Robust and online lidar-inertial
WebFeb 22, 2024 · In this paper, we propose a full and online LiDAR-inertial system initialization process that calibrates the temporal offset and extrinsic parameter between LiDARs and IMUs, and also the gravity vector and IMU bias by aligning the state estimated from LiDAR measurements with that measured by IMU. WebLiDAR(-inertial) Odometry. Many recent works on 3D LiDAR odometry and mapping are based on the LiDAR-odometry and mapping (LOAM) structure, where raw LiDAR points are accumulated into a frame (also called a scan) to extract feature points (e.g., edge and plane). The extracted feature points are then registered to the previous scan to produce …
