Apparatus and method which provides for the determination of a vehicle's orientation and position in an environment, such as a hallway, from an image of ceiling lights. A mobile robot 10 includes a camera 12 that is pitched up obliquely at an intermediate angle between a horizon and a zenith. The camera views a ceiling having one or more ceiling lights 16 which may be of rectangular shape and which are preferably aligned with an axis of the hallway. In that the lights present a pattern or alignment which is substantially parallel to or perpendicular to a long axis of the hallway the pattern is detected an processed to derive robot navigation information therefrom. |
