Mountain vegetation vertical zone investigation monitoring method based on UAV

Abstract

The present invention provides a mountain vegetation vertical zone investigation monitoring method based on a UAV. The method comprises the steps of (S1) determining an investigation time, an investigation mode and investigation precision, (S2) planning a route and carrying out automatic monitoring according to a preset route if the investigation mode is a programmed control operation mode, and manually controlling an aircraft to carrying out image capturing and obtaining monitoring data if the investigation mode is a radio remote control operation mode, (S3) carrying out space correcting processing on each image in the monitoring data, realizing the space connection of images, carrying out visual interpretation or computer automatic classification by using the spectrum and texture structure differences of different vegetation zones in a remote sensing image, identifying a vegetation vertical zone boundary, and completing the statistical measurement analysis of a vegetation vertical zone structure and result output through a geographic information system. According to the mountain vegetation vertical zone investigation monitoring method, time and labor are saved, climbing a mountain to carry out sampling positioning by investigation and monitoring personnel is not needed, an investigation result is processed by using the image analysis technology, the vertical vegetation zone identification precision is high, and the positioning is more accurate.

Description

technical field [0001] The invention belongs to the field of monitoring the type and structure of mountainous vegetation, and more specifically relates to a method for surveying and monitoring the vertical zone of mountainous vegetation based on an unmanned aerial vehicle. Background technique [0002] The vertical belt of mountain vegetation refers to the vertical differentiation of mountain vegetation types showing a certain order and arrangement structure with the increase of altitude. The vertical zone of mountain vegetation is not only the basic feature of mountain environment structure, but also one of the classic paradigms of geoscience research. It is still an important content of mountain environment monitoring and scientific research. [0003] At present, there are mainly two ways to obtain information on the vertical zone of mountain vegetation: manual field survey and satellite remote sensing monitoring. Among them, the traditional method of obtaining informatio...
