This paper describes a new approach to SLAM problems using low quality range data. Vision sensors are useful for acquiring various kinds of environmental information but range data obtained by stereo vision is less reliable than other active sensors like laser range finders. False stereo matches often result in spurious obstacles, which may degrade the map when directly used in existing SLAM methods...
This paper describes a stereo-based person tracking method for a person following robot. Many previous works on person tracking use laser range finders which can provide very accurate range measurements. Stereo-based systems have also been popular, but most of them are not used for controlling a real robot. We previously developed a tracking method which uses depth templates of person shape applied...
Mapping is an activity of making a useful description of an environment. Not only geometric information such as free space but also object placements are important if the map is used for human-robot communication. We call such a map making environment information summarization because how to summarize may change depending on the purpose of the map. Environment information summarization usually includes...
This paper describes a vision-based interface for instructing robot motion easily. An interface that makes the robot move in the same way as user's motion is effective for an intuitive motion instruction. Such an interface can be realized by estimating the pose (position and orientation) of the interface and executing move commands for making the robot take the same pose.We estimate the pose of the...
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, the dimensions and the locations of objects so that it can be built easily. The robot fuses odometry and vision information using extended...
