Three-dimensional attitude acquisition method based on space characteristics of atmospheric polarization mode

Abstract

The invention relates to a three-dimensional attitude acquisition method based on space characteristics of an atmospheric polarization mode. The method is characterized by comprising the following steps of: acquiring a three-dimensional space attitude according to a distribution rule of the atmospheric polarization mode; on the basis that a three-dimensional space coordinate system of the atmospheric polarization mode and a coordinate system of a navigation carrier are established, acquiring the space information of a space remarkable characteristic point of the atmospheric polarization mode; and by measuring the space position change of the space remarkable characteristic point, solving a three-dimensional attitude angle dynamic measurement equation of the navigation carrier to realize acquisition of the three-dimensional attitude information of the navigation carrier. The invention provides the three-dimensional attitude acquisition method for the navigation carrier and is applicable to navigation and positioning of three-dimensional polarized light.

Description

technical field [0001] The present invention relates to the technical fields of intelligent information acquisition and processing and bionic navigation, and is a method for obtaining a three-dimensional attitude based on natural polarization characteristics, in particular to a three-dimensional attitude measurement using several feature points of atmospheric polarization mode information, thereby performing three-dimensional space navigation and navigation. method of positioning. Background technique [0002] Navigation technology is widely used in both civil and military fields. With the advancement of science and technology and the development of navigation technology research, the navigation method based on the natural properties of the earth has been widely concerned because of its strong anti-interference ability and the characteristics that it is not easily affected by human factors. The bionic polarized light navigation method is an autonomous navigation method base...

Problems solved by technology

[0005] In the existing theory of bionic polarized light navigation methods, they are all aimed at the acquisition of direction information on a two-dimensional plane. The research is based on the assumption that the navigation carrier is always kept horizontal for the detection of polarization information and the acquisition of direction. However, in actual n
