Description

  The present invention relates to a pest occurrence prediction system for predicting the occurrence of pests, a terminal device, a server device, and a pest occurrence prediction method.

  As pest control in agriculture, “early-stage control” is known, which is temporarily performed only when pest damage exceeds an allowable level of economic damage to crops. Early-stage control reduces the total amount of pesticides (agricultural chemicals) used and reduces the control cost itself compared to “preventive control” that is carried out regularly even if no damage is caused by pests. Has the effect of

  Then, as a method for determining the initial stage of pest generation, for example, a pest is captured by a trap such as a pest-sheet (sheet that is coated with an adhesive to capture pests), and the number of pests captured is a predetermined threshold. There is known a method of determining the time when the time is exceeded or the time predicted from the number as the initial stage.

  However, in the above method, since pest counting and initial stage prediction are performed manually, it is difficult to prevent variations in judgment due to human error (counting error or forgetting counting) and experience differences. That is, with the above method, it is difficult to objectively determine the initial stage.

  On the other hand, in recent years, attempts have been made to facilitate and analyze data on the growth and disease state of crops by utilizing ICT (Information and Communication Technology), and various methods for pest monitoring have been proposed.

  For example, Non-Patent Document 1 describes a system for predicting the occurrence of pests based on an automatic pest counting apparatus that combines a home-made electric shock insecticide and a field server.

  Patent Document 1 describes an image processing apparatus that captures a pest sheet installed in a field with a camera or the like, detects a pest from the captured image, and counts the number thereof.

JP 2012-161269 A (page No. 6, 7, FIGS. 1, 2, 7)

"Prediction system for pest occurrence using field server and electric shock insecticide"

  The field server in Non-Patent Document 1 is a small observation system equipped with a camera, multiple sensors (sensors that measure temperature, humidity, amount of solar radiation, etc.), lighting, solar cells, etc., for measuring the outdoor environment in remote areas such as farms. It is a robot and expensive. Therefore, if such an expensive device is installed in many places for multipoint observation, the system cost increases.

  Further, as in Patent Document 1, in a technique for recognizing a pest from a photographed image, a measurement error (such as a pest cannot be recognized due to the color or shape of the pest, or a completely unrelated object is erroneously recognized as a pest). It is difficult to eliminate completely.

  If the number of pests is counted less than the actual number due to the above measurement error, the control period may be delayed and the pest damage may be increased. On the other hand, when the number of pests is counted more than the actual number, pest control that is not necessary is executed, which may increase the total amount of pesticide (agrochemical) used and the control cost.

  ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure, it becomes possible to perform pest generation | occurrence | production prediction with higher precision.

It is a block diagram which shows the structural example of the pest occurrence prediction system which concerns on embodiment of this invention. It is a figure which shows the structural example of a insect repellent sheet information. It is a figure which shows the structural example of total calculation basic information. It is a figure for demonstrating the pest generation | occurrence | production prediction example in a prediction part. FIG. 5 is a flowchart for explaining an operation example of the terminal device shown in FIG. FIG. 6 is a flowchart for explaining an operation example of the server apparatus shown in FIG.

  FIG. 1 is a block diagram illustrating a configuration example of a pest occurrence prediction system 10 according to an embodiment of the present invention.

  The pest occurrence prediction system 10 includes a terminal device 20 and a server device 30. The terminal device 20 is connected to the server device 30 via the network 40.

  The terminal device 20 includes a camera 22, a position information acquisition unit 24, and a control unit 26. The terminal device 20 is typically a mobile phone or a smartphone, for example.

  The camera 22 captures image data A by photographing the prosthetic sheet 50 set in advance at various locations in the field. Image data A is output to the control unit 26.

  The position information acquisition unit 24 acquires position information B of the prosthetic sheet 50. The position information B is output to the control unit 26. In the present embodiment, the position information acquisition unit 24 acquires position information from a satellite positioning system such as GPS (Global Positioning System). Strictly speaking, the position information is the position of the terminal device 20, not the position of the prosthetic sheet 50 itself. However, in reality, since the photographing of the insect repellent sheet 50 by the camera 22 is performed close to the insect repellent sheet 50, the position of the terminal device 20 is substantially equal to the position of the insect repellent sheet 50. Can be considered.

  The control unit 26 creates the prosthetic sheet information C (see FIG. 2) including the image data A and the position information B. Insect sheet information C is transmitted to the server device 30 via the network 40.

  The server device 30 includes an image analysis unit 32 and a prediction unit 34. The server device 30 is typically a cloud server.

  The image analysis unit 32 receives the prosthetic sheet information C from the terminal device 20. The image analysis unit 32 analyzes the image data A included in the insect repellent sheet information C for each of the insect repellent sheets 50, counts the number of pests D for each of the insect repellent sheets 50, and calculates the number of pests D and the position information B. Including total basic information E (see FIG. 3).

  The prediction unit 34 inputs the aggregate basic information E for each of the plurality of prosthetic sheets 50. The prediction unit 34 predicts the occurrence of pests based on the aggregate basic information E for each of the plurality of supplementary insect data 50.

  For example, the prediction unit 34 classifies the plurality of prosthetic sheets 50 into one of a plurality of small areas divided in the pest prediction range based on the position information B included in the aggregate basic information E. The prediction unit 34 determines the number of representative pests for each of the plurality of small regions based on a predetermined determination rule. For example, the prediction unit 34 calculates the average value of the number of pests for each small area, and sets the average value as the number of representative pests for each small area. The prediction unit 34 predicts the occurrence of pests based on at least a plurality of representative pest numbers. The prediction unit 34 transmits the prediction result F to the terminal device 20 via the network 40.

  FIG. 4 is a diagram for explaining an example of pest occurrence prediction in the prediction unit 34. FIG. 4 shows a pest prediction range divided into 3 × 3 small areas. The number in each small area indicates the representative pest number (for example, the average value of the number of pests in each small area). The prediction unit 34 predicts the pest flight direction, the pest arrival time to each field, and the like based on the spatial distribution of the representative pest numbers in the pest prediction range. FIG. 4 is a simplified description for more clearly explaining the method for predicting the occurrence of pests. Therefore, it is needless to say that the description of FIG. 4 and the actual operation differ in the number of divided small areas and the number of representative pests.

  FIG. 5 is a flowchart for explaining an operation example of the terminal device 20 shown in FIG.

  The camera 22 captures the prosthetic sheet 50 set in advance at various locations in the field and acquires image data A (step S1). Image data A is output to the control unit 26.

  The position information acquisition unit 24 acquires the position information B of the prosthetic sheet 50 (step S2). The position information B is output to the control unit 26.

  The control unit 26 creates the prosthetic sheet information C (see FIG. 2) including the image data A and the position information B (step S3). The control unit 26 transmits the insect repellent sheet information C to the server device 30 via the network 40 (step S4).

  Note that the order of the processing in step S1 and the processing in step S2 in FIG. 4 may be reversed or simultaneous.

  FIG. 6 is a flowchart for explaining an operation example of the server apparatus 30 shown in FIG.

  The image analysis unit 32 receives the prosthetic sheet information C from the terminal device 20 (step S10).

  The image analysis unit 32 analyzes the image data A included in the insect repellent sheet information C for each of the insect repellent sheets 50, counts the number of pests D for each of the insect repellent sheets 50, and calculates the number of pests D and the position information B. The total counting basic information E (see FIG. 3) is output (step S11).

  The prediction unit 34 inputs the aggregate basic information E for each of the plurality of prosthetic sheets 50. The predicting unit 34 predicts the occurrence of pests based on the aggregate basic information E for each of the plurality of supplementary insect data 50 (step S12). The specific prediction method is as described above.

  The prediction unit 34 transmits the prediction result F to the terminal device 20 via the network 40 (step S13).

  As described above, in the present embodiment, not only the image data but also the position information is acquired at the time of photographing the prosthetic sheet 50. Therefore, measures to reduce measurement errors that occur when recognizing pests from captured images (for example, measures to absorb measurement errors by calculating the number of representative pests for each small area as described above. ) Can be taken.

  Moreover, in the pest occurrence prediction system 10 of the present embodiment, the terminal device 20 that is a means for capturing the image of the insect repellent sheet 50 and acquiring the image data is configured by a mobile phone, a smartphone, or the like, which is a very general-purpose device. be able to. Therefore, even when pest occurrence prediction is performed over a wide range, the apparatus cost does not increase as in Non-Patent Document 1.

  Summarizing the above, according to the present embodiment, it is possible to perform pest occurrence prediction with higher accuracy while having a simple device configuration.

  Note that the pest occurrence prediction in the prediction unit 34 is performed in consideration of not only the spatial change as described above but also a temporal change (comparison with past data) and parameters other than the number of pests (for example, weather data). It may be broken.

  In addition, the position information C may be coordinate information of the insect sheet 50 embedded in a one-dimensional or two-dimensional barcode directly printed on or attached to the insect sheet 50. At this time, when the embedded position information is the position information unique to the insect sheet 50 measured in advance, the position of the insect sheet 50 is more accurately compared to the case where the imaging position is regarded as the position of the insect sheet 50. I can grasp it. By more accurately grasping the position of each supplementary sheet 50, the accuracy of classification of the supplementary sheet 50 is also improved. Therefore, the risk of misclassification is reduced, and as a result, measurement errors can be further reduced.

  Note that the bar code may not include the position information of the insect repellent sheet 50 and may be embedded only with an ID (identification) for identifying the insect capturing sheet 50. In this case, the server device 30 side may separately associate the ID and the position information.

  The association between the ID and the position information may be specified by the user based on the map information on the server device 30 side, for example.

  Alternatively, the location information obtained by the terminal device 20 by GPS or the like is transmitted to the server device 30 together with the ID without managing the location in advance, and the location information received by the server device 30 is managed for each ID to obtain the ID and location information. May be automatically performed. By doing in this way, the operation | work which determines an installation place beforehand, when printing a barcode on the insect capturing sheet 50, the operation | work which designates the position on a map by the server apparatus 30 side, etc. can be abbreviate | omitted.

  At this time, the position information transmitted multiple times for the same ID in time series is gradually improved in accuracy (in other words, the position information of each ID is gradually increased by a predetermined statistical process (for example, average)). GPS measurement errors can be suppressed).

  Note that the position information of the prosthetic sheet 50 embedded in a one-dimensional or two-dimensional barcode may be identification information indicating which small region it belongs to, instead of specific coordinate information.

  In addition, the destination information (for example, URL (Uniform Resource Locator)) of the server device 30 that transmits the worm sheet information C is embedded in the one-dimensional or two-dimensional barcode, and the control unit 26 recognizes this and transmits it. It can also be set as the structure to do. By doing so, it is possible to reduce the risk of erroneous transmission of the prosthetic sheet information C.

  In addition, degradation of image quality (camera shake or blur) of the photographed image can be cited as a factor that reduces the insect counting accuracy in the image of the insect capturing sheet 50 photographed by the terminal device 20. In order to prevent the image quality deterioration, the line thickness of the one-dimensional barcode or the dot size of the two-dimensional barcode is made to be substantially the same as the size of the insect to be counted. Then, when a predetermined area to be imaged of the insect capturing sheet 50 including the one-dimensional barcode or the two-dimensional barcode is photographed by the camera 22 of the terminal device 20, if the barcode is successfully read from the photographed image, the photographing is performed. The image is transmitted to the server device 30. If the image is unsuccessful, the captured image is discarded and re-photographing is executed.

  In other words, in the above configuration, whether or not the image quality of the captured image is an image quality that may cause a decrease in counting accuracy is automatically determined based on whether or not the barcode reading is correct. And many terminal devices 20, such as a smart phone, have a barcode recognition function as a standard function, and it does not cost the system. Furthermore, since barcode recognition processing can be performed at high speed, the user is not burdened with waiting time or the like. Therefore, according to the above-described configuration, it is possible to prevent a decrease in insect counting accuracy in the insect repellent sheet 50 without adding a special device and without putting extra effort on the user.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to description of the said embodiment. It is obvious to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. Therefore, it is needless to say that embodiments with such changes or improvements are also included in the technical scope of the present invention.
