WebMar 26, 2024 · Abstract. Point cloud registration is the basis of real-time environment perception for robots using 3D LiDAR and is also the key to robust simultaneous localization and mapping (SLAM) for robots. Because LiDAR point clouds are characterized by local sparseness and motion distortion, the point cloud features of coal mine roadway … WebApr 12, 2024 · The IMU preintegration should start from the state of last lidar scan. However, the state of lidar named "g_lio_state" is also updated in r3live_vio.cpp. So the initial state in the function ImuProcess::lic_point_cloud_undistort is the state of the closest image frame, not the state of last lidar scan. phillips house chocolates https://politeiaglobal.com
