Description

  The present invention relates to a data generation system, a data generation device, a data generation method, and a data generation program that generate data for analysis related to the use of a parking lot.

  A technique of installing a camera in a parking lot or the like and recognizing a car number from a photographed vehicle image is known as a conventional technique (see Patent Document 1).

JP 2007-188197 A

  However, the prior art only uses the vehicle number as an identifier for identifying the vehicle, and has not been able to analyze the use of the parking lot based on the vehicle number. As an analysis based on the vehicle number, there may be a method of using the name of the land transportation branch office described in the vehicle number. However, in the case of Shonan, for example, it is added to vehicles registered in Hiratsuka, Fujisawa, Odawara, Chigasaki, Chino, Isesaki, Minamiashigara, Takaza-gun, Naka-gun, Ashigarashiga-gun, Ashigarashimo-gun. Has been. Therefore, for example, the name of the land transportation branch office is too rough to analyze from which region the parking lot users such as commercial facilities come from.

  Recently, when a car number information is transmitted, a paid service that returns a part of automobile inspection registration information (information that cannot be specified by an individual) (reference 1: vehicle inspection registration information providing service: [November 27, 2013] Day search], the Internet <URL: https: //www.e-airis.jp/teikyou/TeikyouServlet? __Next = FA0101 & __ route = FA01>) is also provided. Can be obtained. In the present specification, information on the name of the town and the vehicle type in which the vehicle is registered is referred to as “vehicle inspection registration information”, and a device that outputs vehicle inspection registration information when a vehicle number is input is referred to as a “registered data management device”. However, the “vehicle inspection registration information” and the “registration data management device” are not limited to the information provided by the service of Reference Document 1 and the device for providing it.

  However, since the camera installed in the parking lot must be a cheaper camera than the camera installed on the expressway due to the budget and the like, the probability that the vehicle number can be accurately recognized is low. In addition, since the vehicle inspection registration information providing service requires a cost according to the number of inquired vehicle numbers, inquiries to a vehicle number that cannot be accurately recognized require a wasteful cost.

  Therefore, the present invention aims to efficiently generate data that can be used for analysis related to the use of a parking lot, on the assumption that the vehicle number acquired using a camera installed in the parking lot is not necessarily accurately recognized. And

  The data generation system of the present invention includes an on-site device and a data generation device, and generates data for analysis related to the use of a parking lot. The on-site device includes two cameras, a vehicle number recognition unit, a vehicle number information generation unit, and a vehicle number information recording unit. The first camera is installed at the entrance of the parking lot and obtains the incoming vehicle image. The second camera is installed at the exit of the parking lot, and acquires a leaving vehicle image. The vehicle number recognition unit recognizes the vehicle number from the incoming vehicle image and the outgoing vehicle image, and outputs the error information indicating an error if the vehicle number can be recognized, and if not recognized. A vehicle number information generation part acquires the warehousing vehicle number information which matched the vehicle number or error information which the vehicle number recognition part output for every warehousing video, and the information of the date and time when the said warehousing image | video was acquired. In addition, the car number information generation unit obtains the car number information that associates the car number or error information output by the car number recognition unit with the information of the date and time when the car vehicle information was obtained for each car image. To do. The vehicle number information recording unit records the incoming vehicle number information and the outgoing vehicle number information.

  The data generation device includes a comparison unit, a conversion unit, a vehicle inspection registration information acquisition unit, and a recording unit. The comparison unit receives a plurality of warehousing vehicle number information and a plurality of evacuation vehicle number information that satisfy a predetermined comparison condition. Then, if the vehicle number is the same, and there is warehousing vehicle number information and evacuation vehicle number information that do not cause a contradiction in date and time, the comparison unit associates the warehousing vehicle number information with the delivery vehicle number information. An inquiry list including the vehicle number is generated. The conversion unit converts the vehicle number information in the inquiry list into a predetermined format. The vehicle inspection registration information acquisition unit acquires vehicle inspection registration information for each vehicle number in the inquiry list, and associates the vehicle inspection registration information with the incoming vehicle number information and the outgoing vehicle number information corresponding to the vehicle number. The recording unit records the incoming vehicle number information, the outgoing vehicle number information, and the vehicle inspection registration information.

  When analyzing the use of parking lots, the total number is important, such as the number of vehicles entering and leaving each time zone, and the ratio is not the total number, such as the percentage of visitors by area and the ratio by car type. There is an important analysis. The vehicle number information is not important in the analysis of the total number, and the vehicle inspection registration information obtained from the vehicle numbers is important in the analysis of the ratio.

  According to the data generation system of the present invention, the incoming car number information and the outgoing car number information can be acquired as information relating to the total number of vehicles. And even if the vehicle number information that has not been correctly recognized is included in the incoming vehicle number information and the outgoing vehicle number information, only the vehicle numbers that are highly likely to be recognized accurately are extracted while comparing the two. Get vehicle inspection registration information. Therefore, it is possible to obtain vehicle inspection registration information for a vehicle number that is highly likely to be recognized correctly. Therefore, the information regarding the total number and the information regarding the ratio, which are useful for the analysis regarding the use of the parking lot, can be generated.

  Hereinafter, embodiments of the present invention will be described in detail. In addition, the same number is attached | subjected to the structure part which has the same function, and duplication description is abbreviate | omitted.

  FIG. 1 shows an outline of the data generation system of the present invention, FIG. 2 shows an example of a functional configuration of the data generation system of the present invention, and FIG. 3 shows an example of a processing flow of the data generation system of the present invention. The data generation system 10 of the present invention includes an on-site device 200 and a data generation device 100 connected via a network 500, and generates data for analysis related to the use of the parking lot 900. There may be a plurality of parking lots. Further, the operation terminal 300 and the registered data management device 800 may be connected to the network 500. The operation terminal 300 performs operations related to the operation of the on-site device 200 and the data generation device 100, the use of the parking lot 900 using the data generated by the data generation device 100, and the like. Note that there may be a plurality of operation terminals 300, and processing that can be performed for each operation terminal 300 may be different. The registration data management device 800 is, for example, a device for providing an automobile inspection registration information providing service in Reference Document 1. When vehicle number information is input in a predetermined format, a vehicle corresponding to the vehicle number is registered. The vehicle inspection registration information which is the information of the town name and vehicle type is output. A plurality of registered data management devices 800 may exist as long as the inquiry destination can be distinguished from the vehicle number. For example, there may be two registration data management devices that output vehicle inspection registration information of ordinary vehicles and a registration data management device that outputs vehicle inspection registration information of light vehicles.

  The on-site device 200 includes two cameras 210 and 220 and a management terminal 230. The management terminal 230 includes at least a vehicle number recognition unit 240, a vehicle number information generation unit 250, and a vehicle number information recording unit 290. The management terminal 230 may be realized by installing software on a computer such as a personal computer. The camera 210 is installed at the entrance 910 of the parking lot 900 and acquires an incoming vehicle image. The camera 220 is installed at the exit 920 of the parking lot 900 and acquires a leaving vehicle image. The vehicle number recognition unit 240 recognizes the vehicle number from the incoming vehicle image and the outgoing vehicle image, and outputs error information indicating an error if the vehicle number can be recognized, and indicates an error if the vehicle number cannot be recognized (S240).

  The vehicle number information generation unit 250 acquires warehousing vehicle number information that associates the vehicle number or error information output by the vehicle number recognition unit 240 with the information of the date and time when the warehousing image is acquired for each warehousing image. To do. In addition, the car number information generating unit 250 outputs car number information that associates the car number or error information output by the car number recognition unit 240 with the information of the date and time when the car vehicle information was acquired for each car image. Is acquired (S250). The vehicle number information recording unit 290 records warehousing vehicle number information and outgoing vehicle number information. FIG. 4 shows an example of warehousing car number information, and FIG. 5 shows an example of warehousing car number information. At the stage recorded in the vehicle number information recording unit 290, the incoming vehicle number information and the outgoing vehicle number information are not associated with each other. In this example, the vehicle entered on January 4, 2013 and the vehicle exited are shown, but other date data are also included in the entry car number information and the exit car number information. N is the total number of vehicles received on January 4, 2013, and is the total number of vehicle number information received on that day. M is the total number of vehicles issued on January 4, 2013, and is the total number of the vehicle number information for that sunrise. Since there may be a vehicle parked at night, N = M is not always satisfied.

  The data generation device 100 includes a comparison unit 110, a conversion unit 120, an automobile inspection registration information acquisition unit 130, and a recording unit 190. The comparison unit 110 inputs a plurality of warehousing vehicle number information and a plurality of evacuation vehicle number information that satisfy a predetermined comparison condition. The “predetermined comparison condition” may be a condition with a high probability that the entered vehicle will leave. For example, in the case of a commercial facility where there are few vehicles parked at night, the comparison condition may be a range of the same day of entering and leaving. Moreover, in the case of an accommodation facility where most vehicles park at night, the date of entry and departure may be shifted and used as a comparison condition. When the vehicle number is the same and there is warehousing vehicle number information and evacuation vehicle number information that do not cause a contradiction in date and time, the comparison unit 110 displays the warehousing vehicle number information and the evacuation vehicle number information. An inquiry list including the vehicle number is generated (S110). “No date / time contradiction” means to exclude the date and time that is not possible, such as when the shipping time is earlier than the warehousing time. That's fine. 6 and 7 show examples of warehousing vehicle number information and evacuation vehicle number information associated with each other. FIG. 8 shows an example of an inquiry list. In these examples, the vehicle entered on January 4, 2013 and the vehicle delivered on January 4, 2013 are defined as comparison conditions, and the entry vehicle number information in FIG. 4 and the exit vehicle number information in FIG. It is the result of comparison. K is the number of the incoming car number information and the outgoing car number information (the incoming time is before the outgoing time) where the vehicle numbers are the same and the date and time do not contradict each other, and K ≦ N and K ≦ M It is an integer. Since the inquiry list is created by comparing the entering car number information and the leaving car number information, the probability that the car number is correct can be significantly increased.

  However, in actual equipment, it is also assumed that the entry car number information or the exit car number information cannot be obtained because the camera 210 or the camera 220 is out of order. For such a case, it is possible to create an inquiry list from only one of the obtained information (incoming car number information or outgoing car number information) without comparing the incoming car number information and the outgoing car number information. You may leave it.

  The conversion unit 120 converts the vehicle number information in the inquiry list into a predetermined format (S120). The “predetermined format” is a format that satisfies the conditions for input to the registered data management device 800. When there are a plurality of registered data management devices 800, the information on the car numbers in the inquiry list may be divided for each registered data management device to be inquired, and then converted into a predetermined format for each registered data management device. For example, when the registration data management device is different between a normal car and a light car, it is only necessary to distinguish between a normal car and a light car from the car number and convert them into respective formats. The conversion unit 120 further sends vehicle number information in a predetermined format to the registered data management device 800 via the network 500, and the vehicle inspection registration information (information on the name of the town and the vehicle type in which the vehicle corresponding to the vehicle number is registered). ). The registration data management device 800 collates the vehicle number information and sends vehicle inspection registration information to the data generation device 100 (S800). Note that transmission of car number information in a predetermined format to the registered data management device 800 may be performed automatically by the conversion unit 120 or in accordance with an instruction from the operation terminal 300. Information may be exchanged with the registered data management device 800 by manually delivering a recording medium on which information is recorded.

  The vehicle inspection registration information acquisition unit 130 acquires vehicle inspection registration information for each vehicle number in the inquiry list, and associates the vehicle inspection registration information with the incoming vehicle number information and the outgoing vehicle number information corresponding to the vehicle number (S130). The vehicle inspection registration information may be acquired from the registration data management apparatus 800 via the network 500 or may be acquired via a recording medium. The recording unit 190 records incoming vehicle number information, outgoing vehicle number information, and vehicle inspection registration information. FIG. 9 shows an example of the vehicle inspection registration information. The vehicle inspection registration information is arranged in the order of the inquiry list in FIG. Moreover, since the warehousing number and the warehousing number are also described, it turns out that it is matched with the warehousing vehicle number information and the evacuation vehicle number information. FIG. 10 is an example of warehousing vehicle number information, and FIG. 11 is an example of evacuation vehicle number information. In this way, the vehicle inspection registration information may be added to the incoming vehicle number information and the outgoing vehicle number information.

  When analyzing the use of parking lots, the total number is important, such as the number of vehicles entering and leaving each time zone, and the ratio is not the total number, such as the percentage of visitors by area and the ratio by car type. There is an important analysis. The vehicle number information is not important in the analysis of the total number, and the vehicle inspection registration information obtained from the vehicle numbers is important in the analysis of the ratio. For example, the operation terminal 300 may analyze the percentage of visitors in units of town names, and display the percentage of visitors on a map in different colors. It is also possible to analyze changes in the distribution of visitors on weekdays and weekends. If such an analysis is performed, leaflets of commercial facilities visited by users of the parking lot can be distributed efficiently. In other words, various analyzes regarding marketing are possible.

  According to the data generation system of the first embodiment, warehousing vehicle number information and leaving vehicle number information can be acquired as information relating to the total number of vehicles. And even if the vehicle number information that has not been correctly recognized is included in the incoming vehicle number information and the outgoing vehicle number information, only the vehicle numbers that are highly likely to be recognized accurately are extracted while comparing the two. Get vehicle inspection registration information. Therefore, it is possible to obtain vehicle inspection registration information for a vehicle number that is highly likely to be recognized correctly. Therefore, the information regarding the total number and the information regarding the ratio necessary for the analysis regarding the use of the parking lot can be generated.

[Modification 1]
The data generation device 100 may further include a warehousing counting unit 140 and a warehousing counting unit 150. The warehousing counting unit 140 obtains the total number of warehousing vehicle number information and the number of warehousing vehicle number information corresponding to the vehicle inspection registration information for warehousing vehicle number information satisfying a predetermined warehousing date and time, and the total number of warehousing vehicle number information The recognition rate at the time of warehousing which is the ratio of the number of warehousing vehicle number information to which the vehicle inspection registration information corresponds is obtained (S140). The delivery counting unit 150, for delivery vehicle number information that satisfies a predetermined delivery date and time, the total number of delivery vehicle number information, the number of delivery vehicle number information corresponding to the vehicle inspection registration information, and the vehicle inspection for the total number of delivery vehicle number information. The recognition rate at the time of delivery which is a ratio of the number of the delivery vehicle number information with which registration information respond | corresponds is calculated | required (S150). The “predetermined warehousing date and time condition” and “predetermined warehousing date and time condition” mean the conditions of the date and time to be analyzed, for example, “Sunday in March”. In the examples of FIGS. 6, 7 and 8, the total number of warehousing car number information is N, the number of warehousing car number information corresponding to the vehicle inspection registration information is K, the recognition rate at the time of warehousing is K / N, The total number is M, the number of outgoing vehicle number information corresponding to the vehicle inspection registration information is K, and the outgoing recognition rate is K / M.

Thus, if the recognition rate at the time of entering or the recognition rate at the time of leaving is obtained, it is easy to predict the total number of vehicles coming from A town from the number of vehicles in A town included in the vehicle inspection registration information. For example, when the number of vehicles in A town included in the vehicle inspection registration information is K _A and the recognition rate at the time of warehousing is R _I , the total number of vehicles coming from A town may be predicted as K _A / R _I. Further, an average of the receipts upon recognition rate R _I and unloading time of recognition rate R _O may be used in place of R _I. As described above, it is possible to analyze the use of the parking lot more efficiently than the data generation system of the first embodiment.

[Program, recording medium]
The various processes described above are not only executed in time series according to the description, but may also be executed in parallel or individually as required by the processing capability of the apparatus that executes the processes. Needless to say, other modifications are possible without departing from the spirit of the present invention.

  Further, when the above-described configuration is realized by a computer, processing contents of functions that each device should have are described by a program. The processing functions are realized on the computer by executing the program on the computer.

  The program describing the processing contents can be recorded on a computer-readable recording medium. As the computer-readable recording medium, for example, any recording medium such as a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory may be used.

Furthermore, the program may be distributed by storing the program in a storage device of the server computer and transferring the program from the server computer to another computer via a network.

  A computer that executes such a program first stores, for example, a program recorded on a portable recording medium or a program transferred from a server computer in its own storage device. When executing the process, the computer reads a program stored in its own recording medium and executes a process according to the read program. As another execution form of the program, the computer may directly read the program from a portable recording medium and execute processing according to the program, and the program is transferred from the server computer to the computer. Each time, the processing according to the received program may be executed sequentially. Also, the program is not transferred from the server computer to the computer, and the above-described processing is executed by a so-called ASP (Application Service Provider) type service that realizes the processing function only by the execution instruction and result acquisition. It is good. Note that the program in this embodiment includes information that is used for processing by an electronic computer and that conforms to the program (data that is not a direct command to the computer but has a property that defines the processing of the computer).

  In this embodiment, the present apparatus is configured by executing a predetermined program on a computer. However, at least a part of these processing contents may be realized by hardware.
