Aerial monitoring and identification method and device for migrating insects

Abstract

The invention discloses an aerial monitoring and identification method and device for migrating insects. The method comprises the following steps: firstly, building an insect characteristic parameter database, and then building an insect species image database; on the basis of the databases, determining an insect type to be observed, and selecting a proper observation opportunity and a proper location; determining an observation height according to the insect type; adopting a captive balloon or an unmanned plane to fly to a migrating height, and shooting a video image at the height; monitoring high-altitude meteorological environmental data through a carried sensor; wirelessly transmitting the video image and the environmental data to the ground in real time, and further adjusting an observation position and an observation view angle at the software end; extracting target morphological characteristic parameters from the image through an image processing technology, and comparing the insect image database to identify a possibly existing migrating insect type; further processing an image of a time sequence, thus acquiring information such as an insect moving parameter and an insect swarm density. The method for monitoring the migrating insects also has actual value in the aspects of insect situation prewarning and prevention and reduction of natural disasters to crops.

Description

technical field

[0001] The invention relates to the technical field of insect detection, in particular to a method and device for aerial monitoring and identification of migratory insects. Background technique

[0002] Existing studies have shown that many species of insects migrate in nature. In the field of agricultural production, migratory insects are helpful for crop pollination, but migratory pests destroy crop growth and cause serious economic losses. For this reason, people study the monitoring technology of migratory insects, so as to take control measures in time according to the information of insect situation, and reduce the loss of agricultural production. In order to directly observe and identify the types of insects and study the migratory habits of insects, tethered balloons or kites are usually used to drag aerial insect nets to catch flying insects and obtain measured information such as insect types, numbers, and densities. However, for low-density insec...
