Method for monitoring growing state of forest trees based on unmanned aerial vehicle

Abstract

The invention discloses a method for monitoring the growing state of forest trees based on an unmanned aerial vehicle. The method for monitoring the growing state of the forest trees is realized through the growing height of forest trees. The major method comprises that the unmanned aerial vehicle flies at a specific height, fixed-point measurement and photographing are carried out through a distance measuring instrument and an imaging device which are carried by the unmanned aerial vehicle, and analysis is carried out through a computer so as to acquire the growing state of the forest trees. The method disclosed by the invention combines an unmanned aerial vehicle remote sensing system and modern forestry detection technologies in allusion to large-scale integration forest farms, and farmers are not required to go to the field to observe growing conditions of the forest trees, thereby saving a lot of labor cost and time. Meanwhile, image data recorded by a computer facilitates people to check at any time and carry out before-and-after comparison, thereby analyzing the actual growing conditions of the forest trees more accurately, and being convenient for carrying out uniform planning and management for large-scale forest farms.

Description

technical field [0001] The invention relates to the field of automatic forestry monitoring equipment, in particular to a method for monitoring the growth state of trees based on an unmanned aerial vehicle. Background technique [0002] Modern forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forest trees to play a protective role; forestry in the human and biosphere, through advanced science and technology and management It is a basic industry and social public welfare undertaking that is engaged in the cultivation, protection and utilization of forest resources, making full use of the multiple benefits of forests, sustainable management of forest resources, and promoting the coordinated development of population, economy, society, environment and resources.

Problems solved by technology

[0004] Along with the development of forestry, modern forestry all adopts the large-scale integrated multi-species cultivation method to cultivate forest trees, planting any large quantities of multiple trees in an area, but planting a single tree in the same area; at the same time for It is convenient for modern urban greening construction. The trees planted are all fast-growing types, and larger plants can be obtained in a short period of time. For such plants, they need to reach a certain height to meet the needs of urban greening. Therefore, real-time monitoring is required for the growth of trees The traditional monitoring of the growth status of trees is only judged by measuring the diameter of the trees and observing with the naked eye, but for modern large-scale forest production, manual measurement or visual judgment requires staff to enter the forest area for on-the-spot measurement and observation. The area itself is relatively large, and a single measurement and inspection requires a lot of manpower and material resources, which is not conducive to the expanded production of modern forestry
