The method comprises the steps that 1, according to a Rayleigh model, the atmospheric polarization mode is constructed; 2, the difference of the atmospheric polarization mode under the condition of a similar imaging theory and an actually collected non-similar imaging theory is analyzed; 3, alight-path transmission characteristic of a polarization imaging system with the atmospheric polarization mode is analyzed and acquired; 4, according to the light-path transmission characteristic of the polarization imaging system, the modeling method of the atmospheric polarization mode based on the imaging theory is constructed; 5, according to the model, the distortion degree of the atmosphericpolarization mode under the polarization imaging system is calculated. According to the modeling method of the atmospheric polarization mode based on the imaging theory, under the conditions of different imaging systems, different sun positions, different observation positions and the like, reasonable description for the atmospheric polarization mode in the actual sky can be achieved, the precision of polarization data calculation is facilitated, and a new idea is also provided for construction of a more accurate and analyzable atmospheric polarization mode representation model.

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.
