Multi-hypothesis localization with a rough map using multiple visual features for outdoor navigation

Abstract: We describe a method of mobile robot localization based on a rough map using stereo vision, which uses multiple visual features to detect and segment the buildings in the robot's field of view. The rough map is an inaccurate map with large uncertainties in the shapes, dimensions and locations of objects so that it can be built easily. The robot fuses odometry and vision information using extended Kalman filters to update the robot pose and the associated uncertainty based on the recognition of buildings in the… Show more

“…The simulated robot move away from the starting position, turns at the subgoals and stops at the destination position in the figure. Since we are using our previous method of multi-hypothesis localization [11], the detailed strategy of the simulated motion is as follows: When the robot recognized a subgoal or a destination, its pose hypothesis would be reserved. When the robot failed to recognize a goal, it travels over more distances searching for the goal.…”
