Forestry disease monitoring method and device based on unmanned aerial vehicle

Abstract

The invention discloses a forestry disease monitoring method and device based on an unmanned aerial vehicle. By loading a dual-light camera integrated by a visible light camera and an infrared cameraon the unmanned aerial vehicle, aerial photography monitoring is carried out on a forest in a to-be-monitored area; by analyzing aerial photography data and fully combining with image information of visible light and orthophoto images of normalized difference vegetation indexes, obviously healthy or dead trees are screened out on the basis of the image information of the visible light; then, by combining with NDVI indexes for further judgment, information about the dead trees and ill trees in the to-be-monitored area is thus determined quickly, accurately and efficiently. The current situations that the judgment efficiency is not high and the accuracy is low since identification on forestry diseases only relies on utilization of visible light images or the NDVI indexes are overcome, and therefore the problem that when the forestry diseases and forestry pest disasters happen in the prior art, the ill trees and the dead trees cannot be quickly and accurately found out is solved.

Description

technical field [0001] The invention belongs to the field of monitoring forestry diseases and insect pests, in particular to a method and device for monitoring forestry diseases and pests based on an unmanned aerial vehicle. Background technique [0002] The forest occupies an important position in the national economy. It can only provide the timber and forest by-products needed for national construction and people's life, and it also shoulders the responsibility of releasing oxygen, regulating the climate, conserving water sources, maintaining water and soil, preventing wind and sand, beautifying the environment, and purifying the air. , noise reduction and tourism health care and other missions. At the same time, forests are also an important condition for stable and high yields of agriculture and animal husbandry. [0003] However, forestry diseases have destroyed large forests from time to time. For example, since chestnut blight was introduced to North America around...
