Die Erfindung betrifft ein geodätisches Gerät, insbesondere ein geodätisches Fernrohr, beispielsweise für einen Theodoliten, oder geodätische Übersichts-, Photogrammetrie-oder Axialkamera, mit einem, eine optische Achse (A) definierenden, abbildenden optischen System (1) mit einem Beobachtungsstrahlengang zur Abbildung eines Zielobjekts durch ein Okular (128) und/oder auf einen Kamerasensor, zur Erfassung und/oder Bereitstellung eines Bildes des anvisierten Zielobjekts. Erfindungsgemäß umfasst das abbildende optische System (1) mindestens zwei diffraktive optische Elemente im Beobachtungsstrahlengang.
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.
