Description

Technical Field

[0001] The utility model relates to the field of mosquito monitoring, in particular to a device for collecting mosquito egg images of a mosquito and egg trap in multiple scenes, and is used for collecting and storing mosquito egg images after the mosquito and egg trap is recovered. Background Art

[0002] In the field of mosquito control, in order to collect samples of mosquito eggs in the area and measure the density of Aedes mosquitoes, mosquito egg traps are usually placed outdoors to attract mosquitoes to lay eggs, and then the egg traps are collected, and mosquito specimens are collected, and egg identification and counting are performed in the laboratory. A mosquito egg trap disclosed in the utility model patent CN 2648815Y is one of the most commonly used egg traps in the industry. It includes a transparent bottle body, a black bottle cap, and a bottle bottom protruding upward. A water-soaked filter paper placed at the bottom of the bottle is used to collect Aedes mosquito eggs. The identification and counting of eggs are the most critical tasks of this method. Taking the common Aedes albopictus as an example, its single egg is a shuttle shape of about 0.52mm*0.13mm, and is usually produced on the edge of the filter paper inside the mosquito egg trap. Because the eggs are too small and the filter paper is doped with other impurities (such as soil particles, plant fragments, other insects and their eggs, etc.), it is difficult to identify and count the eggs of Aedes albopictus by human eyes alone without the help of a stereoscope, a microscope or other tools. In order to solve the problem that the human eye cannot distinguish directly, the traditional method is to use tweezers to take out the filter paper with eggs, place it on a clean culture table, and use a stereoscope or microscope to manually identify and count the suspicious targets on the filter paper. However, manual operation requires high professional skills and there are subjective factors. In addition, because the stereoscope or microscope is not specifically used for the identification of the entire filter paper, its magnification is too large and only part of the filter paper can be displayed in the visual field. If you need to check whether the entire filter paper contains eggs, you need to move the filter paper repeatedly, which is time-consuming and will lead to repeated counting of the same eggs, and it is also easy to increase the risk of filter paper breakage. In addition, if you want to take pictures of the complete filter paper in each mosquito and egg trap and record the results, using a mobile phone camera to take pictures directly cannot ensure that the shape and texture of the eggs are clearly identifiable. With the help of a stereoscope or microscope, you cannot directly obtain the full picture of the filter paper, and it is difficult to make efficient and reliable backups of the mosquito and egg trap results.

[0003] In summary, the current field still lacks special equipment for the identification and counting of eggs in mosquito egg traps. The characteristics of eggs and the various properties of mosquito egg traps have put forward high requirements for process design and recording equipment. In addition, with the development of computer technology and the widespread application of machine learning and deep learning, the use of machine vision to intelligently identify and count eggs is the future development direction. Such methods not only require a large number of egg images for training, but also target identification and counting based on egg images in subsequent practical applications. How to achieve efficient and reliable data collection is the first step to overcome. Therefore, how to design a device that can simplify the mosquito egg image collection process after the mosquito egg trap is retrieved, optimize the egg identification and counting work, and improve the standardization and reliability of industry operations are technical problems that technical personnel in this field urgently need to solve. The existing mosquito egg image collection methods have problems such as low collection efficiency, poor consistency of collection results, and high requirements for the collection environment. Utility Model Content

[0004] The purpose of the utility model is to provide a device for collecting mosquito egg images of mosquito egg traps in multiple scenarios in response to the deficiencies of the prior art. The device adopts an embedded fill light board and sets an industrial camera on the fill light board to form a mosquito egg image collection device for mosquito egg traps. The collection device includes two types of usage scenarios: portable and desktop. The portable device is mainly used in outdoor or non-fixed laboratory environments. The desktop device is mainly suitable for fixed laboratories. The device has a simple structure and is easy to disassemble and operate. It can be used in a variety of indoor and outdoor scenarios, effectively improving the efficiency and quality of mosquito egg image collection after the mosquito egg trap is recovered, optimizing egg particle identification and counting work, and having good application prospects. It effectively solves the problems of excessive magnification of the stereoscopic method, complex identification process, and difficulty in taking photos and recording during the manual identification and counting of eggs after the mosquito egg trap is retrieved when using mosquito egg traps to monitor Aedes.

[0005] The specific technical solution of the utility model is: a device for collecting images of mosquito eggs in mosquito and egg traps in multiple scenarios, which is characterized in that the device includes two types of usage scenarios: portable and desktop. The portable device is mainly used in outdoor or non-fixed laboratory environments, and the desktop device is mainly suitable for fixed laboratories. The device needs to achieve clear shapes, edges, and textures of the captured eggs.

[0006] The device includes an industrial camera, a macro lens, a data transmission interface, a fill light, a fill light board, a support vertical plate, and a bottom plate. The main structure of the device is composed of an industrial camera, a fill light board, and a macro lens. The industrial camera is provided with a camera buckle, a data transmission interface, and a camera lens bayonet. The fill light board is in a circular ring shape, and is provided with fill lights evenly distributed along the ring. The industrial camera is embedded in the slot of the fill light board and fixed by the camera buckle. The macro lens is connected to the camera lens bayonet on the industrial camera. The data transmission interface is connected to the industrial camera by a data cable. The fill light is embedded in the fill light board through a groove. The fill light board is connected and fixed to the plug of the support vertical plate through the groove. The support vertical plate is fixed to the bottom plate. The bottom plate is provided with a groove for placing mosquito and egg traps, and the groove is directly opposite to the bottom of the lens of the industrial camera. The industrial camera should have a resolution greater than 4096*4096px, a sensor size greater than 1 inch, black and white or color mode, an external storage card slot, and support for TF card or SD card.

[0007] The fill light panel is connected to the plug board of the supporting vertical plate through a groove. The supporting vertical plate is provided with a telescopic structure with adjustable height, and the other end is fixedly connected to the bottom plate.

[0008] The fill light is a constant-on type or a supplementary flash type light source, and effectively illuminates the bottom of the mosquito and egg trap or the flat filter paper. The constant-on type light source has an illumination greater than or equal to 0.125cd / m2. If it is a supplementary flash type light source, its flash index is greater than or equal to GN14.

[0009] The industrial camera needs to have a higher pixel to ensure that the 0.52mm*0.13mm spindle-shaped egg has at least 20 pixels on the long side, so that camera-side data backup can be achieved.

[0010] The macro lens must have a focal length of 24mm to 105mm, a minimum aperture of at least F16 (no requirement for maximum aperture), a minimum focusing distance of less than or equal to 0.15m, a lens diameter of less than 7cm, and be able to support manual or automatic focus.

[0011] The macro lens should meet the needs of close-up photography. No matter whether the lens is inside or outside the mosquito egg trap bottle, the framing should be sufficient to cover the entire filter paper range (at least 7cm*7cm) with a single scene, and have a variable or fixed aperture. In actual use, an aperture value less than F16 will be used to obtain a larger depth of field, ensuring that the eggs in various parts of the filter paper are in the focal plane in a non-flat state, and clear edges and textures can be captured.

[0012] The data transmission interface is USB Type A or Type C. The industrial camera is connected to a computer or mobile phone via a data cable, and the taken egg photos are transmitted to the smart device in real time.

[0013] If the fill light is of constant-on type, the illumination must be greater than or equal to 0.125cd / m2; if it is of supplementary flash type, the flash index must be greater than or equal to GN14. The fill light must effectively illuminate the bottom of the mosquito and egg trap or the removed flat filter paper; the fill light is distributed around the embedded slot of the camera, and the fill light board is embedded through the groove so that the light can directly illuminate the eggs on the filter paper.

[0014] The fill light board is provided with an embedded slot for installing and fixing an industrial camera, so that the camera lens can be stably fixed on the fill light board, and the camera lens can be stably placed just above the bottle mouth of the mosquito and egg attractant, with the lens part entering the bottle body or higher than the bottle body, so that stable shooting can be achieved to obtain clear pictures.

[0015] The support stand is provided with a plug plate for horizontally fixing the fill light board, and is fixed to a groove reserved in the fill light board. The retractable support stand device allows the distance between the camera lens and the mosquito and egg trap bottle to be adjusted in desktop mode.

[0016] The bottom plate should have a groove reserved for placing mosquito and egg attractants, and the groove should be directly opposite to the bottom of the industrial camera lens, which is convenient for fixing the placement of the egg attractant in the work process. If the filter paper in the egg attractant needs to be taken out, the filter paper can also be spread flat in the groove to facilitate alignment of the filter paper with the camera field of view. The weight of the bottom plate should be sufficient to ensure that the device can remain stable after hanging the fill light and the camera lens.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects and significant technical progress:

[0018] 1) High efficiency and high precision in egg identification and counting

[0019] By using a high-pixel industrial camera combined with a macro lens, the utility model can capture clear egg shapes, edges and textures, ensuring the accuracy and reliability of mosquito egg identification and counting. This is faster than traditional manual identification methods and reduces subjective errors, especially in the identification of tiny Aedes albopictus eggs (about 0.52mm*0.13mm), which has obvious advantages.

[0020] 2) Flexibility to adapt to multiple scenarios

[0021] The device is designed to be portable and desktop, which can meet the needs of outdoor field work and laboratory. This makes the collection of mosquito egg images not restricted by location, improving the flexibility and efficiency of the work.

[0022] 3) Simplify the operation process and reduce professional requirements

[0023] The use of this device reduces the complicated operation steps and no longer requires the use of professional stereoscopes or microscopes for identification and counting. Compared with traditional methods, it greatly reduces the professional skill requirements for operation, allowing more technicians to quickly get started and improve work efficiency.

[0024] 4) Realize efficient data collection and backup

[0025] Through the data transmission interface, the industrial camera can transmit the captured mosquito egg images to a computer or smart device in real time, or directly store them in a TF card or SD card, which is convenient for fast data processing and backup. This not only ensures the immediate availability of data, but also increases the security and convenience of data management. BRIEF DESCRIPTION OF THE DRAWINGS
