Bursaphelenchus xylophilus disease integrated early warning and detection method and device based on mobile terminal

Abstract

The invention provides a pine wood nematode disease integrated early warning and detection method and device based on a mobile terminal, and the method comprises the steps: carrying out the feature extraction of first image information, under the condition that the first image information comprises color-changing wood features, pine wood nematode host tree species features and pine wood nematode medium features, second image information corresponding to the target forest stand is obtained; feature extraction is carried out on the second image information, and under the condition that the second image information comprises pine wood nematode features, damaged stage detection information of target epidemic trees in the target forest stand is generated based on the first image information; wherein the first image information comprises biological information of at least partial area in the target forest stand, and the second image information comprises wood segment information of the target color-changing wood in the target forest stand. According to the pine wood nematode disease integrated early warning and detection method based on the mobile terminal, fast, efficient and accurate pre-disaster early warning and post-disaster detection of the pine wood nematode disease can be achieved.

Description

technical field [0001] The invention relates to the field of image recognition technology, in particular to a method and device for integrated early warning and detection of pine wood nematode disease based on a mobile terminal. Background technique [0002] Pine xylophilus disease is a devastating forest disease caused by a major quarantine pest, pine xylophilus, which has caused great harm to pine forest resources and the natural ecological environment. [0003] At present, morphological methods and molecular detection techniques are often used to detect and identify pine wood nematodes. To carry out such identification work, it is necessary to sample discolored trees. There are many discolored trees in the forest stand, and the causes of discoloration are different. Conditions such as terrain and labor are difficult to achieve, and a huge number of nematode samples will also pose considerable challenges to the development of morphological and molecular detection.
