Mobile-based integrated early warning and detection method and device for pine wood nematode disease

Abstract

The invention provides a mobile terminal-based integrated early warning and detection method and device for pine wood nematode disease. The mobile terminal-based integrated early warning and detection method for pine wood nematode includes: extracting features from first image information, and then performing feature extraction on first image information. When the image information includes the characteristics of discolored wood, the characteristics of the host species of B. xylophilus, and the characteristics of the B. xylophilus vector, obtain the second image information corresponding to the target stand; perform feature extraction on the second image information, where the second image information includes In the case of pine wood nematode characteristics, the damage stage detection information of the target diseased trees in the target stand is generated based on the first image information; wherein the first image information includes biological information of at least a part of the area in the target stand, and the second image information includes The wood segment information of the target discolored wood in the target stand. The mobile terminal-based integrated early warning and detection method for pine wood nematode disease of the present invention can realize rapid, efficient and accurate pre-disaster early warning and post-disaster detection of pine wood nematode.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a mobile terminal-based integrated early warning and detection method and device for pine wood nematode disease. Background technique [0002] The pine wood nematode is a devastating forest disease caused by the major quarantine pest, the pine wood nematode, which has caused great harm to the pine forest resources and the natural ecological environment. [0003] At present, morphological methods and molecular detection techniques are often used for the detection and identification of pine wood nematode disease. To carry out such identification work, it is necessary to sample discolored wood. Conditions such as topography and labor are difficult to achieve, and the huge number of nematode samples will also pose considerable challenges to the development of morphological and molecular detection. SUMMARY OF THE INVENTION [0004] The invention provides an integrated ear...
