Abstract
Ranges of objects are determined using a camera equipped with a rotating optical axis displacement unit (ODU). The ODU receives light about an offset line of sight, and displaces it to a substantially parallel camera line of sight. The displaced light is focussed onto an image sensor. Images of a scene are captures as the ODU rotates. Range information is calculated from the apparent motion of objects in the captured images.
