Description

Technical Field

[0001] The present invention relates to the technical field of granary insect monitoring technology, and in particular to a large-viewing angle shooting component of a granary insect monitoring device and an insect pest image processing system. Background Art

[0002] In the grain warehouse of the storage industry, in order to ensure the quality of grain, it is necessary to timely understand the pest situation in the grain pile, including the number, type, insect-infested area, and environment where pests breed, so as to carry out targeted pest control in time or take preventive measures in advance. Pests and insect pests can cause huge grain losses. The losses caused by pests each year account for 30% of the total losses, so pest control must be given great attention. The first step in prevention and control is to investigate the insect situation, including whether there are insects, the types and density of pests. The commonly used monitoring method is to first use a special structure trap to use the characteristics of insects that like height, love to drill holes, and like special smells to induce insects to crawl in, and then extract the insects out of the warehouse through the trachea for counting. However, this monitoring method must ensure that the insects will actively enter the trap and cannot escape on their own. It may also not be able to effectively trap some types of insects. Of course, there are also some monitoring equipment that use video methods, but they are also trapped first and then filmed on the spot. At the same time, because some larvae do not walk and live inside a grain, such as the most serious rice weevil, they cannot be trapped, which also means that existing monitoring methods are unable to monitor the insect situation during the larval stage.

[0003] In order to solve the above problems, Patent Publication No. CN112616795A proposes an endoscopic grain insect monitoring system and method. The endoscopic grain insect monitoring system is provided with a plurality of endoscopic camera devices. The inner cylinder side of the endoscopic camera device is provided with a plurality of camera windows. Each camera window corresponds to a camera. Each camera is surrounded by an attracting light for attracting pests. The scheme eliminates the trap and only relies on the attracting light to attract pests. When shooting, the pests are in a free-moving state, and it is inevitable that there will be system misjudgments. The trap can stick to the pests, and the feature capture is more stable. It can be seen that the trap method still has its advantages.

[0004] In addition, although the above scheme increases the shooting range through cameras at different heights, the shooting angle of each camera is a horizontal angle of view perpendicular to the cylinder, and each circular window limits the maximum shooting angle of the camera. There is no correlation between the various shooting images. When shooting freely moving pests, when the same pest moves from circular window 1 to circular window 2, due to the limitation of the shooting angle, the same pest may be photographed by two different cameras through the corresponding windows and repeatedly counted by the system, which affects the monitoring of the actual situation of pests in the granary.

[0005] Therefore, developing an insect monitoring device that is compatible with both traps and attractant lights and has a wide-angle shooting structure has become an urgent problem to be solved in the market. Summary of the invention

[0047] In order to better understand the purpose, technical scheme and technical effect of the present invention, the present invention is further explained in conjunction with the accompanying drawings and embodiments. It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, it is stated that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

[0048] It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may also be a central element, and when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0049] The indicated orientation or position relationship is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the application is usually placed when used, or the orientation or position relationship commonly understood by technical personnel in this field, or the orientation or position relationship in which the product of the application is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0050] The terms "first", "second" and "third" are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Several" means two or more, unless otherwise clearly and specifically defined.

[0051] like Figures 1 to 6 As shown, a wide-angle shooting component 2 of a grain silo insect monitoring device is arranged in a cylinder 1 of the grain silo insect monitoring device, and the wide-angle sealed shooting component 2 includes a U-shaped heat sink 21, a glass cover plate 22, a bottom plate 23 and a circuit board 24. The U-shaped heat sink 21, the glass cover plate 22 and the bottom plate 23 constitute a rectangular chamber with a top opening, and the circuit board 24 is built in the rectangular chamber; a wireless communication component 4 is provided at the top opening of the rectangular chamber to block the top opening; it can be seen that the U-shaped heat sink 21, the glass cover plate 22 and the bottom plate 23 and the wireless communication component 4 constitute a closed rectangular chamber, which helps to protect the internal circuit board 24 and the camera from external environmental factors (such as temperature changes, humidity, etc.), increase the durability and working stability of the equipment, and improve the service life of the product.

[0052] like Figure 4As shown, the bottom area of ​​the circuit board 24 is provided with a first camera 25, and the top area is provided with a second camera 26. The first camera 25 is vertically oriented toward the glass cover plate 22, and the second camera 26 is tilted toward the glass cover plate 22 and tilted toward the side of the first camera 25, so that the pictures taken by the two cameras are partially overlapped and form a continuous large-angle shooting picture; in a specific embodiment, the tilt angle of the second camera 26 is 40° to 50°, and the tilt angle of 40° to 50° enables the second camera to cover a larger vertical space, which complements the horizontal viewing angle of the first camera, ensuring the comprehensive monitoring of pest activities at different heights inside the granary and reducing the monitoring blind area; the design of the tilt angle can provide a better shooting angle, especially when shooting pests close to the glass cover plate, more obvious pest morphological characteristics can be obtained, which is conducive to subsequent data processing and analysis. It can be seen that by setting the first camera 25 and the second camera 26, and making the pictures taken by the two cameras partially overlap to form a continuous large-angle shooting picture, it can ensure full coverage of the pest activity area in the granary. This structure can not only capture adult insects in a freely moving state, but also avoid the problem of repeated counting of the same pest due to limited shooting angles, thereby improving the accuracy and comprehensiveness of pest monitoring.

[0053] A third camera 27 is provided at the lower edge of the circuit board 24. The third camera 27 is vertically oriented toward the bottom plate 23 and photographs the interior of the trap 51 below the cylinder 1 through the light-transmitting hole of the bottom plate 23. It can be seen that the present invention retains the trap 51 trapping shooting mode to obtain more stable pest technical characteristics, which is conducive to improving identification accuracy; at the same time, the luring shooting mode is added; the device combines the trapping shooting and the luring light shooting, which can not only monitor the pests entering the trap 51, but also effectively identify the larvae living inside the grain.

[0054] The shooting data of the first camera 25, the second camera 26 and the third camera 27 are all transmitted to the data processing system through the wireless communication component 4 to identify the type and quantity of pests. The present invention optimizes data transmission and processing, and the shooting data of all cameras are transmitted to the data processing system in real time through the wireless communication component 4, which improves the speed and efficiency of data analysis, and is also conducive to subsequent data management and decision support.

[0055] In this embodiment, the circuit board 24 includes a main board 241, a first sub-board 242 and a second sub-board 243. The first sub-board 242 is plugged obliquely into the top area of ​​the main board 241, and the second sub-board 243 is plugged vertically into the lower edge of the main board 241; the second camera 26 is welded to the first sub-board 242, and the third camera 27 is welded to the second sub-board 243. By installing the cameras on independent sub-boards and plugging them at different angles (oblique and vertical), a more complex shooting layout can be achieved in a limited space without increasing the volume of the overall device. The oblique plugging of the first sub-board 242 allows the second camera 26 to face the glass cover 22 at a specific angle, ensuring partial overlap with the first camera 25 shooting picture, thereby forming a continuous wide-angle shooting picture, so that the movement path of pests can be better captured and a more comprehensive monitoring angle can be provided. In addition, the use of the main board 241 plus the sub-board method makes the entire system have a higher degree of modularity. If a problem occurs in a certain component, only the corresponding sub-board needs to be replaced without replacing the entire circuit board 24, which reduces maintenance costs and improves the maintainability of the system; allocating components with different functions to their respective sub-boards can make wiring clearer and more orderly, and reduce the possibility of signal interference; because the heat-generating elements on each sub-board are more dispersed, compared with the traditional integrated circuit board 24 design, this solution can dissipate heat more effectively, reduce the risk of failure due to overheating, and improve the stability of equipment operation.

[0056] In this embodiment, a first attracting light 251 and a first fill light 252 are provided on the main board 241 adjacent to the first camera 25; a second attracting light 261 is provided on the main board 241 adjacent to the second camera 26, and second fill lights 262 are provided on both sides of the second camera 26 on the first sub-board 242; and third fill lights 271 are provided on both sides of the third camera 27 on the second sub-board 243.

[0057] The attractant light set near the camera can effectively attract pests to the shooting area, increasing the probability of the pests being captured. In particular, for pests that are sensitive to specific light or have phototropism, the monitoring coverage can be significantly improved. The fill light ensures that the camera can obtain clear, high-contrast images even under low-light conditions. Especially at night or when there is insufficient light inside the granary, the fill light can provide sufficient lighting to make the characteristics of the pests more obvious, which is convenient for subsequent data processing and analysis. It can be seen that the present invention not only improves the attractiveness of pests through the combined use of fill lights and attractant lights, but also improves the shooting environment through appropriate lighting conditions, reduces the influence of shadows and reflections, thereby improving the quality of the image and making pest identification more accurate.

[0058] In a preferred embodiment, the first attracting light 251 is located above the first camera 25, the first fill light 252 is located below the first camera 25, and the first attracting light 251, the first camera 25 and the first fill light 252 are arranged obliquely. The light guidance of the inclined attracting light and the camera combination creates a guiding path from top to bottom. Pests tend to be phototropic and move along the direction of the light source. Pests may spend more time looking for the best position of the light source in the monitoring area, which increases their chances of staying in front of the camera, which is conducive to obtaining more image data, thereby improving the accuracy of identifying the type and quantity of pests.

[0059] In this embodiment, the glass cover plate 22 is sealed and connected to the opening between the left and right side walls of the U-shaped heat sink 21 by glass glue, and the outer wall surfaces of the left and right side walls are provided with heat dissipation fins. A transparent plate is provided between the bottom plate 23 and the U-shaped heat sink 21, and the transparent plate is used to seal the bottom of the U-shaped heat sink 21; the bottom plate 23 is provided with three light-transmitting holes, and the three light-transmitting holes correspond to the third camera 27 and the second fill light 262 on both sides thereof. The provision of heat dissipation fins increases the heat dissipation area, improves the heat dissipation efficiency, helps to quickly dissipate the heat generated by the attracting light, fill light and other electronic components, keeps the internal temperature of the device within a suitable working range, prolongs the service life of the electronic components, and ensures the long-term stable operation of the system. The transparent plate not only plays a sealing role, but also allows the third camera 27 to clearly shoot the scene in the trap 51 through the light-transmitting hole of the bottom plate 23, ensures that the light can penetrate smoothly, and avoids the influence of the external environment on the shooting, such as dust or debris blocking the lens, thereby improving the image quality. It can be seen that the wide-angle shooting component 2 adopts a sealed design, which reduces the possibility of dust and other pollutants entering, and reduces the frequency of regular cleaning and maintenance. Even if cleaning is required, the glass cover plate 22 or transparent plate can be removed and reinstalled relatively easily for cleaning without affecting the internal components.

[0060] like Figure 5 and Figure 6As shown, in this embodiment, the two opposite side walls of the cylinder 1 are respectively provided with a rectangular window 11 and a plurality of insect holes 12. The rectangular window 11 is formed by a rectangular notch after a part of the side wall of the cylinder 1 is cut off, and the rectangular notch is close to the glass cover plate 22. An insect entry channel 17 is provided inside the cylinder 1 near the insect hole, and the insect entry channel 17 is connected to the trap 51. The trap 51 is provided with an attractant and a sticky substance. The attractant is used to attract pests, and the sticky substance is used to stick to the pests. Further, an inclined surface is provided on the inner side of the edge of the rectangular window 11 to form a glue filling channel 13 between the rectangular window 11 and the glass cover plate 22. The rectangular window 11 is close to the glass cover plate 22 to ensure that the camera can obtain a maximized field of view, reducing the image field of view limitation caused by the distance. The inclined surface on the inner side of the edge of the rectangular window 11 forms a glue filling channel 13, allowing the gap to be filled with sealant during the installation process, thereby strengthening the sealing between the rectangular window 11 and the glass cover plate 22.

[0061] In this embodiment, the interior of the cylinder 1 is provided with an antenna component accommodating groove 14, a rectangular groove 15 and a connecting port 16 in sequence from top to bottom along the axis direction of the cylinder 1; the U-shaped heat sink 21 is arranged in the rectangular groove 15, and forms an insect entry channel 17 with the side wall of the cylinder 1 with insect holes; the reasonable partitioning of the internal space of the device is realized, which not only makes the position of each functional module clearer, but also facilitates installation and maintenance, and improves the compactness and efficiency of the overall structure. The wireless communication component 4 is placed in the accommodating groove 14 and connected to the top of the U-shaped heat sink 21; the optimization of the antenna position reduces the possibility of signal interference, improves the quality and reliability of data transmission, and is particularly suitable for application scenarios that require real-time transmission of a large amount of image data. The connecting port 16 is detachably connected to the conical head 5, and the trap 51 is installed in the conical head 5. Further, the conical head 5 is a hollow structure, and the inner side wall of its top is provided with a sink, and the trap 51 is detachably installed inside the conical head 5 through the sink. The design of the sink enables the trap 51 to be installed inside the conical head 5 in a stable manner, which not only reduces the looseness or displacement of the trap 51 that may occur during use, but also enhances the stability of the overall structure. The trap 51 can be quickly installed and disassembled through the sink, and the user can easily replace different types of traps 51 according to different pest types or monitoring needs. The trap 51 can be easily removed from the conical head 5, and technicians can more easily clean or inspect the inside of the trap 51. It is also conducive to regularly replacing the attractant or other consumables in the trap 51 to maintain the best working condition and reduce the difficulty of maintenance.

[0062] Furthermore, a limiting plate 3 is provided between the rectangular groove 15 and the connection port 16, and the bottom base plate 23 of the U-shaped heat sink 21 is in contact with the limiting plate 3; the limiting plate 3 supports the bottom base plate 23 of the U-shaped heat sink 21, thereby ensuring the stable installation of the entire internal component and preventing the displacement of the internal component due to vibration or impact. A hollow hole is provided in the middle of the limiting plate 3, and the third camera 27 shoots the trap 51 through the hollow hole; the hollow hole in the middle of the limiting plate 3 is precisely aligned with the trap 51, so that the third camera 27 can directly shoot the scene in the trap 51 clearly through the hollow hole. A gap is left between the limiting plate 3 and the side wall of the cylinder 1, and the insect inlet channel 17 is connected to the trap 51 through the gap.

[0063] In this embodiment, the wireless communication component 4 includes an antenna seat 41 and at least two wireless antennas 42. The antenna seat 41 is provided with an antenna mounting slot and a battery mounting slot 411. The antenna mounting slot is used to install the wireless antenna 42, and the battery mounting slot 411 is used to install the battery. The antenna seat 41 not only integrates the antenna mounting slot and the battery mounting slot 411, but also can serve as a supporting structure for the entire wireless communication component 4, thereby enhancing the modularity of the system. It can be seen that the battery mounting slot 411 of the wireless communication component 4 is used to install the battery, so that the monitoring device can operate independently without an external power supply, especially in places where the power supply is unstable or difficult to access the power supply. The bottom of the antenna seat 41 is provided with a threading hole, and the wireless antenna 42 is electrically connected to the circuit board 24 through the threading hole; the threading hole at the bottom of the antenna seat 41 allows the wireless antenna 42 to be electrically connected to the circuit board 24 through the hole, which not only simplifies the internal wiring, but also reduces the risk of wires being exposed to the outside, and reduces the possibility of failures caused by line problems. A protective cover 6 is detachably installed on the top of the cylinder 1, and the protective cover 6 is arranged on the outside of the wireless communication component 4; the protective cover 6 detachably installed on the top of the cylinder 1 is arranged on the outside of the wireless communication component 4, providing physical protection to prevent the external environment (such as dust, moisture, mechanical shock) from damaging the antenna and the antenna seat 41.

[0064] The present invention also provides an insect pest image processing system, comprising: an image acquisition module, a preprocessing module, a feature extraction module, a classification module, a post-processing module, a data transmission module, a result display module and an early warning push module.

[0065] Among them, the image acquisition module adopts the wide-angle shooting component 2 of the grain silo insect monitoring device described in the above scheme, including a first camera 25, a second camera 26 and a third camera 27, to obtain high-definition pictures in real time.

[0066] The preprocessing module performs preprocessing on the collected images, including operations such as image cropping, scaling, and denoising. Image cropping is used to remove unnecessary background information and focus on the core area of ​​pest activity; scaling is used to adjust the image size to maintain consistency and efficiency in subsequent processing; denoising is used to reduce image noise caused by environmental factors (such as light changes, dust, etc.), improve image quality, and ensure the accuracy of feature extraction.

[0067] The feature extraction module uses a convolutional neural network to extract features from the image. The convolution layer can capture the spatial structure of the image, and the pooling layer is used to reduce the dimension and retain the most important feature information. Through multi-layer convolution and pooling operations, the system can learn the morphological characteristics of pests, such as body shape, color, texture, etc. The sample library has diverse data sources, ensuring the comprehensiveness and generalization ability of model training.

[0068] The data in the sample library includes but is not limited to the following channels: Laboratory cultivation: Cultivating different types of stored grain pests in a controlled environment and taking high-resolution images to provide standard samples for the model. Field collection: Collecting pest samples in actual grain storage silos and taking on-site images to enable the model to adapt to changes in the real environment. Partner institutions: Cooperate with agricultural research institutions, universities and enterprises to share data resources and enrich the content of the sample library.

[0069] The sample library contains many types of pests and is continuously expanding to meet different identification needs. Through pest feature extraction, the main feature identification is as follows:

[0070] The corn beetle has a slender cylindrical body, thin antennae, a pronotum-shaped head, two prominent front horns, and a neck-like connection between the prothorax and the elytra;

[0071] Rice weevil: Oval in shape, reddish brown to asphalt in color, dull or slightly shiny on the back, with obvious spots on the head and a slender muzzle like an elephant's trunk;

[0072] Booklice: 1-3 mm long, yellowish-white or yellowish-brown in color, translucent, with enlarged abdomen and flat and swollen hind leg segments;

[0073] Moth: Wingspan is about 4 to 30 cm, wings, body and legs are covered with powdery scales, moth body is thicker and darker than butterfly;
