Description

technical field [0001] The invention belongs to the technical field of bionic navigation, in particular to a system and method for atmospheric polarization mode detection and heading calculation. Background technique [0002] Due to the scattering, radiation and absorption of tiny particles suspended in the atmosphere, the sunlight is polarized during the transmission process, and the polarization state distribution formed by polarized light is called the atmospheric polarization mode. The atmospheric polarization mode is related to factors such as time and location, and has the characteristics of continuous distribution in time and space, and the distribution characteristics of this polarization mode are relatively stable. [0003] There are certain defects in the traditional navigation methods, and the traditional navigation methods themselves have matured, and it is difficult to have a greater breakthrough. Therefore, human beings must seek a new method to further improve...

Problems solved by technology

However, the current polarized light detection system has a complex structure, mostly uses serial ports and USB ports for data communication, has limited real-time performance, and cannot display the specific operations of each step in the process of extracting polarization information in detail. It is relatively difficult to view the processing process and results of image data in real time. difficulty
