Pine wood nematode disease withered tree detecting and positioning method based on high-altitude pan-tilt recognition

Abstract

The invention discloses a pine wood nematode disease withered tree detecting and positioning method based on high-altitude pan-tilt recognition, and the method comprises the following steps: determining a detection target region, employing a high-altitude pan-tilt camera to obtain the surrounding environment in the detection target region, and generating PTZ scanning information; positioning a photographing position of a camera according to the PTZ scanning information to generate a to-be-identified image; the high-altitude cradle head performing CNN model identification on the to-be-identified image in the image capture queue Q1, and extracting a suspicious image; the high-altitude holder controlling the camera to perform re-shooting and re-identification on the corresponding position according to the suspicious image, and locking the PTZ coordinate position of the withered tree in the suspicious image; and determining longitude and latitude information of the corresponding camera according to the PTZ coordinate position of the withered tree in the suspicious image, and calculating the geographic position longitude and latitude of the withered tree. The beneficial effects are that high-altitude shooting, image identification and accurate positioning of death trees caused by pine wood nematode diseases are realized, and the direction is guided for patrol.

Description

technical field [0001] The invention relates to the technical field of forest protection, in particular to a method for detecting and locating dead trees with pine wood nematode disease based on high-altitude cloud platform identification Background technique [0002] Pine wilt disease, also known as pine wilt disease, is a devastating forest disease caused by pine wood nematode (Bursaphelenchus xylophilus). . Since the disease was introduced into my country in 1982, it has spread rapidly. At present, more than 14 provinces (cities, districts) have occurred in the country, covering an area of ​​77,000 hectares. It has caused a large number of pine trees to die. It has caused serious damage and caused serious economic and ecological losses. According to reports, in 2017 alone, my country's pine wood nematode disease caused economic losses of about 19.5 billion yuan, of which 3.5 billion yuan were direct economic losses and 16 billion yuan were indirect economic losses. Pine ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the defect of prior art is: lack a kind of technology that can be cheap, in time, recyclable, and human participation is little, conveniently detects and locates the dead tree of existing pine wood nematode disease
