It fuses LiDAR feature points with IMU data using a tightly-coupled iterated extended Kalman filter to allow robust navigation in fast-motion, noisy or cluttered environments where degeneration occurs. Our package address many key issues: @@ -94,7 +97,7 @@ A. Please make sure the IMU and LiDAR are **Synchronized**, that's important. B. The warning message "Failed to find match for field 'time'." means the timestamps of each LiDAR points are missed in the rosbag file. That is important for the forward propagation and backwark propagation. -C. Recommend to set the **extrinsic_est_en** to false if the extrinsic is give, as the online extrinsic calibration always requires much excitations to convergence. +C. We recommend to set the **extrinsic_est_en** to false if the extrinsic is give. As for the extrinsic initiallization, please refer to our recent work: [**Robust and Online LiDAR-inertial Initialization**](https://arxiv.org/abs/2202.11006). ### 3.1 For Avia Connect to your PC to Livox Avia LiDAR by following [Livox-ros-driver installation](https://github.com/Livox-SDK/livox_ros_driver), then
