Pine wood nematode disease, withered and dead tree detection method based on two-stage high-altitude holder video

Abstract

The invention discloses a pine wood nematode disease, withered and dead tree detection method based on a two-stage high-altitude holder video, which comprises a first stage and a second stage, in the first stage, a PTZ value of an appearance position of a suspicious diseased and dead tree is directly and quickly positioned by using a video; and in the second stage, the suspicious diseased and dead trees are photographed again, and further identification processing is carried out by adopting a pine wood nematode disease withered and dead tree CNN classification algorithm. According to the method, diseased and dead trees are quickly positioned through the high-altitude holder video, and then the pine wood nematode disease withered and dead trees are classified and identified through shooting again, so that the withered and dead tree identification process of the forestry high-altitude fireproof holder can be greatly accelerated, and the accuracy of an identification result is further improved; any new equipment does not need to be added to the front end, and the device can be cooperated with the function of the high-altitude fireproof holder.

Description

technical field [0001] The invention relates to the technical field of forest protection, in particular to a method for detecting dead trees with pine wood nematode disease based on two-stage high-altitude cloud platform video. Background technique [0002] Pine wood nematodes belong to the phylum Nematozoa, the orders of the order, the superfamily, the family of the family, and the genus of the genus. It is one of the more harmful invasive alien species in China (but it is not included in the list of the first batch of invasive alien species in my country). Pine wood nematode disease has occurred in the United States, Canada, Mexico, Japan, South Korea and other countries. In the 1980s, it invaded Hong Kong, China, and almost destroyed the extensive Pinus massoniana forests in Hong Kong. It was first discovered in Nanjing Sun Yat-sen Mausoleum in 1982, and then successively formed several disease centers in Anhui, Shandong, Zhejiang, Guangdong and other places, and spread ...

AI Technical Summary

Problems solved by technology

At present, the method of detecting and controlling pine wood nematode disease in my country is usually based on manual patrolling, but because many nature reserves are inaccessible, it is difficult to achieve the purpose of early detection and early treatment

[0005] The defect of the existing technology is: some research institutions use drones to patrol forest farms and use corresponding algorithms to identify them. However, drones have technical problems with limited patrol range and require human participation throughout the process; The existing high-altitude platform is used to detect the dead trees of pine wilt nematode disease, not through video, but fixed-point photography to achieve it. The method is time-consuming and may affect the normal fire prevention target of the high-altitude platform.
