Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, specifically a tool for photographing benthic organisms. Background Technology

[0002] Benthic organisms are those that inhabit the bottom or surface of marine or inland waters. They are an important ecological type of aquatic life, playing a crucial role in the material cycling and energy flow of aquatic ecosystems. They are also important indicator organisms for environmental monitoring and biodiversity research. Therefore, the accurate identification, classification, and examination of benthic organisms are a fundamental and critical task in marine and freshwater biology, environmental science, and ecology research. In such research, obtaining clear, accurate, and comparable biological sample image data is essential. Currently, the following method is commonly used when photographing benthic organism samples: the sample is taken out of the collection container and placed directly on a simple shooting platform (such as a petri dish, whiteboard, or temporary table), and the operator takes photos freely by holding the camera or using a simple tripod. However, existing shooting methods have many inherent defects, making it difficult to guarantee the consistency and scientific nature of the shooting quality. Relying on laboratory overhead lights or handheld light sources, they are prone to reflections, shadows, or underexposure / overexposure, resulting in distorted sample colors and loss of details. Due to the lack of dedicated shooting equipment, the relative position of the sample and the camera during each shooting depends on the operator's experience and intuition, which leads to inconsistent image quality and seriously affects the accuracy of subsequent identification and inspection. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a benthic organism imaging tool to enable rapid, stable, standardized, and high-quality imaging of benthic organisms in the laboratory, ensuring that the acquired image data meets the high standards of accuracy, consistency, and repeatability required by scientific research.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a benthic organism imaging apparatus, comprising: The base has a column fixedly installed on top of it; The guide plate is fixedly installed on the column; Two sliders are slidably disposed on the front wall of the guide plate in a vertical direction; Connecting plate one and connecting plate two are respectively fixedly mounted on the two sliders; The camera is fixedly mounted at one end of the connecting plate. A ring-shaped planar light source is fixedly mounted at the end of the second connecting plate; A detection groove is formed on the upper surface of the base to accommodate benthic organisms; The vertical projection of the camera is located within the central hole of the annular planar light source, and the center of the detection slot is vertically aligned with the axis of the annular planar light source and the optical axis of the camera.

[0005] Preferably, a guide rail is fixedly provided on the surface of the guide plate, and a groove matching the guide rail is provided on the slider. The cross-section of the guide rail and the groove is dovetail-shaped.

[0006] Preferably, a rack is fixedly mounted on the guide rail, a gear that meshes with the rack is rotatably mounted inside the slider, and a knob connected to the gear is provided on one side of the slider.

[0007] Preferably, a clamping block is slidably disposed in the groove, and a threaded rod is threadedly connected to the other side of the slider. One end of the threaded rod is rotatably connected to the clamping block, and an operating rod is fixedly installed at the other end of the threaded rod.

[0008] This utility model provides a tool for photographing benthic organisms, which has the following beneficial effects: Improved imaging quality and stability: By setting up a dedicated detection slot and precisely aligning the center of the detection slot with the optical axis of the camera and the axis of the ring light source, the sample is always in the optimal shooting position, effectively avoiding image blurring caused by sample offset and shaking, and providing stable and clear images for morphological identification; Achieving uniform, shadowless illumination: A ring-shaped planar light source is used, and the camera can be placed in the center of it. The light can evenly illuminate all angles of the benthic organism sample, minimizing shadows and reflections, so that the surface texture, color and other features of the sample can be captured realistically and clearly. Independent fine adjustment: The camera and the ring light source are height-adjusted through an independent slider mechanism, which can achieve both synchronous coarse adjustment and fine individual focusing (camera) and supplementary lighting (light source). The operation is flexible and convenient, and can quickly adapt to samples of different sizes and reflective properties to achieve the best shooting effect. Ensuring standardized and repeatable operation: The entire tooling structure fixes the relative geometric relationship of the shooting (vertical light path, center alignment), and through scales or quantifiable adjustment mechanisms (such as gears and racks), the images taken by different times and by different people have a high degree of consistency and comparability in terms of angle, scale and lighting, which greatly improves the accuracy and repeatability of scientific research data. Stable structure and easy to carry: This utility model has a compact structure and high integration. The components are fixedly connected to form a stable whole, avoiding cumbersome on-site debugging. At the same time, compared with large imaging systems, this tooling is small in size, requires no complicated installation process, and is easy to move or carry between different laboratory workbenches, meeting the need for flexible use in scientific research.

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] Please see Figures 1-3 This utility model provides a technical solution: a benthic organism imaging fixture, including a base 1, a column 2 fixedly mounted on the base 1, a guide plate 3 fixedly mounted on the column 2, two sliders 5 that can slide vertically on the front wall of the guide plate 3, a connecting plate 6 and a connecting plate 8 fixedly mounted on the two sliders 5 respectively, wherein a camera 7 is fixedly mounted at the end of the connecting plate 6, and an annular planar light source 9 is fixedly mounted at the end of the connecting plate 8. The height of the camera 7 and the annular planar light source 9 can be adjusted by moving the two sliders 5 respectively, so as to realize the vertical position adjustment of the two, and the camera 7 can be inserted into the central hole of the annular planar light source 9. A detection groove 17 for placing benthic organisms is opened on the upper surface of the base 1. The center of the detection groove 17 is vertically aligned with the axis of the annular light source and the optical axis of the camera 7, so as to facilitate the vertical alignment of the benthic organisms with the camera 7 and the light source. As an embodiment of this utility model, a guide rail 4 is fixedly provided on the surface of the guide plate 3, and a slide groove 13 matching the guide rail 4 is provided on the slider 5. The cross-sections of the guide rail 4 and the slide groove 13 are dovetail-shaped. As an embodiment of this utility model, a rack 11 is fixedly provided on the guide rail 4, and a gear 12 that meshes with the rack 11 is rotatably provided inside the slider 5. A knob 10 connected to the gear 12 is provided on one side of the slider 5. Turning the knob 10 can rotate the gear 12. As an embodiment of this utility model, a clamping block 14 is slidably arranged in the groove 13, and a threaded rod 15 is threadedly connected to the other side of the slider 5. One end of the threaded rod 15 is rotatably connected to the clamping block 14, and an operating rod 16 is fixedly installed at the other end of the threaded rod 15. The operating rod 16 can be turned to rotate the threaded rod 15. When the threaded rod 15 rotates, it can move axially, thereby pushing the clamping block 14 to move linearly. The linear movement of the clamping block 14 clamps the guide rail 4, thereby fixing the slider 5 on the guide rail 4.

[0013] The working principle and usage process of this utility model are as follows: When in use, the benthic organism to be detected is placed in the detection tank 17, at which time the benthic organism is positioned directly below the camera 7 and the annular planar light source 9; the height of the two sliders 5 can be adjusted by rotating the knobs 10 on the two sliders 5 respectively, thereby controlling the height of the camera 7 and the annular planar light source 9; by adjusting the distance between the camera 7 and the benthic organism, the camera 7 can be focused, so as to transmit a clear image to the computer screen. When the display result on the computer screen is too dark or too bright, the brightness of the light source can be adjusted by adjusting the distance between the annular planar light source 9 and the benthic organism, so that the display content on the screen becomes clear.

[0014] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
