[0012] (Embodiment 1)

[0013] A lodging determination system (1000) according to the present embodiment of the invention will be described with reference to the drawings. In the present embodiment, as shown in FIG. 1, the lodging determination system (1000) comprises a lodging determination device (100) and a terminal (200). The lodging determination device (100) is connected to a satellite image transmission device (40), a weather information transmission device (60), and a terminal (200) via a network (20), for example, the Internet.

[0014] The satellite image distribution device (40) distributes image information representing a satellite image of one or more packages (500) to the lodging determination device (100). The satellite image represents, for example, an image of an area containing the packages (500) captured from an artificial satellite (50). For example, the satellite image represents a synthetic aperture radar image (SAR image) of an area containing the packages (500).

[0015] The lodging determination device (100) determines whether the cultivated crops are lodging in the field (500) based on satellite images. For example, the lodging determination device (100) determines whether the crops in the field (500) are lodging by comparing the latest satellite image with a past satellite image. For example, the lodging determination device (100) compares a reference past satellite image (for example, a past satellite image captured at a time when the crops were not lodging) with the latest satellite image showing the lodging status at the current time. The lodging determination device (100) determines whether the crops in the field (500) are lodging based on the comparison result. The lodging determination device (100) outputs display information to a terminal (200) that distinguishes between the field (500) where the crops are lodging and the field (500) at the end thereof.

[0016] The terminal (200) displays information and notifies the user whether the crops in the packaging (500) are lodging. For example, as shown in FIG. 2, the terminal (200) identifiablely displays a first packaging (500-1) in which the crops are lodging and a second packaging (500-2) in which the crops are not lodging on a map. By doing so, the user can easily identify the packaging (500) in which the crops are lodging.

[0017] Additionally, the weather information distribution device (60) outputs weather information, such as wind speed, in the area including the field (500) to the lodging determination device (100). As shown in FIG. 3, the lodging determination system (1000) may display a captured time image (610) showing the time when the satellite image was captured and weather information (e.g., wind speed) at each time, and may allow the user to select a satellite image to be compared with the most recently captured satellite image. The lodging determination system (1000) may not be able to determine that the crop in the field (500) is lodging when the crop in the field (500) is lodging in both of the two satellite images being compared. For this reason, in the example shown in FIG. 3, if the crops were lodging on February 11, there may be cases where the field (500) where the crops are lodging cannot be extracted even when comparing the satellite image of February 13 with the satellite image of February 12. For this reason, the user may select the satellite image of February 10, where the crops are thought not to be lodging, as a comparison target.

[0018] (Composition of the uniform judgment system)

[0019] The configuration of the uniform determination device (100) is described. As shown in FIG. 4, the uniform determination device (100) is equipped with an input / output device (110), a computation device (120), a communication device (130), and a memory device (140). The uniform determination device (100) is a computer, for example, including a cloud server. Information for the computation device (120) to perform processing is input to the input / output device (110). Additionally, the input / output device (110) outputs the result of the computation device (120) performing the processing. The input / output device (110) includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, touch panel, etc. The input / output device (110) may be omitted.

[0020] A communication device (130) is connected to a network (20) and communicates with each device through the network (20). For example, the communication device (130) transmits image information obtained from a satellite image distribution device (40) to a computing device (120). Additionally, it transmits a signal generated by the computing device (120) to a terminal (200). Furthermore, the communication device (130) may obtain information from another device that is not connected through the network (20). For example, the communication device (130) may obtain information from another device through any storage medium, such as a memory card or a USB (Universal Serial Bus) memory. Additionally, the communication device (130) may obtain information from another device directly connected via USB, etc. The communication device (130) includes various interfaces, such as a NIC (Network Interface Card) or a USB terminal.

[0021] The memory device (140) stores various data for determining the lodging status of crops in the packaging (500), such as packaging data (410), satellite image data (420), and a lodging determination program (430). The memory device (140) is used as a non-transitory tangible storage medium for storing the lodging determination program (430). The lodging determination program (430) may be provided as a computer program product recorded on a computer-readable storage medium (1), or as a computer program product downloadable from a server.

[0022] Packaging data (410) stores information regarding one or more packaging (500). For example, packaging data (410) stores information indicating the geographical range and location of one or more packaging (500). For example, the geographical range of packaging (500) may be indicated by any method. For example, when packaging (500) is a polygon, the geographical range of packaging (500) may be indicated by the location of the vertices of the polygon (e.g., latitude and longitude) and a combination of adjacent vertices. Additionally, packaging data (410) may store information indicating the lodging state determined by the lodging determination device (100) in relation to the corresponding packaging (500). Packaging data (410) may also store information indicating the area of ​​one or more packaging (500).

[0023] The satellite image data (420) stores image information obtained from the satellite image distribution device (40). The image information represents one or more satellite images in relation to the time (e.g., time) when the satellite images were captured.

[0024] The computing device (120) reads and executes a lodging determination program (430) from the memory device (140) and performs various data processing to determine a field (500) in which crops are lodging. For example, the computing device (120) includes a central processing unit (CPU), etc.

[0025] The computing device (120) cooperates with the memory device (140) by reading and executing a lodging determination program (430), and realizes a data storage unit (150), a comparison information generation unit (160), a lodging determination unit (170), and an output unit (180) as shown in FIG. 5. The data storage unit (150) stores packaging data (410) and satellite image data (420). The comparison information generation unit (160) generates comparison information by comparing a satellite image captured at a first time and a satellite image captured at a second time. The lodging determination unit (170) determines the lodging state of the crop in the packaging (500) based on the comparison information. The output unit (180) outputs lodging information indicating the lodging state of the crop in the packaging (500) to the terminal (200).

[0026] Next, the configuration of the terminal (200) shown in FIG. 1 will be described. As shown in FIG. 6, the terminal (200) is equipped with an input / output device (210), a computing device (220), a communication device (230), and a memory device (240). The terminal (200) includes, for example, a computer, a tablet, a mobile phone, etc. Information for the computing device (220) to execute processing is input to the input / output device (210). Additionally, the input / output device (210) outputs the result of the processing executed by the computing device (220). The input / output device (210) includes various input and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, etc.

[0027] A communication device (230) is connected to a network (20) and communicates with each device through the network (20). For example, the communication device (230) transmits a signal obtained from a dobok judgment device (100) to a calculation device (220). Additionally, the communication device (230) transmits a signal generated by the calculation device (220) to the dobok judgment device (100). Furthermore, the communication device (230) may obtain information from another device that is not connected through the network (20). For example, the communication device (230) may obtain information from another device through any storage medium, such as a memory card or a USB (Universal Serial Bus) memory. Additionally, the communication device (230) may obtain information from another device directly connected to a USB terminal, etc. The communication device (230) includes various interfaces such as a transceiver, a NIC (Network Interface Card), and a USB terminal, which are used for wireless communication, such as a wireless LAN (Local Area Network) or a cellular network.

[0028] The memory device (240) stores various data, such as a display program (440), for displaying uniform information obtained from the uniform judgment device (100). The memory device (240) is used as a non-transitory tangible storage medium for storing the display program (440). The display program (440) may be provided as a computer program product recorded on a computer-readable storage medium (2), or as a computer program product downloadable from a server.

[0029] The arithmetic unit (220) reads and executes a display program (440) from a memory unit (240) and performs various data processing to display the dodging information. For example, the arithmetic unit (220) includes a central processing unit (CPU), etc.

[0030] The computing device (220) cooperates with the memory device (240) and the input / output device (210) by reading and executing the display program (440), and realizes the display unit (250) as shown in FIG. 5. The display unit (250) displays the uniform information obtained from the uniform determination device (100).

[0031] (Operation of the uniform judgment system)

[0032] The operation of the uniform determination system (1000) is described. First, the operation of the uniform determination system (1000) acquiring a satellite image is described. For example, when a predetermined time (e.g., every hour) is reached, the computing unit (120) of the uniform determination device (100) executes the uniform determination program (430) and initiates processing that is part of the uniform determination method. For example, when a predetermined time is reached, the data storage unit (150) realized by the computing unit (120) acquires image information representing a satellite image captured by an artificial satellite (50) from the satellite image distribution device (40) shown in FIG. 1. The data storage unit (150) stores the acquired image information in the satellite image data (420). In this way, the uniform determination system (1000) acquires the latest satellite image from the satellite image distribution device (40). The data memory unit (150) may acquire only the satellite image of the area containing the packaging (500) shown in the packaging data (410).

[0033] Next, the lodging determination system (1000) explains the operation of determining the lodging state of a crop in a field (500). For example, a user inputs an operation to display the lodging state of a crop in a field (500) to the input / output device (210) of the terminal (200). When the operation is input to the input / output device (210), the computing device (220) of the terminal (200) reads and executes a display program (440) from the memory device (240) and initiates the processing shown in FIG. 7, which is part of the lodging determination method.

[0034] Initially, in step S110, the display unit (250) realized by the computing device (220) requests the capture time information indicating the time when the satellite image was captured from the dobok judgment device (100).

[0035] Next, in step S120, the data storage unit (150) of the lodging determination device (100) outputs imaging time information indicating the time when the satellite image was captured to the terminal (200). For example, the data storage unit (150) obtains weather information (for example, information indicating wind speed) for each time period in a region including the geographical range of the packaging (500) from the weather information distribution device (60). In addition, the data storage unit (150) extracts imaging times indicating the time when a plurality of satellite images stored in the satellite image data (420) were captured. The data storage unit (150) outputs the extracted imaging times and imaging time information indicating the weather information for each time period to the terminal (200).

[0036] Next, in step S130, the display unit (250) of the terminal (200) receives reference information indicating the time when a reference past satellite image was captured in order to determine the lodging status of the crop in the packaging (500). For example, the display unit (250) displays a time when the satellite image was captured and a time when weather information at each time was captured, as shown in FIG. 3, based on the time when the satellite image was captured and the time when the reference past satellite image was captured, based on the time when the satellite image was captured obtained from the lodging determination device (100). The user selects the time when the reference past satellite image was captured from the displayed time when the satellite image was captured.

[0037] In the example shown in Fig. 3, the "satellite image" indicates that satellite images were captured on February 13, February 12, February 10, and February 9, marked with "○", and that no satellite image was captured on February 11, marked with "―". Therefore, the most recent satellite image was captured on February 13. Meanwhile, the example shown in Fig. 3 shows weather information, indicating that the wind speed on February 13 was 1.8 m / s, the wind speed on February 12 was 11.2 m / s, and the wind speed on February 11 was 10.3 m / s. Additionally, the wind speed on February 10 was 5.2 m / s, and the wind speed on February 9 was 0.8 m / s.

[0038] For example, although the satellite image was captured on February 12, since the wind speed has exceeded 10 m / s per second since February 11, there is a possibility that the crops in the field (500) have fallen over on February 12. For this reason, the user selects the satellite image of February 10, which is thought to be the date when the crops in the field (500) have not fallen over. For example, the user inputs an operation to the input / output device (210) to specify the time when the selected satellite image was captured. For example, the user inputs an operation to the input / output device (210) to select a shape (611) indicating that the satellite image was captured on February 10.

[0039] When the display unit (250) receives an operation to select a satellite image by a user, it determines that it has received reference information indicating the selected time. For example, when the user selects a shape (611), the display unit (250) determines that it has received reference information indicating February 10. The display unit (250) outputs the received reference information to the uniform determination device (100).

[0040] Furthermore, in step S140 shown in FIG. 7, the comparison information generation unit (160) of the lodging determination device (100) generates comparison information by comparing a past satellite image captured at the time indicated in the reference information with a latest satellite image. For example, the comparison information represents an interference synthetic aperture radar image (interference SAR image) of a SAR image corresponding to a past satellite image and a SAR image corresponding to a latest satellite image.

[0041] As shown in FIG. 8, the SAR image is formed by irradiating electromagnetic waves, such as microwaves, from a satellite (50) toward the ground as a transmitted wave (700), and by the received wave (701) that is scattered on the ground and returns to the satellite (50). For example, the transmitted wave (700) is scattered on the surface of a crop (550) and returns to the satellite (50) as a received wave (701). Meanwhile, the interference SAR image represents the difference height (710), which is the difference in height of the transmitted wave (700) scattered based on the difference in the received wave (701) between two different times, for example, a first time and a second time, for example, a phase difference. For example, in the interference SAR image, the location where the transmitted wave (700) is scattered (for example, latitude and longitude) is represented by the pixel position, and the difference height (710) is represented by the luminance value. For example, the difference height (710) represents the height of the crop when the latest satellite image is taken, relative to the height of the crop when the past satellite image was taken.

[0042] For example, the comparison information generation unit (160) generates an interference SAR image as comparison information, for example, showing the difference height (710) at each location of the packaging (500).

[0043] Next, in step S150 shown in FIG. 7, the lodging judgment unit (170) calculates statistical values ​​of comparison information, for example, difference height (710), in the packaging (500). For example, the lodging judgment unit (170) extracts difference heights (710) at one or more locations included in the packaging (500). The lodging judgment unit (170) calculates statistical values ​​of the extracted difference heights (710), for example, average value, median value, etc.

[0044] Continuing, in step S160, the lodging determination unit (170) determines the lodging state of the field (500) based on the statistical value of the comparative information in the field (500). For example, when the statistical value of the comparative information indicates that the height in the second period when the latest satellite image was captured is lower than the height in the first period when the past satellite image was captured by more than the difference threshold, the lodging determination unit (170) determines that the crop in the corresponding field (500) is lodging. Here, the difference threshold represents a preset arbitrary value. When the statistical value of the comparative information indicates that the height in the second period is not lower than the height in the first period by more than the difference threshold, the lodging determination unit (170) determines that the crop in the corresponding field (500) is not lodging.

[0045] For example, when the difference threshold is "0", the lodging determination unit (170) determines that the crop in the field (500) is lodging when the height of the field (500) in the second period is less than or equal to the height of the field (500) in the first period. When the difference threshold is "10 cm", the lodging determination unit (170) determines that the crop in the field (500) is lodging when the height of the field (500) in the second period is 10 cm or lower than the height of the field (500) in the first period. When the difference threshold is "-1 cm", the lodging determination unit (170) determines that the crop in the field (500) is lodging when the height of the field (500) in the second period is lower than the height of the field (500) in the first period made 1 cm higher.

[0046] For example, as shown in FIG. 8, the comparison information represents the difference height (710) of the height in the first period relative to the height in the second period (for example, the value obtained by subtracting the height in the second period from the height in the first period). In this case, when the statistical value of the difference height (710) in the packaging (500) is greater than or equal to the difference threshold, the lodging determination unit (170) determines that the crop in the corresponding packaging (500) is lodging.

[0047] For example, the uniform determination unit (170) determines the uniform status for each package (500) stored in the package data (410).

[0048] Next, in step S170 shown in FIG. 7, the output unit (180) outputs lodging information indicating the lodging status of the field (500) to the terminal (200). For example, the lodging information distinguishes between the field (500) where the crop has lodging and the field (500) where the crop has not lodging. The lodging information may also display an image on a map that identifiablely shows the location of the field (500) where the crop has lodging and the location of the field (500) where the crop has not lodging.

[0049] Furthermore, in step S180 shown in FIG. 7, the display unit (250) of the terminal (200) displays lodging information obtained from the lodging determination device (100). For example, the display unit (250) displays a display image (600) that identifiablely shows the geographical range of the first field (500-1) where the crop is lodging and the geographical range of the second field (500-2) where the crop is not lodging on a map, as shown in FIG. 2. For example, in the display image (600), the geographical range of the first field (500-1) is displayed in a display form different from the display form (e.g., color, shape, type of frame line, etc.) that shows the geographical range of the second field (500-2). The user can easily identify the field (500) where the crop is lodging by checking the display image (600) displayed on the input / output device (210) of the terminal (200).

[0050] (Variation Example)

[0051] The embodiments and variations described above are examples, and the configurations described in each embodiment and variation may be arbitrarily changed and / or combined arbitrarily to the extent that the function is not impaired. Furthermore, if the necessary function can be realized, some of the functions described in the embodiments and variations may be omitted.

[0052] For example, in step S160 shown in FIG. 7, the lodging determination unit (170) of the lodging determination device (100) has been shown to determine the lodging state of the crop in the field (500) by using statistical values ​​of the difference height (710) in the field (500), but is not limited thereto. For example, the lodging determination unit (170) may determine the lodging state in the field (500) by using the ratio of the area in the field (500) that indicates that the height in the second time period is lower than the difference threshold compared to the height in the first time period. For example, the lodging determination unit (170) calculates the lodging area in the field (500) that indicates that the height in the second time period is lower than the difference threshold compared to the height in the first time period. When the ratio of the lodging area to the area of ​​the packaging (500) is greater than the ratio threshold, the lodging determination unit (170) determines that the crops in the packaging (500) are lodging. Here, the ratio threshold represents a preset fixed value.

[0053] Here, the lodging determination unit (170) may determine the ratio of the lodging area to the area of ​​the pavement (500) by using the number of locations within the pavement (500) where the difference height (710) is measured by the interference synthetic aperture radar. For example, the lodging determination unit (170) determines the total number of measurement locations that are included within the geographical range of the pavement (500) among the measurement locations where the difference height (710) is measured by the interference synthetic aperture radar. Subsequently, the lodging determination unit (170) determines the number of measurement locations within the geographical range of the pavement (500) where the height at the second time is lower than the difference threshold relative to the height at the first time as the lodging number. The lodging determination unit (170) may determine the ratio of the lodging number to the total number as the ratio of the lodging area to the area of ​​the pavement (500).

[0054] Additionally, as shown in FIG. 9, the lodging determination unit (170) may determine the lodging state of the crop for each of the multiple sub-regions (510) that divide the packaging (500). For example, the lodging determination unit (170) calculates a statistical value of the difference height (710) in the sub-region (510) and determines the lodging state of the crop in the sub-region (510) by comparing the calculated statistical value of the difference height (710) with the difference threshold. The lodging determination unit (170) may determine the lodging state of the sub-region (510) by using the ratio of the quantity of measurement locations where the difference height (710) within the sub-region (510) is measured and the quantity of measurement locations within the sub-region (510) where the height at the second time is lower than the difference threshold relative to the height at the first time.

[0055] Additionally, the lodging determination unit (170) may determine the lodging state of the field (500) by using the ratio of the amount of crops lodging in the small area (510) to the amount of small area (510) within the field (500), as the ratio of the lodging area to the area of ​​the field (500).

[0056] When determining the lodging state of the crop in the small area (510), in step S170 shown in FIG. 7, the lodging information output by the output unit (180) may indicate the lodging state in the small area (510). In this case, the display unit (250) of the terminal (200) may display an image that identifiablely shows the first small area (510-1) where the crop is lodging and the second small area (510-2) where the crop is not lodging, as shown in FIG. 9.

[0057] In addition, the small area (510) is not limited to a rectangle as shown in FIG. 9 and may have any shape.

[0058] In step S130 shown in FIG. 7, the display unit (250) of the terminal (200) may display weather information other than the wind speed shown in FIG. 3 in relation to the time when the satellite image was captured. For example, the display unit (250) may display information indicating whether the area containing the pavement (500) is included in the strong wind zone of a typhoon. Additionally, the display unit (250) may display information indicating the distance from the area containing the pavement (500) to the strong wind zone of a typhoon. The display unit (250) may display two or more pieces of information, for example, wind speed and information indicating whether the area containing the pavement (500) is included in the strong wind zone of a typhoon. Additionally, the display unit (250) may not display weather information.

[0059] In step S140 shown in FIG. 7, an example is shown in which a past satellite image is selected by the user, but the satellite image to be compared may be selected automatically. For example, the lodging judgment unit (170) of the lodging judgment device (100) may select two recent satellite images and determine the lodging status of the packaging (500) based on the comparison information of the two satellite images. Additionally, the lodging judgment unit (170) may select a past satellite image based on weather information. For example, the lodging judgment unit (170) may determine the latest time when the wind speed exceeds a predetermined value, for example, 10 m per second, and determine the satellite image captured immediately before the determined time as the past satellite image. For example, the lodging judgment unit (170) may extract a time when the wind speed immediately after the time when the wind speed is below a predetermined value exceeds a predetermined value, and determine the satellite image captured immediately before the latest time among the extracted times as the past satellite image.

[0060] Additionally, although the lodging determination unit (170) has shown an example of comparing the latest satellite image with a past satellite image, it may use a satellite image other than the latest satellite image. For example, in step S120, the user may select two satellite images to compare. Additionally, the lodging determination unit (170) may select two satellite images to compare. When the lodging determination unit (170) selects two satellite images to compare, it determines the latest time when the wind speed has become a predetermined value, for example, 10 m per second or less, and determines the satellite image captured immediately after the determined time as the satellite image when the crop is lodging. For example, the lodging determination unit (170) extracts a time when the wind speed immediately before the time when the wind speed is below a predetermined value exceeds the predetermined wind speed, and determines the satellite image captured immediately after the latest time among the extracted times as the satellite image when the crop is lodging.

[0061] In step S170 shown in FIG. 7, the display unit (250) of the terminal (200) may display information indicating a field (500) in which crops have fallen over in any format. For example, the display unit (250) may display an image in a table format showing a first field (500-1) in which crops have fallen over and a second field (500-2) in which crops have not fallen over. Additionally, the display unit (250) may display an image showing only the first field (500-1) in which crops have fallen over.

[0062] For example, the terminal (200) may execute part or all processing of the uniform judgment device (100). Additionally, the uniform judgment device (100) may execute part or all processing of the terminal (200).

[0063] Additionally, the uniform judgment system (1000) may not include a terminal (200), and may obtain reference information from an external terminal not included in the uniform judgment system (1000), and may display uniform information on the external terminal.

[0064] The uniform judgment program (430) may include a display program (440).
