100), data input unit (200), analysis unit (300), and problem vehicle recognition unit (400), and in situations where wireless communication is restricted, communication may be performed via wired connection.

[0068] In addition, the vehicle inflow analysis system (1) according to an embodiment of the present invention may further include an external environment analysis unit (330) that collects one or more external environment information among weather, stock price information, oil price information, and event information.

[0069] Specifically, the external environment analysis unit (330) may include or be linked to a weather information system (331), a stock price / oil price information system (332), and an event information system (333).

[0070] First, the weather information system (331) can receive current or near-future weather data from the weather information system of the Korea Meteorological Administration, derive weather information based on the field conditions, and transmit it to the data input unit (200) and the analysis unit (300).

[0071] In addition, the above stock price / oil price information system (332) can receive data related to stock prices or oil prices from a bank’s API system showing market economic conditions or from a server and system of an institution related to stock prices and oil prices, and derive the estimated consumption cost according to the vehicle’s entry / exit or expected route.

[0072] In addition, the above event information system (333) can predict road traffic conditions (congestion) by receiving information regarding schedules and dates related to events held in each region from the servers and systems of each local government, and the above event information system (333) can be linked with a Road Traffic Authority system that stores road traffic condition information.

[0073] Meanwhile, the information derived from the external environment analysis unit (330) can be transmitted and stored in the input unit (200) and the analysis unit (300), and the analysis unit (300) that receives such data can data mine the information (weather, stock price information and oil price information, event information) of the stored external environment analysis unit (330).

[0074] Here, data mining is defined as “finding valuable and useful information from a mountain of numerous data,” and techniques for performing data mining according to embodiments of the present invention may include all of the following: OLAP, cluster analysis, linkage analysis, case-based reasoning, association rule discovery, artificial neural networks, decision trees, and genetic algorithms.

[0075] At this time, the information of the external environment analysis unit (330) stored in the analysis unit (300) can be stored together with vehicle information, and if information of a vehicle similar to the stored vehicle information is stored, the information of the external environment analysis unit (330) that was previously stored and the information of the data input unit (200) that will be stored later can be compared, and the average of these values ​​can be transmitted to the analysis unit (300).

[0076] Through this, average information regarding a specific region or vehicle stored in the analysis unit (300) can be viewed, thereby allowing for easy identification of the average price, average traffic conditions, and average weather regarding the specific region, and has the advantage of reducing the time loss consumed in data processing.

[0077] In addition, the vehicle inflow analysis system (1) according to an embodiment of the present invention may further include an administrator server (600) that views collected, extracted, statistical, analyzed, and stored information by linking with the data collection unit (100), data input unit (200), analysis unit (300), and problem vehicle recognition unit (400) of the vehicle inflow analysis system (1).

[0078] At this time, the administrator server (600) can display information transmitted from the data collection unit (100), data input unit (200), analysis unit and problem vehicle recognition unit (400) by graphing and quantifying it.

[0079] In addition, the above-mentioned administrator server (600) is linked with a recording module (113) built within the above-mentioned CCTV (110), thereby allowing the administrator to freely view recorded images and videos stored through the CCTV (110) and to control the operation of the rotary motor and shaft motor.

[0080] Meanwhile, the vehicle inflow analysis system (1) may further include a manager terminal (610) linked to the manager server (600), and the manager terminal (610) may be provided in the form of a PDA or smartphone that is convenient for the manager to operate directly by hand, while performing the same role as the manager server (600).

[0081] In addition, the above-mentioned administrator terminal (610) is linked with a GPS module (111) built within the above-mentioned CCTV (110) to receive information regarding the location of the CCTV (110).

[0082] This is to transmit the location of the site where the CCTV (110) is located to the manager who manages the CCTV (110).

[0083] Meanwhile, the location information of the CCTV transmitted to the administrator terminal (610) through the above GPS module (111) is linked with a GPS independently provided in the administrator terminal (610), so that information that can be derived from the location, such as information regarding the distance between the administrator terminal (610) and the CCTV (110), the way to get there, and the time required for travel, can be displayed on the administrator terminal (610).

[0084] Thus, the manager who owns the manager terminal (610) has the advantage of being able to continuously manage and supervise by receiving location information regarding the CCTV (110) and information about vehicles passing through the CCTV (110) under management at any time, even in situations where it is difficult for the manager to operate it directly.

[0086] The vehicle inflow analysis system (1) according to the embodiment of the present invention described above with reference to FIGS. 1 to 5 is not implemented only through a device and / or method, but may also be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded, etc., and such implementation can be easily implemented by a person skilled in the art to which the present invention belongs from the description of the embodiment described above.
