[0039] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0040] As Figure 1 shown, the first aspect of the present embodiment provides a kind of soybean stalk's examination device, including scanning bin 1, chuck 2, Y axis movement unit 3, 3D scanning unit 4, motorized turntable 5, electric control unit 6 and display 7.Scanning bin 1 is the rectangular box structure with accommodating cavity in the inside, for accommodating soybean stalk.Chuck 2, Y axis movement unit 3, 3D scanning unit 4, motorized turntable 5 and electric control unit 6 are all installed in accommodating cavity, and Y axis movement unit 3, 3D scanning unit 4, motorized turntable 5 and display 7 are respectively electrically connected with electric control unit 6, for controlling scanning process.

[0041] The device is placed in plane and defined as X axis direction, Y axis movement unit 3 is perpendicular to X axis setting.Y axis movement unit 3 is set in accommodating cavity along the height direction of scanning bin 1, 3D scanning unit 4 is set on Y axis movement unit 3, Y axis movement unit 3 can drive 3D scanning unit 4 to reciprocate along Y axis direction.Motorized turntable 5 is installed at the bottom of scanning bin 1, scanning bin 1 provides stable installation base for motorized turntable 5, also can play a certain protective effect to it, reduce the influence of external factors such as dust, sundries etc. on motorized turntable 5, ensure its stability and reliability of operation, further guarantee the smooth progress of examination process.Chuck 2 is fixedly installed at the top of motorized turntable 5, for fixing soybean stalk.At the same time, chuck 2 is coaxially arranged with the rotating shaft of motorized turntable 5, when motorized turntable 5 rotates, it can drive chuck 2 to rotate 360 degrees, ensure the concentricity of soybean stalk fixed on chuck 2 when rotating, avoid the eccentric shaking of stalk in the process of rotation, so as to ensure that the data collected by 3D scanning unit 4 is accurate and reliable.Further, the axis direction of the rotating shaft of motorized turntable 5 is Y axis direction, i.e. the rotating axis of motorized turntable 5 is parallel with the extension direction of Y axis movement unit 3, so that the vertical movement of 3D scanning unit 4 and the rotation of stalk can be accurately matched, ensure that each point on the surface of stalk can be scanned by 3D scanning unit 4, avoid the morphological distortion and data loss caused by angle deviation.

[0042] The display 7 is detachably mounted on the outside of the scanning bin 1, and is used to display the collected image data and analysis results, so that the operator can intuitively and clearly obtain the information related to the stem.

[0043] In actual use, the operator first fixes the stem on the chuck 2. Then, the electric control unit 6 controls the electric turntable 5 to drive the chuck 2 to rotate the stem by 360 degrees; at the same time, the Y-axis movement unit 3 drives the 3D scanning unit 4 to move up and down, and scans the stem in all directions and collects data. During the whole process, the units work cooperatively, and the data is transmitted to the electric control unit 6 in real time for processing and analysis. The processed data is presented on the display 7, and the operator can check the image of the stem and other analysis results at any time.

[0044] Through the above technical solution, the electric control unit 6 controls the electric turntable 5 to drive the chuck 2 to rotate by 360 degrees, and cooperates with the 3D scanning unit 4 on the Y-axis movement unit 3 to realize all-around imaging scanning of the soybean stem, so that the appearance and internal feature information of the stem can be accurately obtained, and the accuracy of stem phenotype analysis is improved. At the same time, the automatic stem examination process greatly reduces the manual intervention, significantly shortens the stem examination time, and improves the stem examination efficiency. The problem that the traditional stem examination method is inefficient and easily interfered by subjective factors, and is difficult to meet the demand of high-throughput and multi-dimensional data for precision agriculture is solved.

[0045] It should be noted that the "360-degree rotation" here refers to the complete circumferential rotation of the chuck 2 driving the stem around its own axis direction, so that the side surface of the stem can be in turn opposite to the 3D scanning unit 4, thereby realizing all-around imaging scanning without dead angle.

[0046] In some embodiments, the Y-axis movement unit 3 includes at least one of a track device, a multi-degree-of-freedom mechanical arm or a telescopic rod, for driving 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 arranged on the track device through a slider which can slide with the track, so that the 3D scanning unit 4 obtains accurate movement ability along the height direction of the scanning bin 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 bin 1 according to the preset program or actual detection demand. Whether it is a small and tender stem seedling or a tall and mature stem plant, the 3D scanning unit 4 can realize complete scanning of the stem in the whole height range through the movement in the Y-axis direction, from top to bottom or from bottom to top.

[0047] In other embodiments, the Y-axis movement unit 3 can adopt a mechanical arm, which is a multi-degree-of-freedom structure and has the ability of compound motion such as pitching, rotating and stretching. The advantage of the mechanical arm lies in that it can realize high-precision positioning, ensuring the accurate stay of the 3D scanning unit 4 at any height and angle in the scanning bin 1, and at the same time, it can also move along the horizontal direction of the stem. Harmonic reducers and cross roller bearings can be used at the joints of the mechanical arm, which can not only bear the weight of the 3D scanning unit 4, but also reduce vibration during movement, avoiding image acquisition distortion caused by shaking.

[0048] Or a telescopic rod structure can also be used, which is usually composed of multiple nested metal pipes, with built-in ball screws and linear guide structures. By driving the screw to rotate through a stepping motor, the telescopic rod can smoothly stretch and retract along the height direction of the stem to be scanned, and can be self-locked at any position.

[0049] In summary, the design can be made according to actual needs, and no limitation is made here.

[0050] 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 laser radar or an X-ray detector, and the light source includes at least one of a natural light source, an LED lamp or a halogen lamp. During work, the imaging device captures the image of the stem phenotype with the help of the light source, providing rich and accurate data support for stem detection. It is worth mentioning that as a light source, halogen lamp will be the ideal choice. With its high color rendering index characteristics, it can accurately restore the true color of the stem, ensuring that the image color captured by the imaging device is not distorted. Halogen lamps are usually equipped with parabolic reflectors or ellipsoidal reflector cups, which can converge and adjust the divergent light emitted by the filament into parallel light or a specific angle of fan-shaped light beam through geometric optical principles. For example: the inner wall of the reflector is treated with micron-level coating (such as aluminum or silicon dioxide), and the reflectivity can reach more than 95%, ensuring that the light is uniformly reflected to the surface of the pod. Its stable lighting performance and uniform light distribution, combined with the work of the imaging device, can effectively avoid the difference in light and shade caused by uneven light, providing high-quality lighting conditions for the imaging device, thereby ensuring the accuracy and integrity of the stem image acquisition and improving the reliability of the plant data.

[0051] It can be understood that the imaging device can be flexibly combined according to the actual examination needs, and the imaging device can include a visible light camera, a near-infrared camera, a multi-spectral camera, a hyperspectral camera, a thermal infrared camera, a laser radar, an X-ray detector, and the like, without any limitation. Among them, the visible light camera records the appearance form of the stem, such as color, surface texture, leaf size and shape, stem thickness and the like. Through shooting high-definition images, the growth state of the stem can be observed, whether the leaf has a disease spot, yellowing, damage, whether the stem is bent or broken, and the like, to provide basic visual information for preliminary judgment of the stem health condition and the growth environment. The near-infrared camera uses the characteristic that the near-infrared light has strong penetration ability to detect the water content, cell structure and biochemical component information inside the stem. The multi-spectral camera captures the spectral information of multiple specific narrow bands, and identifies the type and growth stage of the stem and detects the degree of pest infestation by analyzing the reflectivity difference of the stem under different wave bands. The hyperspectral camera has extremely high spectral resolution and can obtain continuous and fine spectral curves, and can perform more in-depth chemical component analysis and material identification on the stem. The thermal infrared camera detects the temperature distribution of the stem surface based on the principle of thermal radiation. By analyzing the temperature difference, the physiological state of the stem can be judged, and hidden pest hazards can be found. The laser radar emits a laser beam and receives the reflected signal to construct a three-dimensional point cloud model of the stem, and accurately obtains the spatial structure information of the stem, including the plant height, the crown shape, the spatial distribution of the stem and the like. The X-ray detector detects the internal structural defects, cavities or foreign matters of the stem by using the penetration of X-rays. According to different examination needs, the multi-device collaborative operation can be performed from the appearance to the inside, from the two-dimensional plane to the three-dimensional space, to collect the multi-modal data of the stem in all directions, and to provide a scientific basis for the accurate examination of soybeans.

[0052] In some embodiments, the electric 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 with the external power supply line to provide stable power for the microcomputer, the PLC controller and each functional unit. The microcomputer deeply analyzes the stem multi-spectral images and other data collected by the imaging device, and intuitively presents the analysis results on the display 7, to provide accurate data support for the decision of the operator. The PLC controller cooperates with the Y-axis motion unit 3 and the electric turntable 5 based on the preset program according to the needs of the 3D scanning unit 4 to realize multi-angle and full-dimension scanning of the stem. The PLC controller ensures the efficiency of the whole detection process, and greatly improves the automation and intelligent level of detection.

[0053] In some embodiments, one side of the scanning bin 1 is provided with an openable and closable bin door 101, and the design of the bin door 101 makes it more convenient to put and take out the soybean stems. The operator can easily put the stems into the scanning bin 1 and take them out after the scanning is completed, improving the convenience of operation. Moreover, when the equipment is maintained, calibrated or troubleshooting, the opening of the bin door 101 can directly contact the internal components, greatly improving the maintenance efficiency, making the daily management and use of the scanning bin 1 more flexible and efficient, and providing reliable protection for the continuous and stable detection of soybean stems.

[0054] As shown in Figures 2-3 Another aspect of the present application provides a portable soybean stem testing device, which comprises the soybean stem testing device of the first aspect, and further comprises a device main body 8, a stem scanning platform 10, a stem scanning camera 12, an image processing unit and a control button 13. The device main body 8 is of a cabinet type structure, and is provided with four mobile wheels 9 arranged at the four corners of the bottom of the device main body 8. This design makes the weight borne by the device evenly distributed, thereby enhancing the stability of the overall structure.

[0055] Further, the mobile wheels 9 are universal wheels with brakes. In this way, the device can be kept stable during scanning, avoiding data collection deviation caused by slight external force interference, and facilitating flexible movement and fixation in complex terrain (such as uneven ground in the field). At the same time, the universal wheel structure allows the device to be easily adjusted in direction, reducing the difficulty of carrying.

[0056] Further, the mobile wheels 9 can be made of high-friction material to enhance the ground adhesion and prevent the device from accidentally sliding on slopes or slippery environments, thereby improving the operation safety.

[0057] The stem scanning platform 10 can be foldably arranged on one side of the device main body 8, and the upper surface of the stem scanning platform 10 is covered with a black translucent acrylic cover 11. The stem scanning platform 10 comprises a plurality of plate members which are rotatably connected by bearing joints, and the side of the plate member close to the device main body 8 can also be rotatably connected with the device main body 8 by bearing joints. In this way, in the idle state, the operator can orderly fold the plurality of plate members by means of the bearing joints and place them close to the device main body 8. In this way, the overall volume of the stem scanning platform 10 is greatly reduced, which not only effectively reduces the space occupied by the device when it is stored, but also brings great convenience to the transportation process of the device. In the actual use link, the folded plate members are pulled apart, and the plate members are gradually unfolded and finally laid flat into a complete and stable plane by means of the rotation of the bearing joints, thereby providing a solid and reliable foundation for the scanning of the stems and ensuring that the stems can be kept in a stable placement state during the scanning process, avoiding the influence of the shaking or unevenness of the platform on the accuracy of the scanning results.

[0058] Further, the stem scanning platform 10 is flush with the side of the device body 8 in the folded and stowed state, making the overall appearance of the device more neat and beautiful, and the flush design reduces the accumulation of dust and debris on the surface of the device, helping to maintain the cleanliness and performance stability of the device. At the same time, it 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.

[0059] The stem scanning camera 12 is located on the upper part of the device body 8 and is located on the same side as the stem scanning platform 10, and the stem scanning camera 12 has high resolution and multispectral imaging functions. The stem 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 laser radar, or an X-ray detector. The actual role and effect of the visible light camera, the near-infrared camera, the multispectral camera, the hyperspectral camera, the thermal infrared camera, the laser radar, or the X-ray detector have been described in the foregoing, and will not be repeated here.

[0060] It is worth mentioning that the combination of high resolution and multispectral imaging function can simultaneously obtain the morphological characteristics (such as internode length, diameter) and physiological state (such as chlorophyll content, water distribution) of the stem, realizing comprehensive analysis of the phenotype parameters. At the same time, through the multispectral characteristics, the disease and pest infection area can be automatically identified, providing data support for early warning.

[0061] Further, the stem scanning camera 12 can emit and receive light of specific wavebands (such as visible light, near-infrared light, etc.) to complete the scanning of the stem. Through multi-waveband light scanning, the length, diameter, color uniformity, and other appearance characteristics of the stem can be accurately measured. For example, using visible light can clearly capture the color change of the stem, the fine texture and damage on the surface of the stem, thereby providing comprehensive and accurate data support for the appearance quality evaluation of the stem. At the same time, combined with the reflection and transmission information of light of different wavebands, this scanning technology can deeply analyze the internal structure of the stem. For example, near-infrared light can penetrate the surface of the stem to detect the water content and fiber structure inside. This deep detection capability enables the device to discover the disease and pest erosion inside the stem in advance, providing early warning for agricultural production. In summary, by emitting and receiving light of specific wavebands, comprehensive detection of the morphological characteristics and surface color of the soybean stem can be achieved. This provides more comprehensive and in-depth data support for agricultural production, which helps to promote the development of agricultural modernization and precision.

[0062] The black translucent acrylic cover 11 is designed in one piece, one end tightly covers the stem scanning platform 10, the other end extends upwards and wraps around the stem scanning camera 12 located at the upper part of the device main body 8, thereby forming a closed detection space. The black translucent acrylic cover 11 can absorb ambient stray light, avoiding excessive background reflected light from interfering with the scanning results. At the same time, it allows near-infrared, multi-spectral and other detection required waveband light to pass through, improving the signal-to-noise ratio of the scanned image, significantly improving the recognition accuracy of stem features (such as pest and disease spots, fiber structure), and improving the accuracy of detection data. The semi-transparent design can scatter part of the light, reducing direct reflection of light, thereby improving the scanning quality.

[0063] The image processing unit is integrated in the electric control unit 6 and is used to analyze the scanning data and output feature information. Specifically, the image processing unit is integrated in the microcomputer of the electric control unit 6, achieving high integration of hardware and reducing the size of the device. At the same time, through image recognition algorithms and data analysis models, the whole process from data acquisition to feature extraction can be completed in real time, significantly improving the detection efficiency.

[0064] The control button 13 is provided on the front of the cabinet and is electrically connected with the electric control unit 6, used to control the operation of the device. The operator starts, pauses or adjusts the running state of the device through the control button 13.

[0065] In actual use, the device is moved to a suitable detection site, ensuring that the ground is flat. Turn on the power of the device, open the control button 13, and initialize the settings of the device, including scanning parameters (such as scanning resolution, scanning waveband, etc.), image display parameters, etc. Check whether the stem scanning camera 12 is working normally, and if necessary, calibrate the camera. At the same time, unfold the stem scanning platform 10 to form a complete and stable plane. Then select the soybean stem to be detected, place the stem on the stem scanning platform 10, and ensure that the stem is completely within the field of view of the stem scanning camera 12. Cover one end of the black translucent acrylic cover 11 on the stem scanning platform 10, and extend the other end upwards to wrap the stem scanning camera 12. Then control the device to run through the control button 13, and the stem scanning camera 12 scans the stem in all directions by emitting and receiving specific waveband light. The light reflection and transmission information captured by the stem scanning camera 12 is converted into an electrical signal and transmitted to the image processing unit inside the device. The image processing unit processes and analyzes the electrical signal to obtain the appearance features (such as length, diameter, color uniformity, etc.) and internal features (such as water content, pest and disease erosion, fiber structure, etc.) of the stem. The data obtained by the image processing unit is presented in the form of intuitive images and data reports on the display 7, making it convenient for the operator to view in real time.

[0066] In some embodiments, the device body 8 is also provided with a network interface or a storage interface for transmitting data to a cloud server or an external device. In this way, not only can the data be shared in real time and remotely monitored, but also the long-term storage, subsequent analysis and tracing of the data can be facilitated, and more reliable basis for breeding decisions can be provided.

[0067] Although the embodiments of the present application have been shown and described above, it should be understood that the above-described embodiments are exemplary and are not to be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above-described embodiments within the scope of the present application.
