Beschreibung
Zusammenfassung:	A method for moving an optical device of an imaging device includes one or more depth sensors acquiring one or more depth measurements within a predefined spatial coordinate system. Each of the one or more depth measurements indicates a distance from the imaging device to an object within the predefined spatial coordinate system. The method further includes one or more orientation sensors determining orientation information of the imaging device within the predefined spatial coordinate system, estimating an object distance between the imaging device and the object based on the one or more depth measurements and the orientation information, and moving the optical device from a first position to a second position according to the object distance and a focal length of the optical device.
