Device and method for hyperspectral remote sensing extraction of mikania micrantha based on unmanned aerial vehicle platform

Abstract

The invention relates to the field of unmanned aerial vehicle monitoring and discloses a device and a method for hyperspectral remote sensing extraction of mikania micrantha based on an unmanned aerial vehicle platform. The method comprises the following steps: S1, carrying a hyperspectral data acquisition module through an unmanned aerial vehicle platform, planning an air route, flying in a mikania micrantha concentrated growing region, to obtain hyperspectral data; S2, carrying out radiation correction processing on the hyperspectral data, including noise removal and reflectance inversion processing; S3, carrying out geometric correction processing on the hyperspectral data to improve interpretation precision of the data; S4, extracting spectral features and selecting texture features based on a hyperspectral data image of the step S3, classifying the images by combining the spectral features and the texture features, and extracting a coverage area of mikania micrantha; S5: making amikania micrantha coverage map according to the coverage range. The hyperspectral extraction technology of mikania micrantha provided by the invention enables mikania micrantha to be accurately delineated and positioned, and realizes automatic and intelligent extraction.

Description

technical field [0001] The invention belongs to the UAV monitoring technology, in particular to a UAV-based hyperspectral remote sensing extraction technology of Mikania micrantha. Background technique [0002] Mikania micrantha is a more harmful invasive alien species that entangles and climbs other woody plants, hindering their growth and development. It is a perennial herb of the Asteraceae family, native to South and Central America, and has now spread widely to tropical Asia, such as India, Malaysia, Thailand, Indonesia, Nepal, the Philippines, as well as Papua New Guinea, Solomons, Christmas Island in the Indian Ocean, and the Pacific Ocean Some of the islands on the island include Fiji, Western Samoa, and North Queensland in Australia. It has become one of the most harmful weeds in tropical and subtropical regions of the world today. This species has been listed as one of the 100 most harmful invasive alien species in the world. It is also included in the first batc...
