Abstract:
This paper describes a visually guided robot that can plan paths, construct
maps and explore an indoor environment. The robot uses a trinocular stereo
vision system to produce highly accurate depth images at 2 Hz allowing it
to safely travel through the environment at 0.5 m/s. The algorithm
integrates stereo vision, occupancy grid
mapping, and potential field path planning techniques
to form a robust and cohesive
robotic system for mapping and navigation. Stereo vision is shown to be a
viable alternative to active sensing devices such as sonar and laser range
finders.
