Summary of the Invention

Problems to be Solved by the Invention

[0004] However, among the states of vacant houses, there are some states where there is no particular problem even if they are left as they are, and there are also some states where, if left as they are, they may cause damage to adjacent properties, for example, due to collapse. In the technique disclosed in Patent Document 1, it is impossible to distinguish between a state where there is no particular problem and a state where there is a risk of causing damage to adjacent properties among the states of the target property being vacant, and it was necessary to dispatch an investigator to the site of the property to grasp the detailed state.

[0005] The present invention has been made in consideration of the above points, and aims to propose a property state determination system that can estimate the detailed state of a property without dispatching an investigator to the site of the property.

Means for Solving the Problems

[0006] To solve these problems, the present invention includes a data input unit that receives exterior image data including the characteristics of the exterior image of the target property; a power supply amount storage unit that stores power supply amount data indicating the amount of power supplied to the property; and a specific state determination unit that determines, based on the power supply amount data, whether the target property is in a first state where it is not used on a daily basis, or in a second state where it is used on a daily basis. The specific state determination unit includes an idle state determination unit that determines, based on the power supply amount data, that the power supplied to the target property is standby power below a predetermined threshold, and determines that the target property falls under the idle state of the first state, which is likely to be used on a daily basis in the future; and a vacant state determination unit that determines, based on the exterior image data, whether the target property falls under the specific vacant state where it may affect the surrounding area, or under the vacant state where it does not likely affect the surrounding area.

[0007] In the present invention, the specific state determination unit reads power supply amount data from a power supply amount storage unit where power supply amount data indicating the amount of power supplied to the property is stored, and determines, based on the power supply amount data, whether the target property is in a first state where it is not used on a daily basis, or in a second state where it is used on a daily basis; the idle state determination unit determines, based on the power supply amount data, that the power supplied to the target property is standby power below a predetermined threshold, and determines that the target property falls under an idle state among the first states where it may still be used on a daily basis in the future; and the vacant house state determination unit determines, based on an exterior image including the characteristics of the exterior image of the target property, whether the target property falls under a specific vacant house state where it may affect the surrounding area, or a vacant house state where it does not affect the surrounding area. [Effects of the Invention]

[0008] According to the present invention, it is possible to estimate the detailed condition of an unoccupied property without having to dispatch an investigator to the property site. [Brief explanation of the drawing]

[0009] [Figure 1] This is a system configuration diagram showing an example of the configuration of the property condition determination system according to the first embodiment. [Figure 2] Figure 1 shows an example of the structure of the property information table in the property management database. [Figure 3] This flowchart shows an example of the procedure for determining the property type according to this embodiment. [Figure 4] This flowchart shows an example of the procedure for determining the property status in this embodiment. [Modes for carrying out the invention]

[0010] Hereinafter, this embodiment of the present invention will be described in detail with reference to the drawings. (1) First Embodiment The property status determination system according to the first embodiment is a system that determines the status of a target real estate property (hereinafter simply referred to as "property"), such as whether or not the target property is vacant.

[0011] In this embodiment, the state of the property can be broadly classified into, for example, a first state in which the user uses the property on a daily basis, and a second state in which the user does not use the property on a daily basis. The second state, as will be described in detail later, includes three types of states: idle state, vacant state, and specific vacant state. It should be noted that the term "property" here includes not only properties where people reside, but also properties used by people for business purposes, for example.

[0012] In other words, in this embodiment, the types of properties include, for example, single-family homes and apartment buildings, as well as factories, warehouses, shops in shopping districts, or lodging facilities. When a single-family home or apartment building is given as an example of a property type, the user is, for example, a resident. On the other hand, when a factory is given as an example of a property type, the user is, for example, at least one of the factory's owner and employees. When a warehouse is given as an example of a property type, the user is, for example, at least one of the warehouse's owner or manager and workers. In this embodiment, when an apartment building is given as an example of a property type, a vacant state (and a specific vacant state) refers to a state in which the residents of all households constituting the apartment building do not reside there on a daily basis.

[0013] Figure 1 is a system configuration diagram showing an example of the configuration of the property status determination system 1 according to the first embodiment.

[0014] The property status determination system 1 comprises a power usage database 200, a property appearance database 150, a data input unit 100, and a specific status determination unit 300, and preferably includes a property type determination unit 30 and a property management database 400.

[0015] The electricity usage database 200 manages information on the electricity usage of each target property for a large number of properties located in a predetermined area, such as a city, town, or country. The electricity usage database 200 includes, for example, the address and user of each target property, as well as electricity supply data indicating the amount of electricity supplied to each target property, and location information including the address or latitude and longitude of the power receiving point of each target property. The electricity supply data for each target property manages the amount of electricity supplied by time period, for example, and includes the location information of the target property. The location information of the target property may be, for example, a supply point identification number, as described later. The electricity supply data includes, for example, the amount of electricity supplied to each piece of equipment at the power receiving point.

[0016] The data input unit 100 has a function of receiving appearance image data including the features of the appearance image of the target property. The data input unit 100 writes and stores the appearance image data acquired from the outside into the property appearance database 150 for each piece of position information such as the address of the shooting location included in the appearance image data, for example. The shooting location referred to here corresponds to the address of the target property of the appearance image based on the appearance image data.

[0017] The property appearance database 150 is an example of an appearance image data storage unit, and stores appearance image data including the features of the appearance images of a number of properties including the target property.

[0018] The property appearance database 150 stores, for example, appearance image data including the features of the appearance images of a number of properties existing in a predetermined area. The appearance image data may be prepared in advance, or may be constantly acquired by a monitoring device such as a vehicle's drive recorder, for example. The property appearance database 150 manages the appearance image data of each property. Note that if the appearance image data is acquired and used in real time, the property appearance database 150 may be omitted.

[0019] The property type determination unit 30 performs, for example, image analysis processing using an image recognition function on the appearance image based on the appearance image data, and determines the type of the target property included in the appearance image. The property type determination unit 30 compares the position information of the target property included in the appearance image data with the position information of the target property included in the power supply amount data.

[0020] The specific state determination unit 300 determines, with respect to the target property, based on the power supply amount data thereof, whether the target property is in a first state where it is not used daily or in a second state where it is used daily.

[0021] The specific state determination unit 300 includes a dormant state determination unit 21 and a vacant house state determination unit 32. When the dormant state determination unit 21 determines that the supplied power to the target property is standby power below a predetermined threshold based on the power supply amount data, it determines whether the target property corresponds to a dormant state in which there is still a possibility of being used daily in the future among the above first states.

[0022] When the vacant house state determination unit 32 determines that the target property does not correspond to the dormant state among the first states by the dormant state determination unit 31 (for example, the vacant house state or the specific vacant house state), it determines from the external appearance image based on the external appearance image data whether the target property corresponds to a specific vacant house state that may affect the surrounding of the target property or a vacant house state that has no possibility of affecting the surrounding of the target property. The vacant house state determination unit 32 may determine whether the target property corresponds to the specific vacant or state or the vacant house state according to whether a power supply contract has been concluded with the target property.

[0023] More specifically, when the vacant house state determination unit 32 determines that the target property does not correspond to the dormant state among the first states by the dormant state determination unit 31, for example, it determines whether the target property corresponds to the specific vacant house state or the vacant house state according to whether it satisfies the specific vacant house state determination conditions described later, that is, for example, whether it satisfies the specific vacant house state determination conditions considering the external appearance features based on the external appearance image data.

[0024] The property management database 400 manages, for each property ID for distinguishing a plurality of properties from each other, as property information regarding the plurality of properties, the type of the property, the location information of the property, the identification information for distinguishing the power receiving points of the plurality of properties from each other, the external appearance image data, the features of the external appearance, and the state of the property. By doing so, the property information regarding the plurality of properties can be accumulated, and the specific state determination unit 300 can determine the state of the property using the accumulated property information.

[0025] The property management database 400 has various tables that manage information about numerous properties (hereinafter referred to as "property information"). The tables of the property management database 400 will be described later.

[0026] Figure 2 shows an example of the configuration of the property information table 41 of the property management database 400 shown in Figure 1. The property management database 400 manages property information for multiple properties, with each property ID (IDentifier) ​​used to identify multiple properties from one another.

[0027] The property information table 41 manages the property type, property location information, supply point identification number, exterior image data, exterior characteristics, and property status for each property ID, and preferably also manages the risk of state transition. The property information table 41 manages the registration date and time for each property ID, and can also manage past information for each property ID.

[0028] The property location information includes the property's address and at least one of its latitude and longitude. The supply point identification number is identification information for distinguishing the power receiving points of multiple properties from each other. Note that the columns of the illustrated property information table 41 are just an example, and the property information table 41 may be configured to manage columns for other information as needed.

[0029] The property type is as described above, so the explanation is omitted. The property address is the property's location information. The property's latitude and longitude are also the property's location information. The property's location information only needs to include either the property's address or its latitude and longitude. The supply point identification number is an identification number used to distinguish between multiple power receiving points. The exterior image data is as described above, so the explanation is omitted. The exterior features indicate the visual characteristics of the property as seen from the outside, extracted from the exterior image data.

[0030] The state of a property includes, for example, a first state where it is not used on a daily basis, and a second state where it is used on a daily basis. The first state includes, for example, idle state, vacant state, and specific vacant state. The second state indicates the occupied state if the property is a residential property such as a detached house. The first state is, as described above, a state where it is not used on a daily basis, and for example, if the property is a residential property such as a detached house, it indicates an unoccupied state. In this embodiment, residential properties include detached houses and apartment buildings. State transition risk manages future risks according to what state the property may transition to in the future, even if it is currently in the above state.

[0031] The state transition risk can be set using a three-level evaluation system, for example, "high," which indicates that the property may be affected by the surrounding area in the future; "medium," which indicates that the property will not be affected by the surrounding area in the future, but that attention should be paid to its future state; or "low," which indicates that the property is highly unlikely to be affected by the surrounding area in the future. The state transition risk is set, for example, by the vacant house state determination unit 32 of the specific state determination unit 300.

[0032] The property status determination system 1 according to this embodiment has the configuration described above, and next, an example of a property status determination method using the property status determination system 1 will be described. The property status determination method includes: a specific status determination step in which a specific status determination unit 300 reads power supply amount data (so-called smart meter data) indicating the amount of power supplied to a property from a power usage database 200, which is an example of a power supply amount storage unit where power supply amount data (so-called smart meter data) is stored, and determines based on the power supply amount data whether the target property is in a first state where it is not used on a daily basis, or in a second state where it is used on a daily basis; an idle status determination step in which an idle status determination unit 21 determines, based on the power supply amount data, that the power supplied to the target property is standby power below a predetermined threshold, and determines that the target property is in an idle state among the first states where it may still be used on a daily basis in the future; and an idle status determination step in which a vacant house status determination unit 32 determines, based on an exterior image including the characteristics of the exterior image of the target property, whether the target property is in a specific vacant house state where it may affect the surrounding area, or in an idle house state where it does not affect the surrounding area.

[0033] Figure 3 is a flowchart showing an example of the procedure for determining the property type according to this embodiment. In step S1, the data input unit 100 stores the exterior image data of a property in the property exterior database 150 in association with that property each time it receives the image data. Alternatively, the data input unit 100 may directly hand over the exterior image data of a property to the property type determination unit 30 each time it receives the image data.

[0034] In step S2, the property type determination unit 30 reads exterior image data for the target property from the property exterior database 150, registers the exterior image data in the property information table 41 in association with the property ID of the target property, and determines the type of the target property based on the characteristics of the exterior image of the target property based on the exterior image data.

[0035] If the property type determination unit 30 infers from the exterior image that the target property is a residence (step S3), it identifies the target property as a residence and registers the property type as "residence" in the property information table 41, corresponding to the property ID of the target property (step S4). If the property type determination unit 30 infers from the exterior image that the target property is a factory (step S5), it identifies the target property as a factory and registers the property type as "factory" in the property information table 41, corresponding to the property ID of the target property (step S6).

[0036] If the property type determination unit 30 infers from the exterior image that the property is a warehouse (step S7), it identifies the property as a factory and registers the property type as "factory" in the property information table 41, associating it with the property ID of the property (step S8).

[0037] If the property type determination unit 30 infers from the exterior image that the target property is neither a residential property, a factory, nor a warehouse (step S9), or if it infers from the features of the exterior image that the target property is a general property such as a school or government building (step S9), it identifies the target property as a general property and registers the property type as "general property" in the property information table 41, associating it with the property ID of the target property (step S10), and terminates the property type determination process.

[0038] Figure 4 is a flowchart showing an example of the procedure for determining the property status in this embodiment. The property status determination process is performed by the property type determination unit 30. In this embodiment, the power supply amount data of the target property is stored in the power usage database 200 in association with the property ID of the target property each time it is received (step S11).

[0039] In step S12, the property type determination unit 30 links the exterior image data and power supply data of the same property based on location information (e.g., address, or latitude and longitude) that is managed in association with the exterior image data and power supply data (step S9).

[0040] In step S13, the property type determination unit 30 analyzes the power supply data of the target property and, for example, analyzes what kind of property the target property is based on the power supply data of the target property and its fluctuation patterns. The property type determination unit 30 may also analyze what kind of property the target property is according to the power supply contract with the target property.

[0041] In step S14, the property type determination unit 30 determines whether or not the specific vacant house condition determination conditions are met. Specifically, the property type determination unit 30 determines whether or not the specific vacant house condition determination conditions are met, taking into account, for example, the exterior characteristics based on exterior image data and the fact that the property has been without power for a predetermined number of consecutive days based on the analysis results thereof. If the specific vacant house condition determination conditions are met, the property type determination unit 30 determines that the property is in a specific vacant house state (step S15), while if the specific vacant house condition determination conditions are not met, it executes step S16.

[0042] In step S16, the property type determination unit 30 determines whether the property has been in a state of standby power only for a standard number of days. If the property has been in a state of standby power only for a standard number of days, the property type determination unit 30 determines that the property is idle (step S17). If the property has not been in a state of standby power only for a standard number of days, step S18 is executed. In step S18, the property type determination unit 30 determines that the property is vacant.

[0043] Next, in step S19, the property type determination unit 30 registers the above determination result as the property type in the property information table 41, associating it with the property ID.

[0044] Once the property type determination unit 30 registers the property information in the property information table 41 as described above, when it receives a request from an external source for the status of a property that has been specified as a target property, it searches the property information table 41 using the property ID of the target property as the search key, retrieves the status of the property corresponding to the property ID of the target property as the search key, and provides it to the external source. Alternatively, instead of registering the status of the property as an example of the determination result described above in the property information table 41 as described above, the property type determination unit 30 may directly provide the determination result to the external source. In this case, the property information table 41 may be omitted.

[0045] The property's condition, as an example of the assessment result, can be used, for example, by the local government where the property is located, as well as by non-life insurance companies.

[0046] As described above, the property status determination system 1 according to this embodiment includes: a data input unit 100 that receives exterior image data including the characteristics of the exterior image of the target property; a power usage database 200 as an example of a power supply amount storage unit where power supply amount data indicating the amount of power supplied to the property is stored; a specific status determination unit 300 that determines, based on the power supply amount data, whether the target property is in a first state where it is not used on a daily basis, or in a second state where it is used on a daily basis; an idle status determination unit 21 that determines, based on the power supply amount data, that the power supplied to the target property is standby power below a predetermined threshold, and that the target property falls under an idle state of the first state where it may still be used on a daily basis; and an idle status determination unit 32 that determines, based on the exterior image data, whether the target property falls under a specific vacant house state where it may affect the surrounding area, or a vacant house state where it does not affect the surrounding area.

[0047] With this configuration, it is possible to estimate the detailed condition of a property without actually sending investigators to the property site.

[0048] In the above embodiment, if the idle state determination unit 31 determines that the target property does not fall under the idle state among the first states, the vacant property status determination unit 32 determines, for example, whether the target property falls under the specific vacant property status or the vacant property status, depending on whether only standby power has been continuously consumed for at least a standard number of days. In this way, the idle state determination unit 21 can accurately determine whether the power supplied to the target property is standby power or not based on the power supply amount data, so the vacant property status determination unit 32 can accurately estimate whether the target property falls under either the specific vacant property status or the vacant property status.

[0049] The property status determination system 1 according to this embodiment includes a property management database 400 as an example of a property management unit. The property management database 400 manages property information for multiple properties, such as the type of property, location information of the property, identification information for identifying the power receiving points of multiple properties, exterior image data, exterior characteristics, and the status of the property, for each property ID used to distinguish multiple properties from one another. In this way, property information for multiple properties is accumulated, and the specific status determination unit 300 can estimate the status of a property using the accumulated property information.

[0050] (2) Second embodiment Since the property status determination system according to the second embodiment has almost the same configuration and operation as the property status determination system according to the first embodiment, the explanation of the similar configuration and operation will be omitted, and the following explanation will focus on the differences.

[0051] The property condition determination system according to the second embodiment is designed to handle cases where the target property is an apartment building inhabited by multiple households, in addition to the functions of the property condition determination system 1 according to the first embodiment.

[0052] The property type determination unit 30 may, as a result of image recognition processing based on the exterior image data of the target property, determine that, for example, if it determines that the windows of all households in an apartment building were dark for a certain period of time or longer at night, the target property, which is an apartment building, is in one of the first states (for example, idle, vacant, and specific vacant). In other words, the property type determination unit 30 distinguishes between single-family homes and apartment buildings as residential properties and determines the type of property.

[0053] According to the embodiments described above, even if the target property is not only a detached house but also an apartment building, the status of each household constituting the apartment building can be estimated, and the same effects as in the first embodiment can be achieved, for example, as with a detached house.

[0054] (3) Third Embodiment The property status determination system according to the third embodiment has almost the same configuration and operation as the property status determination system 1 according to the first embodiment and the property status determination system according to the second embodiment. Therefore, the explanation of the similar configuration and operation will be omitted, and the following explanation will focus on the differences.

[0055] The property status determination system according to this embodiment includes the property management database 400 described above. The property management database 400 has a property information table 41. The property information table 41 is an example of a past data management unit, and stores multiple past exterior image data used when the vacant property status determination unit 32 determines whether multiple properties are in a vacant state or a specific vacant state, in association with the determination results for multiple properties made by the vacant property status determination unit 32.

[0056] If the data input unit 100 is unable to receive exterior image data, the vacant property status determination unit 32 reuses past exterior image data of other properties similar to the target property and determines whether the target property is vacant or in a specific vacant property state based on past exterior image data.

[0057] In this way, even if exterior image data cannot be obtained for a particular property, the vacant property status determination unit 32 can estimate with approximately accuracy whether the property is vacant or in a specific vacant state based on past exterior images derived from past exterior image data of other properties similar to the property in question. In other words, even if exterior image data cannot be obtained for a particular property, the vacant property status determination unit 32 can estimate with approximately accuracy whether the property is vacant or in a specific vacant state based on past exterior images derived from past exterior image data of other properties similar to the property in question.

[0058] It should be noted that the present invention is not limited to the embodiments described above, but includes various modifications and equivalent configurations within the spirit of the attached claims. For example, the embodiments described above are described in detail for the purpose of clearly illustrating the present invention, and the present invention is not necessarily limited to having all the configurations described. Also, each element described in parallel in this embodiment may be configured such that at least one of the elements is connected in series with respect to the other elements.
