LIO-HKDT: Fast and Accurate LiDAR-Inertial Odometry With Hash K-D Tree
LiDAR-inertial odometry(LIO) has been widely applied in intelligent robotics and autonomous driving, providing high-precision and low-latency ego-motion estimation. However, the massive point clouds generated by LiDAR introduce intensive data processing demands, making k-nearest neighbor(KNN) search
