Abstract
An image-based sensor system for a mobile unit makes use of light emitters and imagers to acquire illumination patterns of emitted light impinging on the floor and/or walls surrounding the unit. The illumination pattern is used to estimate location and/or orientation of the unit. These estimates are used for one or more functions of stabilization, calibration, localization, and mapping of or with respect to the unit.
