Abstract

The invention discloses a determination method of disaster-affected grades of Chinese white pines and a determination system thereof. The determination method comprises following steps of S1: shootingsample place images of the Chinese white pines through a camera carried by an unmanned aerial vehicle; S2: by use of the type-two fuzzy clustering algorithm, carrying out region segmentation on the disaster-affected Chinese white pines in the sample place images of the Chinese white pines and calculating the specific value of the regions of the disaster-affected Chinese white pines to the sampleplace images of the Chinese white pine; and S3: by combining the leaf loss rate obtained through the ground investigation statistics, judging the disaster-affected grade of the Chinese white pines.

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...
