Description

Technical Field

[0001] The invention relates to the technical field of grassland measurement, and more particularly to a variable-size sample square frame based on a grassland sample plot species identification and recommendation device. Background Art

[0002] Grassland is an important component of the ecosystem and is of great significance to environmental protection, animal husbandry and agricultural production. In grassland management and research, sample site selection is a key step in evaluating grassland quality and ecological function. However, traditional sample site selection methods have problems such as high subjectivity, low efficiency and poor repeatability, which limits the accuracy and reliability of grassland management and research.

[0003] In the process of plant community structure investigation, resource inventory, ecological monitoring, etc., it is often necessary to set up sample plots in the field to investigate the number, frequency, growth characteristics and other factors of biological distribution. Sample plot investigation is a necessary investigation method that can quickly investigate the data of various growth factors of organisms and provide a reliable basis for scientific research and resource investigation. However, most of the existing sample plots adopt a fixed structure, which is inconvenient to carry and cannot meet the sample plot specification requirements in different scenarios.

[0004] Existing grassland sample plot selection tools have some defects. Traditional methods rely on manual experience and subjective judgment. The results are affected by individual differences and subjective factors, resulting in inconsistency and reduced credibility of the results. In addition, existing tools lack the ability to solve and evaluate in real time, and cannot provide immediate feedback and accurate recommendation results. At the same time, some tools have limitations on the selection of grassland sample plots of different sizes and cannot flexibly adapt to different research needs.

[0005] Therefore, it is very necessary to design a variable-size sample box based on grassland sample plot species identification and recommendation device. Summary of the invention

After the assembly is completed, the ball head 18 can smoothly slide from the first spiral groove 16 into the second spiral groove 61.

[0061] Example 4, please refer to Figure 1-16 The fourth embodiment makes the following improvements on the basis of the third embodiment. Specifically, a data acquisition unit is sequentially arranged inside the GPU computing edge box 13 , and the data acquisition unit is used to acquire image data acquired by the camera 14 .

[0062] Equipped with high-resolution camera equipment, using optical lenses with a resolution of 4K or above, combined with wide-angle and autofocus technology, it ensures that delicate image data can be clearly captured even in low-light conditions.

[0063] The camera uses a multi-angle rotation shooting mode to increase image coverage and ensure that data of the sample area is fully captured from multiple perspectives.

[0064] During the image acquisition process, the system automatically adjusts the camera's exposure, contrast, and white balance parameters in real time to ensure consistent image quality under changing lighting conditions and avoid fluctuations in image quality.
