According to the technical scheme, the
sky-ground
integrated monitoring method comprises the steps that S1, firstly, infected and withered trees are extracted through unmanned aerial vehicle images, plaques of the infected and withered trees are extracted through
satellite images, and on-site marking, positioning and measuring are conducted on the withered trees through ground investigation; s2, respectively acquiring high-spatial-resolution
satellite remote sensing data and unmanned aerial vehicle
remote sensing data as data sources, and jointly forming a
data set of a monitoring area in combination with
ground survey data and
forest resource second-class survey data; s3, establishing samples of the epidemic trees according to the data, wherein the samples comprise spectral features, texture features and geometric features of the
pine wood nematode disease withered and dead trees; and S4, according to the sample and
satellite remote sensing, confirming the infected, withered and
dead tree plaques, comprehensively applying an
image enhancement and image classification method, performing
verification, and establishing
spatial distribution information and position information of the
pine wood nematode disease withered and dead trees. The method has the advantages of high epidemic area screening efficiency, capability of realizing large-area efficient monitoring, convenience in acquisition of remote
sensing data of the unmanned aerial vehicle, high recognition precision and guarantee for precision
verification.
