Vision-Based Semantic-Map Building and Localization
نویسندگان
چکیده
A semantic-map building method is proposed to localize a robot in the semantic-map. Our semantic-map is organized by using SIFT feature-based object representation. In addition to semantic map, a vision-based relative localization is employed as a process model of extended Kalman filters, where optical flows and Levenberg-Marquardt least square minimization are incorporated to predict relative robot locations. Thus, robust SLAM performances can be obtained even under poor conditions in which localization cannot be achieved by classical odometry-based SLAM.

Building 3d Maps with Semantic Elements Integrating 2d Laser, Stereo Vision and Imu on a Mobile Robot
Building 3D models is important in many applications, ranging from virtual visits of historical buildings, game and entertainment, to risk analysis in partially collapsed buildings. This task is performed at different scales: city, buildings, indoor environments, objects and using different sensors: cameras, 2D and 3D laser, etc. Moreover, different map representation have been considered: metr...
متن کاملSimultaneous Localization and Map-Building Using Active Vision
ÐAn active approach to sensing can provide the focused measurement capability over a wide field of view which allows correctly formulated Simultaneous Localization and Map-Building (SLAM) to be implemented with vision, permitting repeatable longterm localization using only naturally occurring, automatically-detected features. In this paper, we present the first example of a general system for a...

Personal location information is regarded as the most important contextual information transmitted in ubiquitous systems. Many pedestrian indoor localization systems rely on mapmatching to constrain sensor errors. The maps required for computer aided localization and tracking need to incorporate a semantic structure. Such maps are not available on a larger scale and therefore most groups workin...

When service robots carry on mission planning and execution, they not only need structural information about the environment to navigation and localization, but also need to possess deeper knowledge to endow a robot with higher degrees of autonomy and intelligence. However it is hard for a robot to cognize the semantic description such as the function attributes of objects and rooms only relyin...
متن کاملRecent advances in simultaneous localization and map-building using computer vision
Simultaneous localization and map-building (SLAM) continues to draw considerable attention in the robotics community due to the advantages it can offer in building autonomous robots. It examines the ability of an autonomous robot starting in an unknown environment to incrementally build an environment map and simultaneously localize itself within this map. Recent advances in computer vision hav...
