Abstract

The invention discloses a method for judging the damage level of Chinese pine and its judging system, wherein the judging method includes the following steps: S1: taking images of Chinese pine samples with a camera mounted on a drone; S2: using a type-two fuzzy clustering algorithm Segment the damaged Chinese pine in the image of the Chinese pine plot, and calculate the ratio of the affected Chinese pine area to the Chinese Chinese pine sample area; S3: judge the damage level of Chinese pine based on the leaf loss rate of the ground investigation and statistics.

Description

technical field [0001] The invention relates to the technical field of prevention and control of forest diseases and insect pests, in particular to a method for judging the damage level of Chinese pine and a judging system thereof. Background technique [0002] Forest pests and diseases are the primary factors that threaten forest health. The occurrence of forest diseases and insect pests in my country is very serious, and the disaster rate of forestry pests and diseases is much higher than the average level in the world, which has brought a huge impact on my country's ecological environment construction and forestry production. How to monitor and prevent forest diseases and insect pests has been an important topic studied by forestry experts at home and abroad for many years. There are three main monitoring methods for traditional forestry pests and diseases: 1. Regularly arrange forest farm staff to conduct manual inspections of key forest areas that are vulnerable to disa...
