Early judgment method and device for nematode disease of pine

The invention provides a pine nematode early judgment method and device, and belongs to the technical field of image processing, and the method comprises the steps: obtaining monitoring images of a target pine forest at a plurality of observation moments; performing feature point extraction on each monitoring image to obtain homonymy points of each monitoring image; performing coordinate correction on all the monitoring images based on the homonymy points so as to determine reference information of each pine tree and plaque parameters of each plaque; according to the reference information of each pine tree and the plaque parameter of each plaque, generating an evaluation parameter of the plaque on each pine tree; according to the evaluation parameters, the nematode disease early stage of the target pine forest is determined. According to the early judgment method and device for the pine nematode disease, early diagnosis of the pine nematode disease is achieved with high precision by tracking the time sequence
