A device for dynamically acquiring vegetation coverage

Abstract

A vegetation coverage degree dynamic acquisition device consists of a camera, a camera holder, a camera fixed part, an engine compartment, a support (including a support base and a support measuring rod), a notebook computer, an engine compartment connecting line, and an engine compartment fixed component. The camera is arranged on the camera holder and is fixed by the camera fixed part; an lower end of the support measuring rod is connected with the support base, and the upper end of the support measuring rod is connected with the engine compartment fixed component; the engine compartment is arranged above the engine compartment fixed component, and is connected with the camera through the engine compartment connecting line; and the notebook computer is connected with the camera through a camera connecting line. The invention has the advantages of scientific design, simple structure, easiness for carrying, and efficient cohesion with supporting software. The camera is employed to substitute a digital camera hard for manipulation, and efficient cohesion with supporting software is realized through programs, thereby improving portability and universality of the device, and realizing bulk acquisition of photos of a quadrat and dynamic and real-time acquisition of vegetation coverage degree information during field operation.

Description

technical field [0001] The present invention is a dynamic acquisition device for vegetation coverage used in geography and soil and water conservation monitoring research. It is used in the field to take pictures of the surface coverage of sample plots. Combined with the vegetation coverage dynamic acquisition system (VC-DAS) real-time, dynamic The invention relates to acquiring vegetation coverage information in batches, belonging to the technical field of physical geographic systems. Background technique [0002] As an important indicator of vegetation coverage, vegetation coverage is a basic input variable in simulation models such as rainfall-runoff, soil erosion, and non-point source pollution. Basic data. [0003] Vegetation coverage is usually estimated using simple visual estimation methods, instrument measurement calculation methods, and remote sensing interpretation and analysis methods. Among them, the methods applied to small-scale vegetation coverage measureme...

Problems solved by technology

[0006] The purpose of the present invention is to provide a dynamic acquisition device for vegetation coverage suitable for large batches of quadrat photos in the field. It is different from the digital camera scheme adopted by other devices of the same kind. It is inconvenient to adjust the focus and exposure in real time, unable to see the sample information in real time, and the photo quality is difficult to control. Through the remote control of the camera, the adjustment of the exposure and focus can be realized, and it can be connected to a laptop to see the sample in real time. square information to ensure the quality of the photos taken, which is conducive to ensuring the accuracy of vegetation coverage information extraction
