Description

Technical Field

[0001] The utility model relates to the technical field of remote sensing, and particularly relates to an auxiliary device for laying a reflection target cloth. Background Art

[0002] In the process of collecting remote sensing data, the signals received from the sensor need to accurately reflect the spectral characteristics of different objects on the ground. To ensure the accuracy of the data, a target cloth is required for site calibration. The target cloth provides a known reflectivity, which can be used to correct the data of the sensor and ensure the accuracy of the measurement results. When conducting hyperspectral measurements in the wild, the operator needs to quickly and accurately deploy and recover the target cloth. A well-designed laying auxiliary device can significantly improve work efficiency and reduce the time and labor intensity of on-site operations. Considering that different measurement sites may have different terrains and soil conditions, the laying auxiliary device needs to have good adaptability and flexibility and be able to stably fix the target cloth on different grounds.

[0003] Generally speaking, the auxiliary device for laying the reflection target cloth provides a stable, reliable and easy-to-deploy system for supporting and fixing the reflection target cloth, which is crucial for calibrating aerial or satellite sensors to obtain accurate remote sensing data. The target cloth usually needs to maintain the stability of its position and angle under various environmental conditions to ensure the accuracy and repeatability of the measurement data. Such an auxiliary device can help quickly deploy and recover the target cloth and ensure its stability under the influence of natural conditions such as wind. Content of the Utility Model

[0006] Further, the target cloth is a square light-emitting material cloth, and a central hub is arranged at the center position of the target cloth; a number of telescopic rods are arranged in an array on the central hub;

[0007] Further, the telescopic rods are arranged in an array on the target cloth.

[0017] The auxiliary device for laying a reflective target cloth includes a telescopic rod, a target cloth, a central hub, a coarse focusing screw, a tension regulator, a ground nail, and a support arm;

[0018] A central hub is provided at the center of the target cloth and is connected to the front end of the telescopic rod; a number of telescopic rods are arrayed on the central hub; a tension adjuster is provided at the rear of the telescopic rod and is connected to the four corners of the target cloth, and adjacent telescopic rods are connected by a coarse focusing screw; the front ends of the number of telescopic rods are hinged to each other, and ground nails are provided at the front ends of the telescopic rods.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] In this embodiment, first, an open and flat area is selected to install the device. After determining the center point, the 3 - central hub is installed, which is the core component of the reflective target cloth laying auxiliary device. Subsequently, the 7 - ground nails are driven into the ground with a hammer at the predetermined positions to ensure the stability of the 3 - central hub.

[0022] Multiple 1 - support arms are unfolded from the center of the central hub, and the end of each 1 - support arm is equipped with a telescopic 6 - telescopic rod so as to be adjusted to an appropriate length. By rotating the 4 - coarse focusing screw, the 1 - support arm is fixed at an appropriate angle, providing a basic framework for the laying of the 2 - target cloth.

[0023] Then, a piece of reflective 2 - target cloth is spread on the support arms. The cloth must be kept flat, and at this time, the 5 - tension adjuster comes into play. By adjusting the tension at each support point, it is ensured that the target cloth has no wrinkles and is firmly fixed on the support arms.

[0024] When the laying of the 2 - target cloth is completed, various measuring tools are used to perform the final position calibration on the laid target. If necessary, the telescopic rod and the coarse focusing screw will be finely adjusted until all the marks are exactly the same as those expected.

[0025] After all the position data are recorded and verified to be correct, the device can be removed. First, loosen the 5 - tension adjuster, then gradually retract the 2 - target cloth, fold the 1 - support arms one by one, and finally pull out from the ground.

[0026] Embodiment 2

[0027] In this embodiment, generally, 1 - the support arm is usually made of a lightweight and high - strength material, such as carbon fiber, which ensures both strength and portability. 2 - The target cloth is made of a synthetic material with strong weather resistance, such as nylon, and usually has a reflective coating or is covered with reflective material on its surface to improve its visibility. 3 - The central hub is made of aluminum alloy and requires sufficient strength to support the connected support arms. 4 - The coarse focusing screw is made of metal and is composed of stainless steel to ensure durability and precise adjustment. 5 - The tension adjuster, made of stainless steel, needs to be able to withstand high tension without deformation. 6 - The telescopic rod: similar to the support arm, is made of carbon fiber to be lightweight and stable when adjusting the length. 7 - The ground nail is generally made of metal steel to ensure that it can be firmly fixed on various grounds.

[0028] The usage process of the utility model is as follows:

[0029] Select a suitable site for surveying work and determine the center point of the reflective target cloth. Place the central hub at the predetermined center point, ensuring it is horizontal and stable. Connect the support arm to the central hub and unfold it outward so that it points in the direction where the target cloth is to be laid. Drive the ground nail at the end position of the support arm to fix the position of the support arm. Adjust the length of the telescopic rod according to the actual situation on the ground and the size of the target cloth to adapt to the laying area. Use the coarse focusing screw to make a rough height and angle adjustment of the support arm so that the target cloth can accurately cover the target area. Lay the target cloth and use the tension adjuster to carefully adjust the tension of the target cloth to ensure it is flat and wrinkle - free. Check whether all connection points are firm to ensure that the target cloth is laid correctly and remains stable throughout the measurement process. Use the measuring instrument to align with the marks or reflection points on the target cloth for precise measurement. After the surveying is completed, loosen the tension adjuster, roll up the target cloth, retract the telescopic rod, and remove the ground nail and the support arm, then evacuate the equipment;

[0030] In summary, the present utility model discloses an auxiliary device for laying a reflective target cloth. By stably and correctly deploying the reflective target cloth, the device ensures that the remotely sensed data collected is highly accurate and reliable. This is very important for both scientific research and commercial applications, especially in precise environmental monitoring and resource management.
