There have been great advances in recent years in the area of
indoor navigation. Many of these new navigation systems rely on
digital images to aid an inertial navigation estimates. The Air
Force Institute of Technology (AFIT) has been conducting research
in this area for a number of years. The image-aiding techniques are
centered around tracking stationary features in order to improve
inertial navigation estimates. Previous research has used stereo
vision systems or terrain constraints with monocular systems to
estimate feature locations. While these methods have shown good
results, they do have drawbacks. First, as unmanned exploration
vehicles become smaller in size the distance available to create a
baseline between two cameras decreases resulting in a decrease of
distancing accuracy. Second, if using a monocular system, terrain
data might not be known in an unexplored environment. This research
explores the use of a small gimbaled laser range sensor and
monocular camera to estimate feature locations.
