G-ICP SLAM: An odometry-free 3D mapping system with robust 6DoF pose estimation
2015
The paper proposes an
odometry-free 3D mapping system that combines a LIDAR and a inertial sensor. The proposed system achieved robust 6DoF pose estimation for arbitrary motion and is implemented as a hand-held unit to make use of simplified
mobile mappingapplications. The pose estimation algorithm is based on " Velodyne
SLAM" which is a state of the art ICP based
SLAM(
Simultaneous Localizationand
Mapping) method using only
point clouddata. We added 3DoF inertial information to process the
point cloudcorrection and the position prediction. Compared to the previous method, the proposed method is robust to rotary motion and works for fast and large change of sensor position and orientation. The results
demonstrate effectiveoperation in various environments and we confirmed the improvement of the self-position estimation and mapping performance.
