Description

Technical Field

[0001] This invention belongs to the field of spectral imaging, specifically a split-type rotating structure plant spectral imaging system. Background Technology

[0002] Sunlight-induced chlorophyll fluorescence (SIF) is a method that measures the intensity of chlorophyll fluorescence in plants under natural sunlight conditions using remote sensing spectroscopy. It can characterize the actual photosynthetic level of plants and thus be used to assess crop growth and vegetation physiological activities. High-precision ground-based spectral measurements are crucial for data validation and the establishment of inversion models.

[0003] Traditional ground-based spectral measurements typically employ handheld spectrometers or fixed stands, but these methods suffer from limitations such as insufficient handheld stability and the difficulty in flexibly adjusting fixed stands. Laboratory-grade equipment, on the other hand, uses specialized equipment stands that are stably mounted in a laboratory to perform optical imaging of samples on a stand-driven sample tray. These equipment stands are often quite large and heavy to stably support the optical camera and move the samples, thus obtaining relatively good spectral imaging data. Due to their size and weight, these equipment stands are generally only installed permanently in fixed laboratories and are difficult to transport to various fields to collect spectra from growing plants.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 5 As shown:

[0024] Example 1: A split-type rotating structure plant spectral imaging system includes a main frame 1. An upper crossbeam 18 is fixedly installed at the top of the main frame 1, a middle crossbeam 19 is fixedly installed in the middle of the main frame 1, and a lower crossbeam 110 is fixedly installed at the bottom of the main frame 1. Several light sources 15 are installed on the middle crossbeam 19. A camera mounting bracket is fixedly installed on one side of the upper crossbeam 18, and a detection camera 12 is installed on the camera mounting bracket. A sliding plate 16 is provided on the inner bottom of the main frame 1. A detection object placement component 2 is fixedly installed at the middle position of the top of the sliding plate 16, and an electrical control box 10 is fixedly installed on one side of the top of the sliding plate 16. The sliding plate 16 can be directly placed on the tabletop of the supporting equipment, and the sliding plate 16 can drive the detection object placement component 2 and the electrical control box 10 to slide into or out of the bottom space of the main frame 1 along the tabletop.

[0025] The electrical control equipment and corresponding control technology inside the electrical control box 10 are all existing technologies and are not the innovations of this utility model, so they will not be described in detail here.

[0026] Preferably, the camera mounting bracket consists of a lifting adjustment component 13 and a detection camera clamping component 3. The lifting adjustment component 13 is fixedly installed on one side of the upper crossbeam 18, the detection camera clamping component 3 is fixedly installed at the output end of the lifting adjustment component 13, and the detection camera 12 is clamped and fixed above the detection camera clamping component 3.

[0027] Preferably, the detection camera clamping assembly 3 includes a fixing block 30 mounted on the upper crossbeam 18. The fixing block 30 is fixedly connected to the top of the detection camera clamping assembly 3. An internal threaded groove 34 is provided at the middle position of one side of the fixing block 30. An adjusting threaded rod 32 is inserted into the internal threaded groove 34. A sliding clamping block 33 is slidably sleeved on the outer side of the adjusting threaded rod 32. A dovetail groove 31 is fixedly installed at the bottom of the detection camera 12. The fixing block 30, the sliding clamping block 33, and the dovetail groove 31 are mutually adapted to each other.

[0028] Preferably, the lifting adjustment component 13 has a conventional screw and slide rail structure or an electric push rod.

[0029] Preferably, the light source 15 can be a halogen tungsten lamp, a deuterium lamp, an LED lamp, or other lamps.

[0030] Preferably, the detection camera 12 can be a surface imaging spectral camera, a line scanning spectral camera, a single-point spectrometer, a Raman spectrometer, or other optical spectral cameras.

[0031] Preferably, protective blocks are fixedly installed at the corners on the outer side of the main frame 1. The protective blocks can be made of plastic, rubber, or foam material. The protective blocks can protect the four corners of the device. The main frame 1 is a cuboid "exoskeleton" frame structure, which is compact and sturdy. The hard frame can protect various equipment components installed inside the frame. It is suitable for packing, transportation, and moving. It protects the equipment inside the frame, such as light sources, optical fibers, cables, electrical equipment, and light-diffusing lenses, from collision damage.

[0032] As can be seen from the above, during imaging, the detection camera 12 is first placed above the fixing block 30. After placement, the adjusting screw rod 32 is rotated to move the sliding clamping block 33. The detection camera 12 is clamped and fixed by the cooperation of the sliding clamping block 33 and the fixing block 30. After the detection camera 12 is fixed, the imaging lens is extended to the inside of the main frame 1. The light source is turned on so that the light source 15 illuminates the detection area of ​​the detection camera 12. The sample is placed in the sample placement tray 22. The sliding plate 16 carrying the detection object placement component 2 and the sample placement tray 22 is slid into the lower space of the main frame 1 along the table. Then, when the detection camera 12 is imaging, the lifting adjustment component 13 is used to raise and lower the detection camera 12. The clarity of the sample imaging is adjusted by raising and lowering. After the camera height is fixed, the detection camera 12 is used for spectral imaging. After use, the detection camera 12 can be disassembled and stored, making it convenient for users to carry the device when going out or when it needs to be moved.

[0033] Example 2: This example is basically the same as the previous example, except that the detection object placement component 2 includes a sample placement tray 22 placed inside the main frame 1. A drive motor 21 is fixedly installed at the bottom inner side of the detection object placement component 2. A rotating block 23 is fixedly installed at the output end of the drive motor 21. A second sliding groove 25 is opened on the top inner side of the detection object placement component 2. A slider 26 is fixedly installed on the top outer side of the rotating block 23, and the slider 26 is adapted to the second sliding groove 25. A positioning rod 24 is fixedly installed at the middle position of the top of the rotating block 23, and the sample placement tray 22 is adapted to the positioning rod 24. Magnets 27 are symmetrically fixedly installed on both sides of the top inner side of the rotating block 23, and the magnets 27 are magnetically connected to the sample placement tray 22.

[0034] The positioning rod 24 is used to position the sample placement tray 22 to prevent the sample placement tray 22 from being tilted during placement, which would affect the imaging effect.

[0035] Preferably, the outer side of the lower part of the rotating block 23 is rotatably connected to the inner side of the upper part of the housing 20. The rotating block 23 and the housing 20 can be rotatably connected through the bearing 26. The rotatable connection between the rotating block 23 and the housing 20 can make the rotating block 23 more stable when rotating, reduce the load on the drive motor 21, and improve the overall stability.

[0036] Preferably, the sample placement tray 22 is made of iron, and the sample placement tray 22 is compatible with the magnet 27. The black surface of the sample placement tray 22 used to place the sample can also be printed with lines or grids of any color to mark the different positions of multiple samples. Different areas of the sample tray can also be labeled with numbers or letters.

[0037] Preferably, a plurality of cooling fans 191 are installed on the central crossbeam 19. Multiple cooling fans 191 can be provided, and their main function is to dissipate heat for electronic components such as the light source 15 and the electrical control box 101. The cooling fans are conventional fans in the prior art, and different sizes of cooling fans and different installation positions can be selected according to actual needs.

[0038] Preferably, the electrical control box 10 contains a rechargeable battery, which facilitates the use of the equipment when it is out of the house.

[0039] Preferably, the bottom of the main frame 1 is symmetrically provided with first grooves 17 on both sides, and the sliding plate 16 is slidably connected to the first grooves 17. The sliding plate 16, which carries the test object placement assembly 2 and the sample placement tray 22, can slide in and out of the lower space of the main frame 1 along the first grooves 17.

[0040] As can be seen from the above, when using the device, first turn on the light source 15 so that the light source 15 illuminates the detection area of ​​the detection camera 12. Pull the sliding plate 16 so that the sliding plate 16 is pulled out from the inside of the main frame 1. After being pulled out, pick up the sample placement tray 22 and place it on the rotating block 23. Then, use the magnet 27 to attract and fix the sample placement tray 22. After fixing, place the plant to be imaged on the sample placement tray 22. Then push the sliding plate 16 to move the detection object placement component 2 into the inside of the main frame 1. After moving to the preset imaging position, use the electrical control box 10 to start the drive motor 21. Use the drive motor 21 to drive the rotating block 23 to rotate. Then use the rotating block 23 to drive the sample placement tray 22 to rotate. Use the detection camera 12 to image the plant sample on the sample placement tray 22.

[0041] Since the main frame 1 and the object placement component 2 are separate, the two parts can be disassembled and separated. Therefore, when needed, the detection devices such as the light source 15 and the detection camera 12 can be directly taken to the conventional conveyor belt with the main frame 1 for use without installing the object placement component 2 and the sliding plate 16.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
