PROJECT TITLE :

Attitude Determination Based on Location of Astronomical Markers With Skylight Polarization Pattern

ABSTRACT:

Many social insects, like desert ant and honeybees, will be able to utilize the natural skylight polarization information for navigation, that has blessings in immunity to the interference of external surroundings and so shows higher stability and accuracy. Inspired by it, we attempt to explore a brand new bionic method for angle determination by use of polarization pattern. In observe, we tend to 1st capture the polarization information and based mostly on it, to work out the placement of the sun through clustering. Then, with respect to the relatively consistent spatio-temporal relation between the sun and the zenith, the placement of the zenith is accordingly determined. The coordinate of the zenith is adopted to determine the perspective rotation matrix and by that to figure out the vehicle's attitude. Finally, we tend to founded a simulation vehicle platform to test the effectiveness of the approach with the theoretical polarization pattern derived from the Rayleigh single-scattering theory and actually detected pattern by the polarization analyzer.
