An Alternative to Using the 3D Delaunay Tessellation for Representing Freespace
(1989-09-01)
Representing the world in terms of visible surfaces and the freespacesexisting between these surfaces and the viewer is an important problemsin robotics. Recently, researchers have proposed using the 3DsDelaunay ...
Location Recognition Using Stereo Vision
(1989-10-01)
A mobile robot must be able to determine its own position in the world. To support truly autonomous navigation, we present a system that builds and maintains its own models of world locations and uses these models to ...
Visual Navigation: Constructing and Utilizing Simple Maps of an Indoor Environment
