Abstract
A feces color-based remote sensing estimation method and apparatus for Antarctic bird population size is disclosed, which comprises: determining a reflectance value range of a mixture of new feces and old feces in a remote sensing image; determining a sample mixture area where the mixture is located, based on the reflectance value range of the mixture in the remote sensing image; classifying the sample mixture area into a plurality of grade areas and determining an area of each grade area based on an obtained reflectance value of the sample mixture area; and generating a one-to-one correspondence between a density of birds of each grade area in the sample mixture area and the each grade area, based on the area of the each grade area and an obtained number of birds in the each grade area.
