A pine wilt tree detection and positioning method based on deep learning

Abstract

The invention discloses a pine wood nematode disease dead tree detection positioning method based on deep learning, and the method comprises the following steps: (1) collecting a sample image, carrying out the preprocessing of the sample image, and carrying out the marking of a pine tree, and obtaining a training sample; (2) training the pine wood nematode disease dead tree training sample by using a deep learning framework and a convolutional neural network to obtain a detection model; (3) enabling the unmanned aerial vehicle to carry out high-altitude fixed-point shooting on the target areaand acquires images and position information; and (4) transmitting the acquired image into a detection model, performing dead tree identification on the acquired image by the detection model, outputting the detected detection image, and finally obtaining a prescription chart of geographic position information of the dead tree of the pine wood nematode disease according to the coordinate position of the dead tree in the image. According to the method, the sick pine tree can be rapidly, efficiently and accurately detected, and the position of the sick pine tree is judged, so that subsequent treatment is facilitated.

Description

technical field [0001] The present invention relates to a dead tree detection method of pine wood nematode disease, in particular to a deep learning-based detection and positioning method of dead tree disease of pine wood nematode disease. Background technique [0002] Pine wood nematode disease is a devastating epidemic of pine trees that is extremely harmful to pine forests in my country. The external symptoms of infected pine trees are that the needles gradually turn yellowish brown, and the needles of severely diseased pine trees will turn reddish brown. , eventually wilting and dying. Pine wood nematode disease is highly pathogenic and has a fatal impact on the host. Often the infected pine tree will die soon and will quickly spread to other pine trees. The spread leads to the death of a large number of pine trees. Therefore, if the pine trees with pine wood nematode disease cannot be detected and treated in time, it will bring huge economic losses and certain damage to...

AI Technical Summary

Problems solved by technology

At present, the method of detecting and controlling pine wood nematode disease in my country is usually to go to the pine forest manually to find the diseased pine trees, and then apply pesticides and cut down the pine trees. This method not only consumes manpower and material resources, but also is not efficient. Obviously, this is not the best detection and management methods
