Description

technical field [0001] The invention relates to a modeling of atmospheric polarization mode based on imaging theory and a method for analyzing its distortion degree, which belongs to the field of optical remote sensing research. Background technique [0002] After sunlight enters the atmosphere, it is polarized by the scattering and absorption of the atmosphere during the transmission process, and further forms a sky polarization mode with a stable distribution. The polarization information contained in this polarization pattern of the sky can be used as a source of navigation information for different animals. For example, sand ants, locusts, bees and other organisms can use their unique compound eye structure to perceive the polarization pattern of the sky and provide them with accurate compass information to achieve navigation capabilities. . Bionic polarized light navigation is an autonomous navigation method based on the highly sensitive polarization visual perception ...

Problems solved by technology

However, the current atmospheric polarization mode characterization model does not fully describe this process after the distortion of the imaging system

In particular, the change of the optical path of the polarization characteristics by the fisheye lens is ignored, which to a large extent caused the inaccuracy of the atmospheric polarization model, resulting in a large difference between the theoretical model and the actual atmospheric polarization model.
