Earth surface vegetation identification method and system based on unmanned aerial vehicle remote sensing technology, and readable storage medium

Abstract

The invention relates to an unmanned aerial vehicle remote sensing technology-based surface vegetation identification method and system, and a readable storage medium. The method comprises the steps of establishing an observation point location, generating an acquisition mode, generating an unmanned aerial vehicle formation according to the acquisition mode, and obtaining formation information; generating scheduling information according to the formation information, and performing position management and control on the unmanned aerial vehicle according to the scheduling information to obtainunmanned aerial vehicle position information; collecting a multi-angle vegetation remote sensing image according to the unmanned aerial vehicle position information, receiving an electromagnetic wavereflection signal, and establishing a vegetation region space through spectral reflectivity characteristics; extracting vegetation space characteristic values, obtaining classification rules, and performing classification processing on the space characteristic values through the classification rules to obtain vegetation information; carrying out geometric decomposition and remote sensing interpretation on the vegetation information to obtain a vegetation type and result information; judging whether a difference value between the result information and preset information is greater than a preset threshold value; and if yes, generating correction information, collecting the position information of the unmanned aerial vehicle through the correction information, and transmitting a correction result to the terminal.

Description

technical field [0001] The invention relates to a surface vegetation identification method, in particular to a surface vegetation identification method, system and readable storage medium based on unmanned aerial vehicle remote sensing technology. Background technique [0002] Vegetation is the general term for the communities of plants that cover the Earth's surface. Environmental factors such as light, temperature and rainfall will affect the growth, reproduction and distribution of plants to a certain extent, thus forming different types of vegetation. Vegetation plays a unique and huge role in the earth's energy conversion, water cycle, atmospheric cycle, etc. It provides food for various organisms to survive and suitable habitats. Among them, human beings obtain from the organic matter produced by vegetation every year About 1.2 billion tons as food. Vegetation also has the functions of improving regional climate, preventing soil erosion, regulating river flow, beauti...

Problems solved by technology

[0003] In order to achieve precise control of vegetation classification and recognition, it is necessary to develop a matching system for control. The system establishes the location of observation points, generates collection methods, and performs UAV formation information to control the location of UAVs. UAV position information collects multi-angle vegetation remote sensing images, and classifies the spatial feature values ​​through classification rules to obtain vegetation information; the UAV position information can be corrected by correcting the information, but in the process of control, how to achieve accurate At the same time of control, it is an urgent problem to be solved to realize the intelligent identification of the distribution of vegetation on the ground by scheduling the UAV.
