Method for identifying number of adel penguins based on high-resolution remote sensing image

Abstract

The invention discloses a method for identifying the number of adel penguins based on a high-resolution remote sensing image. The method comprises: obtaining a remote sensing image with a preset resolution, preprocessing a remote sensing image, extracting the total number of shadow pixels of the Adel penguin from the remote sensing image by using an object-oriented method, calculating the averageshadow pixel of the Adel penguin, and calculating the number of the Adel penguin in the remote sensing image according to the total number of the shadow pixels and the average shadow pixel of a singlepenguin. According to the technical scheme provided by the invention, the accuracy of extracting the number of the penguins from the remote sensing image with the resolution can be improved, so thatthe number of the penguins is accurately monitored, and the problem that the number and the distribution pattern of the penguins are difficult to observe at the same time is solved. According to the technical scheme provided by the invention, the penguin population is monitored based on the high-resolution remote sensing image, the result precision and reliability are improved, the safety and convenience of field observation are greatly enhanced, and the application value is very high.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method for identifying the number of Adélie penguins based on high-resolution remote sensing images. Background technique [0002] Population refers to all individuals of the same kind of organisms occupying a certain space within a certain period of time. The population size is the sum of the number of individuals in the population, and it is the basis for calculating the population density, birth rate, death rate, immigration rate and emigration rate. Observing the population of Adélie penguins helps to reveal the changes in the population of Adélie penguins, and provides basic data support for related research on Adelie penguins and the feedback of Antarctic ecosystems to climate change. [0003] For a long time, the observation and counting of Adélie penguin populations and populations were mainly carried out through artificial field counting and remote sensing sate...

AI Technical Summary

Problems solved by technology

These methods are greatly affected by the experience of observers, and the identification accuracy of Adélie penguins is low, and they are easily disturbed by clouds in the image. There are large errors, and the economy and efficiency are not high.
