Description

Technical Field

[0001] The present invention relates to a replacement processing program and a replacement processing method for performing replacement processing of a property information medium on which information about a property in real estate transactions is posted.

Background Art

[0002] Generally, a real estate broker accesses a real estate information database in which property information for real estate transactions (sale or lease) is registered and provides the property information to customers. As an example of such a database, there is REINS (registered trademark) (REINS: Real Estate Information Network System) operated and managed by a real estate distribution organization designated by the Minister of Land, Infrastructure, Transport and Tourism. A real estate broker can use the database with the company's terminal device and search for a large number of property information. In addition, materials (property information media) on which information such as price, location, and floor plan is posted can be downloaded, for example, as PDF (Portable Document Format). When a customer requests the material, the real estate broker can output it with a printer or the like after downloading and provide it to the customer.

[0003] By the way, this property information medium is created by a real estate agent (original agent) who has received a request from a person who wishes to sell or lease a property, and the company name, contact information, etc. of the original agent are described in the company information column. Therefore, the real estate broker provides the customer after replacing the company information column of the property information medium with the company's own information. This work is called "replacement". However, since the layout (position, size, etc.) of the property information medium varies from original agent to original agent and is not unified, the real estate broker has to perform individual editing work while checking the layout, and there is a problem that the work is complicated. To solve these problems, for example, Patent Document 1 proposes technology related to a property information management system that allows real estate agents to easily create real estate documents that reflect their own company information. According to this system, the position and shape of the company information field are stored as a layout pattern, and printable image data displaying the company's own company information is set as replacement image data. This allows for the automatic output of printable image data with the company's own company information inserted into the company information field, even if the printable image data has a different layout. Furthermore, a technology has been disclosed that uses image recognition algorithms such as AI to estimate the band portion, and if a band belonging to another company is detected through image recognition, that band is deleted and the buyer's company's band is inserted in that portion (Patent Document 2). [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Patent No. 6279000 [Patent Document 2] Patent No. 7412053 [Overview of the project] [Problems that the invention aims to solve]

[0005] In the aforementioned Patent Document 1, the technology described in Patent Document 1 involves pre-accumulating layout patterns of property information in a database and performing image replacement processing based on these patterns. However, because such a configuration is highly dependent on previously registered correct data, a problem arises when a new listing agent is added or when an existing listing agent changes the design or layout of the property information medium, as there is no pattern in the database corresponding to the changed layout. In such cases, automatic replacement cannot be performed, and ultimately, a human has to manually register information such as the position and size of the company information field into the database. Therefore, the effect of improving work efficiency through the introduction of the system is limited, and there is a problem that it leads to an increased operational burden, especially in a practical environment where property materials in various formats flow in daily from a large number of listing agents.

[0006] Furthermore, while using AI and other image recognition algorithms can be expected to provide a certain degree of automation, the problem of unstable reading accuracy remains. Specifically, the designs of the paper bands vary greatly from one supplier to another, and the color tone, transparency, font, and overlap with background images are not consistent, which can lead to false positives or false negatives in the image recognition process. As a result, there is a problem of reduced quality and reliability of the output materials. To improve reading accuracy, a vast amount of image data of the paper bands and the task of manually identifying them would be required, resulting in excessively high development costs.

[0007] This invention has been made in view of the above circumstances, and aims to provide a band-changing processing program and method that can easily and accurately perform "band-changing," which is the process of changing the band containing the original listing agent's information (lister information) in property documents (property information media) to a band containing the real estate broker's own information, thereby enabling the creation of property documents (property information media) that contain the broker's own company information. [Means for solving the problem]

[0008] The band replacement processing program of the present invention includes: an image data acquisition means that uses a computer included in a band replacement processing device connected to a plurality of terminal devices via a network to acquire image data based on document data that indicates a property information medium on which property information including publisher information is posted, which is the information of the publisher; a determination means that refers to a database that registers band replacement area information based on the position of a band area which is the area in the image data on which the publisher information is written, and the publisher information, and determines whether the band replacement area information associated with the publisher information of the image data acquired by the image data acquisition means is registered in the database; if, as a result of the determination by the determination means, the database does not have a registration of the band replacement area information associated with the publisher information of the image data acquired by the image data acquisition means, a band position identification means that analyzes the image data acquired by the image data acquisition means and identifies the position of a band area which is the area in the image data on which the publisher information is written; and the image data acquisition means that The system includes: a display control information transmission means that generates display control information showing a proposed band replacement area image for proposing a band replacement area by presenting the position of the band area identified by the band position identification means on an image based on image data, and transmits it to the terminal device which is the source of the document data; a correction reception means that receives a correction instruction for the band replacement area from the terminal device; an update means that updates the band replacement area based on the correction instruction received by the correction reception means; a band replacement processing means that places a band image in the updated band replacement area after the update by the update means, on which information of the user operating the terminal device which is the source of the document data is written instead of the publisher information of the image data, and generates image data in which the publisher information of the image data has been changed to the user information; a learning means that learns the position of the band area identified by the band position identification means based on the correction instruction received by the correction reception means; and a first storage control means that stores and stores the correction instruction in the database as correction history information, associating the band replacement area information, which is the position of the band area after learning by the learning means, with the publisher information of the image data, and the image data acquisition means isWhen the terminal device receiving the document data from any of the multiple terminal devices and acquiring new image data, the determination means refers to the database and determines whether the band replacement area information associated with the publisher information of the newly acquired image data is registered in the database. If, as a result of the determination by the determination means, the database is registered with the band replacement area information associated with the publisher information of the newly acquired image data, the system further includes a band replacement area information acquisition means to acquire the band replacement area information. The display control information transmission means generates display control information showing a band replacement area proposal image for proposing a band replacement area, which is the area where the publisher information of the image data is written, based on the band replacement area information acquired by the band replacement area information acquisition means, and transmits this to the terminal device that is the source of the new document data. The correction acceptance means is transmitted to the terminal device that is the source of the new document data. The device receives a modification instruction for the band replacement area, the update means updates the band replacement area based on the modification instruction received by the modification receiving means from the terminal device which is the source of the new document data, the band replacement processing means places a band image in the updated band replacement area, replacing the publisher information of the new image data with the information of the user operating the terminal device which is the source of the new document data, and generates image data in which the publisher information of the new image data has been changed to the information of the user operating the terminal device which is the source of the new document data, the learning means learns the position of the band replacement area based on the band replacement area information, based on the modification instruction received by the modification receiving means from the terminal device which is the source of the new document data and the modification history information stored in the database in association with the band replacement area information acquired by the band replacement area information acquisition means, and the first storage control means updates the band replacement area information stored in the database with band replacement area information which is the position of the band replacement area after learning by the learning means.The correction acceptance means is characterized by updating the correction history information based on the correction instructions received from the terminal device that is the source of the new document data.

[0009] The band position identification means may determine the position of the band region by reading the approximate position from the image data acquired by the image data acquisition means through AI-based image analysis processing, and then sequentially scanning the area around the approximate position row by row.

[0010] The system may include an analysis means for clustering the modified values ​​of the replacement areas included in the modification instruction history information to analyze patterns of the replacement areas, and a second storage control means for storing the replacement area information in association with the publisher information in the database for each pattern identified as a result of the analysis by the analysis means.

[0011] If there is no registration of the band position identification means associated with the publisher information of the image data, the band position identification means analyzes the image data acquired by the image data acquisition means and identifies the position of the band area, which is the area in which the publisher information of the image data is written, as a ratio to the length from the edge of the property information medium indicated by the image data. The display control information transmission means may generate the proposed band position image and display control information indicating the ratio, and transmit them to the terminal device which is the source of the document data.

[0012] The present invention relates to a band replacement processing method comprising a plurality of terminal devices and a band replacement processing device connected to each of the terminal devices via a network, comprising: an image data acquisition step in which the band replacement processing device acquires image data based on document data that indicates a property information medium on which property information including publisher information is published, which is document data transmitted from any of the terminal devices included in the plurality of terminal devices; a determination step in which the band replacement processing device refers to a database that registers band replacement area information based on the position of a band area which is an area of ​​the image data on which the publisher information is written, and the publisher information, and determines whether the band replacement area information associated with the publisher information of the image data acquired in the image data acquisition step is registered in the database; and if, as a result of the determination in the determination step, the band replacement processing device disassembles the image data acquired in the image data acquisition step if the database does not contain registration of the band replacement area information associated with the publisher information of the image data acquired in the image data acquisition step. A band position identification step in which the band area is an area in which the publisher information of the image data is described is analyzed and the position of the band area is identified; a band replacement area information acquisition step in which, as a result of the determination in the determination step, the band replacement processing device acquires the band replacement area information if the database has registered the band replacement area information associated with the publisher information of the image data acquired in the image data acquisition step; a display control information transmission step in which the band replacement processing device generates display control information showing a band replacement area proposal image for proposing a band replacement area by presenting the position of the band area identified in the band position identification step, or the position of the band area based on the band replacement area information acquired in the band replacement area information acquisition step, on an image based on the image data acquired in the image data acquisition step, and transmits it to the terminal device which is the source of the document data; a correction acceptance step in which the band replacement processing device receives a correction instruction for the band replacement area from the terminal device; an update step in which the band replacement processing device updates the band replacement area based on the correction instruction received in the correction acceptance step; and the band replacement processing deviceThe process includes: a band replacement processing step in which, after updating the band replacement area by the update step, a band image containing information of the user operating the terminal device that transmits the document data is placed in place of the publisher information of the image data, and an image data is generated in which the publisher information of the image data has been changed to the user information; a learning step in which the band replacement processing device learns the band replacement area related to the proposed band replacement area image based on the correction instructions received in the correction acceptance step; and a first storage control step in which the band replacement processing device stores the band replacement area information learned in the learning step in association with the publisher information of the image data in the database, and stores the content of the correction instructions received in the correction acceptance step as correction history information in association with the publisher information of the image data, wherein in the learning step, if there is correction history information in the database associated with the publisher information of the image data, the band replacement area related to the proposed band replacement area image is learned based on the content of the correction instructions received in the correction acceptance step and the correction history information. [Effects of the Invention]

[0013] According to the band replacement processing program of the present invention, band replacement area information is registered in association with the publisher information of the image data, along with the modification history information for the band replacement area. Therefore, high-precision band replacement processing can be performed using band replacement area information that has been learned by taking into account the accumulated modification history information of multiple users. According to the band replacement processing method of the present invention, since band replacement area information is registered in association with the publisher information of the image data, along with the modification history information for the band replacement area, high-precision band replacement processing can be performed using band replacement area information that has been learned by taking into account the accumulated modification history information of multiple users.

[0015] Embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely illustrative, and there is no intention to exclude various modifications or applications of techniques not explicitly stated below. That is, the present invention can be implemented in various modifications (combining the configurations of each embodiment and modified example, etc.) as long as it achieves its effects.

Furthermore, in order to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art, detailed explanations of already well-known matters and redundant explanations of substantially identical configurations and processes may be omitted.

[0016] The band replacement processing program according to this embodiment includes: an image data acquisition means that uses a computer included in a band replacement processing device connected to a plurality of terminal devices via a network to acquire image data based on document data that indicates a property information medium on which property information including publisher information is posted, which is the information of the publisher; a determination means that refers to a database that registers band replacement area information based on the position of the band area, which is the area in the image data on which the publisher information is written, and the publisher information, and determines whether the band replacement area information associated with the publisher information of the image data acquired by the image data acquisition means is registered in the database; and, if, as a result of the determination by the determination means, the database does not contain the band replacement area information associated with the publisher information of the image data acquired by the image data acquisition means, a band position identification means that analyzes the image data acquired by the image data acquisition means and identifies the position of the band area, which is the area in the image data on which the publisher information is written; and the image data acquisition means The system includes: a display control information transmission means that generates display control information indicating a proposed band replacement area image for proposing a band replacement area by presenting the position of the band area identified by the band position identification means on an image based on the image data acquired by the system, and transmits this information to the terminal device which is the source of the document data; a correction reception means that receives a correction instruction for the band replacement area from the terminal device; an update means that updates the band replacement area based on the correction instruction received by the correction reception means; a band replacement processing means that places a band image in the updated band replacement area after the update by the update means, in which information of the user operating the terminal device which is the source of the document data is written instead of the publisher information of the image data, and generates image data in which the publisher information of the image data has been changed to the user information; a learning means that learns the position of the band area identified by the band position identification means based on the correction instruction received by the correction reception means; and a first storage control means that stores and stores the correction instruction in the database as correction history information, associating the band replacement area information, which is the position of the band area after learning by the learning means, with the publisher information of the image data.When the image data acquisition means newly receives the document data from any of the terminal devices included in the plurality of terminal devices and acquires new image data, the determination means refers to the database and determines whether the band replacement area information associated with the publisher information of the newly acquired image data is registered in the database. If, as a result of the determination by the determination means, the band replacement area information associated with the publisher information of the newly acquired image data is registered in the database, the further band replacement area information acquisition means acquires the band replacement area information. The display control information transmission means generates display control information showing a band replacement area proposal image for proposing a band replacement area, which is the area in which the publisher information of the image data is written, based on the band replacement area information acquired by the band replacement area information acquisition means, and transmits it to the terminal device that is the source of the new document data. The modification acceptance means accepts a modification instruction for the band replacement area from the terminal device, and the update means The modification receiving means updates the band replacement area based on the modification instructions received by the modification receiving means, the band replacement processing means places a band image containing information of the user operating the terminal device that is the source of the new document data in place of the new image data publisher information in the band replacement area after the update by the update means, generates image data in which the new image data publisher information has been changed to the information of the user operating the terminal device that is the source of the new document data, the learning means learns the position of the band area based on the band replacement area information based on the modification instructions received by the modification receiving means from the terminal device that is the source of the new document data and the modification history information stored in the database in association with the band replacement area information acquired by the band replacement area information acquisition means, the first storage control means updates the band replacement area information stored in the database to band replacement area information which is the position of the band area after learning by the learning means, and the modification receiving means updates the modification history information based on the modification instructions received by the terminal device that is the source of the new document data.

[0017] The band replacement processing system S, which includes a band replacement processing device 1 having a control unit as a computer that executes the band replacement processing program of the present invention, is a system for supporting the "band replacement" of property information media (property documents) for users such as real estate agents who broker the buying, selling, and leasing of real estate such as condominiums, detached houses, land, and commercial properties. This system includes a band replacement processing device 1 equipped with a control unit and provides a function to automatically replace the band containing the information of the listing agent (original agent) on the property information media (mysoku) with a band containing the information of the user.

[0018] In the following explanation, we will describe an example where a representative of a real estate brokerage firm, as a user, operates terminal device 2A and transmits document data, such as PDF data, of property information media to the label replacement processing device 1 via network 100, and receives image data from the label replacement processing device 1 that has been replaced with the label image of their own company (the user). Note that the document data is not limited to PDF data; any data that can be visually confirmed by text and layout, such as image data, consisting of text information and image information, is acceptable.

[0019] Figure 1 is a schematic diagram showing an example of the configuration of the band replacement processing system S in this embodiment. The band replacement processing system S according to this embodiment consists of a band replacement processing device 1 and terminal devices 2A to 2E, etc., connected to the band replacement processing device 1 via a network 100 to enable the exchange of information. The network 100 includes LAN (Local Area Network), WAN (Wide Area Network), the Internet, or an intranet.

[0020] The band replacement processing device 1 is a device installed by the system provider that sets up the band replacement processing system S. The band replacement processing device 1 may be an information processing device such as a laptop computer or a tablet terminal. Terminal devices 2A to 2E exist in multiple locations within the band replacement processing system S and are composed of, for example, personal computers, tablet computers, smartphones, etc., that can access the band replacement processing device 1 via the network 100. A representative of a real estate agent operates terminal devices 2A to 2E to send, for example, document data indicating a property information medium (MySoku) obtained from a real estate information database (not shown) to the band replacement processing device 1 and request band replacement processing.

[0021] A real estate information database is a database that stores property information, such as REINS (registered trademark) operated by the Real Estate Distribution Organization. Property information media are documents that introduce properties, called MySoku, which contain property information (for example, documents containing floor plans showing the property layout, maps showing the property's location, images showing the property's exterior, documents containing detailed information such as property number, transaction type, transaction information, price, zoning, and floor area, and documents containing information about the person who posted the property information). When terminal devices 2A to 2E obtain document data indicating the property information media from the real estate information database, the company name and contact information of the person who created (posted) the document (listing agent) are printed on the band.

[0022] Figure 2 is a schematic block diagram showing the configuration of the band replacement processing device 1. The band replacement processing device 1 is configured as a computer consisting of a CPU (Central Processing Unit) with arithmetic functions, a working RAM (Random Access Memory), a ROM (Read Only Memory) or a hard disk drive for storing various data and programs, a storage unit 12 equipped with a hard disk drive, a display unit 13 equipped with a display screen such as a monitor, an input unit (e.g., keyboard, mouse, operation panel (including touch panel), etc.) 14 that receives instructions from the operator of the band replacement processing system S and provides instruction signals to the control unit 11 in accordance with those instructions, and a communication unit 15 for communicating with terminal devices 2A to 2E, a real estate information database 3, etc. via a network 100 (including a LAN (Local Area Network)). Each component is interconnected via a bus.

[0023] The storage unit 12 includes a user information database DB1 and a replacement information database DB2. Figure 3 shows an example of information registered (stored) in the user information database DB1, and Figure 4 shows an example of information registered (stored) in the replacement information database DB2. The user information database DB1 stores user identification information (USER1, USER2, ...) that uniquely identifies a user when they register to use the bag replacement processing system S (or as instructed by the real estate agent), and bag image data (IMAGE1, IMAGE2, ...) that contains the user's information (information of the real estate agent (company name, contact information, etc.)), in association with each other.

[0024] For example, a representative of a real estate agent operates terminal device 2A and transmits authentication information to the band replacement processing device 1 via the network 100 to the band replacement processing system S. Authentication information includes user identification information that uniquely identifies the person in charge (including individuals and organizations). For example, it is a pair of user ID and password, which is an example of user identification information assigned by the band replacement processing system S (or instructed by the person in charge) when the person in charge registered to use the band replacement processing system S.

[0025] The person in charge operates the input section 24 of terminal device 2A to input authentication information (user identification information (e.g., USER1) and password), and transmits this authentication information to the band replacement processing device 1. The band replacement processing device 1 receives the authentication information transmitted from terminal device 2A and performs login authentication for the band replacement processing system S. Specifically, it compares this information with multiple authentication pieces of information that have been pre-registered in the user registration database (not shown) as users of the band replacement processing system S, and grants login if authentication is successful.

[0026] The person in charge operates terminal device 2A to send band image data (for example, IMAGE1) containing their company's information (company name, contact information, etc.) to band replacement processing device 1. Upon receiving this, band replacement processing device 1 associates the band image data (IMAGE1) with user identification information (USER1) and registers it in the user information database DB1. For example, the above procedure is used to register each user's band image data in the user information database DB1.

[0027] The listing area information database DB2 stores (stores) information about the listing agent (original agent) who creates (provides) the property listing medium (e.g., company name), such as listing agent information (FUDOSAN1, FUDOSAN2, ...), and listing area information (AREA1, AREA2, ...) based on the location of the listing area, which is the area in the image data obtained from the PDF or other document data representing the property information medium in which the listing agent information is written. This listing area information was registered in the past when it was determined as listing area information using the listing area processing system S and the listing area processing procedure described later.

[0028] Furthermore, when the band replacement area information is determined, the revision history of that area is registered as revision history information (Rev1, Rev2, ...) and associated with the publisher information and the band replacement area information. In this embodiment, the user information database DB1 and the replacement information database DB2 are provided in the storage unit 12, but these databases may also be provided in an external database accessible from the replacement processing device 1.

[0029] The control unit 11 implements various functions, for example, by having the processor execute a program stored in memory. The processor may include an MPU (Micro Processing Unit), CPU, DSP (Digital Signal Processor), GPU (Graphical Processing Unit), etc.

[0030] Each means and function of the control unit 11 is executed according to a program (including the band change processing program of the present invention) stored in ROM or the like, but each may be configured with an independent device or with cloud computing. The storage unit 12 may also be configured with a cloud service. The control unit 11 works in cooperation with other components to function as the image data acquisition means, band position identification means, determination means, display control information transmission means, correction acceptance means, update means, band replacement processing means, learning means, first memory control means, band replacement area information acquisition means, analysis means, and second memory control means of the present invention.

[0031] The band position identification means of the control unit 11 instructs the AI ​​(Artificial Intelligence) to analyze image data based on document data transmitted from terminal devices 2A to 2E to identify the position of the band area, which is the area in which the publisher information of the image data is written, and obtains the result. For example, Google's Gemini or Anthropic's Claude can be used as the AI. The AI ​​may be built locally and accessed by the control unit 11 via a LAN (Local Area Network), or it may be accessed via a WAN (Wide Area Network).

[0032] <Band replacement processing> An example of the operation of the band change processing system S will be described. In the operation of the band change processing system S, communication is performed between the band change processing device 1 and the terminal device 2A via the network 100, communication unit 15, and communication unit 25. However, unless otherwise specified, the explanations "via network 100," "via communication unit 15," and "via communication unit 25" will be omitted. In the following explanation, we will use the example of a case where a representative of a real estate brokerage company, who is the user, operates terminal device 2A to perform the band change process.

[0033] Figure 5 is a sequence diagram showing the band replacement process performed by the band replacement processing system S. In this embodiment, the control unit 11 of the band replacement processing device 1 sequentially executes the processing of each step except for the processing by the terminal device 2A, in accordance with the band replacement processing program of the present invention, and functions as the image data acquisition means, band position identification means, determination means, display control information transmission means, correction acceptance means, update means, band replacement processing means, learning means, first memory control means, and band replacement area information acquisition means of the present invention.

[0034] First, the control unit 11 of the band replacement processing device 1 converts each page into an image and acquires image data (step S102) based on document data such as property information medium PDF (MySoku PDF) transmitted (step S101) from the terminal device 2A that has performed login authentication to the band replacement processing system S. Then, it refers to the band replacement information database DB2 and determines whether or not band replacement area information is registered in the database (step S103).

[0035] Specifically, for example, optical character recognition (OCR) is performed on the acquired image data to determine whether the same company name as the listing agent indicated in the listing agent information document shown in the image data is registered in the listing agent information database DB2. If the listing agent information is not registered in the listing agent information database DB2, it is determined that there is no listing agent information registered either.

[0036] If the determination results in no registration of band replacement area information in the band replacement information database DB2 (step S103: No), the image data obtained in step S102 is analyzed by AI or the like to identify the location of the band area, which is the area where the publisher information is written (step S104).

[0037] First, the AI ​​uses image analysis processing to examine the entire image data and read the approximate locations of company names, phone numbers, logos, addresses, etc. Then, it sequentially scans line by line to pinpoint the detailed locations. Specifically, the AI ​​uses image analysis processing to determine that the area containing the company name, phone number, logo, address, etc., is a band on the property information medium, and the position of the top edge of this band is estimated as the position of the band area using the ratio of its length from the top edge of the property information medium to the page height.

[0038] Next, starting from the estimated position of the band area (approximately 0.8 = approximately 80% from the top of the page), the surrounding area is scanned row by row using actual image pixels, precisely detecting the boundaries of the band area (changes in brightness, separator lines, etc.), and finally identifying the position of the band area (0.82 = 82% from the top of the page). In other words, (1) The AI ​​will give a rough estimate (rough position information), (2) The area around the range indicated by the AI ​​is checked pixel by pixel to identify the exact boundary coordinates (in dot units) (detailed position). By combining primary detection by AI (coarse accuracy, high speed) and pixel-precise correction (high accuracy, low speed), the position of the band area can be identified with high accuracy and efficiency.

[0039] Next, display control information is generated showing a proposed band replacement area image, which presents the position of the band area identified in step S104 on an image based on the image data acquired in step S102, and is transmitted to the terminal device 2A (step S105).

[0040] On the other hand, if, as a result of the determination in step S103, there is a listing agent with the same company name as the listing agent indicated in the listing agent information written in the property information medium indicated by the image data obtained in step S102, and there is a listing area information registered in the listing area information database DB2 (step S103: Yes), then the listing area information registered in association with the listing agent information is obtained from the listing area information database DB2 (step S121).

[0041] Then, based on the image data acquired in step S102, display control information is generated to show a proposed band replacement area image, which indicates the location of the band area, which is the area in which the publisher information of the image data is written, based on the band replacement area information acquired in step S121, and is transmitted to the terminal device 2A (step S105).

[0042] Based on the display control information transmitted from the band replacement processing device 1, the terminal device 2A displays a proposed band area image on the display monitor of the display unit 23 of the terminal device 2A (step S106) and accepts input of a band replacement area correction instruction (step S107). Figure 6 shows an example of a display monitor showing a proposed band area image. The proposed band area image in Figure 6 is an example in which the position 51 of the band area is visualized with a dotted line, corresponding to an image based on image data representing the property information medium. The band area range 52 extends from the position 51 of the band area to the bottom edge of the property information medium. In Figure 6, the band area range 52 in the property information medium is enclosed by a dashed line, but the display of the band area range 52 is optional.

[0043] The operator adjusts the position of the band area 51 as needed by operating the input unit 24 while viewing the proposed band area image on the display monitor of the display unit 23 of the terminal device 2A. For example, the system is configured so that the position of the band area 51 can be finely adjusted vertically by clicking the position adjustment buttons 53 and 54 as shown in Figure 6.

[0044] Figure 7 is an explanatory diagram of the adjustment of the band area position, and is an example of the display monitor showing the proposed band area image after the position 51 of the band area has been corrected by the person in charge. After such fine adjustment (Figure 7), clicking the confirm button 55 sends a band replacement area correction instruction to the band replacement processing device 1. Furthermore, when the person in charge adjusts the position 51 of the banner area, a numerical value may be displayed so that the current position of the banner area can be quantitatively determined. Figures 8 and 9 show examples of how the position 51 of the banner area is adjusted from 84% of the top of the page (Figure 8) to 82% (Figure 9).

[0045] In this way, by identifying the position of the band area as a ratio (e.g., 82%) to the length from the top edge of the property information medium indicated by the image data, and configuring the system to display this ratio together with the proposed band replacement area image, the person in charge can easily visually grasp the band replacement area and make corrections.

[0046] When the band replacement processing device 1 receives a band replacement area modification instruction from the terminal device 2A (step S108), it updates the band replacement area based on the content of the received modification instruction (modification instruction content) (step S109). Then, it performs a band replacement process on the updated band replacement area (step S110). First, it obtains band image data from the user information database DB1 that contains information about the user operating the terminal device 2A, which is the source of the document data that forms the basis of the image data obtained in step S102. Specifically, it obtains band image data (IMAGE1) corresponding to the user identification information (USER1) used when performing login authentication.

[0047] Next, the band image shown by the band image data (IMAGE1) is placed in the updated band replacement area. This generates image data in which the publisher information of the original image data has been changed to the user's information. Then, the control unit 11 performs the band replacement process in step S110 and transmits the generated band-replaced image data to the terminal device 2A (step S111). The image data may also be sent as document data such as PDF data.

[0048] The band replacement can be done by overwriting the original band image containing the publisher's information with a band image based on the user's band image data (IMAGE1), or by deleting the original band image containing the publisher's information and then placing the band image based on the user's band image data (IMAGE1). In either case, the band image based on the user's band image data (IMAGE1) is scaled and placed to match the band replacement area. Furthermore, if the aspect ratio of the band image differs from that of the band replacement area, the band image may be scaled while maintaining its aspect ratio, and the resulting margins may be removed. This allows the band image to be positioned without compromising the design based on the user's band image data (IMAGE1).

[0049] Terminal device 2A acquires image data from the band replacement processing device 1 (step S112). Figure 10 shows an example of the display on the display monitor of the display unit 23 of terminal device 2A, which displays an image based on the image data after the band replacement processing acquired in step S112. The band area contains a band image 56 with user information, based on the user's band image data (IMAGE1). For example, by operating the input unit 24 and clicking the save button 57, the image data after the band replacement processing transmitted from the band replacement processing device 1 can be downloaded and saved as a property information medium PDF within terminal device 2A or elsewhere.

[0050] Furthermore, the control unit 11 learns the position of the band area based on the correction instruction received in step S108 (step S113), and registers the band replacement area information (AREA1), which is the position of the band area after learning, in the band replacement information database DB2 in association with the publisher information (FUDOSAN1) of the image data. In addition, the correction instruction received in step S108 is stored and registered in the band replacement information database DB2 as correction history information (Rev1), in association with the publisher information (FUDOSAN1) of the image data (step S114), and the process ends.

[0051] Furthermore, in the learning process of step S113, if, as a result of the determination in step S103, there is registration of replacement area information in the replacement information database DB2 (step S103: Yes), and the replacement area information is obtained from the replacement information database DB2 (step S121), then in addition to the correction instructions received in step S108, the location of the replacement area is learned based on the correction history information registered in association with the replacement information database DB2.

[0052] For example, if the publisher information in the property information medium indicated by the image data acquired from terminal device 2A in step S102 is the same as the publisher information (FUDOSAN3) registered in the replacement information database DB2, then replacement area information (AREA3) associated with the publisher information (FUDOSAN3) will be acquired in step S121. In this case, during the learning in step S113, the location of the area is learned not only based on the correction instructions received in step S108, but also based on the correction history information (Rev3) registered in the replacement information database DB2.

[0053] Through the above process, it becomes possible to easily and accurately "change the band" on image data indicating property information media, replacing the band containing the publisher's information with a band representing the real estate agent themselves, thereby easily creating real estate documents that include their own company information.

[0054] In particular, the band change area information was registered in association with the image data publisher information, along with the modification history information for the band change area. In the embodiment described above, the band change process accessed by the person in charge of terminal device 2A was explained as an example, but the same band change information database DB2 will also be used in the case of band change processes accessed by other persons in charge from other terminal devices 2B, etc. That is, the band change information database DB2 is configured to store and accumulate modification instructions from multiple users linked in chronological order as modification history information.

[0055] This allows for the use of correction instructions from multiple users through a learning mechanism, enabling optimization through the sharing of knowledge from multiple users and collaborative tuning. It also allows for a high level of stability in the accuracy of the band change area position.

[0056] Furthermore, when learning the position of the band region in step S113, the learning is performed taking into account not only the most recent correction instruction (S108) but also the information accumulated as correction history information. In this way, by using a learning method that takes into account not only the most recent correction instruction but also the accumulated correction history information, it is possible to suppress overfitting associated with local corrections and absorb fluctuations in corrections made by a single user by reflecting past correction trends.

[0057] <Other examples of area location identification processing> Incidentally, the name and phone number of the listing agent (original agent) are printed within the banner of the property information media, and this text is located inside the banner. In other words, this text is below the banner's position (the top edge of the banner). This characteristic of placement can be used to determine the location of the banner area.

[0058] Figure 11 is a flowchart illustrating an example of the band region location identification process in step S104. First, the control unit 11 determines whether the processing has exceeded a predetermined number of times (step S141). If it has not exceeded a predetermined number of times (step S141: No), it performs AI-based image analysis on the image data acquired in step S102 and scans the area around the range indicated by the AI ​​row by row to estimate the position of the band (obi_top) (step S142). Similarly, it estimates the position of the company name (name_top) and telephone number (telno_top) of the advertiser (original agent) within the band (steps S143, S144). The upper end positions of each are estimated as a ratio to the length from the top edge of the property information medium (page height).

[0059] Next, it is determined whether the band position (obi_top) is greater than or equal to the company name position (name_top) (step S145) or greater than or equal to the telephone number position (telno_top) (step S146). If the band position (obi_top) is greater than or equal to the company name position (name_top) (step S145: Yes) or greater than or equal to the telephone number position (telno_top) (step S146: Yes), the detection is rejected and re-estimation is performed because the top edge of the band cannot be lower than the telephone number (step S141).

[0060] If the band position (obi_top) is neither above the company name position (name_top) nor above the telephone number position (telno_top) (step S145: No, step S146: No), then it is determined whether the telephone number position (telno_top) is significantly below the band position (obi_top) (step S147). For example, a predetermined reference value (R_th) is set to make the determination. If the telephone number position (telno_top) is not significantly below the band position (obi_top) (step S147: No), then the band position (obi_top) estimated in step S142 is identified as the position of the band area (step S149). for example, The phone number position (telno_top) is (position from the top of the page: 0.88), The band position (obi_top) is (position from the top of the page: 0.82) Prescribed reference value (R_th) = 0.15 In that case, the judgment in step S147 will be No.

[0061] On the other hand, if the telephone number position (telno_top) is significantly lower than the band position (obi_top) (step S147: Yes), or if the number of steps in step S141 exceeds a predetermined number (step S141: Yes), the process proceeds to step S148. for example, The phone number position (telno_top) is (position from the top of the page: 0.98), The band position (obi_top) is (position from the top of the page: 0.80) Prescribed reference value (R_th) = 0.15 In that case, the determination in step S147 will be Yes.

[0062] Then, in step S148, statistical estimates based on statistical values ​​obtained from past processing results are acquired and identified as the location of the zone (step S149). Statistical estimates are calculated by accumulating the difference between the telephone number location (telno_top) and the band location (obi_top) when the band location estimated in step S142 was used in past processing, and pre-calculating the average deviation. For example, the band location (obi_top) is estimated using this deviation relative to the telephone number location (telno_top). For example, if it is found that the telephone number location (telno_top) is, on average, 0.07 larger than the band location (obi_top), this is used to identify the location of the band area.

[0063] This processing method allows for the avoidance of processing interruptions due to analysis failures, even if the location of the zone cannot be precisely determined due to some factor. This enables continuous processing of zone location with a consistently high level of reliability.

[0064] Furthermore, in the band area location determination process in step S104, representative value reporting by packet discretization may be used. Simply put, when you have the AI ​​analyze the location of a banded area and ask it for its location, it tries to answer with a very precise number (a continuous value) like "87.35487...%". However, there is noise in the image data, such as slight differences in brightness, and the AI ​​reacts to this too sensitively. As a result, even for the same image data, the result may fluctuate, sometimes being "87.3%" and other times "87.8%", resulting in a lack of consistency.

[0065] Therefore, we adopt a method in which the AI ​​classifies the data into predetermined discrete intervals (packets). Specifically, we prepare fixed intervals (packets) in advance, such as "82.5% to 84.9%", "85.0% to 87.4%", ... "87.5% to 90%", and have the AI ​​determine which interval the analyzed region belongs to. The AI ​​is then configured to report the median value of that interval, "88.75%", as the representative value. This allows us to obtain stable (consistent) answers that are not misled by minor noise.

[0066] Discrete intervals (packets) can be prepared, for example, in 2.5% increments in normal mode and 1% increments in high-precision detection mode. By first ensuring stability (consistency) in discrete intervals and then performing a row-by-row scan, it is possible to achieve both noise immunity and high-precision localization. Furthermore, representative value reporting based on packet discretization may be used when estimating the location of the company name (name_top) (step S143) and the location of the telephone number (telno_top) (step S144).

[0067] <Application Example 1> The band-changing process described above was explained using a single-page property information medium as an example (Figures 6 to 10), but there is also a format called 2-in-1 in which information on two properties is arranged vertically. In this format, the upper half contains information on the first property, and the lower half contains information on the second property, with a band containing information on the advertiser (listing agent) placed near the center of the page (for example, 40% to 52% from the top of the page).

[0068] The system is designed to allow for smooth band replacement even when the single-disc format and the 2-in-1 format are mixed together. In step S104, the control unit 11 first checks for a band near the center of the page using image analysis such as AI. At this time, it checks whether the band is within a predetermined margin range (for example, 35% to 55% from the top edge of the page). If a band is present, it is determined that it is a 2-in-1 format.

[0069] If there is no band near the center of the page, check whether there is a band at the bottom of the page (for example, 75% to 95% from the top of the page). If there is a band, it is determined to be a single-page format, and the band replacement process is performed according to the single-page format processing described above. If there is no band at the bottom of the page either, it is determined to be no band.

[0070] If it is determined that the format is 2-in-1, the process of changing the label must be handled in a way that prevents the property information located in the lower half from being accidentally deleted. Therefore, the control unit 11 fixes the page boundary position (for example, 51% from the top edge) as the upper limit of the erasure area and fills that area with white. Then, it scales and positions the band image data (IMAGE1) containing the user's information so that it fits within that area. Figure 12 shows an example of a display monitor showing a proposed band area image when the property information medium is in a 2-in-1 format.

[0071] The person in charge can use the label replacement system S without having to be aware of whether the property information medium to be replaced is in a single-page format or a 2-in-1 format.

[0072] <Application Example 2> In the real estate industry, property information media with different layouts / formats may be provided by the same listing agent. To apply the present invention to such property information media from the same listing agent that consist of multiple layouts / formats with different sizes and positions of bands, the control unit 11 may function as an analysis means and a second storage control means to analyze the pattern of the band change area and register the band change area information for each pattern in the band change information database DB2.

[0073] Specifically, in step S114, the control unit 11 associates the content of the correction instruction received in step S108 with the publisher information (FUDOSAN1) and registers it as correction history information (Rev1). At that time, it compares the correction value indicated by the received correction instruction with the correction history information (Rev1) to determine whether it is greater than, for example, a predetermined threshold.

[0074] If the correction value is determined to be greater than a predetermined threshold, it is analyzed as a different pattern of the re-covering area and registered as re-covering area information for a different pattern in the re-covering information database DB2. Multiple patterns of re-covering area information (AREA1(A), AREA1(B), etc.) associated with the publisher information (FUDOSAN1) will be registered in the re-covering information database DB2. Figure 13 is an example of information registered (stored) in the re-covering information database DB2.

[0075] For example, in step S121, multiple band replacement area information is acquired, and display control information showing multiple band replacement area proposal images is generated for each acquired band replacement area information, and transmitted to terminal device 2A. Furthermore, the system may be configured so that the person in charge operates the input unit 24 to select one of the multiple proposed band replacement area images displayed on the display monitor. Correction history information based on the correction instructions for the band replacement area is also accumulated for each pattern, that is, for each band replacement area information (Rev1(A), Rev1(B)).

[0076] <No authentication required> In the embodiment described above, login authentication was used, but the system may be configured without login authentication. In this case, for example, terminal device 2A transmits both document data of the property information medium for which the band replacement process is desired and band image data containing the company's information to the band replacement processing device 1. Band replacement processing device 1 performs the processing in steps S104 to S109 on the image data acquired based on the transmitted document data, performs the band replacement process in step S110 using the band image data transmitted together with the document data, and transmits the image data after the band replacement process to terminal device 2A in step S111.

[0077] <Generation of band image data by band replacement processing device 1> Furthermore, the band replacement processing device 1 may generate band image data for each user. For example, it may obtain document data of the property information medium for which the band replacement processing is desired from the terminal device 2A, and also have the terminal device 2A input information of the company (brokerage real estate company) (company name, address, telephone number, license number, name of person in charge, etc.) from the input unit 24, which the band replacement processing device 1 obtains as text data. Then, when performing the band replacement process in step S110, a band image is generated based on this text data, and the band replacement process is performed using this band image.

[0078] For example, the control unit 11 dynamically calculates the height of the band according to the number of input fields (items of input information), and automatically selects a 1-tier, 2-tier, or 3-tier layout according to the height to generate the band image. The design of the obi (sash) (height and number of tiers) can be automatically adjusted to look just right based on the amount of information entered.

[0079] <Implementation Examples> Figure 14 shows an example of a band replacement processing flow executed by a control unit 11 that can be implemented in the band replacement processing device 1. As described in Application Example 2, there are cases where multiple layouts / formats exist even for property information media from the same listing agent. For example, if "AAAA Real Estate Co., Ltd." uses two patterns, a single-page format (85% band position) and a 2-in-1 format (87.5% band position), both patterns are registered in the band change information database DB2. Using the rough detection value by AI (e.g., 86%) as a hint, the numerically closest pattern (87.5%) is selected. The patterns are configured to be automatically generated by statistical clustering of the revision history. Statistical clustering of the revision history may involve recognizing, for example, a pattern where there are two or more revisions for the same company and a standard deviation of less than 0.015.

[0080] Figure 15 shows an example of a specification that can be implemented in the replacement information database DB2. Even if multiple modifications are made, an INSERT statement will be inserted each time, and the entire modification history will be registered with a timestamp. UPDATE statements will not be used. Since the replacement information database DB2 is rebuilt from the entire modification history at startup and after each processing completion, a learning loop is formed where accuracy automatically improves as the modification history accumulates.

[0081] <Two-stage detection and dynamic branching> In step S103, when switching processing paths, a combination of AI-based primary detection (coarse accuracy, high speed) and pixel-precise correction (high accuracy, low speed) can be used to determine whether or not the publisher information is already registered. This allows for an efficient processing flow without performing costly precision processing on all items.

[0082] <Multi-pattern nearest neighbor selection using coarse detection values> As described in Application Example 2, etc., in order to efficiently handle multiple layouts / formats of property information media from the same listing agent, the "rough values ​​of the band positions detected by AI" can be used as selection hints from the corrected high-precision pattern set. The AI's primary output is not discarded but reused to improve the final accuracy.

[0083] <Learning platform based on quantitative recording of correction differences> When registering correction history information in the band replacement information database DB2, it is also possible to configure the system to register correction_delta (correction difference) and was_corrected (manual correction flag) separately. Rather than simply accumulating correction history, quantitatively recording "how much it was off" enables statistical evaluation and continuous improvement of AI detection accuracy.

[0084] <Automatic pattern generation using statistical clustering> As explained above, the system is configured so that layout patterns are automatically registered for each listing agent based on statistical analysis of the revision history (threshold determination based on frequency of occurrence and standard deviation), without requiring the system provider setting up the listing replacement processing system S or the users of terminal devices 2A to 2E to explicitly register the layout patterns of the property information media. This enables the realization of a self-learning listing replacement processing system S that eliminates the need for manual creation of training data.

[0085] Although the band replacement processing system S of the present invention is configured with each means provided by the band replacement processing device 1 and terminal devices 2A to 2E, it may also be realized by a system in which multiple devices are configured to be able to access each other.

[0086] The above-described configuration of the band replacement processing system S and its application examples and modifications merely explain the basic points for realizing the band replacement processing program and band replacement processing method of the present invention. In other words, the technical scope of the band replacement processing program and band replacement processing method according to the present invention is not limited to the scope described in each of the embodiments described above, and various changes or improvements can be made within the scope of the claims.

[0087] The scope of application of the present invention is not limited to the configuration described above. The present invention can be broadly applied to a label replacement processing program and a label replacement processing method that can easily and accurately perform label replacement processing of property information media.
