Description

TECHNICAL FIELD The present invention relates to an irrigation management system that includes an imaging unit that images leaves of cultivated plants.

2. Description of the Related Art For example, the system described in Patent Document 1 is already known as an irrigation system that includes an imaging unit that captures images of leaves of cultivated plants. In this irrigation system, the projected area of the leaves of the cultivated plant is calculated based on the captured image acquired by the imaging unit (the “photographing device” in Patent Document 1).

Furthermore, in this irrigation system, the projected area ratio, which is the ratio of the projected area to the maximum projected area, is calculated. Then, when the projected area ratio is below the liquid supply reference value, the cultivated plants are watered ("liquid supply" in Patent Document 1).

The projected area of a leaf is one of the indicators of the degree of leaf tension. Therefore, according to this watering system, watering can be performed according to the degree of leaf tension.

The gardening facility 1 also has a first watering device 51 and a second watering device 52 .

A captured image V captured by the first camera Ca<b>1 at predetermined time intervals is sent to the first coverage calculation unit 41 . The first coverage calculator 41 calculates the coverage Br of the first group GR1 over time based on the captured image V received.

Note that the coverage Br is the ratio of the area occupied by leaves in the measurement area B (see FIG. 3), which is the area in which the leaves appear in the captured image V. As shown in FIG. Also, the coverage Br is a value indicating the degree of leaf tension. That is, the coverage Br corresponds to the "tension index value" according to the present invention.

Calculation of the coverage rate Br will be described in detail. As shown in FIG. 3, the first coverage rate calculation unit 41 determines areas of branches, leaves, and stems in the captured image V based on the color information of the captured image V and the like. This area is determined as a growing area of the cultivated plant Q, that is, a covered area.

It should be noted that the determination of the branches, leaves, and stem regions may be performed based on the RGB data, or may be performed based on the YUV data. However, in the present embodiment, it is desirable to determine the branches, leaves, and stem regions based on YUV data in order to cope with changes in brightness that accompany changes in weather and time of day.

Then, based on the determination of the covered area, the range in which the cultivated plant Q is positioned in the captured image V is set. As shown in FIG. 3, a range surrounded by four sides is set as a region in which the branches and leaves of the cultivated plant Q are shown, and a range surrounded by these four sides is set as a measurement region B, and the area of the measurement region B Bs is calculated. The area Bs can be calculated by counting the number of dots (minimum unit of pixels in the captured image V) in the measurement region B in the captured image V. FIG.

Also, the leaf area B1 can be calculated by counting the number of dots in the covered area. Then, the ratio of the leaf area B1 to the area Bs is calculated as the coverage Br by the following formula.

Coverage Br = leaf area B1/area Bs

It should be noted that the area Bs of the measurement area B is desirably fixed at the area Bs before the leaves begin to wilt, even if the leaves wilt with the passage of time and the area in which the branches and leaves are captured gradually narrows. . That is, the area Bs is fixed as the area Bs calculated based on the first captured image V among the plurality of captured images V acquired over time, and the leaf area B1 increases with the passage of time. is desirable.

As shown in FIG. 4 , the coverage Br calculated over time by the first coverage calculation section 41 is sent to the first reference coverage setting section 42 and the first control section 44 . The first reference coverage setting unit 42 sets the coverage Br of the first group GR1 at the reference time as the reference coverage ST of the first group GR1.

More specifically, in this embodiment, the reference time is the time period immediately after sunrise. Further, as described above, the first camera Ca1 acquires the captured image V at predetermined time intervals. That is, the first camera Ca1 acquires the captured images V at a plurality of times in the time period immediately after sunrise. As a result, the first camera Ca1 acquires a plurality of captured images V in the time period immediately after sunrise.

The first coverage calculator 41 calculates a plurality of coverages Br based on a plurality of captured images V acquired in a time zone immediately after sunrise. Then, the first standard coverage setting unit 42 sets the 90th percentile value of the plurality of coverages Br as the standard coverage ST.

The present invention is not limited to this, and the first reference coverage setting unit 42 may be configured to set a value other than the 90th percentile value of the plurality of coverages Br as the reference coverage ST. good. For example, the first reference coverage setting unit 42 may be configured to set the maximum value of the plurality of coverages Br as the reference coverage ST. Further, the first standard coverage rate setting unit 42 may be configured to set the average value of the plurality of coverage rates Br as the standard coverage rate ST.

As shown in FIG. 4 , the reference coverage ST set by the first reference coverage setting section 42 is sent to the first reference calculation section 43 .

The user can also enter a wilting factor via control panel 54 . The wilting coefficient is a coefficient corresponding to the target degree of wilting of leaves.

The wilting coefficient input to the control panel 54 is sent to the processing section 4 . Then, the first reference calculation unit 43 calculates the watering reference value for the first group GR1 based on the reference coverage ST received from the first reference coverage setting unit 42 and the wilting coefficient input to the control panel 54. Calculate TH. More specifically, the first reference calculator 43 calculates the watering reference value TH by multiplying the reference coverage ST by the wilting coefficient. The calculated irrigation reference value TH is sent to the first control unit 44 .

Based on the coverage Br received from the first coverage calculation unit 41 and the watering reference value TH received from the first reference calculation unit 43, the first control unit 44 sets the coverage Br to the watering reference value TH. Determine whether or not it is lower than Then, when the coverage Br falls below the watering reference value TH, the first control unit 44 outputs a watering instruction signal.

The output watering instruction signal is sent to the first watering device 51 . The first watering device 51 waters each individual plant Q1 belonging to the first group GR1 according to the watering instruction signal received from the first control unit 44 .

That is, the first control unit 44 causes the first watering device 51 to water the first group GR1 when the coverage Br of the first group GR1 falls below the watering reference value TH of the first group GR1.

Also, the captured image V captured by the second camera Ca<b>2 at predetermined time intervals is sent to the second coverage calculator 45 . Then, the second coverage calculation unit 45, the second reference coverage setting unit 46, the second reference calculation unit 47, and the second control unit 48 are the first coverage calculation unit 41 and the first reference coverage described above. It has the same functions as the setting section 42 , the first reference calculation section 43 and the first control section 44 .

That is, the second coverage calculator 45 calculates the coverage Br of the second group GR2 by performing the same processing as the first coverage calculator 41 .

Also, the second reference coverage setting unit 46 sets the reference coverage ST of the second group GR2 by performing the same processing as the first reference coverage setting unit 42 .

Also, the second reference calculator 47 calculates the irrigation reference value TH of the second group GR2 by performing the same processing as that of the first reference calculator 43 .

Further, the second control unit 48 performs the same processing as the first control unit 44, so that when the coverage Br of the second group GR2 is lower than the watering reference value TH of the second group GR2, the second group The second watering device 52 is caused to water the GR2.

Here, as shown in FIG. 4, the first coverage calculation unit 41 and the second coverage calculation unit 45 constitute a coverage calculation unit 40 (corresponding to the "tension index value calculation unit" according to the present invention). ing. The coverage calculator 40 calculates the coverage Br based on the captured image V acquired by the fixed-point camera Ca.

More specifically, the coverage calculator 40 calculates the coverage Br for each group based on the captured image V acquired by the fixed-point camera Ca.

That is, the cultivation system SY includes a coverage calculation unit 40 that calculates the coverage Br, which is a value indicating the degree of leaf coverage, based on the captured image V acquired by the fixed-point camera Ca. More specifically, the cultivation system SY includes a coverage calculation unit 40 that calculates a coverage Br, which is a value indicating the degree of leaf spreading, for each group based on the captured image V acquired by the fixed-point camera Ca. I have.

Moreover, as shown in FIG. 4, the watering device 50 is comprised by the 1st watering device 51 and the 2nd watering device 52. As shown in FIG. The watering device 50 waters the cultivated plants Q. As shown in FIG.

That is, the cultivation system SY includes a watering device 50 for watering the cultivated plants Q. As shown in FIG. Also, the watering by the watering device 50 is performed individually for each group.

Further, as shown in FIG. 4 , the first controller 44 and the second controller 48 constitute an irrigation controller 49 . The watering control unit 49 controls the watering device 50 . That is, the cultivation system SY includes a watering controller 49 that controls the watering device 50 . Then, when the coverage Br falls below a predetermined watering reference value TH, the watering control unit 49 causes the watering device 50 to water the group corresponding to the coverage Br below the watering reference value TH.

With the configuration described above, as shown in FIG. 5, the coverage Br of the first group GR1 and the second group GR2 basically changes as follows. That is, first, leaf wilting progresses with the passage of time. As a result, the coverage Br decreases over time.

When the coverage Br falls below the watering reference value TH and watering is performed, the degree of leaf tension recovers. This increases the coverage Br.

Thereafter, the progress of wilting of the leaves with the passage of time and the restoration of the degree of tension of the leaves by watering are repeated. Thereby, the coverage Br alternately repeats decrease and increase.

In the example shown in the upper part of FIG. 5, the timing at which the first control unit 44 outputs the watering instruction signal is indicated by an upward arrow. In this example, at each of time t1, time t2, time t4, and time t6, the coverage Br fell below the watering reference value TH, so the first control unit 44 outputs a watering instruction signal. As a result of watering the first group GR1, the coverage Br exceeds the watering reference value TH.

Also, in the example shown in the lower part of FIG. 5, the timing at which the second control unit 48 outputs the irrigation instruction signal is indicated by an upward arrow. In this example, since the coverage Br fell below the watering reference value TH at each of time t3 and time t5, the second control unit 48 outputs a watering instruction signal. As a result of watering the second group GR2, the coverage Br exceeds the watering reference value TH.

In the example shown in FIG. 5, the user sets the wilting coefficient of the second group GR2 to a smaller value than the wilting coefficient of the first group GR1. Therefore, the watering reference value TH for the second group GR2 is lower than the watering reference value TH for the first group GR1. As a result, the number of times of watering to the second group GR2 is less than the number of times of watering to the first group GR1.
