Fig. Figure 3 is a top view of the present utility model. Fig. Figure 4 is a schematic structural view of embodiment 4 of the present utility model. Detailed embodiments of the utility model

[0018] The embodiments of this utility model are described in more detail below with reference to the attached drawings. Design 1

[0019] A device for capturing images of individual tobacco plants, comprising a support rod 1, the height of which is adjustable; a ring element 2 is arranged on the support rod 1, the ring element 2 is placed around the tobacco plant, a receiving arrangement 3 is arranged on the ring element 2, and the receiving arrangement 3 is slidably arranged on the ring element 2; a curtain arrangement 4 is further arranged on the ring element 2, the curtain arrangement 4 is opposite the receiving arrangement 3, and the curtain arrangement 4 moves with the movement of the receiving arrangement 3. The support rod 1 is a telescopic rod with a height adjustment range of 0.5 m to 3.5 m. The support rod 1 allows for height adjustment. In the present application, the support rod 1 is designed as a telescopic structure, using a conventional tubular plug-in construction.Depending on the practical application, several interlocking tube sections of different heights can be combined. The telescopic adjustment is manual; alternatively, the support rod can also be adjusted using a screw lock, spring, or electric drive. The telescopic design of the support rod is state-of-the-art and is therefore not described in detail here. Aluminum alloy, carbon fiber, and similar materials can be used for the support rod 1. The height adjustment range of the support rod 1 is between 0.5 m and 3.5 m, which is suitable for the growth height of most tobacco plants.

[0020] The ring element 2 has a hinged ring construction and comprises at least two arc sections, wherein one end of adjacent arc sections is rotatably connected via a hinge and another end is detachably fixed via a locking element, and the ring element 2 can be placed laterally around the tobacco plant and attached to its circumference by opening and closing.

[0021] Opening, closing, and enclosing the ring element 2 from the side is achieved via a hinge and a locking mechanism. This overcomes the major disadvantages of the conventional one-piece closed ring element, which must be attached to the tobacco plant from above—namely, difficult installation on tall tobacco plants, the risk of scratches and damage to leaves and stems, and low installation efficiency in the field. Installation can be carried out quickly by a single person without disturbing the natural growth of the tobacco plant. Once closed, a completely enclosed sliding rail is formed, thus fully maintaining the core functions of the original device—360° sliding engagement and synchronous curtain coverage. After unlocking, the element can be folded, reducing its transport volume.This significantly improves the efficiency of the device in fieldwork, portability, and suitability for large-scale monitoring of tobacco fields.

[0022] Furthermore, a tripod 11 is arranged at one end of the support rod 1, the tripod 11 being in contact with the ground and serving to stabilize the support rod 1. The tripod 11 is detachably connected to the support rod 1, but can also be permanently connected. When in use, the tripod 11 is placed on the ground and provides a certain degree of stability.

[0023] Specifically, the ring element 2 is positioned at the end of the support rod 1 furthest from the ground and is detachably connected to the support rod 1. The ring element 2 can be attached to the end of the support rod 1 and can be detachably fastened using a snap fastener, nuts, screws, or similar means. For excessively large tobacco plants, the ring element 2 can be replaced so that the tobacco plant can still be enclosed within the ring element 2. The ring element 2 can be made of either plastic or metal.

[0024] Specifically, a slide rail is arranged on the inner wall of the ring element 2, with the receiving assembly 3 being slidably mounted on the slide rail, thus enabling positional adjustability on the ring element 2. The slide rail is arranged on the inner wall of the ring element 2 and can be designed as a smooth rail. The end of the receiving rod 31 in the receiving assembly 3 is adapted to the smooth rail; for example, a sliding block can be provided at the end, allowing the receiving assembly 3 to slide on the inner side of the ring element 2. Furthermore, the assembly can also be designed as a gear structure or a chain structure. If the slide rail is designed as a gear structure, the inner wall of the ring element 2 has a smooth rail in which a chain-gear structure is arranged. The chain-gear structure forms a closed drive structure within the rail.The end of the receiving rod 31 meshes with the gear structure and is driven by it on the ring element 2 to adjust the position.

[0025] Specifically, the inner diameter of ring element 2 is 80 cm to 100 cm. This corresponds to the outer diameter of most tobacco plants.

[0026] Specifically, the recording arrangement 3 comprises a mounting rod 31 and a camera 32, wherein the mounting rod 31 is slidably connected to the ring element 2, and the camera 32 is detachably connected to the mounting rod 31. One end of the mounting rod 31 is slidably connected to the inner wall of the ring element 2, while the other end serves to attach the camera 32. Furthermore, the mounting rod 31 is angle-adjustable; that is, the end to which the camera 32 is attached is angle-adjustable, and the point where the camera 32 is attached is rotatably connected to the connection point between the mounting rod 31 and the ring element 2. As shown in the drawings, the mounting rod 31 can be configured as both a connecting rod and a mounting end, with the connecting rod being adapted to the sliding rail and rigidly connected to the mounting end.The mounting end is detachably connected to the camera or other recording devices, for example by a snap connection. Design 2

[0027] Specifically, a stepper motor is arranged on the slide rail. The stepper motor is connected to the sliding assembly, which is located within the slide rail. The stepper motor controls the sliding assembly to drive the receiving assembly 3 to slide on the ring element 2. The stepper motor is connected to the sliding assembly, which is enclosed within the slide rail. The rotation of the stepper motor moves the sliding assembly, thereby driving the receiving rod 31 on the sliding assembly. Specifically, the stepper motor can be pre-programmed via a control unit, such as a PLC, to set the rotational speed. For example, the receiving assembly 3 can be moved on the ring element 2 at a speed of 5° every 10 seconds, thus achieving automatic movement of the receiving assembly 3 along the inner wall of the ring element 2.This allows the tobacco plant to be photographed and observed from all angles. Simultaneously, in combination with the telescopic pole, the tobacco plant can be observed from different angles depending on its stage of growth.

[0028] Specifically, the curtain assembly 4 comprises a sliding block 41 and a curtain 42, the curtain being rigidly connected to the sliding block, and the sliding block being compatible with the sliding assembly. The sliding block engages with the sliding assembly on the inner wall of the ring element 2. When the receiving assembly 3 is moved onto the sliding assembly on the inner wall of the ring element 2, the sliding assembly can move the sliding block 41 along with it, ensuring that the curtain assembly 4 always remains positioned relative to the receiving assembly 3 and preventing other interference. The curtain 42 can be made of a lightweight, durable, and wind-resistant material such as polyester fabric. In particular, a black curtain can be used to further emphasize the growth characteristics of the tobacco plant. embodiment 3

[0029] If the receiving assembly 3 is not automatically controlled, i.e., if the receiving assembly 3 and the inner wall of the ring element 2 are designed as a sliding block and smooth sliding rail, the receiving assembly 3 and the curtain assembly 4 can be connected to each other via an arcuate connecting element. When the receiving assembly 3 is moved, the curtain assembly 4 moves along with it, so that the relative position is always maintained.

[0030] When using the device, the support pole 1 is placed next to a single tobacco plant, and the ring element 2 is positioned around the plant. Since the support pole 1 is telescopic, its position can be adjusted according to the height of the tobacco plant. After adjusting the height of the support pole 1, the pickup assembly 3 can be activated to collect the tobacco plant. During pickup, the pickup assembly 3 slides along the ring element, allowing the tobacco plant to be captured from various angles within a 360-degree range. Simultaneously, the support pole 1 can be adjusted according to the growth stage of the tobacco plant. Furthermore, the curtain assembly 4 is positioned opposite the pickup assembly 3, with its movement synchronized with that of the pickup assembly 3.When the recording setup 3 captures the individual tobacco plant, the curtain setup 4 can obscure other tobacco plants and interfering objects, ensuring that recording setup 3 captures images of only the single tobacco plant. This improves the accuracy of subsequent monitoring comparisons and data analyses. Design 4

[0031] Two ring elements 2 can be provided, arranged parallel, concentrically, and coaxially, namely a first ring element 21 and a second ring element 22. The first ring element 21 is arranged on the support rod 1, which is telescopically designed. The receiving arrangement 3 is arranged on the first ring element 21 and is driven by a drive mechanism, such as a stepper motor. The structure of the ring elements and the drive mechanism are identical to those described above. The first ring element 21 can move vertically by means of the telescoping movement of the support rod 1. Furthermore, the second ring element 22 is arranged on the fixing rod 5, which has the same maximum height as the support rod 1. The curtain arrangement 4 is arranged on the inner wall of the second ring element 22, positioned opposite the receiving arrangement 3.The second ring element 22 incorporates a slide rail and a drive device. The connection and drive mechanism of the curtain assembly 4 to the inner wall of the second ring element 22 are identical to those described above. If the slide rail on the inner wall of the second ring element 22 is driven by a stepper motor, the speed, direction of rotation, and other parameters must be set synchronously with the drive of the receiving assembly 3. In this embodiment, the curtain assembly 4 has a fixed height, specifically the maximum height of the support rod 1. When the receiving assembly 3 moves vertically due to the telescoping movement of the support rod 1, the vertical height of the curtain assembly 4 remains unchanged. This allows the receiving area of ​​the receiving assembly 3 to be further cleared of obstructions.
