Description

Technical Field

[0001] This utility model relates to the field of smart agricultural equipment technology, specifically to a camera adjustment mechanism based on an agricultural smart terminal vehicle. Background Technology

[0002] With the deep integration of agricultural modernization and intelligentization, intelligent terminal vehicles, as the core execution unit of smart agriculture systems, have been widely used in scenarios such as farmland data collection, crop harvesting, and environmental monitoring. Taking a smart agriculture platform as an example, intelligent terminal vehicles, equipped with cameras, ultrasonic radar, robotic arms, and other devices, achieve real-time perception and automated operation of crop growth status. Among them, the camera, as the core component of visual perception, undertakes key functions such as crop identification (e.g., 12 types of crops such as peppers and eggplants), landmark positioning (e.g., achieving a recognition accuracy rate of over 99.5% through the YOLO V8 model), and path planning assistance.

[0003] However, existing camera mechanisms on smart terminal vehicles suffer from significant technical bottlenecks in terms of viewing angle adjustment and environmental adaptability. Most cameras on these vehicles are fixedly mounted or have a single-axis adjustment design, failing to meet the multi-dimensional viewing requirements of agricultural scenarios. When crop heights vary significantly, fixed-view cameras struggle to simultaneously and clearly capture images of crops at different heights. For example, when the vehicle takes close-up shots of low-growing crops, fixed cameras are prone to image distortion due to excessive downward angles; while when detecting tall crops, limited upward angles prevent the complete capture of canopy details. Furthermore, in complex farmland environments (such as row planting or greenhouse partitions), fixed-view cameras are easily obstructed by plant cover, unable to quickly switch to shooting from the side or shaded side of the crop. This leads to misjudgments by computer vision models due to missing features (e.g., misidentifying immature crops as mature), hindering the improvement of the operational efficiency and accuracy of smart agriculture systems.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, the purpose of this utility model is to propose a camera adjustment mechanism based on an agricultural intelligent terminal vehicle, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A camera adjustment mechanism based on an agricultural intelligent terminal vehicle includes: a camera assembly, and a vertical plate that is movably inserted into the vehicle body. The top of the vertical plate has an adjustment groove, and a support rod is slidably disposed in the adjustment groove. An adjustment rod is fixedly connected to the end of the support rod, and the adjustment rod is movably connected to an assembly plate through a rotating shaft. The camera assembly is snapped onto the assembly plate.

[0008] An adjusting crank is fixedly connected to the bottom end of the upright plate.

[0009] Furthermore, the adjusting groove is provided with a limiting slide rail, and the bottom of the support rod is provided with a slider that cooperates with the limiting slide rail.

[0010] Furthermore, a locking mechanism is provided at the pivot point between the adjusting rod and the mounting plate, the locking mechanism including a locking bolt or a damper.

[0011] Furthermore, the support rod and adjusting rod are made of hollow aluminum alloy and filled with shock-absorbing rubber.

[0012] Furthermore, the camera assembly is connected to the mounting plate via a flexible snap-fit.

[0013] Furthermore, the bottom end of the upright plate is provided with a guide sleeve, and the upright plate is movably connected to the vehicle body through the guide sleeve.

[0014] The beneficial effects of this utility model are:

[0015] This invention allows for the adjustment of the overall height of the camera assembly by rotating the upright plate using an adjustable crank. The sliding of the support rod within the adjustment groove changes its connection to the upright plate, thereby adjusting the horizontal position of the camera assembly via the adjusting rod and mounting plate. The adjusting rod and mounting plate are connected by a pivot and equipped with a locking mechanism, enabling adjustment of the camera assembly's angle in the vertical plane. Through the synergistic action of these multiple components, the camera assembly can be adjusted in multiple dimensions, including height, horizontal position, and angle. This meets the multi-dimensional perspective shooting needs of crops at different heights and positions in agricultural scenarios, avoiding image distortion and feature loss caused by fixed perspectives. In complex farmland environments, the camera's height, horizontal position, and angle can be flexibly adjusted according to actual shooting needs, quickly switching to suitable shooting positions such as the side or backlit side of the crop, effectively avoiding plant obstruction. This ensures that the computer vision model can acquire complete and accurate crop feature information, reducing misjudgments and improving the operational efficiency and accuracy of the smart agriculture system. It effectively solves the technical bottlenecks of existing intelligent terminal vehicle camera mechanisms, demonstrating significant technological advancement and practical application value.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a camera adjustment mechanism based on an agricultural intelligent terminal vehicle is provided.

[0026] like Figures 1-3As shown, a camera adjustment mechanism based on an agricultural intelligent terminal vehicle includes: a camera assembly 1, and a vertical plate 2 that is movably inserted into the vehicle body. The top of the vertical plate 2 has an adjustment groove 3, and a support rod 4 is slidably provided in the adjustment groove 3. An adjustment rod 5 is fixedly connected to the end of the support rod 4. The adjustment rod 5 is movably connected to an assembly plate 6 through a rotating shaft. The camera assembly 1 is snapped onto the assembly plate 6. An adjustment crank 7 is fixedly connected to the bottom of the vertical plate 2.

[0027] The adjusting groove 3 is equipped with a limiting slide rail, and the bottom of the support rod 4 is equipped with a slider that cooperates with the limiting slide rail. The adjusting rod 5 and the rotating shaft of the mounting plate 6 are equipped with a locking mechanism, which includes a locking bolt or a damper. The support rod 4 and the adjusting rod 5 are made of hollow aluminum alloy and are filled with shock-absorbing rubber.

[0028] This technical solution allows for the adjustment of the overall height of the camera assembly 1 by rotating the upright plate 2 via the crank 7. The sliding of the support rod 4 within the adjustment groove 3 changes its position connected to the upright plate, thereby adjusting the horizontal position of the camera assembly via the adjusting rod 5 and the mounting plate 6. The adjusting rod 5 and the mounting plate 6 are connected by a pivot and equipped with a locking mechanism, enabling adjustment of the camera assembly's angle in the vertical plane. Through the coordinated action of these multiple components, the camera assembly 1 can be adjusted in multiple dimensions, including height, horizontal position, and angle, meeting the multi-dimensional perspective shooting needs of crops at different heights and positions in agricultural scenarios, and avoiding image distortion and feature loss problems caused by a fixed perspective.

[0029] Meanwhile, the support rod 4 and the adjusting rod 5 are made of hollow aluminum alloy, which is lightweight and high-strength, ensuring the structural stability of the adjustment. The internal filling of the rods with shock-absorbing rubber can effectively reduce the vibration of the camera assembly 1 caused by road bumps and other factors during the operation of the intelligent terminal vehicle in the farmland, protect the normal operation of the camera assembly 1, and extend its service life.

[0030] In addition, the camera assembly 1 is connected to the mounting plate 6 via a flexible snap-fit.

[0031] Specifically, the camera assembly 1 is connected to the mounting plate 6 via elastic clips, making installation and disassembly convenient and quick, facilitating maintenance operations such as inspection and replacement of the camera assembly 1; the connection structure between the components is simple and reliable, reducing the maintenance cost and difficulty of the equipment.

[0032] In addition, the bottom of the upright plate 2 is provided with a guide sleeve, and the upright plate 2 is movably connected to the vehicle body through the guide sleeve.

[0033] In application, when it is necessary to photograph crops at different heights, the crank 7 is adjusted in conjunction with the guide sleeve to rotate the upright plate 2, thereby raising or lowering the upright plate 2 to match the height of the camera assembly 1 with that of the crops; the horizontal position of the camera assembly 1 is adjusted by sliding the support rod 4 to avoid obstruction by plants in front; and the tilt angle is adjusted by rotating the assembly plate 6 to ensure clear and distortion-free image acquisition.

[0034] Furthermore, the aforementioned adjusting crank 7 can be replaced with an electric actuator, which is connected to the trolley control system via a wire. The operator can send commands via an onboard terminal or remote control software, causing the electric actuator to automatically raise and lower the vertical plate 2, achieving precise electric adjustment of the camera height.

[0035] In summary, the following effects can be achieved by using the above-mentioned technical solution of this utility model: by adjusting the crank 7 to drive the upright plate 2 to rotate, the overall height of the camera assembly 1 can be adjusted; the sliding of the support rod 4 in the adjustment groove 3 can change the position of the support rod 4 connected to the upright plate, and then the horizontal position of the camera assembly can be adjusted by adjusting the adjustment rod 5 and the mounting plate 6; the adjustment rod 5 and the mounting plate 6 are connected by a rotating shaft and are provided with a locking mechanism, which can realize the adjustment of the angle of the camera assembly in the vertical plane. Through the synergistic effect of the aforementioned components, camera assembly 1 can be adjusted in multiple dimensions such as height, horizontal position, and angle to meet the multi-dimensional perspective shooting needs of crops at different heights and positions in agricultural scenarios. This avoids image distortion and feature loss caused by fixed perspectives. In complex farmland environments, it can flexibly adjust the height, horizontal position, and angle of the camera according to actual shooting needs, quickly switching to suitable shooting positions such as the side of the crop or the backlit side, effectively avoiding plant occlusion, ensuring that the computer vision model can obtain complete and accurate crop feature information, reducing the occurrence of misjudgments, improving the operational efficiency and accuracy of the smart agriculture system, and effectively solving the technical bottlenecks of existing intelligent terminal vehicle camera mechanisms. It has significant technological progress and practical application value.
