(Hardware configuration)
FIG. 1 shows a block diagram of an agricultural information processing device 100. The agricultural information processing device 100 includes a data reception section 101, an operation reception section 102, a histogram creation section 103, a screen display control section 104, a calibration curve creation section 105, a storage section 106, and a display 107. These functional units can also be understood as a processor that executes a corresponding function, an electronic circuit that executes a corresponding function, and a software program that executes a corresponding function.

Agricultural information processing device 100 can be configured with various processors. For example, the agricultural information processing device 100 is configured with an electronic circuit such as an ASIC (Application Specific Integrated Circuit) or a PLD (Programmable Logic Device) represented by an FPGA (Field Programmable Gate Array). It is also possible to configure some functions with dedicated hardware and configure other parts with a general-purpose microcomputer. In addition, the functional units shown in Figure 1 are installed on a general-purpose PC (personal computer), a computer for various types of control (for example, a computer for automatic steering control and automatic driving control of a tractor), and a server that can be connected via a communication line. It is also possible to install application software for realizing the functions described above and operate the computer as the agricultural information processing device 100.

Whether each functional unit is configured by dedicated hardware or by software by executing a program on a CPU is determined by taking into account the required calculation speed, cost, power consumption, etc.

In this example, a general-purpose PC is made to function as the agricultural information processing apparatus 100 by installing application software for implementing each functional unit shown in FIG. 1 into the PC. Examples of the PC to be used include a notebook computer and the like. It is also possible to use a user's PC as an interface and operate a server connectable to the PC via a line as the agricultural information processing device 100. In this case, various calculations (processing) are performed on the server side, and the PC is used as an operating terminal. It is also possible to use a smartphone as an operating terminal.

The data reception unit 101 receives distribution data indicating the distribution of the ability to grow crops or the distribution of the growth state of crops in the field.

The ability to grow crops in a field is determined by one or more combinations selected from soil nutrients (nitrogen, phosphoric acid, etc.), moisture content, electrical conductivity, pH, etc., or based on these factors. Examples include calculated parameters. For example, fertile soil has a relatively high ability to grow crops. Acquisition of information related to soil conditions includes detection of reflected light of a specific wavelength using various sensors and laser sensors (for example, detection of wavelengths specific to nitrogen), soil analysis using a spectrum camera, analysis of past growth history, etc. carried out by

Distribution data indicating the distribution of the ability to grow crops in a field refers to data that shows how the ability is distributed in the field. For example, Fig. 2(B) shows an example of distribution data showing the distribution of the ability to grow crops in a field, where the field is divided into a matrix shape vertically and horizontally, and the growth value level in the soil in each division (in this example, An example of map data is shown in which the value (nitrogen content) is mapped at five levels. FIG. 2(B) shows the distribution of soil growth ability in a field, and is an example of a soil map.

The growth value level in FIG. 2(B) is an example of an index indicating the ability to grow crops. In this example, the growth value level is a value that is calculated by predicting the nitrogen content of the soil from the nitrogen content of the leaves measured by a laser sensor.

The position on the map is measured by surveying using GNSS (Global Navigation Satellite System) or TS (Total Station). By acquiring the relationship between the measured value at this position and the ability to grow crops (e.g., nutrient content and concentration) at the relevant position, and mapping it as shown in Figure 2 (B), you can improve the ability of crops in the field. Distribution data showing the distribution of growth ability can be obtained.

The state of growth of crops in a field includes the state of growth of stems, leaves, flowers, fruits, etc. evaluated using sensors and the like. For example, evaluate one or more of stem length, leaf color (pigment content), flower color, fruit size, starch concentration, fruit sugar content, leaf and light transmittance, density, etc. The parameters determined are used as numerical representations of the growth status of crops. This technique is described in, for example, Japanese Patent Laid-Open No. 2012-247235.

Distribution data indicating the distribution of the growth state of crops in a field refers to data that shows how the growth state of crops (for example, sugar content of fruit) is distributed in the field. For example, in FIG. 2(B), by replacing the growth value level with a ranking of the sugar content of the fruit (for example, grapes), distribution data indicating the distribution of the growth state of the crop (grape) in the field can be obtained. This distribution data indicates the distribution of the degree of crop growth in the field, and is an example of a growth map.

The operation accepting unit 102 accepts operations by the user. In this example, the agricultural information processing apparatus 100 is composed of a PC, and the user operates the agricultural information processing apparatus 100 using the operation interface (GUI or keyboard input) of the PC. A portable information processing terminal such as a smartphone can also be used as the operation reception unit 102.

The histogram creation unit 103 plots the level of the ability to grow the crop or the growth state of the crop on the horizontal axis based on the distribution data indicating the distribution of the ability to grow the crop or the distribution of the growth state of the crop in the field. A histogram is created with the vertical axis representing the number or percentage of locations in the field where the level is the same.

Here, the values on the horizontal axis may be considered to be at the same level within a certain range. Alternatively, the field may be divided into a matrix, and the average value or center value of the level of growth ability or growth state of crops in each division may be adopted as the value in the division. The vertical axis of the histogram may be the number of sections, or may be a percentage of all sections.

An example of this histogram is shown in FIG. 2(A). In Figure 2 (A), the level of the growth value set in five stages is plotted on the horizontal axis, and the number of plots showing the corresponding growth value (level) (the number of plots set in the matrix shown in Figure 2 (B)). A histogram in which the vertical axis is the number) is shown.

The screen display control unit 104 receives the result of the user's operation on the operation reception unit 102 and highlights a position on the field map corresponding to the level of growth value selected by the user. An example of highlighted display will be described below.

2 to 4 are examples of UI (user interface) screens displayed on the display 107. FIG. 2 is a standard screen display. Note that FIG. 2(A) and FIG. 2(B) are displayed on the same screen. 2(A) and FIG. 2(B) may be made into separate screens so that they can be switched and displayed. These points also apply to FIGS. 3 and 4.

Here, it is assumed that the user performs an operation to select growth value level 5 in FIG. 2(A) using the GUI function of the PC being used. The content of this operation is accepted by the operation reception unit 102. When the above selection is made, the screen switches to the screen shown in FIG. 3. In FIG. 3(B), locations with a growth value of level 5 are highlighted on the field map. By displaying the screen shown in FIG. 3(B), the distribution of growth value level 5 in the field can be visually grasped.

Further, in FIG. 2(A), it is assumed that growth value level 1 is selected. In this case, the display switches to the one shown in FIG. 4, and a map screen (FIG. 4(B)) in which the distribution of growth value level 1 in the field is visually highlighted is displayed.

The screen display control unit 104 performs the process related to switching the display from FIG. 2 to FIG. 3 and the process related to switching the display from FIG. 2 to FIG. 4 by the user's operation. FIG. 2(A) also shows a graph of a calibration curve in which the level of growth value is plotted on the horizontal axis and the amount of fertilizer is plotted on the vertical axis. By selecting a specific value on the horizontal axis in this calibration curve graph (for example, by clicking the mouse), you can switch the display from Figure 2 to Figure 3, and from Figure 2 to Figure 4. You can also do it. Processing in this case is also performed by the screen display control unit 104.

The calibration curve creation unit 105 takes the level of the ability to grow the crop or the growth state of the crop (in the case of FIG. 2(A), the level of the growth value) on the horizontal axis illustrated in FIG. Create a graph of a calibration curve with the amount of fertilizer applied on the axis. Usually, a growth value is obtained by measurement using an optical sensor or the like, and the corresponding amount of fertilizer is input based on experience or past results. By doing this at two or more points and approximating it with a straight line, a metric curve is created. The horizontal axis of the calibration curve is not limited to the growth value (ability to grow crops), but can also use the level of the growth state of the crop (for example, fruit color, density, etc.).

The display 107 is a display device (such as a liquid crystal display device) of a terminal (such as a PC) used by a user. 2 to 4 are examples of UI (user interface) screens displayed on the display 107. The user performs various operations using the agricultural information processing device 100 using a GUI (graphical user interface) using the display 107 .

(Example of processing)
An example of the process will be described below. A program for performing this processing is stored in an appropriate storage area and executed by the agricultural information processing device 100. It is also possible to save this program on a server and download it from there to a PC functioning as the agricultural information processing device 100 via an Internet line or the like.

First, distribution data indicating the distribution of the ability to grow crops or the distribution of the growth state of crops in the field is received (step S101). This process is performed by the data reception unit 101. In this process, for example, the data shown in FIG. 2(B) is accepted. If this data is stored inside the agricultural information processing device 100, it is read out onto an appropriate storage area.

Next, based on the distribution data obtained in step S101 (for example, FIG. 2(B)), the ability to grow a crop or the level of the growth state of the crop (growth value in the case of FIG. 2) is plotted on the horizontal axis. A histogram is created with the vertical axis representing the ability to grow crops or the number or proportion of growth states of the crops (in the case of FIG. 2, the number of sections showing a specific growth value) (step S102). This process is performed by the histogram creation unit 103.

Next, an operation by the user is accepted (step S103). This process is performed by the operation reception unit 102. Then, based on the content of the received operation, the distribution data corresponding to the selected level (in the case of FIG. 2, the growth value level) is highlighted on the screen (step S104). This process is performed by the screen display control unit 104. Through this processing, for example, the screen displays shown in FIGS. 3 and 4 are performed.

Based on distribution data showing the distribution of the ability to grow crops or the growth state of crops in the field, the horizontal axis is the distribution of the ability to grow the crops or the level of the growth conditions of the crops, and the vertical axis is the amount of fertilizer applied. A calibration curve may also be created. For example, from the growth value distribution data in FIG. 2(B), a calibration curve shown in FIG. 2(A) can be obtained in which the horizontal axis represents the growth level and the vertical axis represents the amount of fertilizer applied. This process is performed by the calibration curve creation section 105.

(Other examples of display screens)
In FIG. 5, an example of a growth map synthesized and displayed on an aerial photograph image is shown on the right, and a histogram corresponding to the growth map is shown on the left (the horizontal axis represents the level (class) of the growth value, and the vertical axis represents the growth value level (class)). A histogram of growth values) is shown.

Here, if you select one or more levels (degrees of growth values) on the horizontal axis on the histogram in the above display screen (for example, by left-clicking the mouse), the corresponding position on the growth map on the right side will be highlighted. Is displayed. According to this function, it is possible to visually grasp the position of a particular growth level of interest on the left histogram on the right growth map.

Conversely, when a specific position on the growth map on the right side is specified (for example, specified by left-clicking the mouse), the corresponding level (position on the horizontal axis) on the histogram on the left side is highlighted. This makes it possible to know the growth value at a specific position on the growth map. You can also know the amount of fertilizer required for that location.

Figure 6 shows an example in which the horizontal axis of the histogram on the left is displayed in a color gradation on a screen display similar to that in Figure 5, and a color display corresponding to this gradation is displayed on the growth map on the right. . According to this aspect, the correspondence relationship between the histogram, in which the level (class) of the growth value is taken on the horizontal axis and the growth value is taken on the vertical axis, and the growth map synthesized with the aerial photograph image is expressed by color gradation display. A new UI (user interface) is obtained.
