SKY POLARIZATION SENSOR FOR ABSOLUTE ORIENTATION DETERMINATION |
摘要 |
A method for determining absolute orientation of a platform is disclosed. In one embodiment, a first sky polarization data set for a first time Ti is measured using a sky polarization sensor disposed on a platform. A second sky polarization data set is obtained at a second time Tj. A difference in orientation between the first sky polarization data set and the second sky polarization data set is determined using an orientation determiner. The difference in orientation is provided as at least one orientation parameter for the platform at time Tj. The at least one orientation parameter is used to provide a direction relative to a reference point on the platform. |
