Abstract: A method and apparatus for robust localization in outdoor environments is provided. The localization method includes the steps of receiving scanner data from localization means and receiving angle information of a mobile device from an angle sensor, correcting the scanner data based on the received angle information, performing an Iterative Closest Point (ICP) mechanism for the corrected scanner data and generating a first constraint, and localizing the mobile device based on a graph structure under the first constraint.

Abstract: An underground localization method and a system therefor are provided. The underground localization method includes computing location information of a dead reckoning using a gyro sensor and a distance movement sensor of moving equipment, measuring physical information according to the computed location information of the dead reckoning and searching for the physical information which is determined as being matched with the location information of the dead reckoning, and optimizing a location by reflecting location information of the physical information which is determined as being matched with the location information of the dead reckoning.

Abstract: A method for estimating 6-DOF relative displacement using vision-based localization and apparatus therefor are disclosed. A method for estimating 6-DOF relative displacement may include acquiring images of a first marker attached to a fixing member and a second marker attached to a dynamic member for assembling to the fixing member by using a camera, extracting a feature point of the first marker and a feature point of the second marker through image processing for the acquired images, and estimating 6-DOF relative displacement of the dynamic member for the fixing member based on the extracted feature point of the first marker and feature point of the second marker.

Abstract: Robust laser scanner matching method and device considering a movement of a ground robot are disclosed. A scan matching method according to an embodiment of the inventive concept includes receiving two point clouds, sequentially inspecting height values until a point is within a specific height range to search for correspondence points between the two point clouds, and performing scan matching between the two point clouds based on the search result of the correspondence points.
