Bird investigation method and device

Abstract

The invention relates to a bird investigation method and device. The bird investigation method comprises the steps of obtaining remote sensing image data and storing the remote sensing image data in amobile terminal; marking the position point of the bird and the position point of the interference source in the remote sensing image data displayed by the mobile terminal; and calculating the actualdistance between the position point of the bird and the position point of the interference source. According to the invention, the distance between birds and human interference sources such as roadsand residential areas can be accurately measured, the investigator can accurately understand and know the survival condition of the species, the investigator does not need to reach the bird living site, the working intensity and safety risk of the investigator are reduced, interference to birds is avoided, and the quality and accuracy of wetland waterfowl investigation and monitoring results are remarkably improved.

Description

Technical field [0001] This application relates to the technical field of bird ecology research, especially a bird survey method and device. Background technique [0002] Investigation and monitoring are the main ways to understand the dynamics and management of species populations, as well as the daily work of various protected areas, national parks and other protected areas. Using sample lines and sample points to conduct ground surveys is a conventional method for bird resource surveys. The sample line method means that the observer travels along the sample line at a certain speed while recording the individual birds found on both sides of the sample line (including what they see and hear). The spot method means that the observer stays at a predetermined interval selected in advance for 5-10 minutes, and counts the birds found in a certain range around it. When using the sample line or sample point method to conduct bird surveys, it is necessary to locate the bird's position....

AI Technical Summary

Problems solved by technology

[0003] In order to overcome at least to a certain extent the distance between birds and man-made disturbance sources such as roads and residential areas, which cannot be measured by traditional positioning methods, it can only be estimated by investigators based on experience, resulting in errors in positioning or survey data, resulting in the inability to accurately recognize species. The living conditions of birds also make the research results of bird space use and behavior deviate. This application provides a bird survey method and device
