Description

Technical Field

[0001] The present application relates to the technical field of grassland biomass measurement, and more specifically, to a comprehensive and non-destructive measurement device for grassland biomass. Background Art

[0002] Currently, the measurement of aboveground biomass in grasslands relies primarily on ground-based sample surveys and remote sensing technology. Ground-based sample surveys can provide relatively accurate biomass data, but they are labor-intensive and difficult to measure over large areas. Remote sensing technology, on the other hand, utilizes satellite imagery or drone imagery. Drones equipped with multispectral cameras can capture multispectral images of ground vegetation. By processing this image data using specialized algorithms, highly accurate estimates of aboveground biomass in grasslands can be achieved.

[0003] The existing public technology number CN218782201U proposes a comprehensive and non-destructive measurement device for grassland biomass. The device is equipped with a drone control module, a clamping mechanism and a sample frame. The electric telescopic rod is started and pressed against the other side of the connecting rod. The connecting rod is stably clamped by a rubber pad. The limit block has a limiting function to prevent the connecting rod from slipping during flight. The sample frame is flown with the connecting rod to the sky above the grassland. The measurement site is selected and the sample frame is lowered. The CCD camera at the bottom of the drone control module records the grass amount through remote sensing technology to form an image. By driving the sample frame to select different sample locations for detection, the average value is finally calculated to make the obtained data more accurate, and the drone control The module and the sample frame are matched to avoid damage to the grassland. Regarding the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: Although the grassland biomass measurement drone in the comparative literature can achieve non-destructive measurement, the drone needs to land at a certain ground height and allow the sample frame to be laid on the grass. When the CCD camera takes an image, the organisms on the grass will be bent by the wind generated by the high-speed rotation of the drone fan, resulting in inaccurate measurement work, such as biological growth height data, and when measuring grassland in dark areas, there is no lighting processing, and image acquisition and sampling measurement work cannot be achieved. In view of this, we propose a comprehensive and non-destructive measurement device for grassland biomass. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] The purpose of the present application is to provide a comprehensive non-destructive measurement device for grassland biomass, which solves the problem that although the grassland biomass measurement drone in the comparative literature in the above-mentioned background technology can achieve non-destructive measurement, the drone needs to land at a certain ground height and allow the sample frame to be laid on the grass. When the CCD camera takes an image, the organisms on the grass will be bent by the wind generated by the high-speed rotation of the drone fan, resulting in inaccurate measurement, such as the biological growth height data, and when measuring grassland in dark areas, there is no lighting processing and the image acquisition and sampling measurement work cannot be achieved. The invention realizes the use of drone hovering technology and the laying of the grassland measurement area with the sample measurement frame to achieve non-destructive measurement. The lighting can be used for lighting processing to avoid the phenomenon that dark areas cannot be imaged. Four transparent wind shields are set on the sample measurement frame to form a conical three-dimensional structure, so that the strong wind generated by the remote sensing drone will not cause the organisms on the grass circled by the sample measurement frame to bend, thereby ensuring the accuracy of the measurement data and the practicality of the technical effect.
