[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0025] This embodiment provides a deep-buried UAV ground permanent fixed target device, see Figure 1-4 The main structure includes a target tube 1, a cover device 2 for sealing the target tube 1, a target reflection device 3 during use, and a telescopic storage mechanism 4. These parts cooperate with each other to achieve the functions of stable installation, precise positioning and long-term use of the target device.

[0026] The target reflector 3 is a crucial component of the target detector. Low-altitude drones can identify the target's location through the reflective cloth, which is recognizable by drones, thereby accurately obtaining the target's precise coordinates on the drone image. The entire device features a simple structure, easy installation, low cost, high accuracy, and a one-time measurement for permanent use, making it particularly useful for specific, fixed monitoring locations.

[0027] In a specific embodiment, see Figure 5-6The upper cover device 2 includes a top cover 201 and a top cover fixing device 202. The top cover fixing device 202 is a circular device with a household-shaped groove. It is fixedly installed on the top of the target tube 1 and can be fitted with the target tube 1. The device can be fixed to the ground by nails, playing a ring-shaped role in fixing the target tube 1. The top cover 201 and the top cover fixing device 202 are connected by a threaded structure, and the threaded knob is formed to seal the top opening of the target tube 1, forming a watertight target tube 1 space, effectively preventing water erosion and protecting the internal structure. Preferably, the top cover 201 and the top cover fixing device 202 are both designed to be circular.

[0028] In a specific embodiment, the target tube 1 is a device for storing permanently fixed target devices, and has a shape of a pointed bottom and a round top, which is convenient for insertion into the soil during installation.

[0029] In a specific embodiment, see Figure 3-4 The target reflection device 3 includes a target, the structure of the target consists of a rod body 5, an expandable target surface 6, and a driving component 7 for controlling the expansion and storage of the target surface 6; the target surface 6 is made of reflective cloth and is circular when expanded; a fixing plate 8 is sleeved on the middle part of the rod body 5, and the fixing plate 8 is fixed to the inner wall of the target tube 1. A through hole is provided on the fixing plate 8 to match the rod body 5, and the rod body 5 can move axially along the target tube 1 through the through hole; the bottom end of the rod body 5 is connected to a telescopic storage mechanism 4, and the other end of the telescopic storage mechanism 4 is fixedly connected to the target tube 1 inner bottom, the target surface 6 is arranged at the top end of the rod body 5; the driving assembly 7 is arranged on the rod body 5. When in use, the top cover 201 is opened, the target is pulled outward, the driving assembly 7 is operated to unfold the target surface 6, and the position of the target is fixed by the cooperation of the telescopic storage mechanism 4 and the driving assembly 7. When storing, the driving assembly 7 is operated, and the target rebounds inward into the target tube 1 under the action of the spring to maintain an upright state, and the position of the target in the target tube 1 is fixed by the cooperation of the telescopic storage mechanism 4, the target surface 6 and the fixing plate 8.

[0030] In a further preferred embodiment, see Figure 3-4 The telescopic storage mechanism 4 includes a spring device 401, one end of the spring is fixedly connected to the bottom end of the rod body 5, and the other end is connected to the inner wall of the target tube 1.

[0031] In a further preferred embodiment, the target surface 6 structure includes an umbrella-shaped frame and a reflective cloth, the reflective cloth being overlaid on the umbrella-shaped frame, which is hinged at its center to the top of the rod 5. When the umbrella-shaped frame is unfolded, its entire top is rounded, and the rod 5 connected thereto has a tendency to move downward under the tension of the spring device 401. At this time, the umbrella-shaped frame cooperates with the top opening of the target tube 1, thereby achieving a relatively stable target position. When the umbrella-shaped frame is stored in the target tube 1, similarly, the rod 5 has a tendency to move downward under the action of the spring device 401. At this time, the end of the umbrella-shaped frame in the stored state abuts against the fixed plate 8, which acts as a limiter against the inner wall of the target tube 1, thereby achieving a relatively stable target position.

[0032] In a further preferred embodiment, see Figure 3-4 The drive assembly 7 controls the expansion and retraction of the umbrella-shaped frame. It comprises an external thread 701 on the rod body 5, an inner cylinder 702 threadedly connected to the rod body 5, an outer cylinder 703 sleeved and rotatably connected to the inner cylinder 702, and a hinged rod 704 hinged at one end to the outer cylinder 703 and at the other end to the umbrella-shaped frame. The inner cylinder 702 is axially longer than the outer cylinder 703, facilitating manual rotation of the inner cylinder 702 and movement of the outer cylinder 703 along the axis of the rod body 5. In the retracted state, the umbrella-shaped frame is retracted inward within the target tube 1. To deploy, the inner cylinder 702 is rotated, causing the outer cylinder 703 to move upward along the axis of the rod body 5, thereby expanding the umbrella-shaped frame via the hinged rod 704. To retract, the inner cylinder 702 is rotated in the opposite direction, causing the outer cylinder 703 to move downward along the axis of the rod body 5, thereby retracting the umbrella-shaped frame inward via the hinged rod 704.

[0033] Specific usage and working principle:

[0034] Step 1: Choose a flat and stable surface, remove weeds and rocks, and ensure the surface is clean and free of foreign matter.

[0035] Step 2: Use a drilling machine to drill holes at the selected location. The hole depth should be adjusted according to actual needs and should generally be between 50-100cm.

[0036] Step 3: Partially insert the deep-buried target tube 1 of the deep-buried UAV ground permanent fixed target device into the drilled hole, ensuring that the tip of the target tube 1 is completely inserted into the soil.

[0037] Step 4: Use a screwdriver to fix the top cover fixing device 202 on the ground, ensuring that the top cover 201 and the top cover fixing device 202 fit tightly together to form a watertight sealed space.

[0038] Step 5: Conduct a flight test of the drone, open the top cover 201, pull out the target reflector 3 upwards, and rotate the inner cylinder 702 of the drive assembly 7 to control the umbrella-shaped frame to unfold upwards, ensuring that the target reflector cloth is fully unfolded to form a circle so that the drone can accurately identify it.

[0039] Step 6: Under the pulling force of the spring device 401 , the umbrella-shaped frame abuts against the top of the target tube 1 , fixing the target on the top of the target tube 1 to maintain the stability of the target.

[0040] Step 7: The low-altitude drone can identify the position of the target through the reflective cloth. Once the target position is identified, the coordinates of the top corner of the L-shaped target can be measured on the ground through a coordinate measuring device. By identifying the target and puncturing the top corner of the L-shaped target, the precise coordinates of the target point on the drone image can be accurately obtained.

[0041] Step 8: Perform subsequent data analysis and processing based on the acquired coordinate data. The above are the specific operation steps of this embodiment. In this way, the monitoring accuracy of the drone can be effectively improved, errors can be reduced, and the impact on ground objects and biological activities can be avoided, thereby protecting the environment.

[0042] The deep-buried UAV ground permanent fixed target device of this embodiment has the following beneficial effects:

[0043] Precise Positioning: The design of the target reflector 3 enables the drone to accurately identify the target position through the reflective cloth, thereby obtaining precise ground coordinates. This design is suitable for low-altitude drone operations and ensures target identification and measurement accuracy.

[0045] Easy to install and operate: The device has a simple structure and is easy to install. Users only need to perform a few operations to complete the deployment and storage of the target, which reduces the complexity of installation and use and improves work efficiency.

[0046] Environmental protection: The deep-buried design of this device reduces interference with ground objects and biological activities, protects the environment, and is especially suitable for long-term fixed monitoring points without affecting the ground ecology and human activities.

[0047] Low cost and high precision: Compared with traditional monitoring equipment, the target device has a lower manufacturing cost and high-precision measurement capability, which can meet long-term measurement needs without frequent replacement or maintenance.

[0048] Waterproof design: The waterproof structure of the top cover 201 and the top cover fixing device 202 effectively prevents rainwater or other liquids from entering the target tube 1, ensuring the long-term stability of the device and the protection of the internal structure.

[0049] Flexible storage: The target surface 6 with an umbrella-shaped skeleton design can be quickly unfolded and stored. When not in use, the target can be easily stored in the target tube 1 through the drive component 7 and the spring device 401, reducing damage to the target from external factors and avoiding wear and tear caused by long-term exposure.

[0050] Adaptable to various environments: As the device is waterproof, dustproof and resistant to external damage, it is suitable for long-term use in a variety of outdoor environments, including complex climatic and geographical conditions.
