Robust Real-time LiDAR-inertial Initialization

A robust and real-time LiDAR-inertial initialization method, which can efficiently calibrates the temporal offset and the extrinsic parameter between LiDAR and IMU, and can initialize the gravity vector and IMU bias. Our paper is available at arxiv.org/abs/..., the project code and test data will be open sourced on Github: github.com/hku....
