DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with embodiments, but the present invention is not limited to the following embodiments:

[0027] Embodiment 1:

[0028] like Figures 1 to 5As shown, a forest pest identification and monitoring device with an interference structure includes a first insect luring mechanism 2, a climbing net 3 and a first shooting device 4, wherein the climbing net 3 is located in the insect luring area of ​​the first insect luring mechanism 2, and the first shooting device 4 is used to shoot insects on the climbing net 3. It also includes an interference structure 5, and the interference structure 5 includes an induction tube 51. The induction tube 51 is provided with an interference device, and the interference device is used to interfere with insects so that the insects enter the induction tube 51 from the insect luring area of ​​the first insect luring mechanism 2, and also includes a second shooting device 52 for shooting insects in the induction tube 51.

[0029] In this embodiment, the first insect attracting mechanism 2 is used to attract insects in the surrounding environment, specifically, light or pheromone can be used for attracting, the clinging net 3 is used to provide a residence position for the insects lured to the insect attracting area, and the first shooting device 4 is used to take pictures of the insects staying on the clinging net 3, so as to classify the insects, count the number, and identify the individual characteristics of a large number of insects at the monitoring deployment point. This solution is aimed at the first insect attracting mechanism 2 using an insect attracting lamp, which can attract a large number of insects from the surrounding area. These insects not only have large species and individual differences, but are also arranged in a disorderly manner on the clinging net 3. At the same time, when this device is used in a forest area, the specific use location may have a problem of poor communication quality. At the same time, the same type of insects in different areas have differences in shape characteristics and color due to local climate and food characteristics, and a technical solution with an interference structure 5 is provided.

[0030] In the interference structure 5, the insects are interfered with so that after the insects enter the insect trapping area under the action of the first larvae mechanism, they partially enter the induction tube 51 under the interference. Compared with the relatively open insect trapping area of ​​the first larvae mechanism, the number of insects that can enter the induction tube 51 is less than the number of insects covered by the shooting area of ​​the first insect trapping mechanism 2. At the same time, the induction tube 51 can provide a relatively closed shooting environment, which enables the second shooting device 52 to take pictures of fewer insects in a relatively stable environment. In the obtained photos, the characteristics of individual insects are more clearly reflected. Compared with the photos obtained by the first shooting device 4, the photos obtained by the second shooting device 52 can be better used for insect classification and individual feature judgment. Specifically, the application is to use the photos obtained by the second shooting device 52, after grayscale processing, insect contour extraction, insect contour area image feature extraction, feature comparison to determine the insect species, the relevant features in the photos obtained by the second shooting device 52 and the relationship between the insect species associated with the features are used to establish a training set or a comparison database, and the training set or the comparison database is used for the classification of the species of insects photographed by the first shooting device 4.

[0031] In this way, the first camera 4 is used to collect data on insects in the monitoring environment, and the second camera 52 is used to identify insect species. Due to the existence of the interference structure 5, in order to achieve the purpose of insect species classification, the quality requirements of the photos taken by the first camera 4 are lower, and the photos obtained by the second camera 52 have a guiding role in the identification of insect species in the photos obtained by the first camera 4. This allows technical personnel in this field to improve the accuracy of monitoring environment insect classification with lower equipment costs and lower costs or requirements for photo data transmission or storage.

[0032] Taking the fall armyworm as an example, its morphology is similar to that of the sticky cutworm moth (the latter is thinner than the former), and the local food composition may also lead to smaller differences in body shape and color between the two. In this way, after the photos obtained by the second camera 52 are used to establish classifiers for each of them using body shape and color, the classifier can be used to classify and identify insects in the photos obtained by the first camera 4.

[0033] The above lists computer-based image recognition methods, but in specific implementation, it should be understood that the above is only an example. This solution provides a structural basis for realizing the above technical means. As for the monitoring device itself, it should be understood that: when the photos obtained by the second camera 52 and the first camera 4 are each used for manual classification and statistics, the information provided to the judgment personnel by the photos obtained by the second camera 52 can also be used to guide the processing of the photos obtained by the first camera 4.

[0034] To achieve the interference purpose, the interference structure 5 can utilize the shielding function formed by the induction tube 51, so that the insects randomly enter the induction tube 51 through the tube opening of the induction tube 51. Preferably, in order to achieve active interference or differentiated interference for different types of insects, the following technical solution is adopted to install a second insect trapping mechanism 54 on the induction tube 51.

[0035] The interference device is a second insect attracting mechanism 54 installed on the induction tube 51, and the second insect attracting mechanism 54 is an insect attractant releasing mechanism or an insect attractant light releasing mechanism. In the specific implementation of this preferred method, the insect attractant releasing mechanism is used to release insect attractant pheromones, and the insect attractant light releasing mechanism is used to release insect attractant light. This can not only improve the insect feature capture rate of the second shooting device 52, but also actively adopt different pheromones or insect attractant light wavelengths to strengthen the feature collection of specific types of insects. In this application, the number of the interference structures 5 is set to be multiple, and each interference structure 5 is provided with a second insect attracting mechanism 54. When using it, the user selects the second insect attracting mechanism 54 that selectively attracts the key focus object according to the characteristics of the control position.

[0036] As described in the above application, the insects at the controlled position are lured by the first insect luring mechanism 2, and a large amount of insect image data is collected by the first shooting device 4. Taking the black light lamp used in the first insect luring mechanism 2 as an example, a black light lamp with a power of tens of watts can cover a large insect luring area and attract a large number of insects. The functions of the second insect luring mechanism 54 and the second shooting device 52 do not require a large number of insects to enter the induction tube 51, so the size of the induction tube 51 does not need to be set larger, and the power requirement of the second insect luring mechanism 54 is also small. As a technical solution that can work for a long time, the heat generated by the second insect luring mechanism 54 when working is not easy to cause the ambient temperature in the induction tube 51 to rise, causing the insects to die in the induction tube 51 and causing the image quality obtained by the second shooting device 52 to deteriorate. The following preferred solution is adopted: the second insect luring mechanism 54 is an LED lamp that releases insect luring light, and also includes a light-transmitting plate 53 installed in the induction tube 51, and the light-transmitting plate 53 is located in the irradiation area of ​​the LED lamp, and the light-transmitting plate 53 is located in the shooting area of ​​the second shooting device 52. In specific implementation, the LED lamp is used to emit ultraviolet light. The LED lamp is installed on the wall of the induction tube 51. The heat dissipation structure of the LED lamp is located outside the induction tube 51. The LED lamp can play an attracting role for a long time without maintenance. The heat generated by the LED lamp can be dissipated in time without affecting the internal environment of the induction tube 51. The LED lamp is small in size and easy to install on the induction tube 51. At the same time, there is no time required for the heating of the black light lamp. Under the required photo shooting requirements, it has the characteristics of saving energy. The light-transmitting plate 53 is used. The light-transmitting plate 53 forms a light emitting module under the action of the LED lamp to increase the probability of insects clinging to the light-transmitting plate 53. When the second shooting device 52 is aimed at the clinging surface provided by the light-transmitting plate 53 for insects to shoot, the shooting quality of the second shooting device 52 can be effectively improved, and the accuracy of the device in insect classification can be guaranteed.

[0037] As described above, under the action of the second insect attracting mechanism 54, the scheme of using LED lamps is advantageous in terms of installation, energy consumption, and the effect of heat on insects compared to the scheme of using black light lamps. However, if the first insect attracting mechanism 2 uses a black light lamp that can be set to a relatively high power, and the LED lamp is another ultraviolet light source, this will increase the complexity of the structure and control of the device. In parallel with the above active luring scheme, the following scheme can be adopted: it also includes a light-transmitting plate 53 installed in the induction tube 51, and the light-transmitting plate 53 is located in the shooting area of ​​the second shooting device 52. The first insect attracting mechanism 2 includes a black light lamp and an optical path, and the optical path is used to guide the ultraviolet rays emitted by the first insect attracting mechanism 2 into the light-transmitting plate 53. In this scheme, the role of the light-transmitting plate 53 is the same as that of the light-transmitting plate 53 in the above scheme, except that: without using a separate second insect attracting mechanism 54, the ultraviolet rays emitted by the first insect attracting mechanism 2 are used to guide part of the ultraviolet rays to the light-transmitting plate 53 under the action of the optical path, so that the interference structure 5 can play an active interference role. It is very easy to implement and has a simple structure. The optical path can be optical fiber.

[0038] As described above, in the existing insect feature image picking process, a technical solution can be adopted to extract the insect outline in the image and then obtain the specific image features from the determined outline. The insect outline extraction can adopt a solution of first graying, performing background removal operation according to the graying result, and finally extracting the insect outline. In outdoor shooting, the number of insects in the induction tube 51, the arrangement of insects, the reflective characteristics of insects, and natural fill light will affect the difficulty and accuracy of insect outline extraction. Therefore, it is preferably configured as follows: a dividing strip 57 is provided on the light-transmitting plate 53, and the dividing strip 57 is a coating coated on the surface of the light-transmitting plate 53 or a dividing line pre-buried on the inner side of the light-transmitting plate 53. The dividing strip 57 divides the part of the light-transmitting plate 53 exposed in the shooting area of ​​the second shooting device 52 into multiple cells. By adopting the above scheme, the features formed by the dividing bar 57 in the imaging of the second shooting device 52 can be used to assist in the extraction of insect contours, such as directly eliminating the imaging area of ​​the complete cell in the photo, retaining the image of the covered cell area, retaining the image of the incompletely covered cell area and using the starting and ending positions of the dividing bar 57 to determine the insect contour area, which can effectively reduce the difficulty and accuracy of insect contour extraction.

[0039] Taking into account that the image formed during the flight of insects is used for species judgment, due to the unstable relative shooting angle and fewer available feature points, the difficulty is greater than that of the image formed during the crawling process. It is preferably configured as follows: the light-transmitting plate 53 is installed in a flat manner on the bottom surface of the inner wall of the induction tube 51, and the top surface of the light-transmitting plate 53 faces the lens of the second shooting device 52. It also includes a light-transmitting curtain 55 installed in the induction tube 51, and the bottom side of the light-transmitting curtain 55 and the bottom surface of the inner wall of the induction tube 51 have a channel 56 for insects to pass through, and the light-transmitting curtain 55 is located between the light-transmitting plate 53 and the entrance of the induction tube 51. In this solution, the top surface of the light-transmitting plate 53 is used as the insect climbing surface. Due to the existence of the light-transmitting curtain 55, the light-transmitting curtain 55 will not only not excessively affect the insects from entering the induction tube 51, but also hinder the insects from flying, so that the insects are adjusted to a climbing state to pass through the channel 56, and the insects in the climbing state can enter the side of the light-transmitting plate 53 through the channel 56 with a greater probability. In this way, the second shooting device 52 can shoot the insects in the climbing state from bottom to bottom with a greater probability, and achieve the purpose of facilitating the accuracy and reference of insect species identification from the perspective of insect morphological feature acquisition and color feature acquisition.

[0040] In the prior art, the power distribution range of black light lamps is large, which makes it convenient to select black light lamps with appropriate power according to specific needs to meet the requirements of the attraction range. In order to protect the first insect attracting mechanism 2, it is preferably configured as follows: it also includes a lampshade 1, and the first insect attracting mechanism 2 includes a black light lamp installed in the lampshade 1. The side wall of one side of the lampshade 1 is a light-transmitting cover 6, and the clinging net 3 is installed on the outer wall of the light-transmitting cover 6. When this solution is used in practice, the light-transmitting cover 6 is used as an isolation cover between the black light lamp and the clinging net 3 to prevent insects from entering the lampshade 1 and affecting the circuit and causing the black light output characteristics to decrease. When the clinging net 3 is attached to the surface of the light-transmitting cover 6, it can prevent individual smaller insects from passing through the holes of the clinging net 3, and eventually cannot escape and affect the ultraviolet light output.

[0041] When there are many insects staying on the clinging net 3, it will affect the surrounding insects to cling to the clinging net 3. After taking pictures of the insects on the clinging net 3, in order to actively drive away these insects and increase the possibility of other insects clinging to the clinging net 3, the purpose of improving the diversity of photos is achieved. It is set as follows: it also includes a vibration device installed on the lampshade 1, the vibration device is used to stimulate the vibration of the clinging net 3, and the vibration device adopts a polarization device. At the same time, in order to avoid the polarization conversion work affecting the life of the black light lamp, a simple structural solution is adopted to reduce the influence of the vibration device on the black light lamp: the vibration device is installed on the light-transmitting cover 6, the clinging net 3 is attached to the surface of the light-transmitting cover 6, and an elastic pad is arranged between the light-transmitting cover 6 and the lampshade 1. The two sides of the elastic pad are respectively bonded to the light-transmitting cover 6 and the lampshade 1, and the elastic pad adopts a rubber pad that can isolate vibration.

[0042] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific embodiments of the present invention are limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, other embodiments obtained without departing from the technical solution of the present invention should be included in the protection scope of the present invention.
