Method for investigating marmot density

Abstract

The invention discloses a marmot density survey method, which comprises the following steps: S1, according to a plague monitoring task, investigators select monitoring areas in respective areas according to actual conditions; s2, planning a flight route of the unmanned aerial vehicle according to factors such as landforms, setting flight parameters of the unmanned aerial vehicle and various photographing parameters of the pan-tilt camera, and performing image acquisition; s3, de-weighting and deleting the image data acquired by the unmanned aerial vehicle, and then splicing the image data into a global image; s4, copying the processed global image to a system terminal server through a storage device, or logging in the system through an authorized account to remotely upload; and S5, intelligently and automatically identifying the number of marmots in the uploaded image, and calculating the marmot density according to the area. According to the invention, the number, distribution and density of marmots can be totally counted through the unmanned aerial vehicle remote sensing technology and the intelligent identification technology, the coverage range is wide, the accuracy of the statistical result is high, and the standard unification of monitoring data is realized.

Description

technical field [0001] The invention belongs to the technical field of animal investigation, in particular to a method for investigating the density of marmots. Background technique [0002] Plague is a natural focal disease. It is a severe infectious disease characterized by rapid onset, rapid spread, short course of disease, high fatality rate and strong infectivity. It is a Class A infectious disease and has occurred three times in human history. The plague pandemic has brought a tragic disaster to the people of the world. [0003] The Himalayan marmot, as the most important source of infection and the storage host of Yersinia pestis, has a distribution area of ​​about 340,000 square kilometers in Qinghai Province. 2 . In accordance with the requirements of the National Plague Surveillance Program and the Qinghai Plague Surveillance Program, corresponding regulations were made for the investigation of the number and density of Himalayan marmots in the survey content.

Problems solved by technology

[0004] However, due to the huge area of ​​the plague foci in Qinghai Province, the diverse environment in the territory, the extremely inconvenient transportation, and the sparse population distribution, etc., the plague monitoring work in the province is very difficult. In addition, due to the limited number of rodent prevention professionals, the plague monitoring method is single and the monitoring coverage is limited. The area ratio is small and the work efficiency is limited

In addition, in the actual plague monitoring work, it is very easy to be limited by factors such as terrain, climate change, and the technical level of the monitoring personnel, which affects the comprehensiveness, accuracy and scientific nature of the plague monitoring work
