[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figure 1As shown, the first aspect of this embodiment provides a soybean stalk detection device, including a scanning chamber 1, a chuck 2, a Y-axis motion unit 3, a 3D scanning unit 4, an electric turntable 5, an electronic control unit 6, and a display 7. The scanning chamber 1 is a rectangular box structure with a storage cavity formed therein for accommodating the soybean stalks. The chuck 2, the Y-axis motion unit 3, the 3D scanning unit 4, the electric turntable 5, and the electronic control unit 6 are all installed in the storage cavity, and the Y-axis motion unit 3, the 3D scanning unit 4, the electric turntable 5, and the display 7 are respectively electrically connected to the electronic control unit 6 for controlling the scanning process.

[0023] The device placement plane is defined as the X-axis direction, and the Y-axis motion unit 3 is positioned perpendicular to the X-axis. The Y-axis motion unit 3 is positioned within the receiving chamber along the height of the scanning chamber 1. The 3D scanning unit 4 is mounted on the Y-axis motion unit 3 and drives the 3D scanning unit 4 to move back and forth along the Y-axis direction. The electric turntable 5 is mounted at the bottom of the scanning chamber 1. The scanning chamber 1 provides a stable mounting base for the electric turntable 5 and also provides some protection, reducing the impact of external factors such as dust and debris on the electric turntable 5, ensuring its operational stability and reliability, and thus ensuring the smooth progress of the seed testing process. The chuck 2 is fixedly mounted on the top of the electric turntable 5 and is used to secure the soybean stalk. The chuck 2 is coaxial with the rotation axis of the electric turntable 5. When the electric turntable 5 rotates, it can drive the chuck 2 to rotate 360 degrees, ensuring the concentricity of the soybean stalk fixed to the chuck 2 during rotation, preventing eccentric sway of the stalk during rotation, and thus ensuring the accuracy and reliability of the data collected by the 3D scanning unit 4. Furthermore, the axial direction of the rotation axis of the electric turntable 5 is the Y-axis direction, that is, the rotation axis of the electric turntable 5 and the extension direction of the Y-axis motion unit 3 are parallel to each other, so that the vertical movement of the 3D scanning unit 4 and the rotation of the stem can be precisely coordinated, ensuring that every point on the surface of the stem can be scanned by the 3D scanning unit 4, avoiding morphological distortion and data loss due to viewing angle deviation.

[0024] The display 7 is detachably mounted on the outside of the scanning chamber 1 to display the collected image data and analysis results, so that the operator can obtain test-related information intuitively and clearly.

[0025] During actual use, the operator first secures the stem to the chuck 2. Next, the electronic control unit 6 controls the electric turntable 5, which drives the chuck 2 and rotates the stem 360 degrees. Simultaneously, the Y-axis motion unit 3 drives the 3D scanning unit 4 up and down, scanning the stem in all directions and collecting data. Throughout this process, each unit works collaboratively, and data is transmitted in real time to the electronic control unit 6 for processing and analysis. The processed data is displayed on the display 7, allowing the operator to view the stem image and other analysis results at any time.

[0026] Through the above technical solution, the electric turntable 5 is controlled by the electronic control unit 6 to drive the chuck 2 to rotate 360 degrees, and the 3D scanning unit 4 on the Y-axis motion unit 3 is cooperated to realize all-round imaging scanning of the soybean stems, which can accurately obtain the appearance and internal characteristic information of the stems, and improve the accuracy of the stem phenotypic analysis; at the same time, the automated seed testing process greatly reduces manual intervention, significantly shortens the seed testing time, and improves the seed testing efficiency; it solves the problem that the traditional seed testing method is inefficient and easily interfered by subjective factors, and is difficult to meet the high-throughput and multi-dimensional data needs of precision agriculture.

[0027] It should be noted that "360-degree rotation" here means that the chuck 2 drives the stem to rotate in a complete circle around its own axis, so that the sides of the stem can face the 3D scanning unit 4 in turn, thereby realizing all-round imaging scanning without blind spots.

[0028] In some embodiments, the Y-axis motion unit 3 includes at least one of a track device, a multi-degree-of-freedom robotic arm, or a telescopic rod, which is used to drive the 3D scanning unit 4 to move along the height direction of the stem. In this embodiment, taking the track device as an example, the 3D scanning unit 4 is set on the track device through a slider that can slide with the track. In this way, the 3D scanning unit 4 obtains the ability to move accurately along the height direction of the scanning chamber 1. Under the guidance and support of the track, the 3D scanning unit 4 can slide up and down smoothly and uniformly in the scanning chamber 1 according to the preset program or actual detection needs. Whether it is a short and tender stem seedling or a tall and mature stem plant, a complete scan of the full height range of the stem can be achieved from top to bottom, or from bottom to top, through movement in the Y-axis direction.

[0029] In other embodiments, the Y-axis motion unit 3 may be a robotic arm with multiple degrees of freedom, capable of multiple motions such as pitch, rotation, and telescoping. The advantage of a robotic arm is that it can achieve high-precision positioning, ensuring that the 3D scanning unit 4 remains precisely positioned at any height and angle within the scanning chamber 1, while also being able to move horizontally along the stem. Harmonic reducers and cross-roller bearings can be used at the joints of the robotic arm to support the weight of the 3D scanning unit 4 while reducing vibration during movement, thereby avoiding image capture distortion caused by shaking.

[0030] Alternatively, a telescopic rod structure can be used. This structure typically consists of multiple nested metal tubes with a built-in ball screw and linear guide. A stepper motor drives the screw, which in turn rotates the rod, moving it smoothly along the height of the stalk being scanned, and it can self-lock at any position.

[0031] In short, the design can be made according to actual needs and no restrictions are made here.

[0032] In some embodiments, the 3D scanning unit 4 includes an imaging device and a light source. The imaging device includes at least one of a visible light camera, a near-infrared camera, a multispectral camera, a hyperspectral camera, a thermal infrared camera, a lidar, or an X-ray detector. The light source includes at least one of a natural light source, an LED light, or a halogen lamp. During operation, the imaging device uses the light source to comprehensively collect and capture images of the stem phenotype, providing rich and accurate data support for stem detection. It is worth mentioning that halogen lamps are an ideal light source. Due to their high color rendering index, they can accurately restore the true color of the stem, ensuring that the image captured by the imaging device is color-free. Halogen lamps are typically equipped with a parabolic reflector or an ellipsoidal reflector cup. Using geometric optics, the divergent light emitted by the filament is converged and adjusted into parallel light or a fan-shaped beam at a specific angle. For example, the inner wall of the reflector is treated with a micron-level coating (such as aluminum or silica), with a reflectivity of over 95%, ensuring that light is evenly reflected onto the surface of the pod. Its stable luminous performance and uniform light distribution, when working with imaging equipment, can effectively avoid the difference in image brightness and darkness caused by uneven lighting, provide high-quality lighting conditions for imaging equipment, thereby ensuring the accuracy and completeness of stem image acquisition and improving the reliability of seed testing data.

[0033] It is understood that imaging equipment can flexibly combine visible light cameras, near-infrared cameras, multispectral cameras, hyperspectral cameras, thermal infrared cameras, lidar, X-ray detectors, and other devices based on actual testing needs, without any limitation here. Visible light cameras record the appearance and morphology of stems, such as color, surface texture, leaf size and shape, and stem thickness. By capturing high-definition images, they can be used to observe the growth status of stems, identify the presence of diseased spots, yellowing, or damage on leaves, and identify bent or broken stems, providing basic visual information for preliminary assessment of stem health and growth environment. Near-infrared cameras utilize the strong penetrating power of near-infrared light to detect moisture content, cellular structure, and biochemical composition within stems. Multispectral cameras capture spectral information in multiple specific narrow bands. By analyzing the differences in stem reflectivity across these bands, they can identify stem type and growth stage, as well as the extent of pest and disease infestation. Hyperspectral cameras, with their extremely high spectral resolution, can capture continuous and detailed spectral curves, enabling more in-depth chemical composition analysis and substance identification within the stems. Thermal infrared cameras, based on the principle of thermal radiation, detect temperature distribution on the surface of the stem. By analyzing temperature differences, the physiological state of the stem can be determined and hidden pests and diseases can be discovered. LiDAR constructs a three-dimensional point cloud model of the stem by emitting a laser beam and receiving the reflected signal, accurately capturing the spatial structural information of the stem, including plant height, canopy morphology, and spatial distribution of the stem. X-ray detectors utilize the penetrating properties of X-rays to detect structural defects, cavities, or foreign matter within the stem. Based on different testing requirements, multiple devices can be used in collaboration to comprehensively collect multimodal stem data, from the exterior to the interior, from two-dimensional planes to three-dimensional space, providing a scientific basis for precise soybean testing.

[0034] In some embodiments, the electronic control unit 6 includes a power supply, a microcomputer and a PLC controller, and the three are electrically connected. The power supply is used to connect to an external power supply line to provide stable power for the microcomputer, the PLC controller and each functional unit. The microcomputer conducts an in-depth analysis of data such as the multispectral images of the stems collected by the imaging equipment, and intuitively presents the analysis results on the display 7, providing accurate data support for the operator's decision-making. Based on a preset program, the PLC controller cooperates with the Y-axis motion unit 3 and the electric turntable 5 according to the needs of the 3D scanning unit 4 to achieve multi-angle and full-dimensional scanning of the stems. The PLC controller ensures the efficiency of the entire detection process and greatly improves the automation and intelligence level of the detection.

[0035] In some embodiments, a door 101 that can be opened or closed is provided on one side of the scanning chamber 1. This design facilitates the insertion and removal of soybean stalks. Operators can easily place stalks into the scanning chamber 1 and remove them after scanning, enhancing operational convenience. Furthermore, during equipment maintenance, calibration, or troubleshooting, opening the door 101 allows direct access to internal components, significantly improving maintenance efficiency and making the daily management and use of the scanning chamber 1 more flexible and efficient, providing reliable assurance for the continued and stable performance of soybean stalk inspections.

[0036] like Figure 2-3 As shown, another aspect of the present invention proposes a portable soybean stalk seed testing device, including the soybean stalk seed testing device proposed in the first aspect, and also includes an equipment body 8, a stalk scanning platform 10, a stalk scanning camera 12, an image processing unit and a control button 13. The equipment body 8 is a cabinet-type structure, and a movable wheel 9 is provided at the bottom. There are four movable wheels 9, which are respectively arranged at the four corners of the bottom of the equipment body 8. This design allows the weight borne by the device to be evenly distributed, thereby enhancing the stability of the overall structure.

[0037] Furthermore, the mobile wheels 9 are universal wheels with brakes. This ensures the device remains stable during scanning, preventing data collection deviations caused by minor external interference. It also facilitates flexible movement and fixation in complex terrain (such as uneven fields). Furthermore, the universal wheel structure allows for easy adjustment of the device's direction, reducing the difficulty of transport.

[0038] Furthermore, the moving wheels 9 can be made of high-friction material to enhance ground adhesion, prevent the equipment from accidentally sliding on slopes or in slippery environments, and improve operational safety.

[0039] The stalk scanning platform 10 can be folded and arranged on one side of the device body 8, and the upper surface of the stalk scanning platform 10 is covered with a black translucent acrylic cover 11. The stalk scanning platform 10 includes multiple plates, which are rotatably connected by bearing joints, and the side of the plate close to the device body 8 can also be rotatably connected to the device body 8 by bearing joints. In this way, when idle, the operator can use the bearing joints to fold the multiple plates in order and place them close to the device body 8. In this way, the overall volume of the stalk scanning platform 10 is greatly reduced, which not only effectively reduces the space occupied by the device when stored, but also brings great convenience to the transportation process of the device. In actual use, the folded plates are pulled apart, and the plates are gradually unfolded and finally flattened into a complete and stable plane by the rotation of the bearing joints, providing a solid and reliable foundation for scanning the stalks, ensuring that the stalks can remain in a stable position during the scanning process, and avoiding the accuracy of the scanning results affected by the shaking or unevenness of the platform.

[0040] Furthermore, when folded and stowed, the stalk scanning platform 10 is flush with the side of the device body 8, making the overall appearance of the device more neat and beautiful. Furthermore, this flush design reduces the accumulation of dust and debris on the device surface, helping to keep the device clean and maintain stable performance. This also minimizes the space occupied by the entire device when not in use, making it more convenient to store, reducing space waste and improving storage efficiency.

[0041] The stalk scanning camera 12 is located on the upper portion of the device body 8 and on the same side as the stalk scanning platform 10. The stalk scanning camera 12 has high-resolution and multispectral imaging capabilities. The stalk scanning camera 12 can include at least one of a visible light camera, a near-infrared camera, a multispectral camera, a hyperspectral camera, a thermal infrared camera, a lidar, or an X-ray detector. The actual functions and effects of the visible light camera, near-infrared camera, multispectral camera, hyperspectral camera, thermal infrared camera, lidar, or X-ray detector have been described above and will not be repeated here.

[0042] It's worth noting that high resolution combined with multispectral imaging can simultaneously capture both morphological characteristics (such as internode length and diameter) and physiological status (such as chlorophyll content and water distribution) of stems, enabling comprehensive analysis of phenotypic parameters. Multispectral signatures can also automatically identify areas of pest and disease infestation, providing data support for early warning.

[0043] Furthermore, the stalk scanning camera 12 can scan the stalks by emitting and receiving light in specific wavelength bands (such as visible light and near-infrared light). This multi-wavelength scanning allows for precise measurement of stalk appearance characteristics such as length, diameter, and color uniformity. For example, visible light can clearly capture stalk color changes, subtle surface textures, and damage, providing comprehensive and accurate data support for evaluating stalk appearance quality. Furthermore, by combining light reflection and transmission information from different wavelengths, this scanning technology enables in-depth analysis of the stalk's internal structure. For example, near-infrared light can penetrate the stalk surface to detect its internal moisture content and fiber structure. This deep detection capability enables the device to proactively detect pests and diseases within the stalk, providing early warning for agricultural production. In short, by emitting and receiving light in specific wavelength bands, comprehensive detection of soybean stalk morphological characteristics and surface color can be achieved. This provides more comprehensive and in-depth data support for agricultural production, helping to promote the modernization and precision agriculture development.

[0044] The black translucent acrylic cover 11 is an integrated design, with one end tightly covering the stem scanning platform 10, and the other end extending upward and wrapping the stem scanning camera 12 located on the upper part of the device body 8, thereby forming a closed detection space. The black translucent acrylic cover 11 can absorb ambient stray light and prevent excessive background reflected light from interfering with the scanning results. At the same time, it allows the light bands required for near-infrared, multi-spectral and other detection bands to pass through, improving the signal-to-noise ratio of the scanned image, significantly improving the recognition accuracy of stem features (such as disease and pest spots, fiber structure), and improving the accuracy of detection data. The translucent setting can scatter some light, reduce direct reflection of light, and thus improve the scanning quality.

[0045] The image processing unit, integrated into the electronic control unit 6, analyzes scanned data and outputs feature information. Specifically, its integration into the microcomputer within the electronic control unit 6 achieves a high degree of hardware integration and reduces the device size. Furthermore, through image recognition algorithms and data analysis models, the entire process from data acquisition to feature extraction can be completed in real time, significantly improving detection efficiency.

[0046] The control button 13 is provided on the front of the cabinet and is electrically connected to the electric control unit 6 for controlling the operation of the device. The operator starts, pauses or adjusts the operation state of the device through the control button 13.

[0047] During actual use, move the device to a suitable testing site and ensure the ground is flat. Turn on the device power, press the control button 13, and initialize the device settings, including scanning parameters (such as scanning resolution, scanning band, etc.) and image display parameters. Check that the stalk scanning camera 12 is functioning properly and, if necessary, calibrate the camera. At the same time, unfold the folded stalk scanning platform 10 to form a complete, stable surface. Then, select the soybean stalk to be tested and place it on the stalk scanning platform 10, ensuring that the stalk is completely within the field of view of the stalk scanning camera 12. Place one end of a black translucent acrylic cover 11 over the stalk scanning platform 10, and extend the other end upward to wrap around the stalk scanning camera 12. Then, control the device operation using the control button 13. The stalk scanning camera 12 performs a full-scale scan of the stalk by emitting and receiving light in specific wavelengths. The light reflection and transmission information captured by the stalk scanning camera 12 is converted into electrical signals and transmitted to the image processing unit within the device. The image processing unit processes and analyzes the electrical signals to obtain the stalk's external characteristics (such as length, diameter, and color uniformity) and internal characteristics (such as moisture content, pest infestation, and fiber structure). The data analyzed by the image processing unit is displayed on the display 7 as intuitive images and data reports, allowing operators to view them in real time.

[0048] In some embodiments, the device body 8 is further provided with a network interface or storage interface for transmitting data to a cloud server or external device. This configuration not only enables real-time data sharing and remote monitoring, but also facilitates long-term data storage, subsequent analysis, and traceability, providing a more reliable basis for breeding decisions.
