1. A feces color-based remote sensing estimation method for Antarctic bird population size, comprising the following steps:
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 in the remote sensing image, based on the reflectance value range of the mixture;
classifying the sample mixture area into a plurality of grade areas and determining an area of each grade area, based on the obtained reflectance value of the sample mixture area, comprising:
determining a proportion of the new feces of the sample mixture area, based on the obtained reflectance value of the sample mixture area;
classifying the sample mixture area into the plurality of grade areas and determining the area of each grade area, based on the obtained proportions of the new feces; and
generating a one-to-one correspondence of a density of birds in each grade area of the plurality of grade areas, based on the determined area of each grade area and an obtained number of birds in each grade area; and
wherein the step of determining the reflectance value range of the mixture of the new feces and the old feces in the remote sensing image comprises:
determining two interest areas for the new feces and the old feces in the remote sensing image; and
determining the reflectance value range of the mixture of the new feces and the old feces based on two obtained reflectance values of the two interest areas for the new feces and the old feces.
