Embodiment 1

[0033] This example proposes a remote sensing estimation method for Antarctic bird populations based on the color of excrement. In this embodiment, the reflectance value range of the mixture of old and new dung can be calculated first through remote sensing images, and the one-to-one correspondence between each level and the bird density in the sampling mixing area of ​​old and new dung, so that in practical applications , for large-area remote sensing images of Antarctic birds to be counted, we can first classify the mixed areas to be counted in the remote sensing images, and then according to the area of ​​each class area and the reflection of the mixture of old and new dung calculated in advance Rate value range, and the one-to-one correspondence between each level in the sampling mixed area and the bird density, calculate the number of birds corresponding to each level area in the large-area remote sensing images of Antarctic birds to be counted, and finally get the number ...

Embodiment 2

[0079]This example proposes the application of a remote sensing method for estimating Antarctic bird populations based on the color of excrement. The reflectance value range of the mixture of old and new dung has been calculated from the small-area sampling remote sensing images of Antarctic birds in Example 1, and the one-to-one correspondence between each grade and the bird density in the sampling mixture area of ​​old and new dung, then , in this embodiment, for the remote sensing image of a large area of ​​Antarctic birds to be counted, the reflectance value range of the mixture of old and new dung calculated in Embodiment 1 can be used, as well as the density of birds of each level in the sampling mixed area The one-to-one correspondence relationship realizes the calculation of the number of birds in the remote sensing images to be counted.

[0080] It should be noted that the research area in this example belongs to the same area as the research area described in Example...

Embodiment 3

[0102] The present invention proposes a remote sensing estimation device for Antarctic bird population based on the color of excrement, referring to Image 6 , Image 6 It is a schematic diagram of the structure of the remote sensing estimation device for Antarctic bird population based on the color of excrement soil of the present invention. like Image 6 As shown, the remote sensing estimation device of Antarctic bird population based on the color of excrement includes:

[0103] The sampling module 30 is used to determine the reflectance range of the mixture of old and new dung in the remote sensing image;

[0104] The comparison module 40 is used to determine the sampling mixing area where the mixture is located in the remote sensing image according to the reflectance value range of the mixture;

[0105] The division module 50 is configured to divide the sampled mixed area into multiple grades according to the acquired reflectance value of the sampled mixed region, and d...

Abstract

The invention provides a remote sensing estimation method and device for the population number of Antarctic birds based on the color of manure soil, and the method comprises the steps: determining a reflectivity value interval of a mixture of new and old manure soil in a remote sensing image; according to the reflectivity value interval of the mixture, determining a sampling mixing area where the mixture is located in a remote sensing image; dividing the sampling mixing area into a plurality of grades according to the obtained reflectivity value of the sampling mixing area, and determining the area of each grade of area; and according to the area of each grade area and the obtained number of birds in each grade area, generating a one-to-one correspondence relationship between the bird density of each grade area in the sampling mixing area and each grade. According to the method, the quantity of the Antarctic bird populations can be counted with high precision on the premise of not influencing the Antarctic ecological environment and bird behaviors.

Description

technical field [0001] The invention relates to the technical field of animal remote sensing, in particular to a remote sensing estimation method and device for Antarctic bird populations based on the color of excrement. Background technique [0002] As the last "pure land" in the world, Antarctica has attracted the attention of more and more countries in recent years because of its rich natural resources and inherent scientific research and aesthetic values. However, the ecological environment of Antarctica is extremely fragile, and studying the number of Antarctic bird populations plays an important role in revealing the ecological environment of Antarctica in recent years. [0003] At present, the number of Antarctic bird populations can be obtained by manual counting. However, this method is often affected by adverse factors such as time, distance, and danger, resulting in large errors in calculation results. ecological damage. Contents of the invention [0004] The ...
