摘要
基于自然特性的导航科学具有重要的研究与应用价值,本文针对仿生导航技术中的航向获取问题,研究了一种基于大气偏振模式对称性检测的航向角获取方法。文章在大气偏振模式分布具有对称性及稳定性基础上,对大气偏振模式图像进行对称性检测,确定大气偏振模式对称轴即太阳子午线位置,进而解算出航向角信息,并通过实验验证了所述方法的有效性。本文提出的基于大气偏振模式对称性检测的航向角获取方法是仿生偏振光导航的重要研究内容,对基于自然特性的导航方法研究,具有重要的指导意义。
Navigation science based on natural features receives wide attention.In this paper,a method is proposed to acquire the navigation direction angle based on the symmetry detection of the atmosphere polarization mode.Using the symmetry of the distribution of atmospheric polarization mode and according to the test results of the symmetry,the radial position of the sun is determined,and then the navigation heading angle information is calculated.At last,the corresponding experiment is also given to test the method.The method of the navigation direction angle acquisition based on the symmetry detection of the atmosphere polarization mode,is very important in the research of bionic polarization navigation,and has the important practical significance for the navigation methods and strategies based on natural characteristics.
