  Managing crops, especially fruit and vegetables, often depends on the experience and intuition of the producer. Moreover, when measuring the ripeness of a fruit, if a fruit is damaged, there exists a possibility of reducing a commercial value. Therefore, it is required to easily manage the growth of crops without damaging the fruits.

  In the technique of Patent Document 1, the growth and maturity of a fruit are determined based on the state of a branch on which the fruit hangs, the change in the color of the fruit, the amount of light transmitted, and the like. However, with this determination method, there is a possibility that the fruit growth status cannot be determined with high accuracy. In the technique of Patent Document 1, for example, there is a possibility that the estimation accuracy of sugar content, which is an index of the fruit growth status, is lowered. This is because fruits such as tomatoes differ in sugar content depending on the cultivation season, harvest time, and cultivation place. Therefore, in the technique of Patent Document 1, there is a possibility that the growth situation including the sugar content and the fruit growth situation estimated from the sugar content cannot be determined with high accuracy.

  Moreover, in the technique of patent document 2, the test paper which detects volatile gas is stuck on a fruit. Therefore, in the technique of Patent Document 2, it takes time to paste the inspection paper. Moreover, in the technique of patent document 2, there exists a possibility of giving damage to a fruit by sticking a test paper.

  In the technique of Patent Document 3, a fruit is hit with a hammer for impact, so that there is a high possibility that the fruit will be seriously damaged.

  Therefore, the techniques of Patent Documents 1 to 3 have a problem that the growth of fruits and vegetables cannot be managed with high accuracy in a non-contact manner without damaging the fruits.

  The present invention has been made in view of the above problems, and its purpose is to provide a technique capable of managing the growth of fruit and vegetable fruits in a non-contact manner and with higher accuracy without damaging the fruits. It is to provide.

  An information processing apparatus according to an aspect of the present invention includes an extraction unit that extracts information indicating a diameter and a height of the fruit from a photographed image of the fruit, and information indicating the diameter and the height of the extracted fruit. And calculating means for calculating the ratio between the diameter and the height, and determining means for determining the growth status of the fruit based on the calculated ratio.

  The growth status determination method according to one aspect of the present invention extracts information indicating the diameter and height of the fruit from a captured image obtained by capturing the fruit, and is based on information indicating the diameter and height of the extracted fruit. Then, the ratio between the diameter and the height is calculated, and the growth status of the fruit is determined based on the calculated ratio.

  Note that a computer program that implements each of the above apparatuses or methods by a computer and a computer-readable storage medium that stores the computer program are also included in the scope of the present invention.

  According to the present invention, the growth of fruits and vegetables can be managed with higher accuracy in a non-contact manner without damaging the fruits.

  The input device 110 is a device having a function capable of capturing information indicating the size of fruit and vegetables that are crops of the crop, in particular, the fruit and vegetable fruits (fruit 10 in FIG. 2). The input device 110 can be realized by an imaging device such as a camera, for example. The imaging device may be a commercially available web camera, for example. Note that the input device 110 is not limited to this, and any device can be used as long as the user can directly input an image including fruits and vegetables. Examples of the device capable of inputting an image including fruit vegetables include a reading device for an electronic storage medium such as a semiconductor memory reading device, an optical disk reading device, a magnetic disk reading device, and a magnetic tape reading device.

In addition, the device capable of inputting an image including fruit vegetables may be, for example, a device such as an Internet web service or a mail service via a communication unit. The input device 110 may be a device that can directly input information (for example, a numerical value) indicating the size of the fruit 10. Here, it is assumed that the information indicating the size of the fruit 10 is data indicating the diameter and height of the fruit 10. The diameter of the fruit 10 is the major axis of the fruit. Further, the height of the fruit 10 is assumed to be a length calculated from a perpendicular line from the fruit to the fruit in the region of the image showing the fruit. Hereinafter, data captured by the input device 110 is referred to as input data.

  The input device 110 transmits input data to the information processing device 100. In the present embodiment, the input device 110 is assumed to be a camera, and the input data is assumed to be image data indicating a captured image taken by the camera. Note that the time interval at which the input device 110 captures a captured image is not particularly limited. In the present embodiment, it is assumed that the camera captures fruits and vegetables on which the fruit 10 is grown so that at least one fruit 10 is included in one image. In this embodiment, the camera is fixedly installed, but may be movably installed. In FIG. 2, only one fruit 10 is shown for convenience of explanation, but there may be a plurality of fruits 10. Further, in the present embodiment, as shown in FIG. 2, the description will be made assuming that the plant body from which the fruit 10 is grown is one, but there may be a plurality of plant bodies from which the fruit 10 is grown.

  The display device 120 has a function of displaying output data output from the information processing device 100 on a screen. The contents displayed on the screen by the display device 120 will be described later.

  The storage device 130 stores data calculated by the information processing device 100 described later. The storage device 130 may store image data transmitted from the input device 110 to the information processing device 100.

  Note that in this embodiment, the input device 110, the display device 120, and the storage device 130 are described as separate components from the information processing device 100, but the present invention is not limited to this. The information processing device 100, the input device 110, the display device 120, and the storage device 130 may be integrally formed. For example, a notebook personal computer, a tablet terminal device, and a mobile terminal device are integrated with these devices.

(Information processing apparatus 100)
Next, the configuration of the information processing apparatus 100 of the growth management system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram showing an example of a functional configuration of the information processing apparatus 100 of the growth management system 1 according to the present embodiment. As illustrated in FIG. 1, the information processing apparatus 100 according to the present embodiment includes an extraction unit 102, a calculation unit 103, and a determination unit 104.

  The extraction unit 102 receives image data transmitted from the input device 110. The extraction unit 102 extracts information indicating the diameter and height of the fruit 10 from the image (captured image) indicated by the received image data. For example, the extraction unit 102 extracts the area of the fruit 10 included in the image indicated by the image data using image analysis software, and obtains information indicating the diameter and height of the fruit 10 from the extracted area. .

  When the information indicating the diameter and height of the fruit 10 taken in by the input device 110 is directly input, the extraction unit 102 may use this information as it is as the obtained information. Here, the information indicating the diameter and the height is a value indicating the diameter and a value indicating the height. These values may be absolute values or relative values. In the case of an absolute value, the extraction unit 102 receives information that can specify the size of the fruit 10 from the input device 110 together with the image data, such as the distance from the fruit 10 and the position where the input device 110 captures the fruit 10. . And the extraction part 102 may obtain | require the absolute value of the diameter and height of the fruit 10 based on this received information.

  The extraction unit 102 may store the diameter and height values in the storage device 130. As a result, the information processing apparatus 100 can analyze the data stored in the storage device 130 and use it for growth prediction, which will be described later. Further, the extraction unit 102 reads the image data stored in the storage device 130 instead of the data received directly from the input device 110, and then extracts the region of the fruit 10 in the image indicated by the read image data. May be.

  The extraction unit 102 supplies information indicating the obtained diameter and height to the calculation unit 103. In addition, the extraction part 102 calculates | requires the information which shows a diameter and height for every fruit 10, when the fruit 10 contained in one image is multiple, The information which shows this calculated | required diameter and height is obtained. Together with the information for identifying each, it is supplied to the calculation unit 103.

  The extraction unit 102 extracts information about the fruit 10 such as the pixel distribution (the color of the fruit 10) and the size of the fruit 10 from the area within the extracted image of the fruit 10. The information may be stored in the storage device 130.

  The calculation unit 103 receives information indicating the diameter and height of the fruit 10 from the extraction unit 102. And the calculation part 103 calculates the ratio of the diameter and height of this fruit 10 for every fruit 10. FIG. In the present embodiment, the calculation unit 103 is described as calculating the ratio of the diameter to the height (diameter / height), but the height relative to the diameter may be obtained.

  The calculation unit 103 supplies the calculated ratio to the determination unit 104. In addition, when the some fruit 10 is contained in an image, the calculation part 103 outputs the ratio calculated with respect to this fruit 10 with the information which identifies the fruit 10 to the determination part 104. FIG. When a plurality of plant bodies are included in the image, the calculation unit 103 may further output the calculated ratio to the determination unit 104 for each plant body.

  The determination unit 104 receives the ratio between the diameter and the height from the calculation unit 103. The determination unit 104 determines the growth status of the fruit 10 associated with the ratio from the received ratio. In this Embodiment, the determination part 104 shall determine the sugar content of the fruit 10 as a growth condition.

  Here, the correlation between the sugar content of fruits and vegetables and the ratio between the diameter and height of the fruits will be described with reference to FIG. Here, as an example of fruit vegetables, a tomato is taken as an example for explanation. FIG. 3 is a graph showing an example of sugar content of tomatoes relative to the ratio of diameter to tomato height. The horizontal axis of FIG. 3 shows the ratio of the diameter to the height of the tomato, and the vertical axis shows the concentration (%). In addition, the diameter of a tomato refers to the long diameter of a tomato, and height refers to the length of the perpendicular from a spatula.

As shown in FIG. 3, the ratio of diameter to height (diameter / height) and sugar content are in a substantially proportional relationship. When the horizontal axis is X, the vertical axis is Y, and the graph shown in FIG. 3 is regression-analyzed, the following equation (1) is obtained.
Y = 5.5897X-1.7033 (r ² = 0.3054) (1)
Here, r indicates a correlation coefficient.

  As shown in FIG. 3, it can be seen that there is a certain correlation between the sugar content of the fruit and the ratio between the diameter and the height. Thereby, the sugar content of this fruit can be estimated by using the ratio of the diameter and height of the fruit of fruits and vegetables. Therefore, it can be said that the determination unit 104 can determine the growth status of the fruit 10 based on the ratio between the diameter and the height of the fruit 10.

  The storage device 130 may store the above-described formula (1) and / or a graph as shown in FIG. In this case, the determination unit 104 refers to the storage device 130 to determine the growth status of the fruit 10. Further, the above equation (1) and / or the graph as shown in FIG. 3 may be stored in the determination unit 104.

  In addition, in this Embodiment, although the growth condition of the fruit 10 which the determination part 104 determines is demonstrated as sugar content as mentioned above, this Embodiment is not limited to this. The growth status of the fruit 10 may indicate the degree of fruit growth other than sugar content. Further, the growth status of the fruit 10 may indicate, for example, the nutritional state of the fruits and vegetables on which the fruit is grown, the harvest time, the fruit picking time, and the like. In addition, the growth status of the fruit may include information indicating the determination of fruit removal in the fruits and vegetables from which the fruit is grown. These can be determined from the sugar content of the fruit. The reason for this is that fruit vegetables have different sugar levels depending on the growth stage, accumulated temperature, accumulated solar radiation amount, and the like. Therefore, the normal value of sugar content is determined according to the growth situation. Therefore, the determination unit 104 can make these determinations by comparing the estimated (determined) sugar content with a predetermined sugar content. The predetermined sugar content may be stored in the storage device 130 or may be stored in the determination unit 104.

  Thus, the determination unit 104 may further determine the growth status of the fruit 10 associated with the sugar content based on the estimated (determined) sugar content. Furthermore, when the extraction unit 102 stores information about the fruit 10 such as the color of the fruit 10 and the size of the fruit 10 in the storage device 130, the determination unit 104 uses the information to determine the growth status of the fruit 10. You may judge. And the determination part 104 may include the information which shows the magnitude | size, hue, etc. of the fruit 10 in the determination result of the growth condition.

  The determination unit 104 outputs the determination result of the growth status of the fruit 10 to the display device 120. Note that the determination unit 104 may store the determination result of the growth status of the fruit 10 in the storage device 130. Thereby, the information processing apparatus 100 can manage the harvest time of the fruit 10 using the data (determination result of the growth state) accumulated in the storage device 130.

  The display device 120 displays the determination result of the growth status by the determination unit 104 on the screen. When the determination result of the growth status of the fruit 10 is the sugar content of the fruit 10, the display device 120 displays the sugar content of the fruit 10 at the time of photographing.

(Operation of the information processing apparatus 100)
Next, with reference to FIG. 4, the growth status determination process in the information processing apparatus 100 of the growth management system 1 according to the present embodiment will be described. FIG. 4 is a flowchart illustrating an example of the flow of the growth state determination process in the information processing apparatus 100 of the growth management system 1 according to the present embodiment.

  As shown in FIG. 4, first, the extraction unit 102 of the information processing apparatus 100 extracts information indicating the diameter and height of the fruit 10 from the image data sent from the input device 110 (step S41).

  Next, the calculation unit 103 calculates the ratio between the diameter and height of the fruit 10 (step S42).

  Subsequently, based on the ratio calculated by the calculation unit 103 in step S42, the determination unit 104 determines the growth status of the fruit 10 that is the calculation target of the ratio (step S43). Specifically, as described above, the determination unit 104 determines the growth status of the fruit 10 by estimating the sugar content of the fruit 10 based on the calculated ratio.

  Thus, the information processing apparatus 100 ends the growth status determination process.

(effect)
As described above, according to the information processing apparatus 100 according to the present embodiment, the growth status of fruits and vegetables can be managed with high accuracy in a non-contact manner without damaging the fruits.

  This is because, based on the information indicating the diameter and height of the fruit 10 extracted from the photographed image by the extraction unit 102, the calculation unit 103 calculates the ratio between the diameter and the height, and the determination unit 104 determines the calculated ratio. This is because the growth status of the fruit 10 is determined on the basis thereof.

  As described above, the growth status of the fruit 10, particularly the sugar content, has a correlation with the ratio between the diameter and the height of the fruit 10. Since the information processing apparatus 100 according to the present embodiment determines the growth status based on the ratio between the diameter and the height of the fruit 10 that has a correlation with the sugar content, the growth status of the fruit 10, particularly the sugar content, is determined. it can. Moreover, since the information which shows this diameter and height is extracted from a picked-up image, an operator does not touch the fruit 10. Thereby, the information processing apparatus 100 can extract information on the diameter and height of the fruit 10 without damaging the fruit.

  Thereby, for example, when the sugar content is low, the growth management system 1 can manage the growth status such as further promoting the growth without harvesting and waiting for the sugar content to increase. Thus, according to the growth management system 1 according to the present embodiment, it is possible to manage the growth of crops, particularly the harvest time of fruit vegetables.

  Note that, in the present embodiment, as shown in FIG. 3, shooting of one fruit vegetable with the input device 110 has been described. When a plurality of fruits 10 are grown on the single fruit vegetable, according to the present embodiment, the sugar content of each of the one or more fruits 10 grown on the single fruit vegetable is calculated. Thereby, the information processing apparatus 100 can manage the growth status of the fruit 10 based on the position where the fruit 10 is produced.

  In addition, when photographing a plurality of fruit vegetables with the input device 110, the information processing apparatus 100 manages the growth status of the fruit 10 for each plant body where the fruit 10 grows in addition to the position where the fruit 10 grows. Can do.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

  A growth management system 2 according to the present embodiment is shown in FIG. FIG. 5 is a diagram showing an example of the configuration of the growth management system 2 according to the present embodiment. As shown in FIG. 5, the growth management system 2 according to the present embodiment includes an information processing device 200, an input device 110, a display device 120, and a storage device 130. The devices are connected to each other using, for example, a LAN cable. In addition, this invention is not limited to this, Each apparatus may be the structure connected to a wireless LAN mutually. In the present embodiment, the input device 110 is assumed to be a camera, and the input data is assumed to be image data indicating a captured image taken by the camera. Note that the time interval at which the input device 110 captures a captured image is not particularly limited.

  In the present embodiment, the camera may photograph the fruit 10 to be photographed at the same time as the bunches and stems on which the fruit 10 grows. The camera is movable or fixedly installed. When the camera is movably installed, the movement of the camera may be controlled by the information processing apparatus 200 or the camera itself.

  In the following description, it is assumed that the information processing apparatus 200 controls the movement of the camera. The information processing apparatus 200 may move the camera so that the fruit to be observed can be photographed from a specific fixed point position. When information indicating the position of the fruit 10 is stored in the storage device 130, the information processing apparatus 200 acquires this information from the storage device 130 and places the camera at a position where the fruit 10 at the position can be photographed. It may be moved. Further, the camera may have a function of continuously photographing the plurality of fruits 10 while moving. In addition, the camera may photograph a plurality of fruits 10 in the canopy under an appropriate lens magnification and camera pixel resolution.

(Information processing apparatus 200)
Next, the configuration of the information processing apparatus 200 of the growth management system 2 according to the present embodiment will be described with reference to FIG. FIG. 6 is a functional block diagram illustrating an example of a functional configuration of the information processing apparatus 200 of the growth management system 2 according to the present embodiment. As illustrated in FIG. 6, the information processing apparatus 200 according to the present embodiment includes an extraction unit 102, a calculation unit 103, and a determination unit 204. That is, the information processing apparatus 200 includes a determination unit 204 instead of the determination unit 104 of the information processing apparatus 100 described above.

  Similar to the extraction unit 102 in the first embodiment described above, the extraction unit 102 extracts the region of the fruit 10 from the image data. At this time, the extraction unit 102 may extract the region of the fruit 10 by specifying the regions of the tufts and stems from the image data. Thereby, even if it is image data which shows the image in which the fruit 10 is contained in multiple numbers, the area | region of the fruit 10 can be extracted for every fruit 10. FIG.

  Similar to the determination unit 104 in the first embodiment described above, the determination unit 204 determines the growth status of the fruit 10 based on the ratio between the diameter and the height of the fruit 10 calculated by the calculation unit 103.

  Further, the determination unit 204 determines whether or not the fruit 10 can be harvested based on the ratio of the diameter to the height of the fruit 10. Specifically, the determination unit 204 determines whether or not harvesting is possible with reference to the harvesting determination data stored in the storage device 130 connected to the information processing apparatus 100.

  For example, it is assumed that the above-described formula (1) obtained from the graph shown in FIG. 3 or the graph shown in FIG. If the sugar content that increases the commercial value of the fruit and the sugar content that humans feel delicious is 5%, the ratio of the diameter to the height (diameter / height) that exceeds this sugar content is shown in the graph of FIG. About 1.2 or more. For this reason, in the present embodiment, the diameter / height value of 1.2 is set as a threshold value used for determining whether or not harvesting is possible. This threshold value is an example and is not limited to this value. The threshold used for determining whether or not to harvest is set for each canopy position, for each house, and for each area in the house while looking at the data on the distribution of sugar content and diameter / height at the sampled and measured fruit positions. It may be.

  Therefore, it is assumed that the threshold (1.2 in the present embodiment) used for determining whether harvesting is possible is stored in storage device 130 as data for determining whether harvesting is possible. Note that the data for determining whether or not harvesting is possible may be stored in the determination unit 204.

  And the determination part 204 determines whether the ratio of the diameter with respect to the height of the fruit 10 is more than the threshold value used for determination of the possibility of harvesting. And when the ratio of the diameter with respect to the height of the fruit 10 is more than the said threshold value, the determination part 204 determines with this fruit 10 being harvestable.

  Note that the determination unit 204 may determine whether or not the fruit 10 can be harvested based on the determination result of the growth state. The determination result of the determination unit 204 may be, for example, sugar content or other determination results. At this time, the threshold value used for determining whether or not harvesting is possible is not limited to the ratio of the diameter to the height of the fruit 10, and may be any value that can be compared with the determination result, for example, sugar content.

  For example, it is assumed that the determination result of the growth state is the sugar content of the fruit 10, and the threshold used for determining whether or not harvesting is possible is a value indicating the sugar content (for example, 5%). The determination unit 204 may determine whether or not harvesting is possible by comparing the determination result (sugar content of the fruit 10) with this threshold value.

  Then, like the determination unit 104, the determination unit 204 outputs the determination result of the growth status to the display device 120. Furthermore, the determination unit 204 outputs information indicating whether or not the fruit 10 can be harvested (determination result regarding whether or not the harvest is possible) to the display device 120.

  The display device 120 displays the determination result of the growth status on the screen. When the determination result of the growth status of the fruit 10 is the sugar content of the fruit 10, the display device 120 displays the sugar content of the fruit 10 at the time of photographing. Further, the display device 120 displays on the screen the result of the determination unit 204 determining whether or not harvesting is possible (the result of determining whether or not harvesting is possible). The display device 120 may display the growth status determination result and the harvest availability determination result on the same screen or on different screens. The method by which the display device 120 displays the growth status determination result and the harvest availability determination result on the screen is not particularly limited.

  Thereby, the operator can confirm the fruit 10 determined to be harvestable by the determination unit 204 on the display device 120. Therefore, the worker can harvest the fruit 10 having a sugar content that a person feels delicious.

  Note that the determination unit 204 may store the determination result of the growth status and the determination result of whether harvesting is possible in the storage device 130.

(Operation of the information processing apparatus 200)
Next, with reference to FIG. 7, the harvest availability determination process in the information processing apparatus 200 of the growth management system 2 according to the present embodiment will be described. FIG. 7 is a flowchart illustrating an example of the flow of the harvest possibility determination process in the information processing apparatus 200 of the growth management system 2 according to the present embodiment.

  As shown in FIG. 7, first, the extraction unit 102 of the information processing device 200 extracts information indicating the diameter and height of the fruit 10 from the image data sent from the input device 110 (step S71).

  Next, the calculation unit 103 calculates the ratio between the diameter and the height of the fruit 10 (step S72).

  Subsequently, based on the ratio calculated by the calculation unit 103 in step S72, the determination unit 204 determines the growth status of the fruit 10 that is the target of calculation of the ratio (step S73).

Moreover, in this Embodiment, although the input device 110 shall image | photograph one plant body as shown in FIG. 8, you may image | photograph a some plant body.

  The measuring device 140 measures information related to the cultivation environment of the plant body from which the fruit 10 grows. The measuring device 140 is, for example, a thermometer that measures the cultivation environment of the fruit 10, a solarimeter that measures the amount of solar radiation with respect to the cultivation environment of the fruit 10, but the present invention is not limited to this. The measuring device 140 may be, for example, a hygrometer that measures the humidity of the cultivation environment, or may be another measuring device. The measuring device 140 stores the measured measurement data in the storage device 330 in association with information indicating the measurement date and time. Note that the measurement apparatus 140 may transmit the measured measurement data to the information processing apparatus 300 in association with information indicating the measurement date and time.

  The storage device 330 stores the same data as the storage device 130 described above. Further, the storage device 330 stores measurement data. Further, the information processing apparatus 300 stores a graph indicating a ratio of the diameter to the fruit height with respect to the integrated temperature and a graph indicating a ratio of the diameter to the fruit height with respect to the integrated solar radiation amount. This will be described with reference to FIG. 9 and FIG.

  FIG. 9 is a graph showing an example of the ratio of the diameter to the fruit height with respect to the accumulated temperature, which is stored in the storage device 330 of the growth management system 3 according to the present embodiment. Moreover, FIG. 10 is a graph which shows an example of ratio of the diameter with respect to the height of the fruit with respect to the amount of integrated solar radiation stored in the memory | storage device 330 of the growth management system 3 which concerns on this Embodiment.

  As shown in FIGS. 9 and 10, it can be seen that the value of the ratio of the diameter to the fruit height increases as the integrated temperature or integrated solar radiation increases. The storage device 330 stores in advance data indicating the relationship between the information relating to the cultivation environment of the plant body and the ratio of the diameter to the fruit height.

(Information processing apparatus 300)
Next, the configuration of the information processing apparatus 300 of the growth management system 3 according to the present embodiment will be described with reference to FIG. FIG. 11 is a functional block diagram illustrating an example of a functional configuration of the information processing apparatus 300 of the growth management system 3 according to the present embodiment. As illustrated in FIG. 11, the information processing apparatus 300 according to the present embodiment includes an extraction unit 102, a calculation unit 103, a determination unit 304, an integrated amount calculation unit 305, and a management unit 306. That is, the information processing apparatus 300 has a configuration in which the determination unit 104 of the information processing apparatus 100 described above is replaced with a determination unit 304 and further includes an integrated amount calculation unit 305 and a management unit 306. The present embodiment is not limited to this, and the information processing apparatus 300 replaces the determination unit 204 of the information processing apparatus 200 described above with the determination unit 304, and further includes an integrated amount calculation unit 305 and a management unit 306. May be provided.

  The integrated amount calculation unit 305 acquires the measurement data stored by the measurement device 140 from the storage device 330. In a configuration in which measurement data is transmitted from the measurement device 140, the integrated amount calculation unit 305 receives the measurement data transmitted from the measurement device 140. The integrated amount calculation unit 305 is measurement data indicating the temperature and the amount of solar radiation measured by the measuring device 140, and is measured within a predetermined period from the date and time when the image data was captured (imaging time) or the imaging time. Based on the measurement data, the integrated amount of temperature and solar radiation is calculated. Here, the past integrated amount used when the integrated amount calculating unit 305 calculates the integrated amount of the temperature and the solar radiation amount may be stored in the integrated amount calculating unit 305 or stored in the storage device 330. It may be. In addition, when the measuring device 140 has a function of calculating the integrated amount, the storage device 330 may store the integrated amount. In this case, the integrated amount calculation unit 305 may acquire the integrated amount from the storage device 330.

  Then, the integrated amount calculation unit 305 outputs the calculated or acquired integrated amount to the determination unit 304.

  Similar to the determination unit 104 according to the first embodiment described above, the determination unit 304 determines the growth status of the fruit 10 based on the ratio of the diameter and height of the fruit 10 calculated by the calculation unit 103. . Note that the determination unit 304 may determine whether or not harvesting is possible, similar to the determination unit 204 according to the second embodiment described above.

  Further, the determination unit 304 receives an integrated amount of temperature (integrated temperature) and an integrated amount of sunshine amount (integrated sunshine amount) from the integrated amount calculation unit 305. And the determination part 304 determines the condition (cultivation condition) where the fruit 10 is cultivated based on this integration amount and the said ratio.

  Specifically, the determination unit 304 uses the accumulated temperature and data (for example, the graph shown in FIG. 9) indicating the relationship between the accumulated temperature and the ratio of the diameter to the fruit height stored in the storage device 330. It is used to determine the cultivation status of the fruit 10 to be determined. For example, the determination unit 304 uses the graph shown in FIG. 9 to calculate the ratio of the diameter to the fruit height (referred to as the first ratio) at the calculated or acquired integrated temperature. Then, the determination unit 304 compares the calculated first ratio with the ratio of the diameter to the fruit height calculated by the calculation unit 103.

  When the ratio calculated by the calculation unit 103 is smaller than the first ratio, the determination unit 304 determines that the ambient temperature of the fruit 10 is lower than the temperature of the cultivation environment of the plant body including the fruit 10. When the ratio calculated by the calculation unit 103 is greater than the first ratio, the determination unit 304 determines that the ambient temperature of the fruit 10 is higher than the temperature of the cultivation environment of the plant body including the fruit 10. When the ratio calculated by the calculation unit 103 is the same as the first ratio, the determination unit 304 determines that the ambient temperature of the fruit 10 is the same temperature as the cultivation environment of the plant body including the fruit 10.

  In addition, when the ratio calculated by the calculation unit 103 is within a predetermined range from the first ratio, the determination unit 304 is such that the ambient temperature of the fruit 10 is the same temperature as the cultivation environment of the plant body including the fruit 10. You may judge. At this time, when the ratio calculated by the calculation unit 103 exceeds the upper limit value within a predetermined range from the first ratio, the determination unit 304 determines that the ambient temperature of the fruit 10 is higher than the temperature of the cultivation environment of the plant body including the fruit 10. You may determine with high. Similarly, when the ratio calculated by the calculation unit 103 is lower than the lower limit value of the predetermined range from the first ratio, the determination unit 304 determines that the ambient temperature of the fruit 10 is higher than the temperature of the cultivation environment of the plant body including the fruit 10. You may determine with low.

  Further, the determination unit 304 uses the accumulated amount of sunlight and data (for example, the graph shown in FIG. 10) that is stored in the storage device 330 and indicates the relationship between the accumulated amount of sunlight and the ratio of the diameter to the fruit height. Then, information (cultivation status) of the environment where the fruit 10 to be determined is cultivated is determined. For example, the determination unit 304 uses the graph shown in FIG. 10 to calculate the ratio of the diameter to the fruit height (second ratio) in the calculated or received integrated amount of sunshine. Then, the determination unit 304 compares the calculated second ratio with the ratio of the diameter to the fruit height calculated by the calculation unit 103.

  When the ratio calculated by the calculation unit 103 is smaller than the second ratio, the determination unit 304 determines that the solar radiation amount around the fruit 10 is lower than the solar radiation amount in the cultivation environment of the plant body including the fruit 10. When the ratio calculated by the calculation unit 103 is larger than the second ratio, the determination unit 304 determines that the amount of solar radiation around the fruit 10 is higher than the amount of solar radiation in the cultivation environment of the plant body including the fruit 10. When the ratio calculated by the calculation unit 103 is the same as the second ratio, the determination unit 304 determines that the solar radiation amount around the fruit 10 is the same as the solar radiation amount in the cultivation environment of the plant body including the fruit 10.

  When the ratio calculated by the calculation unit 103 is within a predetermined range from the second ratio, the determination unit 304 is configured so that the amount of solar radiation around the fruit 10 is the amount of solar radiation in the cultivation environment of the plant body including the fruit 10. You may determine with it being the same. At this time, when the ratio calculated by the calculation unit 103 exceeds the upper limit value of the predetermined range from the second ratio, the determination unit 304 has a plant environment including the fruit 10 where the amount of solar radiation around the fruit 10 is. It may be determined that the amount of solar radiation is higher. Similarly, when the ratio calculated by the calculation unit 103 is lower than the lower limit value of the predetermined range from the second ratio, the determination unit 304 has an amount of solar radiation around the fruit 10 in the cultivation environment of the plant body including the fruit 10. It may be determined that the amount of solar radiation is lower.

  Moreover, the determination part 304 may determine the determination of the cultivation status of the fruit 10 based on the determination result of the growth status of the fruit 10.

  Then, the determination unit 304 outputs information on the cultivation status (cultivation status determination result) to the management unit 306.

  The management unit 306 receives the cultivation result determination result from the determination unit 304. The management unit 306 manages the growth of the fruit 10 based on the determination result of the cultivation status. Specifically, when the management unit 306 indicates that the ambient temperature of the fruit 10 is higher or lower than the temperature of the cultivation environment of the plant body including the fruit 10, the management unit 306 decreases or increases the ambient temperature of the fruit 10, Seek management methods for plants. For example, the management unit 306 controls a device (not shown) that manages the ambient temperature of the fruit 10 so as to lower or increase the ambient temperature of the fruit 10. Further, for example, the management unit 306 performs processing such as shielding or supplementing the fruit 10 or notifying the worker that it is recommended to lower or increase the ambient temperature of the fruit 10.

  Moreover, the management part 306 manages so that the present condition may be maintained, when the determination result of a cultivation condition shows that the ambient temperature of the fruit 10 and the temperature of the cultivation environment of the plant body containing the fruit 10 are substantially the same. .

  Moreover, the management part 306 supplements with respect to this fruit 10, when the judgment result of a cultivation condition shows that the amount of sunlight around the fruit 10 is lower than the amount of sunlight of the cultivation environment of the plant body containing the fruit 10. Alternatively, a management method such as leaf removal around the fruit 10 is sought. For example, the management unit 306 performs processing such as notifying the worker that supplementing light to the fruit 10 or recommending defoliation around the fruit 10 is recommended.

  When the determination result of the cultivation state indicates that the amount of sunshine around the fruit 10 is higher than the amount of sunshine in the cultivation environment of the plant body including the fruit 10, the management unit 306 shields against the fruit 10, or The management method of refraining the defoliation around the fruit 10 etc. is calculated | required. For example, the management unit 306 performs processing such as notifying the worker that the fruit 10 is recommended to be shielded from light or to refrain from defoliation around the fruit 10.

  Moreover, the management part 306 maintains the present condition, when the determination result of a cultivation condition shows that the solar radiation amount of the periphery of the fruit 10 and the solar radiation amount of the cultivation environment of the plant body containing the fruit 10 are substantially the same. To manage.

  Moreover, when the determination result with respect to temperature and the determination result with respect to the amount of solar radiation conflict, for example, the surrounding temperature of the fruit 10 is lower than the temperature with respect to the cultivation environment of a plant body, and the amount of solar radiation around the fruit 10 is plant. The case where it is higher than the amount of solar radiation with respect to the cultivation environment of a body is demonstrated. In this case, the management unit 306 includes a divergence width (first divergence width) indicating how far the ratio calculated by the calculation unit 103 is different from the first ratio, and the ratio calculated by the calculation unit 103 and the second ratio. A deviation width from the ratio (second deviation width) may be calculated. And the management part 306 may determine the management method of the fruit 10 according to the magnitude with the 1st and 2nd deviation width. For example, when the second divergence width is larger than the first divergence width, the management unit 306 may employ a method for controlling the amount of solar radiation with respect to the fruit 10 as a management method for the fruit 10.

  Moreover, the management part 306 may calculate | require the management method of the fruit 10 by including the calculated 1st and 2nd deviation width in the determination result with respect to a temperature, and the determination result with respect to the amount of solar radiation, respectively.

  Further, the management unit 306 may obtain a management method for the fruit 10 based on the determination result of the growth status of the fruit 10.

  And the management part 306 outputs the management method of the fruit 10 calculated | required according to the determination result of the cultivation condition and the determination result to the display apparatus 120 as information (management information) which shows the management condition of the fruit 10.

  The display device 120 displays the growth status determination result on the screen, similarly to the display device 120 according to the first embodiment. Further, the display device 120 displays the management information of the fruit 10 supplied from the management unit 306 on the screen. The display device 120 may display the growth status determination result and the management information on the same screen or different screens. There is no particular limitation on the method by which the display device 120 displays the growth state determination result and the management information on the screen.

  In addition, the determination part 304 may determine a growth condition and a cultivation condition for every fruit 10, and may determine for every plant body. For example, for each plant body (seedling), the determination unit 304 has a statistical value of the ratio of the diameter to the height of one or more fruits 10 growing on the plant body (for example, an average value, a variance value, a maximum value, Minimum). And the determination part 304 may determine the growth condition and cultivation condition with respect to this plant body using this statistical value. The statistical value may be calculated by the calculation unit 103.

  For example, the determination result of the growth state for the plant body is worse (slower) than the growth state where the growth state of the fruit 10 in the plant body is estimated, or better than the growth state where the growth state of the fruit 10 in the plant body is estimated. It is assumed that the information indicates (early). Based on this determination result, the management unit 306 obtains a management method for the plant body for each plant body.

  Moreover, the determination part 304 may determine a growth condition and a cultivation condition for every bun with respect to one or more fruits 10 grown in one bun. For example, the determination unit 304 calculates a statistical value (for example, an average value, a variance value, a maximum value, a minimum value, etc.) of the ratio of the diameter to the height of one or more fruits 10 grown in the bunches. And the determination part 304 may determine the growth condition and cultivation condition with respect to this bunch using this statistical value. The statistical value may be calculated by the calculation unit 103.

  For example, the determination result of the growth status for the bunches is worse (slower) than the growth status where the growth status of the fruit 10 in the bunches is estimated, or better (early) than the growth status where the growth status of the plant body is estimated. It is assumed that the information is shown. Based on the determination result, the management unit 306 obtains a method for managing the tuft for each tuft. In addition, in the state of the flower before the fruit 10 is fruited, one tuft is a tuft that becomes one tuft.

  Moreover, the determination part 304 may determine a growth condition for every fruit 10, every bunch, and every plant body. And the management part 306 may calculate the management method of the fruit 10, a bunch, and a plant body based on these growth conditions.

  Next, the calculation unit 103 calculates the ratio between the diameter and the height of the fruit 10 (step S122).

  Subsequently, based on the ratio calculated by the calculation unit 103 in step S122, the determination unit 304 determines the growth status of the fruit 10 that is the calculation target of the ratio (step S123). In addition, these step S121-step S123 are the processes similar to the growth condition determination process demonstrated using FIG.

  Thereafter, the integrated amount calculation unit 305 calculates the integrated amount of temperature and solar radiation amount from the measurement data of the plant cultivation environment (step S124). The integrated amount may be calculated by the measuring device 140. Further, step S124 may be performed before or simultaneously with any one of steps S121 to S123.

  Then, the determination unit 304 determines the cultivation status of the fruit 10 to be determined based on the integrated amount calculated by the integrated amount calculation unit 305 in step S124 and the ratio calculated by the calculation unit 103 in step S122.

  A growth management system 4 according to the present embodiment is shown in FIG. FIG. 13 is a diagram illustrating an example of the configuration of the growth management system 4 according to the present embodiment. As shown in FIG. 13, the growth management system 4 according to the present embodiment includes an information processing device 400, an input device 110, a display device 120, a storage device 430, and a measuring device 140. The devices are connected to each other using, for example, a LAN cable. In addition, this invention is not limited to this, Each apparatus may be the structure connected to a wireless LAN mutually. In the present embodiment, the input device 110 is assumed to be a camera, and the input data is assumed to be image data indicating a captured image taken by the camera.

The elapsed time from the predicted start time is calculated. Then, the predicting unit 408 predicts the harvest time of the fruit 10 based on the calculated elapsed time.

  Then, the prediction unit 408 outputs prediction information indicating the predicted harvest time to the display device 120.

  The display device 120 displays the growth status determination result on the screen, similarly to the display device 120 according to the first embodiment. Further, the display device 120 displays the prediction information output from the prediction unit 408 on the screen. The display device 120 may display the growth status determination result and the prediction information on the same screen or on different screens. There is no particular limitation on the method by which the display device 120 displays the growth state determination result and the prediction information on the screen.

  Next, the calculation unit 103 calculates the ratio between the diameter and the height of the fruit 10 (step S152).

  Subsequently, based on the ratio calculated by the calculation unit 103 in step S152, the determination unit 104 determines the growth status of the fruit 10 that is the target of calculation of the ratio (step S153).

The connection point between the bunches and stems is a predetermined reference point, which may be a connection point between the bunches where the fruit 10 grows and the stems, or between the bunches and stems where the other fruits 10 grow. It may be a connection point. When the reference point is set on the plant body, the camera photographs the reference point simultaneously with the fruit 10 as described above. The method for setting the reference point is not particularly limited, and a specific location in the building may be set as the reference point, or a singular point on the shape of the plant may be set as the reference point.

  The storage device 530 stores data similar to that of the storage device 130 described above. Note that the storage device 530 may store data similar to the storage device 330 or the storage device 430 described above. Further, the storage device 530 stores information indicating the set reference point as reference point information. In addition, when the reference point is a point whose position does not change, for example, a specific place in a building, the reference point information may include information indicating the position of the reference point.

(Information processing apparatus 500)
Next, the configuration of the information processing apparatus 500 of the growth management system 5 according to the present embodiment will be described with reference to FIG. FIG. 17 is a functional block diagram showing an example of a functional configuration of the information processing apparatus 500 of the growth management system 5 according to the present embodiment. As illustrated in FIG. 17, the information processing apparatus 500 according to the present embodiment includes an extraction unit 502, a calculation unit 103, a determination unit 104, a pruning target determination unit 501, and a rank assignment unit 509. That is, the information processing apparatus 500 includes an extraction unit 502 instead of the extraction unit 102 of the information processing apparatus 100 described above, and further includes a pruning target determination unit 501 and a rank assignment unit 509. Note that the present embodiment is not limited to this, and the information processing apparatus 500 extracts the information processing apparatus 200, the information processing apparatus 300, and the information processing apparatus 400 described above instead of the extraction unit 102. It may be configured to include a section 502 and further include a pruning target determination section 501 and a rank assignment section 509.

  The extraction unit 502 receives image data transmitted from the input device 110. The extraction unit 502 extracts the area of each fruit 10 from the image (captured image) indicated by the received image data. Further, the extraction unit 502 extracts information indicating the position of each fruit 10. Similar to the extraction unit 102, the extraction unit 502 obtains information indicating the diameter and height of the fruit 10 from the extracted region.

  Here, information indicating the position of each fruit 10 extracted by the extraction unit 502 is obtained from the position of the input device 110 that captured the captured image, the position of each fruit 10 on the image, and the like. Since the extraction method of the information which shows the position of each fruit 10 is not specifically limited, description is abbreviate | omitted in this Embodiment. When the reference point is included in the captured image, the extraction unit 502 specifies the position of the reference point based on the reference point information stored in the storage device 530. And the extraction part 502 calculates | requires the distance from the reference | standard point of each fruit 10 using this specified position and the information which shows the position of each fruit 10. FIG. The extraction unit 502 stores this distance in the storage device 530 for each fruit 10 as position information of the fruit 10. Note that the position information of the fruit 10 is not limited to the distance from the reference point, and may be coordinates on the image, for example.

  The extraction unit 502 supplies information indicating the obtained diameter and height to the calculation unit 103 together with information for identifying each fruit 10. In addition, the extraction unit 502 supplies the position information of the fruit 10 to the rank assigning unit 509 together with information for identifying the fruit 10.

  The rank assigning unit 509 receives the position information of each fruit 10 from the extraction unit 502. The rank assigning unit 509 groups one or more fruits 10 based on the received position information so that the fruits 10 that grow in the same bunch are in the same group.

  The rank assigning unit 509 receives the determination result of the growth status of each fruit 10 from the determining unit 104. And the rank provision part 509 provides a rank with respect to each fruit 10 in a group based on the determination result of the growth condition of the fruit 10 contained in a group for every group. It is assumed that the rank assigned by the rank assigning unit 509 indicates an excellent growth situation. For example, the rank assigning unit 509 assigns a high rank to the fruit 10 with a better growth degree, and assigns a lower rank to the fruit 10 with a poor growth degree.

  And the rank provision part 509 outputs the information which shows the fruit 10 which provided the rank to the pruning object determination part 501 with the information which shows the group to which the provided rank and belong.

  The pruning target determination unit 501 receives information indicating the fruit 10 to which the rank is assigned by the rank assigning unit 509 together with information indicating the group to which the rank is assigned. And the pruning object determination part 501 determines the fruit 10 used as the pruning object according to the rank provided to each fruit 10 with respect to the one or more fruits 10 which belong to the same group.

  For example, the pruning target determination unit 501 leaves the fruit 10 (fruit 10 having a good growth state) to which a high rank is assigned, and determines the other fruit 10 as a pruning target. For example, in the case of large tomatoes, the pruning object determination unit 501 determines that the remaining fruit 10 is a pruning object, leaving 2 to 3 from those with good growth conditions. Moreover, when the growth state of the fruit of the same group (in the same bunch) is too bad, the pruning target determination unit 501 may determine that the whole bunch is a pruning target.

  Then, the pruning target determination unit 501 outputs the determination result of the pruning target to the display device 120. Specifically, the pruning target determination unit 501 acquires position information associated with the fruit 10 determined to be the pruning target from the storage device 430, and the information indicating the fruit 10 and the fruit 10 are associated with each other. The position information is output to the display device 120.

  The display device 120 displays the same information as the display device 120 in each embodiment described above on the screen. Furthermore, the display device 120 displays information indicating the fruit 10 that the pruning target determination unit 501 determines to be the pruning target on the screen. Thereby, the operator can confirm the fruit 10 determined to be the pruning target by the pruning target determination unit 501 on the display device 120. Therefore, the operator can prune the fruit 10 to be pruned. Thereby, the growth management system which concerns on this Embodiment can perform the growth management which leaves only the fruit 10 whose growth degree is better in the same bunch.

(Operation of the information processing apparatus 500)

  As illustrated in FIG. 18, first, the extraction unit 502 of the information processing device 500 extracts information indicating the diameter and height of the fruit 10 from the image data sent from the input device 110 (step S181). Moreover, the extraction part 502 calculates | requires the positional information on the fruit 10 (step S182). Step S181 and step S182 may be performed simultaneously or in reverse order.

  Next, the calculation unit 103 calculates the ratio between the diameter and the height of the fruit 10 (step S183). Subsequently, based on the ratio calculated by the calculation unit 103 in step S183, the determination unit 104 determines the growth status of the fruit 10 for which the ratio is calculated (step S184). In addition, this step S181, step S183, and step S184 are the same processes as step S41, step S42, and step S43 in the growth condition determination process demonstrated using FIG. 4, respectively.

  Then, the rank assigning unit 509 groups the fruits 10 in units of bunches (step S185). And the rank provision part 509 provides a rank with respect to each fruit 10 in a group based on the determination result of the growth condition of the fruit 10 contained in a group for every group (step S186).

  Then, the pruning target determination unit 501 determines the fruit 10 to be pruned according to the rank assigned by the rank assigning unit 509 in step S186 (step S187).

  Thus, the information processing apparatus 500 ends the pruning target determination process.

However, it is possible to construct a form in which various modifications are made by correcting or substituting the above-described embodiments.

  Examples of the present invention will be described below, but the present invention is not limited to such examples.

  In this example, the plant body 9 was cultivated using a system to which the growth management system 1 according to the first embodiment was applied. Here, an outline of the configuration of the growth management system and the cultivation system 90 and the plant body in the present embodiment will be described with reference to FIG. FIG. 20 is a diagram showing an outline of the configuration of the growth management system and the cultivation system 90 in the present embodiment. As shown in FIG. 20, the growth management system used in this embodiment includes an information processing device 11, a camera 12, a display device 13, and a storage device 14.

  The information processing apparatus 11 corresponds to the information processing apparatus 100 according to the first embodiment. The camera 12 corresponds to the input device 110 according to the first embodiment. The display device 13 corresponds to the display device 120 according to the first embodiment. The storage device 14 corresponds to the storage device 130 according to the first embodiment.

  The information processing device 11, the camera 12, the display device 13, and the storage device 14 are connected using a LAN cable.

  The plant body 9 where the fruit grows was cultivated by a cultivation system 90 which is a facility for hydroponically cultivating the plant body 9. The cultivation system 90 includes a cultivation container 91 for hydroponics and a support member 94. In the cultivation container 91, a culture solution 92 that is liquid fertilizer is stored. The support member 94 supports the plant body 9 fixed to the cultivation container 91 so that a predetermined space is formed between the liquid surface of the culture solution 92 in the cultivation container 91 and the support member 94. It is a member.

  In this example, as a plant body 9 for cultivation, a Momotaro variety of tomatoes was used. Further, as the cultivation container 91, a substantially cylindrical polypropylene container having a diameter of 42 cm, a height of 44 cm, and a capacity of 35 L was used. As the culture solution 92, TF concentrated Tomato A manufactured by Toyohashi Seedling Co., Ltd. was used. The electric conductivity of the culture solution 92 was 2 mS / cm.

  Further, the support member 94 was made of a substantially circular expanded polystyrene having a diameter of 38 cm and a thickness of 2 cm. Then, tomato seedlings on which about 5 to 6 leaves were developed were fixed to the support member 94, floated on the culture solution 92 in the cultivation container 91, and cultivated by the liquid level lowering method. The number of cultivated tomato seedlings is two. The cultivation environment was a glass room with a day temperature of 25 degrees, a night temperature of 20 degrees, and a humidity of 60%. The culture medium was changed once / week. As the camera 12, C920 manufactured by Logitech Co., Ltd. was used.

  After planting tomato seedlings, they were cultivated for 7 weeks. During this time, cultivation was carried out while appropriately performing leaf cutting, fruit cutting and flowering so that six fruits were formed per seedling.

  Thereafter, one of the tomatoes grown to a diameter of about 5 cm after fruit set was selected from the fruits formed on the seedlings and photographed using the camera 12. The camera 12 photographed the tomato so that one tomato was captured in one image.

  The information processing apparatus 11 extracted the diameter and height of the tomato from the photographed photographed image. The tomato diameter was 5.2 cm and the tomato height was 4.3 cm. Therefore, the ratio of the diameter to the height calculated by the calculation unit 103 was approximately 1.21. Thereby, the information processing apparatus 11 determined the sugar content of this tomato to be 5.6%. As described above, the information processing apparatus 11 determines that tomatoes having a sugar content that humans feel delicious are cultivated.

  In order to confirm the sugar content of the tomato thus determined, the sugar content of the tomato was measured using a sugar content meter. As the sugar content meter, a pocket sugar content meter PAL-J manufactured by Atago Co., Ltd. was used. As a result of measuring the sugar content of the tomato determined by the information processing apparatus 11 with this sugar content meter, the sugar content was 5.5%.

  Thereby, the information processing apparatus 11 was able to estimate the sugar content having the same value as the sugar content measured by the sugar content meter.

  As a comparative example, as a result of estimating the maturity from the weeping state of the branch where the tomato is growing and the color change of the tomato, the sugar content of the tomato determined to be sufficiently matured from the color change Measured with As a result, the sugar content of this tomato was 4.5%. As a result, it was found that the sugar content estimated from the weeping condition of the branches where the tomatoes were grown and the color change of the tomatoes was different from the sugar content measured with a saccharimeter. Therefore, from the change in the color of tomatoes, it was not possible to accurately determine the growth situation regarding tomato harvesting.
