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 navigation During the behavior process, the acquisition of direction information is not completely limited to the two-dimensional plane. In most cases, the navigation carrier is in a non-horizontal state, and it is necessary to provide three-dimensional spatial information for the navigation of the carrier.
